Lidtke Endorphigen vs Doctor’s Best D-phenylalanine: the taste difference and endorphin boosting benefits for mood and cravings

April 19, 2024 By Trudy Scott 26 Comments

The amino acid d-phenylalanine (DPA) is used to boost endorphins in order to improve mood and reduce cravings. Lidtke Endorphigen has long been a favorite recommendation of mine for this purpose. Doctor’s Best D-phenylalanine is an equally effective and quality product, and both are ideally used opened onto the tongue. When DPA is used this way you get quick results. Many of my clients (and myself included) describe the opened DPA as a dark-chocolate bitter like taste that is not unpleasant. However, about half my clients don’t particularly like the taste of DPA and one woman in my community, Ali, was ready to give up on the Lidtke Endorphigen product because of the taste.

In today’s blog you can read her feedback comparing both products and what worked for her, feedback from a few other women about both products and my personal feedback – with all of us sharing results and taste. And I share some takeaway lessons from these DPA experiences.

She shared this about her strong aversion to the Endorphigen:

Oh goodness. If I open the Endorphigen on my tongue, it’s just awful. I might be able to get 1/4 of it but that’s it. And the taste stays there for at least an hour. No sense of chocolate in there for me. Isn’t that interesting that you and others like the taste. I consider myself pretty open to whatever needs to be done but wow, this is almost no way.

I shared how I love the taste of DPA and that it’s 50:50 in terms of loving it (chocolate-like taste) vs not loving it but also that using the amino acids opened is more effective for many folks. But it’s no good if it tastes bad. I also shared that Lidtke Endorphigen contains a small amount of vitamin B2 and vitamin B6 and maybe that was making it intolerable for her.

Doctor’s Best D-phenylalanine contains DPA only and when I let her know all this, Ali decided to give it a try. This is her feedback on the day she got it:

I received my Doctor’s Best D-phenylalanine and put it on my tongue. It’s 10 bazillion times better than the Endorphigen which was so bad for me that I couldn’t get past it. And I think I can get past a lot. I’m grateful. So now I have to see how it works for me.

Ali’s dark clouds have lifted and her sweet tooth has disappeared

The next day Ali posted this, amazed this product made such a difference in just one day:

I used the Doctor’s Best D-phenylalanine only once and that was today at about 8 am. I felt just generally better, no dark clouds. But also, it’s now 6:30pm when I get my sweet tooth. Nothing. Nothing at all. So no sweet tooth and an improved general feeling. I realize it’s only one day but I feel like it’s made a difference.

And a week later she posted this, confirming that Doctor’s Best D-phenylalanine “is a game changer”:

So much different from Endorphigen. I find I need only 1/2 capsule on my tongue. There’s not much of a taste to me. I then don’t want sweets like I have been wanting in the morning and evening. But I also have a better general feeling. Hard to describe but I just feel more grounded. I can’t tell if it physically reduces the sweet craving or if it’s a mental change. Or both. In any case, nice solid change. Thank you for being there.

Alicia also likes Doctor’s Best D-phenylalanine opened on to her tongue

She shared this about how this DPA product makes her feel:

It gives me a great feeling. Just getting me through some stressful moments. I recommend it! Opening onto the tongue is more effective than swallowing but swallowing adds a bit of relaxation too.

I don’t mind the taste at all – it reminds me of sugar or cocoa powder (my husband was less keen when I got him to try). And it works quickly, yes – I think within 10 minutes but probably less. And I feel more perky for hours. I think I feel more alert but calm emotionally.

I always have a bottle of DPA on hand and I shared my success with Doctor’s Best D-phenylalanine for a recent tooth issue/pain and emotional pain over the holidays on this blog post.

And yet many folks do well with Lidtke Endorphigen and like the taste

I’d like to be clear that this is not intended to be a negative post about Lidtke Endorphigen at all. I still recommend both products and I’ve personally used and like the taste of both. The purpose is to illustrate that we need to find what works for our unique needs and tastes.

As you can see, many folks do really well with the Lidtke product.

Lynn shared this: “I love using the DPA! I use the Lidke brand. Very helpful in improving mood and anxiety. Open on my tongue. I like the taste!”

Joan shared this: “It’s interesting to read your recommendation to open the capsule … I had just started doing that! (Already using powdered forms of other aminos) Anyone looking thru my trash might wonder what I’m up to. This method really works for me.” (she’s using the Lidtke brand).

The addition of vitamin B2 and vitamin B6 to the Lidtke DPA clearly makes no difference in these instances.

The takeaways from this post

DPA is effective for boosting mood and reducing cravings
DPA works more effectively when opened on to the tongue and you’ll see results more quickly
Don’t push through if a product tastes unpleasant
Don’t give up if one brand doesn’t work for you
What works for you may not work for someone else
We all have different taste perceptions – find what works for your unique needs and tastes
Product formulations change so keep track of exact ingredients on your log and check ingredients when you re-purchase a product

Both DPA products and where to find them

Doctor’s Best D-phenylalanine is available via iherb (use this link to save 5%). Lidtke Endorphigen is available from the company site and from my online store (Fullscript – only available to US customers – use this link to set up an account).

Update September 27, 2024

It appears there are issues with the supply of Doctor’s Best D-phenylalanine. As of now it’s no longer available on their website and nor is it available via iherb.

I emailed Doctor’s Best and received a very generic response and emailed again to try and find out if it’s a shortage or has been discontinued.

They replied to my 2nd email with this:

We appreciate your interest in the products that we offer. Unfortunately, our D-phenylalanine is temporarily out of stock and at this time, we do not have a specific restock date available. We apologize for the inconvenience.

We recommend checking back on our website periodically for updates on product availability. As soon as it is restocked, it will be listed on our website, and you’ll be able to place an order.

