worry

Flight anxiety with heightened breath, physical tension and also fearing the worst (the role of low GABA and low serotonin)

September 19, 2025 By Trudy Scott Leave a Comment

Do you have suggestions for supplements for flight anxiety, something to make flying bearable without heightened breath, etc, or is that out of the supplement realm?

I also have physical tension and fear the worst. Any kind of turbulence or warnings of turbulence makes me extremely nervous.

K asked this question on one of my blogs and I responded that this is very much in the supplement realm! And what we use depends on the type of anxiety someone is experiencing.

I would first consider serotonin support before and during flying – tryptophan or 5-HTP – because she fears the worst and feels extremely nervous. With low serotonin there may also be worry and fear leading up to the trip, as well as feelings of panic and imagining the worst during the flight.

GABA support – using the amino acid GABA or theanine – should also be considered for the more physical symptoms of heightened breath and physical tension. With low GABA there can be other physical symptoms such as excessive sweating (like the palms), a racing or pounding heart and a dry mouth. These amino acids could also be used leading up to the flight and during the trip if needed.

Read on for more on my insights on using these amino acids in a situation like this, additional information about fear of flying and a success story with GABA.

Serotonin and/or GABA support for fear of flying

In an ideal situation I would want to address both low serotonin and low GABA before flying and have her use extra during the flight, as needed. It’s very likely that many of the low serotonin and low GABA symptoms are present in some way in her day to day life too.

This means she can be methodical about doing a trial of the respective amino acids and figure out the optimal dose of each in familiar surroundings – using powder, capsule opened, sublingual, chewable or liposomal.

As always we trial one at a time so we know which one is working best. Keep in mind some folks do better with tryptophan and some do better with 5-HTP so both may need to be trialed. The same can be said for GABA and theanine.

Once the product and dose of each has been figured out, she’ll need to find a suitable option for use while traveling i.e. a sublingual or chewable tablet

It’s always a comprehensive approach

It’s a comprehensive approach – amino acids AND diet so I recommend eating real whole food, quality animal protein, eating for blood sugar stability, going gluten-free, sugar-free and caffeine-free, eating healthy fats, organic vegetables and fruit and fermented foods. My book “The Antianxiety Food Solution” is 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.

During travel it’s important to be prepared with healthy travel foods and drinks. I share some ideas here.

The definition of a specific phobia such as the fear of flying

The fear of flying is called aviophobia and it’s one of many common phobias about something specific. According to this ebook

Specific phobia is an anxiety disorder characterized by excessive and irrational fear of a particular object, situation, or activity. The anxiety response goes beyond normal apprehension and leads to avoidance behavior. The intensity of the fear is often disproportionate to the actual danger posed by the phobic stimulus.

Common examples of specific phobias include fear of heights (acrophobia), fear of spiders (arachnophobia), fear of flying (aviophobia), and fear of needles (trypanophobia). People with specific phobias may experience intense anxiety or panic attacks when exposed to the feared object or situation.

This Australian article reports that “One in six people have a significant fear that prevents them from flying, and about one in five regular flyers use alcohol or prescription drugs to “help” them through a flight, according to Victoria’s Department of Health.”

Using the amino acids to address low serotonin and/or low GABA addresses the root cause and does away with the need for alcohol and antianxiety meds (and the associated side-effects).

Cognitive behavior therapy (CBT) and exposure therapy is often recommended for aviophobia but doesn’t always help, and doesn’t address the biochemical imbalances.

A success story with GABA before and during a flight – cool as a cucumber

Melissa started using Source Naturals GABA Calm in anticipation of holiday travel and holiday gatherings and shared this:

I’m glad I saw the post about GABA on your FB page a couple weeks ago. I bought Source Naturals GABA Calm and have been taking 1-3 per day for two weeks.

I’m glad I bought it before travelling home for Christmas – I was cool as a cucumber at the airport and was much calmer when visiting family and friends compared to last year! The true test of its efficacy will be in two weeks when the semester starts. For now, I notice a general calmness and am sleeping well.

Notice that she started using it in the 2 weeks leading up to her trip and not on the flight itself.

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 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 importance of quality animal protein and healthy fats is also covered.

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.

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 need serotonin support, the Serotonin QuickStart Program is a good place to get help. This is also 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.

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.

Have you had success using serotonin and/or GABA support for your fear of flying (or other phobia/s)? If yes, which amino acids have helped you?

Did you have any success with CBT or exposure therapy or other approaches?

Tryptophan and GABA for relaxation, jaw pain, sleep, anger and mood symptoms

June 13, 2025 By Trudy Scott 10 Comments

I typically start clients on tryptophan if they have signs of low serotonin: stressed, overwhelmed worry, fears, obsessing, feeling anxious, ruminations, low mood, anger issues/rage, sleep problems, pain issues, PMS, low self-esteem, imposter syndrome, and afternoon/evening carb cravings etc. If we don’t get expected results we switch to 5-HTP as some people do better on one vs the other.

With signs of low GABA – a more physical kind of anxiety, with some overwhelm, intrusive thoughts, tension, sleep issues (often lying awake tense), stress-eating and/or drinking and pain – I typically recommend a GABA only product (as a powder or capsule opened) or GABA Calm (a sublingual). In some cases we may consider theanine and pharmaGABA.

