How to accurately measure a small amount of powdered GABA and other GABA options when GABA Calm is not tolerated

April 26, 2024 By Trudy Scott 18 Comments

Brenda finds one GABA Calm helps her sleep but more than one affects her sleep and she suspects the sugar alcohols in the product. She’d like advice on using an alternative and how to accurately measure a small amount of powdered GABA. Here is her question in her own words:

I have been on the FODMAP diet for a while and it is helping but I just realized that when I take GABA Calm I am ingesting sorbitol and mannitol. I take a bit more than one of those tablets each night to help me sleep and am very aware that if I take too much it can keep me awake.

Now that I have realized about the sorbitol and mannitol, I am looking for an alternative source of GABA. I see that you are now recommending the Now GABA Pure Powder product. I was about to purchase this to avoid the sorbitol and mannitol but then realized that I would have to take 1/16th teaspoon of the powder to equate to 150mg. I can’t see me ever getting that measurement correct.

So my question is, can you recommend another source of GABA that would enable me to take 150mg plus a little bit with a fair degree of accuracy and without those added FODMAPs? Thank you very much. I am very grateful for your work.

Brenda has likely been diagnosed with SIBO (small intestinal bacterial overgrowth) or IBS (irritable bowel syndrome) even though she doesn’t mention it. In some folks with SIBO or IBS, sugar alcohols such as xylitol, sorbitol and mannitol can cause digestive upset. Not everyone with SIBO or IBS has issues with GABA Calm. In fact, it’s typically very well tolerated and GABA Calm is a product I have been recommending for many years. However, some folks do have issues and it’s wise to look for an alternative and not push through.

In this blog I share more about sugar alcohols, how to accurately measure out 1/16 teaspoon of the GABA powder to equate to close to 150 mg, how I use my mini measuring spoon, a GABA/theanine product that is low dose and can be opened, and another option she could consider.

Sugar alcohols in GABA Calm and other GABA chewable products

Many of the chewable or sublingual forms of GABA, including GABA Calm contain sugar alcohols which can be problematic and cause digestive upset and often explosive diarrhea. The digestive upset alone could impact sleep.

Sugar alcohols include xylitol, sorbitol, mannitol and erythritol. Your reaction will depend on the amount of sugar alcohols used, how many chewable/sublingual tablets you use and how accustomed you are to sugar alcohols. You may get used to them and eventually be fine with consuming small amounts and yet for others the tiniest amount is an issue.

I share more about sugar alcohols on this blog: Why does chewable GABA make me run to the bathroom and what GABA do I use instead?

Using a mini measuring spoon set and GABA powder

It’s wonderful that GABA Calm is helping Brenda with her sleep issues and when we start to get benefits we do want to increase the amount to see if we can get further benefits.

She has a few options and one is to use the NOW GABA powder (or another GABA powder) with a mini measuring spoon set like this one (my Amazon link). This is mine and it is very easy to use, convenient and accurate.

As you can see it comes in various sizes: 1/4 teaspoon, 1/8 teaspoon, 1/16 teaspoon, 1/32 teaspoon and 1/64 teaspoon.

It is important to look at the product and work out how much you need to measure out. For example, the NOW GABA powder states 1/4 teaspoon is equivalent to 500 mg GABA. This means 1/16 is equivalent to 125 mg GABA. So if Barbara wants to take 150 mg she would use a little more than what would be in the 1/16 spoon (maths is coming in handy after all!)

Keep in mind that product equivalents do differ. For example tryptophan is typically lighter and fluffier than GABA. My tryptophan states 1 teaspoon is 1000 mg tryptophan so a typical starting dose of 500 mg tryptophan would be 2 x 1/4 teaspoon since each 1/4 is 250mg.

I love my mini measuring spoon and use mine on a daily basis for theanine in the day, calcium citrate after dinner (for my oxalate issues), and for GABA and tryptophan at bed time.

Combined GABA and theanine: GABA-T SAP as one option

Another option is using a lower mg GABA/theanine product and opening it. Nutritional Fundamentals for Health GABA-T SAP is another favorite of mine. This product is pleasant-tasting when opened on to the tongue and works very well when GABA Calm can’t be used. It contains 300 mg GABA and 150 mg theanine, so can easily be halved to provide the 150 mg GABA she is looking for.

Research shows that the combination of GABA and theanine may improve sleep: GABA and l-theanine mixture decreases sleep latency and improves NREM sleep. The authors share the sleep and anxiety benefits of both GABA and theanine:

γ-Aminobutyric acid (GABA) is the main inhibitory neurotransmitter and it is well established that activation of GABAA receptors favours sleep.

l-Theanine, a naturally occurring amino acid first discovered in green tea, is a well-known anti-anxiety supplement with proven relaxation benefits.