The problem is far from clear. Someone in the community reached out and shared this: “When I spoke to a DB representative on the phone, they told me the product was discontinued due to ‘supply chain issues,’ that they had not been producing it for some time, and that Lidtke was the only place they could redirect me. Sounds like they don’t even know in-house what the true status is.”

Let’s hope this is just a shortage. But either way, right now Lidtke Endorphigen is the only other company I know that offers DPA and because of the taste issue some individuals have with the Lidtke product, swallowing a capsule is going to be the best option. I have also reached out to Lidtke sharing the taste issue and this blog post, and asked if they would be willing to offer a DPA only product. I’ll keep you posted on the outcome (and thanks if you reached out to let me know your findings).

Update May 30, 2025

Unfortunately, Doctor’s Best D-phenylalanine has been discontinued. The good news is that Lidtke appreciated the fact that I shared your taste issues and feedback, and my request for a powder-only product of d-phenyalanine/DPA has come to fruition.

You can read more about this new DPA product on this blog post.

Additional resources when you are new to using DPA and other amino acids as supplements

As a reminder, low endorphins can cause low mood, weepiness, emotional pain, physical pain and emotional eating or cravings. As always, I use the symptoms questionnaire to figure out if low endorphins or other neurotransmitter imbalances may be an issue.

If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control (this is covered in an entire chapter too), sugar cravings, anxiety and mood issues.

The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs (over and above the DPA products I mentioned above).

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms too). This is a paid online/virtual group program where you get my guidance and community support.

If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. This is also a paid online/virtual program with an opportunity to interact with me and other practitioners who are also using the amino acids.

Wrapping up and your feedback

I do always appreciate feedback like this so keep it coming so more folks can get results.

Now I’d love to hear from you – how has DPA helped your mood and cravings (and pain too?)

Which product has worked well for you?

Do you find DPA is more effective if swallowed or as a capsule opened? And how do you describe the taste?

If you’re a practitioner do you use DPA with your clients/patients and have you had this feedback?

And please let me know if it’s helpful that I’m now including product recommendations and where to get them?

Using GABA to ease the visceral / abdominal pain and hypersensitivity of colitis, ease anxiety and reduce inflammation?

April 12, 2024 By Trudy Scott 13 Comments

Can the amino acid GABA be used as a supplement to ease the visceral (or abdominal) pain and hypersensitivity of colitis? And at the same time help to ease physical anxiety/tension, spasms and even reduce inflammation? A new animal study suggests this may be possible, with the authors stating “these results raise the promising possibility that GABA … may be an effective therapeutic strategy for the management of symptoms associated with colitis.”

Clinically we see that GABA does ease visceral pain in many digestive conditions and there is much evidence that it eases physical anxiety too. I share my personal experiences and feedback from someone in my community below.

What is especially exciting about this paper is that it’s specific for colitis and many markers of inflammation are favorably impacted by GABA supplementation too. The authors do state that human studies are needed to confirm this research. I look forward to these human studies and until then I say let’s use what we see clinically, based on symptoms and a trial of GABA.

Here is the paper: Experimental colitis-induced visceral hypersensitivity is attenuated by GABA treatment and the overview of their hypothesis:

Ulcerative colitis is linked with inflammation of the large intestine due to an overactive response of the colon-immune system. Ulcerative colitis is associated with weight loss, rectal bleeding, diarrhea, and abdominal pain.

Given that γ-amino butyric acid (GABA) suppresses immune cell activity and the excitability of colonic afferents, and that there is a decrease in colonic GABA during ulcerative colitis, we hypothesized that ulcerative colitis pain is due to a decrease in the inhibition of colonic afferents. Thus, restoring GABA in the colon will attenuate inflammatory hypersensitivity.

Colonic afferents are neurons that “carry information from sensory receptors of … organs” like the colon “to the central nervous system (i.e. brain and spinal cord).” They are involved in the perception of pain.

The study and favorable outcomes

They tested their hypothesis in a mouse model of colitis and GABA was given at the same time.

What they found is that GABA reduced the “increase in the colon permeability” i.e. prevented leaky gut; reduced the “clinical progression of colitis (disease activity index or DAI)”; reduced the “colon histological score” (or measure of disease activity in inflammatory bowel diseases) and reduced visceral hypersensitivity (or abdominal pain).

There were also favorable changes in inflammatory markers: “GABA inhibited the …increase in the proinflammatory cytokines tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-12 (IL-12), and increased the expression of the anti-inflammatory cytokine IL-10 in the colon tissue.”

Their conclusion is as follows: “These data suggest that increasing gastrointestinal levels of GABA may be useful for the treatment of colitis.”

My GABA visceral pain story

I have chronic SIBO (small intestinal bacterial overgrowth) and found that sublingual GABA helped when I would get that awful and painful belly bloat. When my SIBO was at its worst I would be in pain all night, tossing and turning and unable to sleep because of the belly distension/bloat.

It was often a combined approach of sublingual GABA, Iberogast and topical peppermint and lavender essential oil on my bloated belly.

More recently I found that the topical GABA called Somnium, rubbed onto my bloated belly, helped tremendously too. You can read more about Somnium here.

(My SIBO is much much better now, since I’ve been using berberine, but that is a topic for another blog post.)

GABA: stress, anxiety and visceral pain

As you know, I consider myself a GABA girl and it also helps ease my physical anxiety.

The above animal study doesn’t address the impacts of GABA on anxiety but there is research showing that “in concert with chronic visceral pain, there is a high comorbidity with stress-related psychiatric disorders including anxiety and depression.

Evidence suggests that long term stress facilitates pain perception and sensitizes pain pathways, leading to a feed-forward cycle promoting chronic visceral pain disorders such as irritable bowel syndrome (IBS).”

It makes total sense that GABA can play a role in addressing all of this for me – the visceral pain and IBS, the physical anxiety and sleep issues too.