The best way to assess low GABA and low serotonin is the symptoms questionnaire and a trial of the respective amino acids – one at a time. But the key is to find the ideal amount for the unique needs of each person. We do that by methodically and systematically increasing the amino acid slowly and tracking improvements for each increase.

In this blog you can read some success stories from women who used tryptophan and GABA for relaxation, jaw pain, sleep, anger and mood symptoms, and my commentary with some additional insights.

Tryptophan and GABA (as powders) – for her stress and pain

Amy uses both tryptophan and GABA for relaxation and jaw pain:

I use both tryptophan and GABA, I just take them separately. When my jaw was really bad the tryptophan really helped. I also do vagus nerve stimulating exercises that make me yawn and it stretches and releases the jaw.

As for the GABA …when I’m very stressed, I need extra to feel the effects. I use a pinch between the fingers of the Now powder and let it dissolve on my tongue. I feel my body relax in about 30 seconds. If nothing then I take a second pinch. Most days 1 pinch is enough.

I also let tryptophan dissolve in my mouth and most days I feel the same physical relaxation after a few moments. It’s not always obvious with the tryptophan though. I use 1/4 tsp of powder but you can use capsules. I mix the powder with pudding powder because it’s very bitter.

Both tryptophan and GABA can help with pain, and also feeling anxious and stressed.

The benefits are via different mechanisms – tryptophan boosts low serotonin and it’s typically more of a mental type of relaxation. This blog illustrates the use of tryptophan for TMJ (temporomandibular joint) – Tryptophan ends TMJ pain, headaches and worry, and improves mood and sleep: a success story.

The amino acid GABA boots low GABA levels and it provides more of a physical type of relaxation and also helps with pain relief.

I like that Amy is using both amino acids as powder and I’m happy for her. GABA powder tastes pleasant and is much more effective used this way (or capsule opened or sublingual).

Tryptophan can be swallowed but many find it more effective as a powder or capsule opened. As Amy says, it’s very bitter as a powder.

Tryptophan or 5-HTP and different forms of GABA – for sleep, anger and mood symptoms

Kerry tried 5-HTP and pharmaGABA but did better with tryptophan and GABA Calm:

My naturopath had me on 5-HTP but I never felt a benefit, and pharmaGaba was a histamine trigger. After reading your book I tried tryptophan and spent many months on 2 x 500mg at bedtime. This helped with sleep and definitely stopped the surges of anger that happened often.

I read a lady say her staple was 2 x Gaba Calm at bedtime and on rising, so I tried this and it helped.

I now take both tryptophan and Gaba Calm only if I feel niggly mood symptoms.

My previous diet was standard vegetarian, then vegan for several years. I now have lots of protein in the form of beef liver capsules, eggs and protein powder. I don’t like meat.

Kerry shared all this in a recent blog comment, describing how tryptophan and GABA Calm were big game-changers for her, in addition to “a long slow mold detox …addressing nutritional deficiencies and implementing dietary changes.”

Mycotoxins caused by mold, nutritional deficiencies and a poor quality diet can impact neurotransmitter production. The good news is that when you find the right combination of amino acids – in this case tryptophan and GABA Calm – you can get relief right away while the other factors are being addressed. It reduces the overwhelm, stress and fears too.

Kerry’s approach of consistent use of both amino acids is the best way to go and I’m so happy for her. And once levels are sufficient they can be used as needed, provided other underlying causes (like toxins, diet etc) are being addressed.

I will add that some individuals do better on 5-HTP and some do better on tryptophan so it’s often a matter of doing a trial of both. I typically recommend tryptophan to start because 5-HTP can be an issue if cortisol is high.

I also always recommend starting with some forms of GABA because of the potential histamine issues with pharmaGABA. That said, some individuals do tolerate pharamGABA so it’s worth doing a trial of both. And we may also consider theanine when we want to support low GABA, low serotonin and low dopamine.

Theanine and tryptophan and diet/lifestyle changes – and feeling her best!

Luna worked with a health practitioner to taper off Prozac (very slowly) and used amino acids during the taper and afterwards:

As someone who took Prozac for years and eventually came off, please pay special attention to Trudy’s advice to come off it SLOWLY. I’d say do it so slowly it may seem ridiculous.

I tried three times to get off Prozac and it was only with the help of an ND/PharmD did I finally get the info needed to come off it without *awful* side effects. To do it well, the process takes MONTHS – not weeks as many doctors recommend.

These days, I take L-Theanine and L-Tryptophan. And I’m preparing to add some GABA soon. Combined with daily 45 minute walks outside, and a low-sugar/low-gluten diet, I’m doing the best I have in my adult life.

A comprehensive approach that includes amino acids, dietary changes, and getting out in nature can make a world of difference. I love it when I hear feedback like this.

Would using 5-HTP or tryptophan help when you crave sugar (as a sort of antidepressant) late afternoon/evening?