But Barabra is going to have to do a trial to see if this combination works for her.

Mixing and matching as an other option

And finally, if she was also taking GABA Calm in the day for stress and overwhelm, she could do a trial of using this during the day (for the convenience factor) and then at night use the GABA powder or opened GABA/theanine capsule (because it’s a bit more finicky). This way she’s consuming less sugar alcohols overall.

Both GABA products, the mini measuring spoon set and where to find them

Today I mentioned the Now GABA Powder and NFH GABA-T SAP. 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, the Now GABA Powder and Nutricology ZenMind (a GABA/theanine combination comparable to GABA-T SAP) is available via iherb (use this link to save 5%).

And the mini measuring spoon set can be found here (my Amazon link)

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

As a reminder, low GABA can cause physical tension, anxious feelings, feelings of panic and problems sleeping, as well as self–medicating with alcohol or carbs to relax or fit in. As always, I use the symptoms questionnaire to figure out if low GABA 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 GABA 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 questions like this so keep them coming so I can share and educate further.

Now I’d love to hear from you – do you have issues with the sugar alcohols in GABA Calm or another chewable GABA product? (if yes which one?)

Did you move to a GABA powder and do you use a min spoon set? Or does another GABA product work for you?

Please share how GABA helps and how much helps you?

If you’re a practitioner do you use GABA powder and mini spoons with your clients/patients?

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

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.

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%).

Somnium GABA Cream is available with international shipping. Click here to get Somnium GABA Cream (and use my coupon code TRUDY15 to save 15%).

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?

Collagen causes anxiety and sleep problems for some people. I would never have connected the dots but apparently I am one of those people.

March 1, 2024 By Trudy Scott 13 Comments

Thank you for solving my sleeping problem! I would never have connected the dots regarding collagen causing anxiety and sleep problems for some people, but apparently I am one of those people.

Although I would fall asleep instantly at bedtime, I would wake up 3 or 4 hours later and while my body was tired, my mind was wide awake and I was unable to go back to sleep for at least 2 or 3 hours. I would think about all the things I needed to do and the challenges I was having. These things would not bother me as much in the day. No matter what I tried – like praying and listening to calming music, I could not shut off my anxious thoughts.

Then it occurred to me that when I go out of town to visit my family, I sleep better. After hearing Trudy’s collagen presentation on the Osteoporosis Summit, I connected the dots! For the last 6 months, I have been putting about 10 grams of Vital Protein collagen in my coffee each morning. I don’t take the collagen with me when I travel. So I stopped using it and lo and behold, I am sleeping the best sleep I have slept in a long time! I even look forward to going to sleep.

So I thank you Trudy from the bottom of my heart for enlightening me. And Margie, I thank you for the wonderful Summit you put together with so much great information. I would still be sleep deprived if it wasn’t for you both!

I was so pleased to receive this lovely thank you email from Merrilyn (sent to me and summit host Margie Bissinger) and said how happy I am for her. I asked if I could share her feedback as a new blog so we can enlighten others who may have similar issues and because it’s an opportunity to share some of sleep/collagen research that supports a possible mechanism. She kindly said yes and answered my questions:

How long had you been using collagen and how long after starting it did the sleep issues start?
And how quickly after stopping the collagen did your sleep improve?
Did you consider using tryptophan or 5-HTP so you could continue to use the collagen? And are you prone to low serotonin?

Read on for some background on the serotonin-lowering effects for some folks who consume collagen, Merrilyn’s responses to my questions, my insights, some of the research, and the tryptophan and 5-HTP products I recommend.

The original collagen/gelatin serotonin-lowering blog/research from 2017

I first addressed this potential cause for anxiety, mood and sleep issues in a blog in 2017 – Collagen and gelatin lower serotonin: does this increase your anxiety and depression?

Margie invited me to share this information and some of the research with those who are using it or planning to use it for osteoporosis. I’m so glad I accepted because clearly there are still folks who are not aware of the potential serotonin-lowering effects of collagen. And I’m sharing Merrilyn’s results via this new blog in case it’s also new to you.

Briefly, collagen and gelatin are used in tryptophan-depletion studies to lower serotonin levels. It does this because neither collagen or gelatin contain tryptophan. Some people seem to be adversely impacted by acute tryptophan depletion/ATD caused by collagen or gelatin consumption while others are not.

If this is all new to you, I encourage you to read the original blog and search for “collagen” to find other information on this topic on my site.