GABA eases Gail’s painful gut spasms and reduces her stress

Neither myself or Gail have colitis and yet GABA helps us both with SIBO and the visceral pain we experience, and the associated anxiety. Gail shares this: “I’ve had diarrheal IBS for decades, recently diagnosed SIBO. Missed a lot of work with pain spasms and diarrhea almost every work morning. I had a phenomenal experience with my first dose of GABA at bedtime and like a miracle I’m pain-free in the morning.

It’s a huge huge improvement! (unless there’s a major stressor in my life like when my mom recently passed away)

I also take GABA at work if I anticipate a stressful situation. I love that I am still sharp mentally on this.”

A few GABA product options – a sublingual, a powder and a cream

Some of the GABA products I recommend include Source Naturals GABA Calm lozenges and Now GABA Powder. You can purchase these from my online store (Fullscript – only available to US customers – use this link to set up an account).

If you’re not in the US, Source Naturals GABA Calm lozenges and Now GABA Powder are available via iherb (use this link to save 5%).

As always, I use the symptoms questionnaire to figure out if low GABA or other neurotransmitter imbalances may be an issue for you.

Wrapping up and your feedback

I do always appreciate questions and feedback like this so keep your questions and comments coming. I do hope my sharing my experience with GABA for visceral pain and this other feedback has been helpful to you.

While this blog is specific to the research on GABA for colitis, I feel comfortable saying the use of GABA could also be considered for belly pain/visceral pain in someone with a diagnosis such as Crohn’s disease (which like colitis is also classed an IBD/inflammatory bowel disease) or IBS/SIBO (irritable bowel syndrome/small intestinal bacterial overgrowth).

How has GABA helped reduce your visceral pain? (please share if you have colitis or Crohn’s disease or IBS/SIBO or another digestive issue).

Has GABA also helped to reduce your physical anxiety, tension and self-medicating with sugar or alcohol in order to relax?

If yes, which products have helped, how much and do you find swallowed or capsule opened or powder is more effective for your needs?

If you’re a practitioner do you use GABA with your colitis clients/patients?

And please let me know if it’s helpful that I’m now including product recommendations and where to get them?

DLPA vs DPA for pain, food cravings, depression, grief, lack of joy; and impacts of DLPA on sleep, and feeling more stressed/anxious

April 5, 2024 By Trudy Scott Leave a Comment

A very common question I get is from folks asking about the difference between the amino acids DPA (d-phenylalanine) and DLPA (dl-phenylalanine) for endorphin support and endorphin/dopamine support. I dedicate an entire blog to this question explaining the differences and which one I use for weepiness, heart-ache, pain and energy. I also discuss where tyrosine (for dopamine support) fits in. If you missed that or need a recap you can read about this on the blog.

The blog post generated some great questions that I’m sharing today, with my feedback, in case you have similar questions. I discuss a question about DLPA vs DPA for pain and impacts on sleep; a question about DLPA (used by mistake) raising already high dopamine levels and why DPA isn’t working any more for food cravings; a question about using DPA with GABA; and a question about DPA for depression and lack of joy caused by grief.

Here is the question from Gloria who shared this feedback about her use of DLPA (as part of a pain relief product) but says she can’t use it past noon. She also wants to know more about DPA for pain relief:

My experience with DLPA is as part of a supplement called Curamin for pain relief from arthritis that also has curcumin and boswellia. It works quite well in the AM but I can’t tolerate it past noon or it negatively affects my sleep.

Interesting to learn it is similar to tyrosine which I have had sleep problems with in the past.

Does DPA work as well for pain? Is it best to take amino acids on an empty stomach for best absorption? Does that mean an hour before a meal or two hours after? Thank you for your blogs and book!

It’s great that this combination product offers pain relief and it’s good that she has made the connection to poor sleep when it’s used after noon. This is a popular product that I would like to see include the possible impacts on sleep and the other precautions for DLPA . It is a proprietary formulation so you don’t actually know how much DLPA you’re getting. I really don’t like not knowing.

One other concern is that curcumin is high-oxalate and for some this can make pain worse. Otherwise, curcumin and boswellia are excellent for pain relief and reducing inflammation.

DPA is more effective for pain than DLPA because it offers a bigger endorphin boost. If oxalates are not an issue, one option could be to continue with the Curamin before noon and if needed, add standalone DPA in the afternoon and evening, for added pain relief.

Amino acids are more effective on an empty stomach and even more effective when opened on to the tongue. I share more about opening DPA onto the tongue in this blog.

DLPA (used by mistake) raised already high dopamine levels and why isn’t DPA working any more for food cravings?

Rhonda shared how she found out the difference between DPA and DLPA the hard way and wants to go back to DPA:

I certainly found out the difference the hard way. I had used Lidtke Endorphigen for a few years and I think it helped a bit with food cravings. As I am in Australia, I depend on my sister’s visits from US for my supply. When I ran out last year, I bought DLPA by mistake.

After 1 week I was unable to cope with life, totally stressed out about everything, wanting to cry or scream or run away. Zero tolerance towards anyone. After 10 days I realized my mistake and I went back to normal in 24 hrs.

I believe DLPA resulted in very high dopamine as I already have a very slow COMT gene activity for breaking down dopamine.

I now take Endorphigen again but not seeing much effect on sugar cravings this time.

That is quite the reaction she experienced but I’m glad she figured it out so quickly. It’s not uncommon for some folks to react to DLPA like this, feeling more stressed and even anxious. High dopamine, and norepinephrine and epinephrine (so a huge adrenalin rush), related to slow COMT activity could well be the cause.

When Endorphigen (or any of the amino acids) work well initially we continue with trials of higher doses to find the ideal dose. It may also be that a reset is needed after the shift in dopamine.