June 2, 2023 By Trudy Scott 29 Comments

Would using 5-HTP or tryptophan also help when you crave sugar (as a sort of antidepressant) late afternoon/evening? ~ Kimberley

This question was posed in response to my recent blog post about using tryptophan or 5-HTP to help with alcohol cravings/addiction in the late afternoon/evening – to help you wind down and relax, improve mood and sleep, and also as a reward/treat.

I said yes it is often the same cause when it happens late afternoon/evening and when there are other low serotonin symptoms like low mood, anxiety, worry, insomnia etc. When serotonin is low we self-medicate with wine, sugar, carbs, gluten, dairy and chocolate etc. in order to feel good, get a mood boost and reduce stress. 5-HTP or tryptophan stops the sugar cravings, acts as an antidepressant (improving mood) and eases other low serotonin symptoms too.

It turns out Kimberley was craving sugar late afternoon: “it’s definitely late afternoon for me, while I’m making dinner. Maybe it’s time to go back on 5-HTP.”

And then 2 days later she posted how quickly 5-HTP helped when she added it back mid-afternoon:

I was taking a break from tryptophan/5-HTP and realized after reading this post that that might be a mistake! So I added 5-HTP back in mid-afternoon and my sugar cravings are almost completely gone. It’s funny how I forget the symptoms of low neurotransmitters. Thanks for reminding me!

5-HTP works quickly when it’s low serotonin

How wonderful are these results for Kimberley. I never get tired of hearing feedback like this! I appreciate her sharing and giving me permission to share as a blog so you get to learn and be inspired too.

It’s not unusual for 5-HTP to work this quickly and when it does it’s a clue that the symptoms are related to low serotonin and that she found the ideal dose for her needs.

Kimberley had good results with 5-HTP in the past so she went back to what had worked for her before and it worked for her again.

But do keep in mind, some folks do better with 5-HTP and some do better with tryptophan so it’s a matter of doing a trial of each one each.

50 mg 5-HTP: the sadness and despair lifts in a few minutes

A week later she kindly came and shared additional details in the comments of the tryptophan/ 5-HTP alcohol cravings blog, saying:

It’s possible that I was already in the middle of my daily, mid-afternoon chocolate chip binge when I saw your post

I took a 50 mg 5-HTP along with my mid-afternoon Endorphigen capsule, and within just a few minutes I felt the sadness and despair that I often feel in the late afternoon, start to lift. I was astonished at how quickly it worked! I didn’t open the capsule, or chew it, I just swallowed it with water and had a snack afterwards. I really can’t thank you enough for asking that question because I was really struggling with low mood and sadness almost every day.

Even though KImberley had used 5-HTP with success in the past, she was still astonished how quickly it worked and how effective it was. She was also surprised she had forgotten her prior low serotonin symptoms:

Up until January I had taken 5-HTP in the mid-afternoon and then Tryptophan at bedtime, but I wanted to try a program to support my thyroid. That program told me that too much serotonin is often at the root of gut damage, so I weaned myself off of the 5-HTP and tryptophan. I didn’t really notice much difference, except the daily sugar cravings.

I’m not sure how I could so easily forget the symptoms of low serotonin, but I did.

Your question really was a God-send for me, Trudy. It reminded me that there was an option for feeling better (in fact, MUCH better than sugar makes me feel) that didn’t involve something that’s not good for me.

And I really did feel remarkably better the same day, and those results have continued.

Thanks again, Trudy, for continuing to bring these topics up. Some of us are forgetful and need reminding. Usually, when you have symptoms of low serotonin there are enough other issues going on in your life that it’s easy to overlook the obvious. So I’m very grateful that you asked the question, because I feel so much better able to deal with my circumstances now that I’m back on the 5-HTP. Blessings to you!

I am curious about the program that told her too much serotonin is often at the root of gut damage and if they suggested stopping 5-HTP and tryptophan. It doesn’t make any sense to me. I’ll report back when I learn more about this.

More tired during the day and a headache: what to consider

She did mention “I’m finding myself more tired during the day and have also had a headache for the last few days.” I would suspect chocolate/caffeine withdrawal may have caused her headache.

With feeling more tired I’d also watch the dose of 5-HTP. She may find less is better for her needs.

She is also trying tryptophan at bedtime so that may be making her more tired the next day. Doing one amino acid at a time is often the best way to know how each one is affecting you.

Finding what works for your unique needs

Here are some other amino acid/sugar cravings blog posts that illustrate how we all have unique needs and different biochemical imbalances:

The individual amino acids glutamine, GABA, tryptophan (or 5-HTP), DPA and tyrosine are powerful for eliminating sugar cravings, often within 5 minutes

The individual amino acids glutamine, GABA, tryptophan (or 5-HTP), DPA and tyrosine are powerful for eliminating sugar cravings, often within 5 minutes. It seems that this wonderful benefit – over and above the anxiety-reducing and mood-boosting benefits – is often overlooked or poorly understood.

GABA for ending sugar cravings (and anxiety and insomnia)

For Melissa, an unexpected result was that she stopped craving sugar (chocolates, ice cream and truffles) after about a week of taking GABA for her travel anxiety.

It’s a matter of finding what works for your sugar cravings and unique needs. GABA worked for Melissa and yet 5-HTP works for Kimberley – for their sugar cravings.

