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?

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?

Glutamine for hypoglycemia/low blood sugar: “500mg mixed in water works in 15 minutes and keeps me going for 2 – 3 hours”

November 3, 2023 By Trudy Scott 27 Comments

Cat shared this feedback about how effective just 500mg of glutamine is for her low blood sugar and how quickly it helps:

I recently followed one of your posts on GABA down the rabbit hole to a linked blog post and then to another post where I found a mention of using glutamine for hypoglycemia. This is the only reference that I have read on this in 35 years of research on the subject. I follow a low carb, higher protein, healthy fat diet, but still suffer low blood sugar issues consistently at one particular time of the day. After so many years of eating a second breakfast to prevent the lows, I was ready to give any other healthy option a try.

It works!!! I found a powder that I mix approximately 500 mg of with water. It works within about 15 minutes and keeps me going for about 2 – 3 hours — long enough to reach a reasonable time for lunch.

I’m thrilled to have this option as anytime that I travel, low blood sugar becomes a huge issue as I suffer from ketotic hypoglycemia and end up with massive headaches and vomiting for 6-8 hours.

You have freed me from a huge weight! Thank you and hugs!

(And thank you for researching and sharing the tremendously helpful information in your books, webinar presentations and blogs.)

Thank you Cat for sharing your success and you are most welcome! I’m sharing this as a blog post because you may also be new to this.

Glutamine dosing, using powder vs capsules and using it on the tongue

Cat finds 500 mg glutamine works well for her unique needs. This is a good starting dose. I see many folks start too high, like 5000 mg / 5 g and up multiple times a day, and it’s not necessary. However, we increase based on individual needs and you may find you do need to use 500 mg -1000 mg two to three times a day.

Using a glutamine powder is a great way to use it especially if you find you do need more than 500 mg each time.

One thing I mentioned to Cat is when you use glutamine powder directly on to the tongue (rather than mixed in water), the benefits are seen more quickly i.e. right away rather than having to wait 15 minutes.

If you do start with glutamine capsules, be sure to open the capsule on the tongue too, But watch for fillers which can be irritating to some folks. Powders are typically glutamine-only and don’t taste bad at all. But when traveling, capsules may be a better option (at least when on a plane).

Ketotic hypoglycemia, adrenal dysfunction and breakfast

Ketotic Hypoglycemia International defines ketotic hypoglycemia as “a condition characterized by low blood sugar (glucose) and elevated ketones, typically occurring after fasting, like sleeping overnight. Ketotic hypoglycemia (KH) is not a disease itself but rather a symptom or a clinical presentation that can occur as a result of various underlying conditions.” I’ve asked Cat if she is aware as to what is causing her ketotic hypoglycemia and I’ll report back.

I have also asked if she has had salivary cortisol testing done as adrenal dysfunction plays a role in all types of low blood sugar and will need to be addressed. This can take awhile to test and figure out nutritional support. Until then, glutamine is wonderful for preventing low blood sugar episodes.

I’m also curious what her breakfasts look like and will update the blog when I find out. Cat does mention that she follows “a low carb, higher protein, healthy fat diet” so I assume her first breakfast is a good one. But it’s always something to confirm. As you can see on this blog, Anxiety and Hypoglycemia Symptoms Improve with Diet Modification, a healthy breakfast is key for blood sugar stability and preventing anxiety.

Low blood sugar symptoms and all the ways glutamine may help

This is the blog she commented on: Glutamine for calming, intense sugar cravings, gut healing and low blood sugar

I share all the symptoms we see with low blood sugar:

Crave sugar, starch or alcohol any time during the day
Irritable, shaky, headachey – especially if going too long between meals
Intense cravings for sweets
Lightheaded if meals are missed
Eating relieves fatigue
Agitated, easily upset
Nervous, anxious, panic attacks

As you can see, in addition to helping with low blood sugar symptoms, glutamine has calming properties (low blood sugar can also cause anxiety and panic attacks), helps reduce intense sugar cravings (sometimes described as a demonic urge to eat all things sweet and also helps with healing a leaky gut. Be sure to read these two blogs I’ve linked to above.

Glutamine has also been researched to help with addiction recovery. In this blog, An amino acid supplement with DLPA, glutamine and 5-HTP eases alcohol withdrawal symptoms at an inpatient detoxification program, glutamine is paired with two other amino acids.