Rhonda did say she thinks Endorphigen “helped a bit with food cravings.” When it only helps a bit it may be that the dose isn’t high enough or we may need to consider other neurotransmitter imbalances. They can all cause cravings for slightly different reasons: GABA/stress, serotonin/worry or low mood, glutamine/low blood sugar. More on that and the respective amino acids here.

Can GABA be used with DPA?

Ray asks: “Can I use GABA 25mg and also take DPA? Would either/or offset the other?”

My feedback: If someone has low GABA symptoms and GABA helps and they also have low endorphin symptoms and DPA helps then they are absolutely fine to use together and even at the same time. However, I have my clients trial one at a time in order to find the ideal dose and so you know how each one is working

What can I use for my depression and lack of joy, caused by grief?

Vee says she needs something “to get through my grief depression”:

Completely flat, no joy. I always had a calm flat disposition, but now it’s a complete zero. I need my brain to produce some oxytocin so I can like myself, my family and remember all I should be grateful for. I sleep good. I don’t take any meds, and I don’t abuse alcohol. Does tyrosine affect the brain in the way of producing oxytocin?

My feedback: I use DPA/Lidtke Endorphigen for this very purpose. It’s wonderful for grief, depression, lack of joy and the weepiness we see with low endorphins. It also helps with emotional eating that can show up as we try to self-medicate with treats in order to try and feel better.

When the depression also includes being flat, blah and curl-up in bed we use DLPA instead of DPA, or a combination of DPLA/DPA or tyrosine/DPA. Trials of each, one by one, helps you figure out what works best for your unique needs.

And for some folks GABA is helpful as shared by this woman who found GABA allowed her to sit with a feeling of peace and calm most of the time after her mum passed away.

Research does shows a link between dopamine and oxytocin, with oxytocin “emerging as one particular neural substrate that may be influenced by the altered dopamine levels.” Also, for oxytocin support I’d focus on hugs, massage, touch, laughter, making love, yoga, and petting a dog or cat.

DPA and DLPA product options

Products I recommend include Lidtke EndorphiGen (which is DPA) and Pure Encapsulations DL-Phenylalanine (DLPA). You can purchase these from my online store (Fullscript – only available to US customers – use this link to set up an account).

If you’re not in the US, these products are available via iherb: Doctor’s Best D-Phenylalanine (or DPA) and Life Extension D, L-Phenylalanine (or DLPA) (use this link to save 5%).

Additional resources when you are new to using DPA and DLPA, and other amino acids as supplements

As always, I use the symptoms questionnaire to figure out if low endorphins or low dopamine or other neurotransmitter imbalances may be an issue for you.

Wrapping up and your feedback

I do always appreciate questions and feedback like this so keep your questions coming. I do hope my sharing these ones have been helpful to you.

How has DPA or DLPA helped your pain, depression, lack of joy, weepiness, and grief? And has DLPA affected your sleep or made you feel more anxious or stressed?

If yes, which products have helped and do you find swallowed or capsule opened is more effective?

If you’re a practitioner do you use DPA and/or DLPA with clients/patients?

And please let me know if it’s helpful that I’m now including product recommendations and where to get them?

Ox bile as a supplement: to help counter the effects of dietary oxalates very likely caused by bile issues and poor fat digestion

March 15, 2024 By Trudy Scott 69 Comments

I’m using ox bile (as a supplement) to help counter the effects of dietary oxalates very likely caused by my bile issues and poor fat digestion.

I started with 125 mg ox bile with lunch and dinner and now I’m up to 250 mg at lunch and 375 mg at dinner. Many ox bile products are 500 mg but I decided to start low and go slow and also use an ox bile only product rather than ox bile combined with digestive enzymes.

I don’t know exactly what my liver or gallbladder issues are but suspect low bile production and/or sluggish bile flow.

I have an issue with dietary oxalates and using ox bile confirms my suspicions because I can feel it helping further with symptom reduction (foot and eye pain, and restless legs at night). Because of improved fat digestion, I’m encouraged it’s going to help with longer term bone health (I was recently diagnosed with osteoporosis), immunity, hormone balance and heart health too. I expect better absorption of healthy fats like omega-3 fatty acids, evening primrose oil and fat-soluble vitamins A, E, D and K (and D and K are so important for bone health).

Of course, all this means less oxalate absorption and a reduced impact of the sharp damaging crystals found in medium/high oxalate foods. Oxalates also bind to minerals like zinc, magnesium, and calcium so those mineral deficiencies should shift too.

Read on for a background on oxalate crystal disease, the research on conjugated bile acid replacement therapy (or ox bile supplementation) and oxalate/fat digestion mechanisms, and more about signs of bile issues and solutions. I also share what else I do to mitigate oxalate issues and improve fat digestion, and the ox bile product I am using.

Ox bile increases fat absorption and reduces oxalate absorption

This paper, Conjugated bile acid replacement therapy reduces urinary oxalate excretion in short bowel syndrome, explains that “Soluble oxalate is hyper absorbed by the colon leading to hyperoxaluria and an increased risk for renal calcium oxalate stones and deposits” (and other pain issues – more on that below).

Using ox bile as a supplement (or replacement) with meals “increases fat absorption and thereby decreases calcium fatty acid soap formation and oxalate hyperabsorption.” What does this mean? When fat absorption is improved with ox bile supplements there is more calcium left to bind to excess oxalates in the gut and get rid of them in the stool i.e. less oxalates are absorbed.

I encourage you to read the above paper for a better understanding of the mechanisms.

I do appreciate this team of researchers who have highlighted this approach to help with oxalate issues. Keep in mind I’m experimenting and extrapolating from this single case study of someone with short bowel syndrome and based on what I already know about bile/fat digestion, my own oxalate issues and symptoms of poor bile production/flow (see below).

I don’t have short bowel syndrome but there are a few related studies like this one from the same department, so I feel comfortable experimenting and tracking.