How long had you been using collagen and how long after starting it did the sleep issues start?

I asked how long she’d been using collagen and how long after starting it did she notice problems with her sleep. This wasn’t clear to her and many folks like Marrilyn unfortunately don’t connect the dots right away.

I started Vital Proteins collagen on July 1, 2023. I did mark that down because as I add supplements to my diet, I try to make notes and only do one at a time in case they cause a problem. I did note that I was not consistent with taking it daily and I was only taking 5 to 10 grams daily ( in my cup of coffee!).

I have always had a bit of a problem with waking up at night, but normally go right back to sleep. I can’t remember exactly when the sleeping problems worsened and I never connected them to collagen.

Seems like over time, the sleeping and waking up with ruminating thoughts was getting worse. I had started trying Tylenol PM or Advil PM, only taking 1/2 of one with one plain Tylenol or Advil to help me sleep and relieve any muscle tension from exercise. That did not always help. Taking a whole PM was better, but I felt groggy the next day. I don’t need any now that I have stopped the collagen.

How quickly after stopping the collagen did your sleep improve?

When the cause of waking in the night is due to low serotonin, it’s common to notice improvements very quickly after stopping collagen. This was the case with Merrilyn:

I would say my sleep improved immediately after stopping it. I realized that on the days I was out of town and didn’t take the collagen, I slept better. … but I attributed it to the fact that it is cooler there and my 6 year old grandson wears me out by the evening. I do not take the collagen with me and I had not connected this to the sleep pattern.

I returned home after one trip and started the collagen that next morning and the sleepless nights started again. I can’t remember when I listened to your talk, but I am guessing around January 18th, because I noted that I stopped after that day and according to my Fitbit and my memory, I slept great the night of January 19th and other than one night, I have slept well since.

I do want to commend Merrilyn for keeping a log of new supplements and sleep patterns. It’s something I recommend for all my clients.

Did you consider using tryptophan or 5-HTP so you could continue to use the collagen and are you prone to low serotonin?

I also asked if she considered using tryptophan or 5-HTP (some folks do better on one vs the other) so she could continue to use the collagen – she had not considered this. And I wanted to know if she has been prone to low serotonin or suspects low serotonin currently.

I do believe I am prone to low serotonin based on the little I have read in your book. I have thought about using tryptophan with the collagen and might later. For now, I just want to enjoy sleeping and focus on improving my diet.

I also have evenings when I crave sugar. I can do without it during the day, but evenings are worse. Something else to work on.

She’s referring to the low serotonin symptoms questionnaire in the amino acid chapter of my book, The Antianxiety Food Solution. It’s also on the blog here.

A big clue is the insomnia and anxiety caused by consumption of collagen, and also the evening cravings. There are cravings with all the neurotransmitter imbalances, with afternoon/evening cravings common with low serotonin.

It is possible Merrilyn’s anxiety and insomnia effects are for reasons other than low serotonin: glutamate, oxalate, arginine or a histamine reaction are all possible with collagen intake). Doing a trial of tryptophan or 5-HTP while consuming collagen would confirm a serotonin connection.

Osteoporosis, allergies, serotonin and coffee

Merrilyn also shared that she is in her early 70s and besides osteoporosis and allergies, is generally healthy and takes no prescription drugs. Interestingly, research finds there may be a role for 5-HTP (and presumably tryptophan) for allergies and asthma, so this may be another clue for her.

Of course, reducing her cravings – tryptophan and/or 5-HTP make it easy – will also improve her nutrient status of zinc, magnesium, iron, vitamin B6 and other B vitamins etc. all of which are key when it comes to osteoporosis.

Quitting coffee altogether will likely prevent any waking in the night – yes, even just one cup a day can make a difference – and also help improve the status of many of these nutrients. This is often the least favorite change my clients make but Merrilyn will read about all this in the caffeine chapter in my book and may find tyrosine helps her do so.

Research: Daytime tryptophan depletion altered night-time sleep

A paper published in 2002, Mid-morning tryptophan depletion delays REM sleep onset in healthy subjects, reports the following:

Rapid daytime tryptophan depletion in healthy volunteers significantly decreased plasma tryptophan levels during the day and the evening, followed by alterations in the characteristics of night-time sleep, including increased sleep fragmentation, REM sleep latency, and REM density during first sleep episode.

In this randomized double-blind cross-over study, participants received “a tryptophan-free mixture of amino acids at 10:30 am…. resulting in a 77% decrease and 41% decrease of serum tryptophan at 3:30 pm. and 9:30 pm.” Keep in mind that collagen is a blend of certain amino acids and is tryptophan-free.