Here is the tryptophan/5-HTP alcohol cravings blog that started the discussion: Tryptophan had the added benefit of turning me completely off alcohol when I took it to improve mood and sleep during perimenopause. In this case, tryptophan helped Victoria quit the wine that she was self-medicating with in order to feel good and relax.

Resources if you are new to using amino acids as supplements

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 and low endorphins).

Has 5-HTP helped reduce your cravings and/or feelings of despair and sadness? How much helps and how quickly?

Or do you find tryptophan works better for you? If yes, how much helps and how quickly?

What sugary food/s do you self-medicate with in order to feel good?

If you’re a practitioner, do you use this approach with your clients/patients?

Does 5-HTP (an amino acid) cause nightmares or does it help prevent nightmares (and also support low serotonin symptoms)?

October 7, 2022 By Trudy Scott 24 Comments

How do you do with using the amino acid 5-HTP for supporting your low serotonin symptoms of anxiety, worry, ruminating, fears, depression and insomnia? Does it help or does it cause nightmares? On a recent Facebook thread someone shared that 5-HTP causes really bad nightmares, so she had to stop using it. A few others posted saying 5-HTP also caused them nightmares. I’ve not had any clients report nightmares, so I was surprised to hear this feedback. However, most folks on the same Facebook thread shared that 5-HTP works very well for them and does not cause nightmares. There is also research that supports the use of 5-HTP for night terrors. I suspect it may have to do with low vitamin B6 and share more on that below.

Here is her experience with 5-HTP and nightmares and some of my feedback:

I don’t know how anyone takes 5-HTP. The horrific nightmares I got from taking it made me stop 50 mg. I tried 3 times thinking it was a fluke and it happened every time. Too scary for me.

My first try was suggested from my Naturopath, Metagenics SeroSyn. 200 mg. First morning waking up I had a nightmare so bad I can’t even share it. I also woke up feeling unable to wake up, drugged almost. So I waited, did more research and googled 5-HTP and nightmares just to see if there was a connection. I found it. I read to lower the dosage. So I went to Pure Encapsulations 50 mg. Same thing happened. I tried 2 more times, same thing happened. When I researched, I found so many people talking about “vivid dreams” and after my last attempt the dream was so real I thought my son was in my home when I woke up and had to process reality from my dream. That did it for me. Now I’m terrified of it. Just my own experience. I did get help from depression though! But I cannot go through one evil for another. Now I’m stuck looking for help and answers.

I thanked her for sharing and agreed it does help to do a few experiments to be sure it was the 5-HTP. I also shared that I would not consider the Metagenics SeroSyn a good 5-HTP to test because of all the other ingredients. But it also happened with Pure Encapsulations 50 mg 5-HTP – that was a good test to confirm.

I also shared that some folks do better on 5-HTP and some on tryptophan so if 5-HTP did help with low serotonin symptoms then I’d consider a trial of tryptophan especially since she did say using the 5-HTP helped with her depression.

We would also look for other ways to support serotonin – saffron, turmeric, St. John’s Wort, theanine (it supports GABA, serotonin and dopamine) and of course diet (real whole food, quality animal protein, no gluten/sugar/caffeine, fermented foods, organic vegetables and fruit, healthy fats etc), gut health and more.

I’d also look into and address low zinc and low vitamin B6 as both are needed to make serotonin and the other neurotransmitters. More on low vitamin B6, pyroluria and nightmares below.

Here is some of the feedback from other folks who also had issues with 5-HTP:

5-HTP didn’t mix well with my body either. Taken at night, horrible dreams, and 50mg Pure Encapsulations formula in the morning made me feel so dark, spaced out and terrible nausea.
I appreciate this post. I had nightmares from a magnesium supplement that included 5-HTP! Now I know I’m not alone.

And here is some of the feedback from folks who do well with 5-HTP (the majority of those who responded):

I take 100 mg of 5-HTP in the morning (Natural Factors) and about 350 mg of tryptophan before bed (Lidtke). It works well for me. No nightmares although I do dream a lot. Mostly noticed improvement in mood and ruminating thoughts. Also taking Sam-e which also helps.
I take chewable natural factors Tranquil Sleep. It contains other ingredients (like theanine) as well but it’s really easy to dose. If I take 2 it’s too much. I get weird dreams and a headache. So 1 1/2 it is.
5-htp helped me so much! But I had to take it in the morning. 250mg was perfect for me. I was using this for my debilitating anxiety which would keep me in flight or fight all day and I would ruminate. Really helped me along with therapy. I no longer need it.
I’ve just started taking 50mg 5-HTP at night. It’s a micronized version I buy from a compounding chemist in Australia. No negative side effects so far.
Grateful for the reminder … I did great on 5-htp myself. Have had all dose amounts, given at different times too. I deal with chronic pain and trauma/stress.
My sister gets anxiety on 5-HTP but it helps me so much! I have not tracked regular consumption compared to my sleep (I get too much REM without it and wake up exhausted). I also no longer need it as a daily and can take it as needed. I take 200mg, forget the brand but it’s a single ingredient.
I take 50 mg of 5-HTP from Seeking Health and do very well on it. It has helped me with depression, worry, fear, more energy and motivation and no nightmares.
I take the Now brand, 100mg at bedtime along with the same brand of L theanine. No nightmares and I’ve been doing this for about 5 years.
I use 50mg Seeking Health 5-HTP and I love it. It gives me energy and motivation, helps with intrusive thoughts and anxiety. I’ve used the Jarrow brand in the past without results. No nightmares. P5P, on the other hand, I cannot take. It gives me such clear, vivid nightmares I would wake up crying. Never again.