Other pain issues and my pain symptoms caused by dietary oxalates

Keep in mind that the increased absorption of oxalates also causes issues like joint and soft tissue pain, anxiety, restless legs, insomnia, bladder issues, vulvodynia, eye-poking (in autism), thyroid problems, osteoporosis, damage to the heart etc. even when there are no kidney stones. This is not recognized in kidney stone research but is seen extensively in clinical practice.

In 2012 I made the connection between oxalate intake and my excruciating foot pain – a combination of hot-burning-coals-pain and shards-of-glass-pain. The pain has always been worse at night and at its worst I was unable to sleep with severe restless legs. A few years later, I noticed my left eye being affected too, with scratchy discomfort and mild pain. There is also a goopy kind of discharge from the inner part of my eye and burning/redness crystal-like teariness on the outer parts of my eyes.

You can read more about my oxalate story and oxalate crystal disease on this blog – Oxalate crystal disease, dietary oxalates and pain: the research & questions.

It’s more than only ox bile replacement to help with oxalate issues

I say that ox bile helps further because this is a journey I’m on and there are many nutritional approaches that have been helping me over the years. My symptoms have reduced as I do eat mostly low oxalate with some medium oxalate vegetables from time to time, and occasional chocolate or carob (which are high oxalate).

I continue to finesse my use of calcium citrate at bedtime when my symptoms do flare. I am fortunate that I am able to eat cheese so this is another source of calcium for me.

I have pyroluria so I have long used vitamin B6 which is recognized to be helpful for some with oxalate issues. I suspect this may have prevented dumping when I first switched to low oxalate eating.

Signs of low quality bile from Anne Louse Gittleman

These are from her book, The New Fat Flush Plan:

Queasiness after a fatty meal (impaired bile flow)
Light-colored or floating stools (lack of bile output)
Nausea/motion sickness (not enough bile)
Dry skin and hair (lack of essential fatty acids)
Constipation (inadequate bile for lubrication)
Constant feeling of fullness
Inability to lose weight
Pain under the right rib cage (reflective pain from the gallbladder)
Hemorrhoids (congested liver)
Varicose veins (pressure from constipation due to thickened bile)
Pain between the shoulder blades (reflective pain from the gallbladder)
Bloating or gas
Headache over the eyes (gallbladder meridian passes over this region)
Bitter taste in the mouth after meals (sign of bile regurgitation)
History of prescription or recreational drug use (need for more liver and gallbladder support)
Sensitivities to chemicals
Easily intoxicated (need for more liver and gallbladder support)
Fibromyalgia (sign of liver and gallbladder overload)
Hypothyroidism (sign of deficient bile to stimulate active thyroid hormone in fat cells)

I’m adding these signs/related issues/conditions:

Fatigue
Itchy skin
SIBO/small intestinal bacterial overgrowth
Osteoporosis
History of gallbladder attacks or gallstones
Oxalate issues

In my Anxiety Summit interview with Anne Louise Gittleman she explains what bile is and why it’s so important (read here if you’re new to this).

What I’ve already done to improve my bile production/quality

Here is a quick summary of the advice Anne Louise Gittleman offers, with a note of what I’ve done. I share this to illustrate that I didn’t jump straight to ox bile supplementation/replacement:

Elimination of food allergies (I’ve done this)
Addressing low levels of hydrochloric acid or stomach acid (this is not an issue for me)
Controlling stress (this is ongoing)
Adding bitter greens to the diet (I do this as much as I can, avoiding medium/high oxalate bitter greens)
Hot lemon water in the morning (a favorite of the original Fat Flush Plan and something I’ve done for years)
Adding non-GMO lecithin from soy and sunflowers to your morning smoothie (I don’t do this)
Using a bile building formula that contains choline, taurine, beet root, inositol and methionine, and pancreatic lipase (I use taurine but can’t use beet root because it’s high oxalate; I did a 2 month trial of a lipase only supplement with no changes; I will likely experiment with choline, methionine and inositol in the near future)
Using castor oil packs (I plan to do this in the near future)

These are some of the other approaches that can also help:

Digestive bitters (it does help me and I continue to use it but it’s not enough)
Toxin removal (I’ve experienced the harmful effects of acute environmental toxin exposure and my daily use of taurine helped. I blogged about this here.)
Ongoing detox with infrared sauna (I use a Therasage portable sauna)
Ox bile supplementation/replacement (I chose to use ox bile to be sure it was a bile issue I was dealing with and I did many other interventions first.)

My observations when using ox bile supplementation

I have not had any severe pain flares and have not needed to use extra calcium citrate in the night. The other profound change was a dramatic increase in energy. A few months ago I thought my Lyme was flaring again as I was so exhausted in the afternoons. This exhaustion has dissipated.

In terms of digestive symptoms, I notice less queasiness after a fatty meal like roast chicken with the skin on or a fatty lamb slow cooker stew. The constant feeling of fullness, gas and bloating has improved too. I suspect ox bile is helping with SIBO because it’s antimicrobial. But I can’t be sure since I started berberine 6 months ago and noticed it reduced methane gas production.

I have yet to test out motion sickness on a boat trip but I haven’t been using wristbands in the car and have been fine. I had been having some unusual/new skin itchiness a few months ago and this has now resolved. I do have sensitivities to chemicals but I haven’t noticed any change yet.

I used my stool color as a gauge to whether the ox bile was working – as I increased the dose I noticed it got darker and I have no more floaters. My bowel movements are much easier (more lubrication) and I feel the urge to go more than before.

It will be interesting to see if longer term this helps with improving my bone density. It makes no sense that I have osteoporosis given I’ve been physically active all my life. I highly suspect my bile issues have been a factor since childhood and then got worse during perimenopause Research shows “Gallbladder emptying time is longer during the perimenopausal period.” Unfortunately kidney stones and oxalate issues ramp up in menopause so it’s the perfect storm. I will be discussing all this with my endocrinologist/bone density doctor and ideally do some testing to figure out what the bile issues are (the pancreatic elastase test was fine).