Resources if you are new to using glutamine and other amino acids as supplements

We use the symptoms questionnaire to figure out if low blood sugar may be an issue for you.

If you suspect blood sugar or 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 topic has an entire chapter), sugar cravings, anxiety and mood issues.

I really appreciate Cat for sharing her story and giving me permission to share as a blog.

Has glutamine helped you with low blood sugar/hypoglycemia? If yes, in what way has it helped – reduced anxiety, less sugar cravings (or other addictions), and not as irritable and cranky/angry?

And how much helps and how quickly? Are you using it on the tongue?

Has glutamine also helped with leaky gut?

If you’re a practitioner are you using glutamine this way with your clients/patients?

My 12 year old son has ADHD, is impulsive, is a loner, craves carbs, and doesn’t do well or care about school – should he be on GABA?

July 21, 2023 By Trudy Scott 17 Comments

I’ve been reading your blogs and I’m trying to decide if my 12 year old son should be on GABA? He has ADHD, is impulsive, is a loner, craves carbs, and doesn’t do well or care about school.

Can you tell me what supplement he could be deficient and where to purchase? He is currently on ADHD medication (Focalin) during the school year.

Janice asked the above question about her 12 year old son. I wish it was as simple as just using the calming amino acid GABA but it’s seldom one amino acid that is the answer. GABA is often one of many supplements that may help and in this instance I suspect a combination of neurotransmitter imbalances (low GABA, low dopamine and low serotonin), pyroluria, other possible nutritional deficiencies and dietary factors are at play. Read on to hear my approach for working through what may help this young man improve his focus, reduce his carbs, actually care about school and doing well, reduce his impulsivity and help him fit in socially – and ultimately lead to him being a happier, calmer and healthier child.

GABA with preteens who have ADHD and spinning-type symptoms

I always start with one of the amino acids because we get quick results and immediate feedback. Since Janice asked about GABA, this is the GABA feedback I shared with her: I’ve had good results with GABA with preteens who have ADHD and spinning-type symptoms. One clue is when the craving of carbs is driven by stress i.e. stress eating. I always start with the symptoms questionnaire and have the parent rate each low GABA symptom on a scale of 1-10, with 10 being most severe, ideally in conjunction with their child.

I then have the child do a one-off trial of GABA and we observe improvements in the next 5-30 minutes. If the child reports any improvement in any of the symptoms – in this case focus and spinning driven by anxiety – the child continues with GABA and increases over the next few weeks to find the ideal dose for their needs.

Sometimes focus issues are so severe that it’s too challenging to rate symptoms before, doing a one-off trial of GABA and then rating symptoms afterwards. In cases like this, mom makes the decision to have their child use GABA before school, when they get home and possibly early evening too. Mom can observe their focus and spinning: like getting dressed and ready for school, settling down to homework in the afternoon and settling down for bed.

Relying on feedback from school is invaluable too. Stress related carb cravings are also assessed i.e. does he seek out sugar when stressed and anxious.

A mom shares how GABA helps her 11 year old daughter – GABA for children: ADHD, focus issues, irritability, anxiety and tantrums

My daughter hasn’t been diagnosed with ADHD but has a lot of ADHD qualities. We were having a huge amount of behavior problems as she is getting older (she’s 11). She has had amazing behavior at school and at home since giving it to her. She’s almost like a different child. GABA has truly changed our life.

…before the GABA she was irritable, she was fighting with her teacher and schoolmates, she couldn’t focus and was distracted by anything and everything, she was constantly disrupting the class and she was throwing major tantrums over ridiculous stuff (like her hair didn’t do what she wanted), she was mouthy and everything was a fight.

We are not seeing 99% of those behaviors at all anymore. She of course is still your typical pre-teen but if I say “no you can’t have that” our “no you can’t go there” her reaction is OK. Before it would have been a major fight or meltdown. Her teacher is reporting to me every day about her wonderful days.

Tyrosine for focus issues, low motivation and low energy type carb cravings

With focus issues I would also consider the role of low dopamine and do a trial of tyrosine. Other clues: are his carb cravings related to low energy and is there also low motivation tied to the fact that he doesn’t care about school? Are there also signs of depression or low mood?

We go back to the symptoms questionnaire and have the parent rate each low dopamine/low catecholamine symptom on a scale of 1-10, with 10 being most severe. Again, do this in conjunction with the child if possible.