We are all unique and there is clearly no one-size fits all.

Low vitamin B6 can cause nightmares or poor dream recall

It’s well recognized that low vitamin B6 can cause nightmares or poor dream recall. In this study, Effects of Vitamin B6 (Pyridoxine) and a B Complex Preparation on Dreaming and Sleep (which was randomized, double-blind and placebo-controlled), 100 participants from across Australia were given 240 mg vitamin B6 (pyridoxine hydrochloride) before bed for five consecutive days. Other study participants were given a B complex. This is the outcome of the study:

vitamin B6 significantly increased the amount of dream content participants recalled but did not significantly affect dream vividness, bizarreness, or color, nor did it significantly affect other sleep-related variables
participants in the B complex group showed significantly lower self-rated sleep quality and significantly higher tiredness on waking

This vitamin B6/dream recall research is of particular interest to me because of my work with pyroluria, a social anxiety condition which responds really well to supplementation with zinc, vitamin B6 or P5P (pyridoxal-5-phosphate) or a combination of both, and a few other key nutrients. Here is the pyroluria questionnaire.

One of the classic signs of pyroluria is poor dream recall, stressful or bizarre dreams, or nightmares, signs which the late Carl Pfeiffer, MD attributed to low vitamin B6 status. He suggested that your dreams and dream recall serve as a good indicator of your need for vitamin B6. You should dream every night and you should remember your dreams. They should be pleasant – the kind of dreams where you wake up and want to close your eyes and continue dreaming.

Could it be that folks who get nightmares with 5-HTP, happen to also have pyroluria? Or perhaps they simply have low vitamin B6 status? I have all my anxious clients supplement with vitamin B6 and/or P5P and this may be why nightmares with 5-HTP was news to me.

5-HTP can increase cortisol – does this affect nightmares?

There is research and clinical evidence supporting that, for some individuals, 5-HTP can raise cortisol. I’ve blogged about this here:

This is not always the case. Someone in the same Facebook thread shared this: “My cortisol measured above the reference range, but 5-HTP is the only thing I’ve found that’s helping me sleep recently.”

I’m not aware of a high cortisol-nightmare connection but it’s possible. In one study, nightmares triggered high cortisol the next morning, but I donut this has relevance in this situation.

5-HTP induces long-term improvement of sleep terrors in children

There clearly is a subset of folks who don’t do well with 5-HTP and yet there is evidence that it can actually improve sleep terrors. In a small open label clinical trial of 45 children, it was found that 5-HTP was able to “modulate the arousal level in children and to induce a long-term improvement of sleep terrors” (in the majority of children in the trial). There were 34 male and 11 female children ranging in age from 3.2-10.6 years.

After the first visit, L -5-HTP was administered (2 mg/kg per day) at bedtime to 31 randomly selected patients for a single period of 20 consecutive days. After 1 month of treatment, 29/31 (93.5%) of patients showed a positive response. In the comparison group without drug therapy, after 1 month, the episodes disappeared only in four children (28.6%) while ten children (71.4%) showed the persistence of episodes with the same frequency as before. After 6 months, 26/31 (83.9%) of children treated with L -5HTP were sleep terror-free, while in five children (16.1%) sleep terror episodes persisted. Of the children in the comparison group, ten (71.4%) continued to show sleep terrors at 6-month follow-up.

If we assume a 10-year-old weighs, 70lb or close to 32kg, they would have been given 60mg 5-HTP (i.e. 2 mg/kg).

Typical adult dosing of 5-HTP is 50mg twice a day, mid-afternoon and evening. For a 10-year-old we may start with a quarter of this dose i.e. 12.5mg or 25mg 5-HTP twice a day, for a total of 25mg or 50mg a day – which is close to what was used in this study.

You can read more about this in the paper here: L -5-Hydroxytryptophan treatment of sleep terrors in children

Resources if you are new to using 5-HTP and other amino acids as supplements

If you are new to using any of the 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 serotonin and low GABA).

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, 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.

How do you do with 5-HTP for low mood, worry-type of low serotonin anxiety, cravings, PMS, negative self-talk, anger/rage/irritability, insomnia, ruminating thoughts, winter blues etc? Does it help?

Or does it give you nightmares that are bad enough that you have had to stop?

Please share how much you used? And if tryptophan or other serotonin support helped instead?

Did the addition of vitamin B6 or P5P help prevent the nightmares when using 5-HTP?

And do you have pyroluria or suspect you may have it? Do you have high cortisol?

If you’re a practitioner I’d love to hear your experiences with 5-HTP and nightmares.

If you have questions please share them here too.