The authors discuss the fact that serotonin is involved in sleep regulation but interestingly the mood of study participants was not affected.

Even more interesting is another study that found collagen used before bedtime improved sleep and cognitive function in physically active males. It’s possible it’s doing this because it is lowering serotonin that is too high.

Tryptophan and 5-HTP product options

Products I recommend include Lidtke 500 mg Tryptophan, and Pure Encapsulations 50 mg 5-HTP. 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, Doctor’s Best L-Tryptophan 500mg and Source Naturals 50 mg 5-HTP are products I recommend on iherb (use this link to save 5%).

Additional resources when you are new to using tryptophan or 5-HTP and other amino acids as supplements

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

Have you made the connection between your collagen consumption and anxiety/insomnia (or other low serotonin symptoms)?

Did you end up simply stopping collagen or have you successfully used it with tryptophan or 5-HTP?

If you’re a practitioner do you see this with your clients/patients who are prone to low serotonin?

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

Using tryptophan and GABA amino acid supplements together for anxiety, sleep, ruminations and TMJ: questions and answers

February 23, 2024 By Trudy Scott 18 Comments

I am taking 250 mg tryptophan, 100-200 mg GABA. Tryptophan is helping with rumination. GABA is helping with feeling less tension in the body. I am also taking 500mg DPA. DLPA used to help me but I thought it was too stimulating so I’m trying DPA now. I couldn’t feel much when taking it on its own.

But the combination of tryptophan, DPA & GABA is generally helping me to feel less wound up. I still struggle with rumination and I have a really difficult time making decisions. I get really overwhelmed when I have a lot of decisions to make – it sends me in a tailspin and leads to more rumination. I’m not sure which amino acid would be good for that?

I generally have trouble relaxing and feeling calm and I feel the tension in my body. I am not sure if I should try increasing the dosage of one of the above?

I am wondering, is it important to take l-tyrosine to balance the tryptophan since tryptophan can lower dopamine over time? Or is the DPA enough since it’s a precursor to tyrosine?

I get many questions like this about using both tryptophan and GABA amino acid supplements together for easing anxiety and today I’m sharing some of these questions and my answers. This will also give you the opportunity to ask questions you may have related to using both these amino acids together. You’ll also read many success stories like the above and how to tweak the amino acids for optimal results.

Read on for my response to the above question from TT and other questions about using GABA and tryptophan together – how to measure GABA and serotonin levels for using with teens, adding tryptophan for sleep separately from GABA, how to test both for jaw clenching, and the precaution about serotonin syndrome.

My response and feedback for TT – adjustments for even better results

My response and feedback for TT … It’s wonderful that this combination is helping so much. It’s a great start but there are adjustments I’d consider to get even better results. The tryptophan dose is low, with a typical starting dose of 500mg so I’d consider increasing this a few times over a few weeks to see if the ruminations decrease even further. This may also help with the overwhelm and decision making.

Increasing the GABA over a few weeks (after the trial of increased tryptophan) may well improve her ongoing tension and inability to relax. I’d want to make sure she is using GABA sublingually for the best effects.

She asks about the need to take tyrosine to balance the tryptophan but I don’t have clients do this as a rule of thumb and only have clients take tyrosine if they have symptoms of low dopamine. In this instance since TT mentions difficulties with decision-making, a trial of tyrosine may be worth considering, after she has increased tryptophan and increased GABA. More about tyrosine benefits here.

I do want to mention that DPA is not a precursor to dopamine but DLPA does offer some dopamine support. I share more about the differences between DPA and DLPA here.

I want to give my teens GABA and tryptophan – how do I measure GABA and serotonin levels?

I have two teenagers ages 14 and 16 who suffer from anxiety and depression. My daughter has more difficulty with depression and my son with ruminating thoughts . My father had similar issues. We have tried supplements, and medications that help a little.

I want to try giving them GABA and tryptophan, but to make sure that they in fact meet the criteria you describe. Is there a lab test that measures GABA and serotonin levels? Also, how can I figure out the dose and times to give them?

Here is my feedback for Maria …. The best way to determine if someone may have low GABA/serotonin is to look at the low GABA/serotonin symptoms questionnaire (here is that link), rate 1 or 2 symptoms on a scale of 1-10 with 10 being worst, do an initial one-off trial of the respective amino acid and rate the symptoms again right afterwards (in the next 2 to 30 minutes). Based on this we decide if we’ll continue with the amino acid and how much to use.

Dosing is unique to each person’s needs and timing differs for each amino acid – tryptophan is best mid-afternoon and evening and GABA throughout the day and evening if needed too.