We only do a trial of one amino acid at a time so we know what is working. Assuming the GABA has been helping, we’d do a trial of tyrosine next and look for improvements in focus, carb cravings (all neurotransmitter imbalances can lead to carb cravings), motivation and mood.

If the one-off trial approach is not an option, tyrosine is also used before school and right after school but no later than 3pm so as not to affect sleep. Again, the above symptoms are tracked.

In this blog both GABA and tyrosine help this teen: GABA helps 14-year-old with Tourette’s Syndrome (the tics and sleep), and tyrosine makes him happier and his mind sharper

Tryptophan or 5-HTP for ADHD/hyperactivity and afternoon cravings

Hyperactivity can also show up with low serotonin, and so can something like not caring about school i.e. a low mood. A clue here is when his carb cravings are more intense – with low serotonin it’s typically afternoon or evening.

We go back to the symptoms questionnaire and have the parent rate each low serotonin symptom on a scale of 1-10, with 10 being most severe. And again, it’s best to do this in conjunction with the child if possible and do a one-off trial of tryptophan or 5-HTP.

If that’s not possible, tryptophan or 5-HTP is used mid-afternoon and evening and symptoms are tracked. This can be layered in on top of the GABA and tyrosine if they are offering some relief.

Here is a blog post where a mom shares how 5-HTP helps her child – ADHD: 5-HTP melts have been a miracle for one of my adopted kids

5-HTP melts have been a miracle for one of my adopted kids. He had lots of trauma and off the charts ADHD. 5-HTP is better than methylphenidate (Ritalin) and we are now weaning off the non-stimulants.

Just 80 mg 5-HTP in the morning is all he needs. He was super ADHD, he had a para (teacher’s aide) in public school for years to keep him on track and this year at a school for ADHD the teachers were complaining that he was never on task. Now after a week it has changed his life.

Addressing pyroluria, low lithium, low zinc, low blood sugar and diet

Janice mentions her son is a loner so we’d look into pyroluria/social anxiety and add zinc, vitamin B6 and evening primrose oil (and other key nutrients). Keep in mind that zinc deficiency is common and is often low with ADHD.

She also mentions that he is impulsive. Impulsivity and ADHD is common with low levels of lithium. A big clue is a child having a roller-coaster of emotions. I use this low lithium questionnaire to assess for a need for low dose lithium (a nutritional supplement).

I consider low blood sugar with all my clients and with this young man low blood sugar may be contributing to his focus issues, low mood and desire for carbs. The amino acid glutamine helps as does breakfast and meals with quality animal protein and healthy fats.

And it goes without saying that dietary factors must always be addressed. My book is a great resource when are looking for a comprehensive dietary approach, which is needed with ADHD and the symptoms Janice describes – The Antianxiety Food Solution. There is also a chapter on low blood sugar, pyroluria and the amino acids.

If you are an adult and can relate to any of these symptoms and feelings, the same process applies. Just remember this: there is no one-size fits all since we all have unique biochemistry.

Side effects and longer term effects of stimulant medications

I appreciate Janice for reaching out and asking this question. Hopefully, implementing some or all of these changes, will allow her son to stop his stimulant medication, Focalin. This medication is similar to Ritalin (methylphenidate), which can cause the following side-effects: feeling sad or empty, irritability, loss of interest or pleasure, trouble concentrating, trouble sleeping (and many more).

These stimulant medications can also play a role in longer term health effects that include heart disease and the possibility of it being a gateway drug to other stimulants. The research on the latter is hotly debated but it is often seen clinically.

Resources if you are new to using amino acids as supplements

To recap, if you are new to using 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, low serotonin, low dopamine, low blood sugar and low endorphins).

As mentioned, 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.

Have any of the above amino acids helped your child or you with the following symptoms: ADHD and poor focus, carb cravings and low mood/low motivation (doesn’t care)?

Has the pyroluria protocol helped your child or you be less of a loner?

Has low dose lithium helped your child or you with impulsivity and focus issues?

Have dietary changes helped too?

If you are a practitioner, are you using amino acids, the pyroluria protocol, low dose lithium and dietary changes with success in cases like this?

GABA supplementation may offer a new approach for the prevention and treatment of asthma (and it helps anxiety, ADHD and insomnia)

December 16, 2022 By Trudy Scott 12 Comments

If you’re already taking the amino acid GABA for physical anxiety, have you noticed if it’s also helping to ease your asthma symptoms too? This may sound surprising but research shows GABA may reduce inflammation and spasms and help with asthma symptoms via these mechanisms. What’s encouraging is the fact that GABA supplementation also helps with anxiety, obesity, ADHD and insomnia which commonly occur with asthma and can be associated with inflammation too. It’s so important to be addressing the root causes of asthma because of the many neuropsychiatric side-effects of asthma medications. This blog addresses all of these topics.

