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.
Additional resources when you are new to using tryptophan and GABA and other amino acids as supplements
As always, I use the symptoms questionnaire to figure out if low serotonin or low GABA or other neurotransmitter imbalances may be an issue.
If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.
There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control (this is covered in an entire chapter too), sugar cravings, anxiety and mood issues.
The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs.
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.
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.

First off, thank you for all you do. The information you share is incredibly helpful!
I was wondering if you are familiar with transdermal GABA? I just listened to an interview with Dr. Marco Ruggiero and he says that GABA doesn’t really do anythiing if taken by mouth. He has a new cream that contains GABA (as well as probiotics and chondroitin sulfate). Your thoughts?
Nilou
You are most welcome!
I am very familiar with GABA cream and have recommended Somnium to my community for a number of years. This is the product Dr. Ruggiero created with Dr. Christine Schaffner and is the precursor to this new Bravo product he discusses.
Here is a blog link to Somnium GABA cream the https://www.everywomanover29.com/blog/somnium-nighttime-gaba-cream-insomnia-anxiety-bloated-belly-muscle-spasms-ms-arfid-anorexia-alzheimers-and-autism/ – as you can see there are great applications and I have many folks in my GABA program report great results.
I deleted the link to the video because it requires an optin to watch – but I did watch because I wanted to know if this was current info. I appreciate you for sharing it.
On the one hand it surprised me to hear him say oral GABA doesn’t work but Dr. Schaffner (whose work I regard highly) says the same thing so now I know where it’s coming from. He is correct in that GABA swallowed doesn’t seem to work but I respectfully disagree and we have a professional difference of opinion. GABA DOES works when used sublingually and held on the tongue for 1-2 mins, low dose and increasing to find the ideal dose.
I plan to reach out to him to share my low dose sublingual approach and find out more about the new GABA cream for my community.
Hi Trudy!
I would like to start using the amino acids. I have OCD that started about 6 months ago related to a trauma response (my father passing). I am still trying to get a hold of it all. My PCP and psychiatrist wants to put me right on meds but I am very holistic and not OK with that. Thankfully I found your blog and book!
I have read through it and would like to start with low serotonin although I resonate with both low serotonin and GABA. But it sound like low serotonin is more closely linked to OCD (plus inositol). I tried tryptophan Lidtke 500mg cap opened on my tongue (I did only use 1/2; so about 250) and did not feel any affect. Maybe a bit of an upset stomach but no relief. However later in the evening my OCD got worse (not sure if there is a correlation as it was about 6 hours later). So I have not tried is again. I did get 5-htp and have tried that twice now. My local store had the Natrol Brand 50 mg. I opened and did about 2/3 of the cap on the tongue and did not feel any relief but possibly a slight headache for about 30 minutes after. The next day I did try taking the entire capsule however I just swallowed it. Again no change. I am assuming it would be worth trying them both again with the full dosage you recommend and opened on the tongue? In all my reading it seems relief should be felt within 5-30 minutes feeling “relaxed as though I had a glass of wine”. If I do the 50mg 5-htp or the 500mg tryptophan and feel nothing within 30 minutes can I try making more to see if I just need a higher dose? Of course only choosing one of those at a time but can you add to it very closely like that to find the right dose to start with?
I also was able to find the Carlson Brand 50 mg sublingual 5-htp locally. I know brand matters so could it just be that as well? I have read where you said some clients go through multiple brands to find the right one that works. I may just order the pure encapsulations but I was waiting to see if either of these had any effect before I spent more money.
Or could the problem lie in the fact that maybe it is GABA vs serotonin??? I was able to find the Natural Factors PharmaGABA chewable (I know this was a stand by option but my local health store had it in stock). I have not tried this yet. Am I able to try a trial of let’s say 5-htp and GABA in the same day? Since I truly am not sure what I need.
Thank you so much. I am so looking forward to finding some relief from all this. I also got the DFH inositol powder to add in as well!
Nicole
Too much tryptophan can cause opposite effects and some do better on 5-HTP. We also do an initial one-off trial to see if other low serotonin symptoms improve or get worse with whatever dose we use. And we methodically trial increasing and/or decreasing either tryptophan or 5-HTP and then the other before adding in GABA support.
Hi Trudy,
I know you recommend the Lidke Tryptophan but I wondered what you thought of this complex?
My 15 year old daughter has depression and I thought it covered alot of the cofactors needed to make serotonin, though its quite expensive.

I would pick Lidtke Tryptophan Complete over this product simply because it’s a proprietary formulation and we don’t know how much safron and 5-HTP it contains. However I would start with Lidtke 500mg tryptophan to find the ideal dose and then consider adding Lidtke Tryptophan Complete or switching to it.
I’d also be looking into low dopamine depression and all the dietary factors covered in my book “The Antianxiety Food Solution”
And if you need guidance and support the Serotonin Quickstart program is a great option
I previously bought Lidtke Tryptophan on Amazon 7 times, always in a glass bottle, and always with a very bitter taste. This time, they delivered an obviously fake product: a plastic bottle and only very slightly bitter. It seems that most of the pill consists of chalk or something similar. Where to buy original Lidtke Tryptophan?
Lili
Best to reach out to Lidtke directly about this and check if they ship via Amazon in your country. But it really is best to avoid purchasing supplements on Amazon.
I do know they have now switched to a white plastic bottle instead of the dark glass one. The product is the same quality and as effective. My question for you, is this product your purchased as effective as the product in the glass bottle?
For US customers it’s available in my Fullscript store and for other countries it can be purchased directly from Lidtke, although I’m aware there are now some shipping restrictions to certain countries like Australia.