What causes low serotonin? Use tryptophan/5-HTP to help with the anxiety, overwhelm and worry right away and address all the root causes

May 13, 2022 By Trudy Scott 40 Comments

Low serotonin has a number of root causes which can be different for each person. If you do have low serotonin levels you always want to figure and address why it’s low. This can take time to figure out and resolve so you want to be using either tryptophan or 5-HTP (and sometimes both) to boost your serotonin levels and get symptom relief quickly. This helps with the worry, overwhelm, anxiety, insomnia, carb cravings, TMJ, irritability, PMS, anger, OCD, low mood and ruminations right away. It also helps with the worry and overwhelm triggered by sometimes complex and challenging root causes.

Here is a list of some of the many factors that may cause low serotonin for you:

stress and adrenal dysfunction (high cortisol affects your sex hormone and neurotransmitter production, inlcuding serotonin)
eating junk food and sugar (a Western diet “of processed or fried foods, refined grains, sugary products, and beer was associated with a higher odds of mood disorders”
consuming caffeine (which reduces zinc and B vitamins, needed to make serotonin)
not consuming enough quality animal protein (amino acids are the building blocks of our neurotransmitters, and grass fed red meat provides zinc, iron and omega-3s – all needed to make serotonin)
low stomach acid (meaning you can’t digest the protein you’re consuming)
gluten issues (leading to low serotonin and other nutritional deficiencies such as low iron, low vitamin D etc.)
low vitamin D (“Brain serotonin is synthesized from tryptophan by tryptophan hydroxylase 2, which is activated by vitamin D hormone”)
low iron/ferritin levels (iron is a cofactor for making serotonin)
dysbiosis and microbiome imbalances (we make so much serotonin in the gut)
candida (in one study short exposure to serotonin resulted in antifungal activity)
liver issues (affecting how you process xenoestrogens)
low bile production (affecting how you digest the healthy fats you’re eating)
sex hormone imbalances (serotonin and estrogen are very closely linked and women make less serotonin than men. In one study, tryptophan improved the low serotonin PMS symptoms)
thyroid imbalance (“it is postulated that one mechanism, among others, through which exogenous thyroid hormones may exert their modulatory effects in affective illness is via an increase in serotonergic neurotransmission”)
histamine imbalances (in one study “Acute LPS-induced inflammation increases CNS histamine and decreases CNS serotonin)”
the birth control pill (which lowers zinc and vitamin B6, both of which are needed for serotonin production)
statins (leading to cholesterol that is too low)
mold exposure/mycotoxins/mold poisoning
heavy metal toxicity such as lead (and tryptophan and ascorbic acid can help ease the anxiety)
Lyme disease and other co-infections (serotonin was found to be low in cerebrospinal fluid in patients with post-Lyme disease syndrome i.e. chronic Lyme)
collagen consumption (in susceptible folks this can lower serotonin levels)
seasonal allergies (“Cytokines may lead to a mood disturbance via the expression of the IDO enzyme, which shifts the synthesis of tryptophan from serotonin to kynurenine. The resultant acute tryptophan depletion results in decreased brain serotonin”)
genetics (one example is the MTHFR polymorphism)
low zinc, low vitamin B6 (and other B vitamins), low selenium, low magnesium etc. – all needed to make serotonin
oxalates (which can bind to zinc and deplete it)
a high copper diet (nut flours on Paleo diets can be problematic), copper IUD, copper pipes etc. (which can cause low zinc)
lack of nature (forest bathing reduces cortisol which affects serotonin production)
lack of exercise
lack of sunshine (like in the winter when serotonin declines)

When I posted some of this list on Facebook earlier this week, there was a great deal of interest, hence this blog. I’ve included one relevant link for each one so you can read further on the topic.

When I posted it I also asked this: “Have you figured out your root cause/s that are contributing to your low serotonin levels? And has tryptophan or 5-HTP helped while you’re figuring it all out?”

Leanne has mold, dysbiosis, Lyme, low vitamin D, bile issues and more

Leanne responded and gave me the go ahead to share especially if this helps someone else (I appreciate that!) She shared she has identified these root causes:

Mold. Dysbiosis. Possible Lyme/co-infections. Low vitamin D. Bile and motility issues. Liver issues. Stress. Low HCL. Those are the ones I’m aware of. And taking each and every day to work on them. It takes time to heal

I agree it takes time to heal and can be a longer journey for some folks, especially when there are a number of underlying factors. She is in a good frame of mind, saying pragmatically, it takes time to heal. This confirms her serotonin levels are robust i.e. she is not in a state of overwhelm and worry. Sure enough, when I asked if tryptophan or 5-HTP has been helping this was her response:

5-HTP and GABA calm initially helped me in my first round of going through this back in 2015. Then I discovered l-tryptophan about a year ago and that seemed to be a better help over 5-HTP.

Since I’ve just identified that histamine is an issue and started a low histamine diet this past week I noticed less of a need for l-tryptophan as I did before. My body is calming down significantly. And my digestion is working a little better.

But I still have to address mold, SIBO, candida, parasites and possibly Lyme and underlying hidden viruses.

So I know these amino acids will play a key part in supporting me as I dive deeper into addressing them all.