We’ll start with the research first. In this study, Effect of gamma-aminobutyric acid treatment on plasma substance P and calcitonin gene-related peptide levels in children with asthma, of 75 children with asthma, 36 children were in the GABA treatment group and received oral GABA (25-30 mg/kg per day) in addition to standard asthma medications.

The authors propose that airway inflammation may be a factor in asthma and GABA helps because it reduces SP (substance P) and CGRP (calcitonin gene-related peptide), easing neurogenic inflammation and tracheal spasms.

The conclusion of the study is that oral GABA:

can significantly decrease plasma levels of SP and CGRP in children suffering from acute asthma.

It may offer a new approach for the prevention and treatment of asthma.

(this is my best translation from the Chinese paper).

Dosing of GABA for asthma

The children in the study group received oral GABA of 25-30 mg/kg per day. For a 100 lb /45 kg child this would equate to 1125 mg -1350 mg of GABA per day.

As I always share, I don’t recommend using GABA based on the weight of the person and I consider this a high dose. For adults, 125 mg GABA is a good starting dose with 125 mg often used 2-4 times a day. For a child, ¼ to ⅓ this dose is typically good to start with. All that said, many adults and children with asthma and anxiety need higher doses than what they initially start with.

It’s also worth noting that the oral dose of GABA was swallowed so it’s possible (and very likely) that more was needed than if it was used sublingually or with the capsule opened or a powder or a liposomal form.

GABA is seldom recommended for asthma – more recent research supports this approach

This is not new research – the paper was published in 2013 – but I seldom see it discussed or hear about practitioners recommending GABA for asthma.

A more recent paper, Neuroimmune Pathophysiology in Asthma (published in 2021) supports this and discusses the role of neurotransmitters (including GABA and serotonin) and neuropeptides (including SP, CGRP and others) in asthma. The authors suggest “that regulating the effects of neurotransmitters and neuropeptides represents a potential novel approach for the treatment of asthma.”

Why we need to consider GABA – the neuropsychiatric side effects of asthma medications

Exploring the use of GABA and these approaches is especially important given the neuropsychiatric side effects of asthma medications. In this study (published in March this year), Neuropsychiatric adverse drug reactions induced by montelukast impair the quality of life in children with asthma

Neuropsychiatric ADRs (adverse drug reactions) were reported in 78 (62.4%) of 125 patients, who recovered when the drug was discontinued.

These were children of 3-18 years taking montelukast for the first time. The good news is that they recovered when the drug was stopped.

The bad news is there is no information on how many kids who have been prescribed this class of medication are subsequently prescribed psychiatric medications.

This concern needs to be considered for all asthma medications: there are similar adverse effects with antihistamine and inhaled corticosteroid medications.

GABA helps with other conditions where spasms are common

The study results are very encouraging and support what I see clinically with asthma and other conditions where spasms are common. These include

GABA helps with all of the above and the non-allergic comorbidities seen with asthma.

Asthma in children and non-allergic comorbidities (obesity, depression and anxiety, ADHD and insomnia)

As stated in this paper, Paediatric asthma and non-allergic comorbidities: A review of current risk and proposed mechanisms “It is increasingly recognized that children with asthma are at a higher risk of other non-allergic concurrent diseases than the non-asthma population.” These include obesity, depression and anxiety, neurodevelopmental disorders (such as ADHD), sleep disorders and autoimmune diseases.

This paper looks at mechanisms and inflammation is a common theme except when it comes to anxiety and depression. Given that this paper was published this year and all that we now know about nutritional psychiatry and neuroinflammation and anxiety, it’s clearly lacking in this aspect.

Clinically, we see how GABA can help with obesity (and cravings or stress-eating), depression and anxiety, ADHD and insomnia, as illustrated by these case studies:

I see similar comorbidities (the occurrence of more than one disorder at the same time) in adults and GABA can be used safely with adults and children.

Asthma from a functional medicine approach

There is clearly more to asthma than only GABA. This this article on natural remedies for asthma covers diet (eat real good quality food and avoid junk food), nutrients like vitamin D, zinc and others, and allergens – and all this needs to be investigated and addressed with a functional medicine approach.