I do track carefully and only make one change at a time so I typically know what improvements I can attribute to what changes.

Ox bile product options

Allergy Research has an Ox Bile 125 mg product and a 500 mg product. You can purchase these from my online store (Fullscript – only available to US customers – use this link to set up an account).

If you’re not in the US, Nutricology has an Ox Bile 125 mg product and a 500 mg product. This is the brand I happen to be using. It can be purchased on iherb (use this link to save 5%).

In conclusion

I’d like to give a shout out to my colleagues… I first learned about oxalates from my dear friend Julie Matthews. Hearing her present at a conference helped me make the connection to my feet pain issues. She introduced me to Susan Owens, oxalate guru and researcher, and the TLO/Trying Low Oxalate group, and now I communicate regularly with them, the TLO moderators and members. And I met Sally K. Norton a few years ago. She is the author of this excellent book, Toxic Superfoods: How Oxalate Overload Is Making You Sick (my Amazon link).

Unfortunately no-one discusses the use of ox bile replacement/supplementation for those of us with oxalate issues and bile issues, and I suspect it’s an under-appreciated tool for those of us who continue to struggle. Hopefully this research and my results starts a discussion on the topic and further interest.

Sally K. Norton does mention a connection in her book: “The immune system has a method for shielding surrounding tissues from oxalate crystals; entrapping them with extruded DNA called a neutrophil extracellular trap (NET). These NETs forming around oxalates may contribute to gallstones and gallbladder “sludge”. If this is the case in my situation, then my lifelong issues with bile were likely made worse by my intake of medium- and high-oxalate foods.

I do hope that me sharing my personal experiments and healing journey helps you or someone you know. Honestly, I could write a book on oxalates and what I’ve learned over the last few years. There is so much to all this and even though it’s a “pain” to be affected like this it is fascinating. I do feel thankful to have dietary and nutritional “solutions.”

The next step for me is looking into and addressing my endogenous oxalate production i.e. oxalates that are produced internally vs oxalates that are ingested. Stay tuned for an update on this.

Do you have oxalate issues together with gallbladder/bile issues/fat digestion issues and how has ox bile supplementation helped you?

Has ox bile helped you with low bile production or sluggish bile – even if you don’t have oxalate issues?

If you’re a practitioner have you used ox bile with your clients or patients?

D-phenylalanine (DPA) for easing both physical pain (tooth pain) and emotional pain over the holidays

January 5, 2024 By Trudy Scott 33 Comments

Today I share how the amino acid D-phenylalanine (DPA), used as a supplement multiple times a day, and opened on to my tongue, eased both the physical tooth pain I experienced for 14 days and the emotional pain I was feeling over the holidays.

In this blog I share more about DPA and endorphins when it comes to pain – both physical and emotional. I also share two DPA products I recommend, product label confusion and more about how DPA differs from DLPA (DL-phenylalanine). I am often asked this question and even long time users of DLPA are sometimes surprised to learn how different DPA is. As always, I like to share some research and other related blogs on the topic. Here is my recent and very positive personal experience with DPA, a firm favorite of mine:

I’m just back from the dentist – my crown was re-cemented and I’m a happy camper now. It popped off just before Christmas and I had to wait until now! There was a tiny cavity beneath the crown which is why I was having daily pain.

Thank goodness I always have DPA (the amino acid d-phenylananine) on hand. I gravitate to it for pain relief – sports injuries like muscle sprains, the rare headache and this time for tooth/jaw pain.

I opened a DPA onto my tongue as soon as I could feel the dull ache start and the pain relief lasted a few hours. It works by boosting endorphins to provide pain relief – kind of like acupuncture. I call it “powdered acupuncture”.

Some days I used 3-4 and one day I needed 6. Taking one before bed was wonderful.

I also got bonus benefits for emotional well-being over the holidays. It’s the first Christmas without my darling mom and I really needed the endorphin boost to help with the emotional pain.

The DPA product I used was Doctor’s best (details below) and I opened up the 500 mg capsule onto my tongue each time I needed pain relief.

The number of capsules I needed seemed to vary by how much chewing I was doing (for example, I had more pain after a steak meal vs smoked salmon) and what I was eating or drinking (for example, I had more pain after drinking something cold). I simply used a DPA capsule when the dull pain started, making sure it was away from protein (not always but most of the time).

UPDATE: Sept 13, 2024
DPA has come to my rescue yet again and this time the tooth pain has been very severe. I initially suspected it was the crown again but when I got into the dentist an xray confirmed an abscess at the tip of one of the roots.

It’s a first for me and I’ve never experienced a toothache like this. The pain ramps up from zero to 10 (with 10 being most severe) in a matter of seconds. The only thing that helps right now is DPA. I’m opening a capsule every few hours and have even had to use it every 30 mins when it’s really severe like after drinking or eating something. It brings to pain down to a 3 in a matter of minutes.

I’ve figured out that using a straw to drink liquids helps a ton. I’m also using a soft ice-pack a few times a day too. Strangely it’s worse just before bed, after I take my bedtime supplements. I need the DPA and ice-pack but fortunately I have no pain through the night. Thank goodness for that!

I’m also using a herbal antibiotic and herbal mouth swish from my naturopath while I get a second opinion, learn about my options, and decide next steps.

All this has solidified DPA as my go-to supplement for pain relief.

One of the DPA products I recommend: Doctor’s Best D-Phenylalanine

There are not many d-phenylalanine/DPA products available but of those I have two that I recommend: Doctor’s Best D-Phenylalanine and Lidtke Endorphigen. Both contain 500 mg DPA but the labels can be confusing at first – at least until you’re familiar with them.