It’s wonderful the amino acids have helped her so much and they will most likely continue to help. A quick comment on her preference for tryptophan over 5-HTP – some folks do better on one vs the other.

Regarding the histamine issues/root cause, it’s good that she is now addressing this. Already she needs less tryptophan (for now). Things may fluctuate in the future again as she peels away the onion layers of root causes. She may find she needs tryptophan again or a higher dose or needs to get back on the GABA.

As you can see she has been working on her health for some time. This is not unusual. Slow and steady is just fine, especially when there is so much going on.

The amino acids are intended for short-term use while diet and underlying root causes are addressed. But when the list is long this is a common reason for the ongoing need for serotonin support. Keep in mind, your list may be a short one and may be quick to resolve. And not everyone has the same root causes.

Resources if you are new to using tryptophan or 5-HTP as supplements

If you are new to using tryptophan or 5-HTP as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the low serotonin symptoms).

If you suspect low levels of serotonin or 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 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, blood sugar control, sugar cravings, self-medicating with alcohol and more.

Have you figured out your root cause/s that are contributing to your low serotonin levels? And does this give you a better understanding of your own issues?

Do you have any other root causes I may have missed? (when I posted this list on Facebook, a few people pointed out I had missed a few. I’ll update the list and continue to add as we discover new connections).

Has tryptophan and/or 5-HTP helped you feel less overwhelmed and worried while you’re figuring it all out?

Have you adjusted doses of tryptophan and/or 5-HTP as things change and root causes are addressed/resolved?

If you’re a practitioner, do you have anything to add and do your clients/patients find this useful?

An amino acid supplement with DLPA, glutamine and 5-HTP eases alcohol withdrawal symptoms at an inpatient detoxification program

April 8, 2022 By Trudy Scott 18 Comments

An amino acid supplement with DLPA, glutamine and 5-HTP (and a few other nutrients) eases alcohol withdrawal symptoms at an inpatient detoxification program. Other than anxiety (I’ll share more on this below), there was also a significant decrease in psychiatric symptoms. Here is an excerpt from the study, The use of a food supplementation with D-phenylalanine, L-glutamine and L-5-hydroxytriptophan in the alleviation of alcohol withdrawal symptoms:

We described the use of a food supplementation with D-phenylalanine, L-glutamine and L-5-hydroxytryptophan in the alleviation of alcohol withdrawal symptoms in patients starting a detoxification therapy.

Since abstinence from ethanol causes a hypodopaminergic and a hypoopioidergic environment in the reward system circuits, manifesting with withdrawal symptoms, food supplements that contains D-phenylalanine, a peptidase inhibitor (of opioid inactivation) and L-amino-acids (for dopamine synthesis) were used to replenish a lack in neurotransmitters and alleviate the symptoms of alcohol withdrawal.

First I cover some translation issues and then more about the actual product and study results. I also share my commentary on the amino acids and dosing used in the study (and the fact that anxiety did not resolve). I include how to apply this information if you have a loved one in an alcohol treatment/rehab program or if you recognize social drinking is an issue for you. And I wrap up with additional resources if you are new to using GABA as a supplement, the GABA Quickstart online program and the practitioner training.

The study was completed and published in Slovenia and there are a few translation issues I’d like to clarify:

The study title states D-phenylalanine (DPA) was in the amino acid product, however DL-phenylalanine (DLPA) was actually used. You can read about the difference between DPA and DLPA here. In summary, DPLA works on both dopamine and endorphin support and DPA works on endorphin support only.
As you can see from the excerpt above, hypodopaminergic refers to low dopamine and hypoopioidergic refers to low endorphins. During withdrawal from ethanol/alcohol, both low dopamine and low endorphins cause withdrawal symptoms.
L-5-hydroxytryptophan is incorrectly spelled as L-5-hydroxytriptophan and reward system is incorrectly spelled as reword system. (Clarifications are provided for facilitating online searches in the research literature.)

More about the product, the study and the conclusion

It was a small randomized, double blind study with just 20 patients and the amino acid product was used for 40 days of the inpatient alcohol detox or rehab program.

This is the actual combination product used:

300 mg DLPA

150 mg glutamine

5 mg 5-HTP

1 mg vitamin B6

50 mg calcium gluconate

25 mg magnesium oxide

0.01 mg folic acid

Psychiatric symptoms were measured using the SCL- 90R and included assessing for “somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid, and psychoticism.” During their rehab there was a significant decrease in these categories of psychiatric symptoms in the study group, except for their anxiety symptoms.

The authors conclude that “abstinence causes a major stress for the patients. The use of a food supplement containing D-phenylalanine [it was actually DL-phenylalanine], L-glutamine and L-5-hydroxytryptophan alleviates the withdrawal symptoms.”

As expected, once alcohol consumption was stopped, cortisol levels, liver enzymes and total bilirubin all decreased in the study group and the control group.

My commentary on the amino acids and dosing used in the study (and the fact that anxiety did not resolve)

Keep in mind the same dosing was used for all study participants. What I use clinically with folks with low levels of these neurotransmitters, is an individualized approach based on each person’s needs, for endorphin and dopamine support (from the DLPA), blood sugar support (from glutamine) and serotonin support (from 5-HTP). This means identifying symptoms in each category and doing a trial of each respective amino acid, starting low and increasing based on symptom resolution.