Dr. Axe does mention stress and anxiety being a trigger: “It’s well-known that stress increases the severity and frequency of asthmatic attacks because it hinders immune function and raises inflammation.” He mentions stress-reduction techniques and breathing. I say let’s add GABA to the mix too.

Resources if you are new to using GABA and other 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.

Has GABA helped ease your physical anxiety and asthma symptoms too?

What about obesity/cravings, ADHD and insomnia as well?

Have you or one of your children been adversely impacted by asthma medications? If yes please share which medications and what symptoms were experienced.

What functional medicine and nutritional approaches have helped your asthma symptoms?

Rage, anxiety, cravings & insomnia in 11-year old girl with RAD/reactive attachment disorder: chewable tryptophan turns things around

May 28, 2021 By Trudy Scott 21 Comments

Today I’m sharing the case of an 11-year-old girl who had huge rage issues, was angry much of the time, suffered from terrible anxiety, had crazy sugar cravings (for bread and colored candies) and had dreadful insomnia. Because of the insomnia she was also very fatigued and this likely drove some of her cravings and irritability too. She was adopted and had been diagnosed with RAD (reactive attachment disorder). During our first session, chewable tryptophan turns things around quickly – she smiles and is willing to make changes and quit the sugar and gluten. We also address low iron levels and with these 4 nutritional interventions this child’s behavior improves dramatically.

This book chapter, Reactive Attachment Disorder, states how The Diagnostic and Statistical Manual 5th Edition (DSM-5) classifies reactive attachment disorder as follows:

a trauma- and stressor-related condition of early childhood caused by social neglect or maltreatment. Affected children have difficulty forming emotional attachments to others, show a decreased ability to experience positive emotion, cannot seek or accept physical or emotional closeness, and may react violently when held, cuddled, or comforted. Behaviorally, affected children are unpredictable, difficult to console, and difficult to discipline. Moods fluctuate erratically, and children may seem to live in a “flight, fight, or freeze” mode. Most have a strong desire to control their environment and make their own decisions. Spontaneous changes in the child’s routine, attempts to discipline the child, or even unsolicited invitations of comfort may elicit rage, violence, or self-injurious behavior.

Reactive attachment disorder/RAD and low serotonin

There is no research on tryptophan helping to address RAD symptoms or trauma, but based on her low serotonin symptoms, a trial of tryptophan was the first thing I considered.

There is, however, evidence to indicate the role of low serotonin in RAD, as indicated by a study where antidepressants were successfully used. The authors mention how:

The absence of responsive and consistent caretaking can subject the developing brain to an inordinate amount of physiological stress, leading to increased cortisol production and consequential inefficiencies in the serotonin and the growth-hormone releasing systems.

Although not specific to RAD, another paper looking at trauma states that:

Serotonin and dopamine levels were found to be abnormal in the presence of PTSD.

As the field of nutritional psychiatry grows, I expect to see more and more research supporting the use of tryptophan and other amino acids for those suffering from symptoms like this. Symptoms that are caused by imbalances that are triggered by the trauma in their lives.

We know that therapy, EFT, EMDR and other approaches are crucial for trauma recovery (this family had already done some of this work) but we must start to incorporate nutritional support too.

The case study

Here are the details of this case study and the nutritional interventions. As I mentioned above, because of her severe rage episodes, a trial of tryptophan was the first thing I considered:

She was referred to me by a friend. The family didn’t have much money. And so, we had to really try and figure out a few simple interventions that we could use that were going to be effective.

This young girl had been adopted. She was diagnosed with reactive attachment disorder and her anger issues were just phenomenal. The mom had to physically put her body around her and hold her down when she was having one of her fits because she was worried that she was going to hurt herself and hurt other people.

She also had anxiety, huge cravings for colored candies and insomnia. She was so fatigued because she wasn’t sleeping well.

So sitting in my office with this young girl and her mom, we started to talk about the sweets and the candies and the need to give up the candies. She was fuming with me. She was sitting in a swivel chair. She turned her back on me and didn’t want to talk about having to give up candy at all.

I said, “Look, let’s not even talk about that, but would you take this chewable tryptophan here? And we’ll talk about it in a second.” I gave her 100 mg of the chewable tryptophan and continued discussing things with her mom. She had no idea what it was going to do or how it would make her feel.