I don’t use the urinary neurotransmitter test as it’s not considered an accurate assessment. I blogged about this here.

It’s a comprehensive approach – amino acids AND diet. This mom mentions supplements and medications but nothing about what their diets are like right now – gluten-free, sugar-free, caffeine-free, eating protein at breakfast for blood sugar control, real whole foods, grass-fed red meat, wild fish, fermented foods etc?

I also suggest my book “The Antianxiety Food Solution” as a great place to start when you are new to the amino acids and other anxiety nutrition solutions like gluten/sugar/caffeine removal, blood sugar control, gut health, pyroluria etc.

And this blog is a wonderful example and gives hope to moms – Tryptophan for my teenager: she laughs and smiles, her OCD and anxiety has lessened, and she is more goal oriented and focused on school. It’s one of many similar blogs so be sure to use the search feature to find others.

GABA and theanine help my anxiety, if I add tryptophan for sleep should I take it separately?

I have taken Gaba and L-theanine for anxiety for the last few years on and off as recommended by a doctor, it really does help although I still have sleeping problems. I also have a lot of symptoms on your low serotonin list so if I add tryptophan to see if it helps with sleep should I take it with the Gaba or separately?

Here is my response and feedback for Diane … I was glad to hear GABA and theanine are helping with the anxiety. I have many clients with low serotonin and low GABA symptoms take GABA, theanine and tryptophan at bedtime at the same time for improving sleep that is caused by low serotonin.

Diane has already identified that she has a lot of low serotonin symptoms from the questionnaire, so like I shared for Maria above, a trial is worth considering.

We always want to capitalize on what is already working so when GABA/theanine is helping with anxiety and offers some help with sleep we will often increase that before considering a trial of tryptophan.

I’m assuming she is addressing dietary factors too and other root causes that may also affect her sleep – like low blood sugar and high cortisol.

Would GABA or tryptophan help with jaw clenching and how do I test to see if they would help?

Would Gaba or tryptophan help with jaw clenching, not grinding, which I assume is an anxiety thing even when I’m unaware of any anxiety? Since I already use Gaba on and off for anxiety or if I can’t sleep (only taking 200 mg) how would I go about testing tryptophan to see if it would help for clenching?

Here is my feedback for Diane … Jaw clenching/TMJ (temporomandibular joint) issues can be related to both low GABA because of the muscle tension and also when serotonin is low.

In the same way we do a trial with the amino acids for anxiety or low self-esteem (or another symptom like cravings) we would do a trial for the jaw clenching i.e. rate the severity on a scale of 1-10 with 10 being worst, do a trial of tryptophan and then GABA (separately) and rate the symptoms again right afterwards (in the next 2 to 30 minutes). And go from there, increasing each as needed (one at a time) and tracking symptom improvement.

Here is a case as an example: Tryptophan ends TMJ pain, headaches and worry, and improves mood and sleep.

Precaution about serotonin syndrome with tryptophan/5-HTP

There are precautions when using certain amino acids and I always review them with all my clients. If they have been prescribed an SSRI, I have them discuss the use of tryptophan/5-HTP with their prescribing doctor so they can be monitored for serotonin syndrome. With careful monitoring and doctor approval I feel comfortable having my clients use tryptophan/5-HTP 6 hours away from their one and only SSRI.

If they are using more than one SSRI and/or a combination of psychiatric medications, the use of tryptophan/5-HTP is not advised.

None of the above applied in these situations but it’s important to be aware of.

Tryptophan and GABA product options

Products I recommend include Lidtke 500 mg Tryptophan, 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, Doctor’s Best L-Tryptophan 500mg and Source Naturals GABA Calm lozenges and Now GABA Powder are products I recommend on iherb (use this link to save 5%).

Additional resources when you are new to using tryptophan or GABA and other amino acids as supplements

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

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), if you need serotonin support, the Serotonin QuickStart Program is a good place to start. This is a paid online/virtual group program where you get my guidance on using tryptophan and 5-HTP safely, and community support during 5 LIVE Q&A calls. You can sign up to be notified when the next live launch of this program is happening. We take a deep dive into product options including Lidtke products and others if you’re not able to access Lidtke.

Low GABA can also affect sleep and cause stress eating. If you also have low GABA symptoms, the next step to get help is the GABA QuickStart Program. This is also a paid online/virtual group program where you get my guidance and community support. Another option is the budget-friendly GABA QuickStart Homestudy Program.

This blog is a follow-on from the previous blog on this topic so be sure to read that blog too. It also features many valuable questions in the comments and my responses, hence this new post. I hope this has been helpful for you.