Given that anxiety symptoms didn’t resolve in the study group, I would have loved to see the amino acid GABA included, also dosed according to individual needs. GABA helps ease the physical tension-type anxiety and low GABA tension often drives the need to self-medicate with alcohol in order to relax and fit in socially.

The authors do mention GABA too: “the physiological craving for alcohol may be the result of a deficiency of the naturally occurring opiate like substances as well as other neurochemical deficits (i.e., dopaminergic, GABAergic, and serotonergic).

Also, an animal study shows that GABA helps with gut damage caused by alcohol consumption, so there is this additional benefit.

A higher dose of glutamine and/or 5-HTP may have also helped ease anxiety. They used 150 mg glutamine whereas a typical starting dose for glutamine is 500 mg (and we increase from there). Going up to 1000 mg to 1500 mg three or 4 times a day is not unusual and is typically very beneficial for alcoholics – for blood sugar stability, an additional calming effect and for healing the leaky gut which has been damaged by the alcohol consumption.

With regards to 5-HTP, they used 5 mg 5-HTP which is considered extremely low. I wonder if it was in fact 50 mg, which is a typical starting dose? Going up to 150 mg 5-HTP use 2 or 3 times a day is not unusual. Serotonin support with 5-HTP (or tryptophan) is very beneficial for the worry-type of ruminating anxiety.

For some individuals DLPA may have been too stimulating and contributing to anxiety via a dopamine boost. For these individuals, DPA may have been a better option for endorphin support.

I am not in favor of folic acid and prefer methylfolate, and although magnesium is an important cofactor for neurotransmitter production, magnesium oxide does not provide much usable magnesium.

Outside of the amino acids and other nutrients used, a vitamin B1 (thiamine) deficiency would need to be addressed and any other deficiencies (such as all the B vitamins, zinc, vitamin D, magnesium etc.) caused by chronic alcohol consumption. This is not a comprehensive list and a full functional workup will help to identify all possible deficiencies.

Despite my quibbles, the outcome of the study is very encouraging, I appreciate the researchers and I hope to see it replicated and refined in other settings.

How to apply this information if you have a loved one in an alcohol treatment/rehab program

Unfortunately the amino acids are seldom incorporated at in-patient detox and rehab centers but they should be. Your options are to:

Share this study and my blog with the treatment center
Educate yourself (on using the questionnaire and doing the amino acid trials) so you can use them with your loved one once rehab is over. This is key for preventing a relapse and for swapping alcohol addiction for sugar or caffeine or nicotine addiction.
Introduce one amino acid at a time so you can figure out which one/s they need and how much
Read my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, and share a copy with the treatment center (and your loved one and their treatment team)
Address diet, nutritional deficiencies and gut health

Keep in mind that the amino acids are used with success for cocaine, heroin and other drug addictions.

How to apply this information if you recognize social drinking is an issue for you

New research shares that “low-level alcohol consumption is commonly perceived as being inconsequential or even beneficial for overall health, with some reports suggesting that it may protect against dementia or cardiovascular risks”, however, as the authors suggest “even low-level alcohol consumption is associated with premature brain aging.”

Social drinking is the norm and is way too prevalent. And it’s often used as a calming measure in order to relax and fit in socially. If this sounds like you:

Educate yourself (on using the questionnaire and doing the amino acid trials) so you can use them to quit drinking easily with no willpower and no feelings of being deprived. This is key for preventing the swapping out the need for alcohol (to relax or fit in socially) with a sugar or caffeine or nicotine addiction. In this case, GABA helps a young man who has recently given up alcohol, Adderall and nicotine.
Introduce one amino acid at a time so you can figure out which one/s you need and how much
Read my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, and share a copy with your loved one/spouse/partner and practitioners/therapists.
Address diet, nutritional deficiencies and gut health

Resources if you are new to using the amino acids as supplement

If you are new to using the amino acids as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the low neurotransmitter symptoms).

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 team you or your loved one is working with.

There is a section on alcohol but keep in mind that all the sections on sugar craving/addiction apply to alcohol addiction and self-medicating with alcohol too. Some individuals use alcohol to numb out and some use sugar. Many use both and once alcohol addiction is addressed, it’s often replaced with sugar and caffeine addiction. This is why addressing neurotransmitter imbalances is key.

If you don’t feel comfortable reading my book and figuring things out on your own (doing the symptoms questionnaire and doing respective trials), you can get guidance from me in the GABA Quickstart Program (online/virtual).

If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. It’s an opportunity to interact with me and other practitioners who are also using the amino acids.

Have you used amino acids with success as part of an alcohol detox program (for yourself or for a loved one)? Or to help stop social drinking of alcohol?

Which neurotransmitter imbalances were driving your need to self-medicate with alcohol and which amino acids helped?

If you’re a practitioner do you use the amino acids (via an individualized approach) to help with alcohol withdrawal and cessation with your patients and/or clients?

Feel free to ask your questions here too.