Within five minutes she turned her chair back, looked at me and she said, smilingly, “Yes, let’s do it. I can give up the candy.” She was smiling and she was happy.

So long story short, with this young girl, we started her on [chewable] tryptophan [and it turned things around quickly].

Chewable tryptophan – when I use it and when I don’t

I typically use 500mg Lidtke tryptophan for the adult clients I work with and prefer this company’s product because it is really high quality. It really does work better than many other tryptophan products on the market.

Lidtke also makes a chewable 100mg tryptophan which is also high quality, and the product I used with this young girl. Here are some benefits of this 100mg product:

It’s useful for doing the initial trial in order to figure out if tryptophan is going to help with low serotonin symptoms in children – because it’s a lower dose.
It’s especially useful for children for ongoing use (typically midafternoon and evening) because it’s a lower dose.
It’s also useful for adults who are “pixie dust” folks and do better with a lower dose of supplements in general or respond more severely to medications/alcohol/chemicals. We may start with a trial of the 100mg chewable and increase from there, also typically midafternoon and evening.

I don’t use the chewable 100mg tryptophan under these circumstances:

When the child (or adult) finds that 5 x100mg works for them at each time they need it. In this instance it’s best to switch to a 500mg tryptophan. Using it swallowed may work or it may need to be opened onto the tongue.
When the child (or adult) starts to consume the chewables like candy. They are sweet and do taste good and I’ve seen this happen. Because you are continually consuming something sweet you may end up over-consuming them if sugar addiction is one of your issues. You may also end up taking too much tryptophan.

If the chewable tryptophan is not available where you live, using a small amount of a powdered tryptophan or opening a capsule of the 500mg tryptophan is an option. Since it tastes bitter it can be mixed with mashed banana or inositol. (You can find all the Lidtke products in my online supplement store. The link is in the resources section below.)

Gluten and candies were also a huge issue, and she had low iron

There was more to her issues than only low serotonin:

Gluten was also a huge issue, so we got her off gluten and the candies. The tryptophan helped with this” (i.e. it made it easy to break the addiction and not feel deprived).

Tryptophan also helped her sleep. And it helped with the severe rage issues.

Obviously the gluten was contributing to the rage issues as well.

Her iron and ferritin levels were really low (possibly as a result of her gluten issues). So we added an iron supplement, and animal protein/red meat.

So with just four interventions – the gluten, the animal protein, getting her iron levels up and the tryptophan – this kid was just a new kid.

Here are some articles that are related to the above:

The role of low serotonin, low vitamin B6 and low iron in anxiety and panic attacks
Integrative Medicine Approach to Pediatric Obsessive-Compulsive Disorder and Anxiety I write about a study where gluten was found to be the cause of a childhood case of obsessive-compulsive disorder (OCD)
Tryptophan for my teenager: she laughs and smiles, her OCD and anxiety has lessened, and she is more goal oriented and focused on school.

Keep in mind there is not a one-size-fits-all and these 4 simple nutritional interventions – tryptophan, gluten removal, adding red meat and addressing low iron – happened to be the combination that worked for this young girl.

Resources if you are new to using tryptophan as a supplement

If you are new to using the amino acid tryptophan as a supplement, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

If you suspect low serotonin symptoms 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 so you are knowledgeable.

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 Lidtke chewable tryptophan 100mg, Lidtke tryptophan 500mg and other products that I use with my individual clients and those in my group programs.

We use an amino acid like tryptophan for quick relief of symptoms, like I did in this instance. Then we focus on the foundations like diet – like no gluten and red meat in this instance – and address all other imbalances, like her low iron. If cortisol was high we would have addressed that.

This case deserves it’s own blog post

In case you’re wondering, I first shared this case study in my interview, “Calming Anxiety, Aggression and OCD with Amino Acids and Food”, on the ADHD and Autism Summit in May 2021. Due to the interest in this case and the use of chewable tryptophan, I felt it deserved a deeper dive and its own blog post with links to some of the research and some practical information about the chewable tryptophan.

Have you used this chewable tryptophan product with success – personally, with your child or with a patient/client?

Have you found that addressing serotonin with tryptophan (or 5-HTP) helps resolve symptoms in a child diagnosed with RAD or a child with rage issues? What about helping with sleep problems, easing anxiety and stopping cravings too?

Have you addressed low iron levels and seen improvements with the removal of gluten too.

Feel free to post your questions here too.