Also, this amino acid, DPA, is not to be confused with docosapentaenoic acid (also abbreviated as DPA), an omega-3 fatty acid similar to eicosapentaenoic acid (EPA).

Here is the Doctor’s Best D-Phenylalanine description:

Doctor’s Best D-phenylalanine is a non-protein amino acid that acts as an inhibiting agent to enzymes that degrade enkephalins, naturally occurring peptides in the body that metabolize endorphins. Endorphins are neurotransmitters that play a key role in the function of the nervous system and are associated with feelings of pleasure. By limiting production of enzymes that break down endorphins, the supplement can help support a healthy mood and normal functioning of the nervous system.

Helps support healthy mood
Helps support endorphin metabolism
Help support neurotransmitter function

This is the actual product that I used over the past 2 weeks and have used it on and off as needed for a few years. It was one of the nutrients that helped when I sprained my ankle when visiting my brother in Las Vegas. More here

As you can see there is no mention of pain on the label or product description. I share more on the pain/endorphin connection below.

You can purchase this online from their website or from iherb. If you use my iherb link you’ll save 5%. This is a good option if you’re not in the USA and already use iherb for one-stop shopping of quality products.

The other DPA product I recommend: Lidtke Endorphigen

The other product I recommend is Lidtke Endorphigen which also contains 500 mg DPA and a small amount of vitamin B6 and riboflavin (vitamin B2). As you can see, this product does mention pain but not the emotional support/mood benefits on the front label.

Here is the Lidtke Endorphigen description

Ease Minor Pain & Feel Good with Healthy Endorphin Level Maintenance

Endorphins are nature’s way to relieve common minor pain and promote a cheerful mood. Research shows that endorphins are released in response to pain and stress, bringing relief. The second wind and runner’s high during and after a vigorous run are results of endorphins. Acting as an analgesic and sedative, endorphins diminish our perception of pain…. But there is more.

Recovery centers report that endorphins promote recovery from a wide variety of unhealthy cravings.

Low endorphin symptoms and typical dosing of DPA

I use the symptoms questionnaire to help clients identify if they have low endorphin symptoms (you can see that here).

Typical dosing is 500 mg to 1000 mg DPA 3-4 x day between meals/away from protein. I do find having clients open the capsule onto their tongue to be more effective for quick pain relief – with results as quickly as 5-10 minutes.

DPA vs DLPA: they are quite different but have some overlaps

I am often asked if DPA and DLPA are the same – they are quite different but have some overlaps as outlined in this blog post on the topic: What is the difference between DPA and DLPA (amino acids) and which one do I use for weepiness, heart-ache, pain and energy?

The precautions are also not the same so I always review contraindications with all my clients and encourage you to do the same.

DPA for MS pain, weepiness, emotional pain and more

Here are a few blog posts illustrating the use of DPA in multiple sclerosis, weepiness, physical pain, emotional pain and resilience, cravings/emotional eating and even helping to wean off prescription pain medication:

Multiple sclerosis: low endorphin research and the amino acid DPA (d-phenylalanine) for pain, depression, comfort and trauma support “The endogenous opioid system is …well known to play a role in the development of chronic pain and negative affect [i.e. depression], both of which are common comorbidities in MS.”
DPA for weepiness, pain and comfort and reward eating
The individual amino acids glutamine, GABA, tryptophan (or 5-HTP), DPA and tyrosine are powerful for eliminating sugar cravings, often within 5 minutes
When using the amino acid DPA (d-phenylalanine) I have more resilience and more buffer in the caregiving work I do, and just the oops’s of life As I mentioned above, using DPA over these holidays also gave me more resilience and the endorphin boost I needed help with the emotional pain of losing my mom.
Wean off prescription pain medication, improve sleep and reduce emotional eating with DPA (an endorphin-boosting amino acid)

Be sure to use the search feature on the blog to find additional applications of DPA.

DPA research on pain and depression

The use of DPA is not new as you can read in this paper from 1982 – D-phenylalanine and other enkephalinase inhibitors as pharmacological agents: implications for some important therapeutic application

A number of compounds have been shown to inhibit the degradation of enkephalins. As expected, these compounds produce naloxone reversible analgesia and potentiate the analgesia produced by enkephalins and by acupuncture.

One of these, D-phenylalanine, is also anti-inflammatory.

D-phenylalanine has proven to be beneficial in many human patients with chronic, intractable pain. It is proposed the enkephalinase inhibitors may be effective in a number of human “endorphin deficiency diseases” such as depression, schizophrenia, convulsive disorders and arthritis.

Additional resources when you are new to using DPA and the other amino acids as supplements

We use the symptoms questionnaire to figure out if low endorphins or other neurotransmitter imbalances may be an issue for you.

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control, sugar cravings, anxiety and mood issues.

The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs. You can find them all – including the Lidtke Endorphigen 500 mg that I mentioned above.

Also mentioned above is Doctor’s Best D-Phenylalanine which can be purchased on iherb.

Have you had success using DPA for toothache, dental abscess or your other pain issues – what kind of pain has it helped and how much has helped you?

Has DPA also helped with emotional pain and weepiness? And cravings/emotional eating?

If you’re a practitioner do you have success using DPA with your clients/patients?

Irukandji syndrome: severe pain, nausea, breathing difficulties and a feeling of impending doom (impact on serotonin and other neurotransmitters?)

December 30, 2022 By Trudy Scott 14 Comments

Irukandji syndrome is in the news again. In addition to the jellyfish sting causing severe pain, nausea and breathing difficulties, the research states there is a feeling of impending doom after you’re stung. I’m sharing this current news from Australia and a recent study because I’m curious about the mechanisms and short- and long-term impacts on serotonin and other neurotransmitters, likely affecting anxiety, depression, pain and insomnia. And I’d like to help create awareness since there is not 100% consensus on what to do right away after a sting and less awareness in the medical community than I feel comfortable with.

From the ABC article published this week in Australia: “Another child has been flown to Hervey Bay Hospital with a suspected Irukandji sting after swimming in a creek off Wathumba Road on K’gari (Fraser Island) in Queensland, Australia on Wednesday afternoon.

The key points of the article:

“Three young girls and a boy have been flown to hospital with suspected Irukandji stings in the past two days
The jellyfish stings can cause severe pain, nausea and breathing difficulties
A Toxicologist is calling for more research into their movements and physiology”

The yahoo news article expanded on the symptoms: “They have this severe body pain, often low back pain, nausea, vomiting, and this feeling of impending doom that sort of lays over the top of this whole thing.”

I found the latter interesting as impending doom is a classic sign of low serotonin. So I went digging into the research. I was enlightened and surprised by what I found.

Raising awareness on this worldwide increasing threat

This 2022 paper, Raising Awareness on the Clinical and Forensic Aspects of Jellyfish Stings: A Worldwide Increasing Threat is eye-opening and concerning and also mentions the impending doom symptom.

Irukandji syndrome is a severe illness produced by the envenomation i.e. injection of venom, of some species of small jellyfish from the Cubozoa class, known as box jellyfish.

It consists of a clinical picture dominated by systemic symptoms similar to a catecholamine surge, including hypertension, tachycardia, intense pain, and muscle cramping, eventually leading to pulmonary edema, shock and cerebral hemorrhage.

Also listed are symptoms of anxiety, restlessness, headache, localized sweating and impending doom. A feeling of impending doom is a classic symptom of low serotonin.

With regards to Irukandji syndrome it’s becoming a worldwide problem: “The first cases described happened in the northern Australian territories. However, similar disorders have been observed all over the tropical waters, including Thailand, the Caribbean, Florida, and Hawaii.”

The good news is that the authors state “Irukandji syndrome is typically not deadly, especially if supportive care is given early” and “not all encounters with species capable of producing Irukandji syndrome result in this clinical state.” They also share that typically the severe pain only lasts a few hours but do mention one case where “pain recurred up to a year later.” I discuss possible longer term effects below.

As you read the paper, be aware there are many types of jellyfish with many different mechanisms. Cubozoa includes the deadliest jellyfish species and includes Carukia barnesi and Chironex fleckeri. (commonly known as the Australian box jelly). It’s the Carukia barnesi that causes Irukandji syndrome.

The images in the above paper are graphic so be warned.

There is not 100% consensus on what to do right away

What is also really concerning is that there is not 100% consensus on what to do right away. This 2017 paper, Cubozoan Sting-Site Seawater Rinse, Scraping, and Ice Can Increase Venom Load: Upending Current First Aid Recommendations, published by Hawaiian researchers, found the “best outcomes occurred with the use of venom-inhibiting technologies (Sting No More® products)” and they state not to use a sea water rinse. They also found vinegar and heat treatment were less effective with certain types of jellyfish.

And yet the tentative recommendation from the above 2022 paper is to use vinegar, heat, sea water, and careful removal of remaining tentacles with tweezers quickly because only “about 1% of nematocysts (stinging cells) discharge upon initial contact.” They do suggest using Sting No More® before removing tentacles in order to deactivate the nematocysts.

I’m not sharing any of the above as conclusive in all situations but more to illustrate what both papers state: further research is needed in different places of the world, as different jellyfish species seem to react differently to the treatments.

There is also less awareness in the medical community than I feel comfortable with hence my desire to share this so you are more aware if you or a family member is stung by a jellyfish.

Are there possible long-term impacts on anxiety, depression, pain and insomnia? (and the potential role of amino acids)

Just like we have long-term impacts on anxiety, depression, pain and insomnia with Lyme disease and other infections like Bartonella – due to effects on serotonin, GABA and other neurotransmitters – do we need to consider these long term impacts after a jellyfish sting too?

I have to wonder if there are also longer term impacts given the trauma of the situation and the many medications that are needed to save your life: nitroglycerin, opioids, benzodiazepines and others.

If mood, anxiety, pain and sleep issues persist after the acute recovery phase (which can take up to 3 months and more) and there are other signs of low serotonin, GABA, dopamine and endorphins, it’s important to consider the use of targeted amino acids. I recommend tryptophan or 5-HTP for low serotonin symptoms (worry type of anxiety, insomnia and low mood), GABA for low GABA symptoms (physical anxiety and tension), tyrosine for low dopamine symptoms (depressed with low energy and poor focus) and DPA for low endorphin symptoms (pain and weepiness).

It would be wonderful to see research in this area.

Is there a possible role for GABA right after the sting too?

Given there is “hypertension, tachycardia, intense pain, and muscle cramping”, would the amino acid GABA help?

With Irukandji syndrome, “there have been reports of blood pressures as high as 300/180 mmHg” (normal is 120/80 mmHg). In one study, 80mg GABA was found to reduce mild hypertension and it’s possible that a higher dose of GABA may help right after the sting. It may also help to alleviate pain and muscle tension/muscle cramping too.

It would be wonderful to see research on GABA use right after the sting too.

Resources if you are new to using amino acids as supplements

If you are new to using GABA or any of the other amino acids as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the symptoms of neurotransmitter imbalances, including low GABA and low serotonin).

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control, sugar cravings, self-medicating with alcohol and more.

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms). This is a paid online/virtual group program where you get my guidance and community support.

I do hope these 4 young Australian children are doing well after having been stung.

Have you or a family member been stung by a jellyfish? Where did it happen and what type of jellyfish? What symptoms did you experience? What was the treatment and what was recovery like?

Have you or your family member had any long-term lingering symptoms of anxiety, depression, pain and insomnia? Have the amino acids or other solutions helped?

If you’re a practitioner have you seen long-term lingering symptoms of anxiety, depression, pain and insomnia in your clients/patients who have had a jellyfish sting?
