Theanine for easing stress and anxiety, and improving cognition and sleep in healthy adults

January 24, 2020 By Trudy Scott 46 Comments

L-Theanine is a “unique non-protein amino acid found in green tea” which according to the study below, has shown benefits when used short-term or acutely as a supplement for it’s anti-stress effects, reducing anxiety, improving sleep quality, improving cognition and even easing depression.

This 2019 study, Effects of L-Theanine Administration on Stress-Related Symptoms and Cognitive Functions in Healthy Adults: A Randomized Controlled Trial, aimed to examine the effects of four weeks use of l-theanine:

on stress-related symptoms and cognitive functions in healthy adults. Participants were 30 individuals (nine men and 21 women; aged 20-69) who had no major psychiatric illness.

The trial was randomized, placebo-controlled, crossover, and double-blind.

L-theanine (200 mg/day of Suntheanine), was used by study participants before going to bed each night and was used for four-weeks.

Study participants who used the theanine for two weeks observed the following:

For sleep: Reductions in sleep latency (the amount of time it takes to fall asleep), sleep disturbance and less use of sleep medication
For cognitive function: Improvements in verbal fluency (especially letter fluency) and improvements in executive function (planning, multi-tasking etc)

The Japanese versions of The Self-rating Depression Scale, State-Trait Anxiety Inventory-trait, and Pittsburgh Sleep Quality Index (PSQI) scores decreased and the study concludes as follows:

Our findings suggest that L-theanine has the potential to promote mental health in the general population with stress-related ailments and cognitive impairments.

The authors also note that “there were no significant adverse events, demonstrating the safety of four weeks of L-theanine administration.”

As expected, the participants saw increases in serum theanine concentrations.

Some of the reported possible mechanisms of action

Here are some of the reported possible mechanisms of action of theanine from some studies referenced in his paper:

via glutamate receptors (improving cognitive dysfunction)
as a neuroprotective agent and “increases in brain serotonin, dopamine, GABA levels” (improving mood and focus and reducing anxiety)
enhances hippocampal activity (the hippocampus has a major role in learning and memory)
via a proposed increase in the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus (BDNF is a protein implicated in the stress response, long-term memory, Alzheimer’s disease, and psychiatric disorders)

Impacts on cortisol levels?

What is unusual and inconsistent with previous studies, is the fact that there was “no significant effect on cortisol or immunoglobulin A levels in the saliva or serum.” The authors report that “the reduction of salivary cortisol and immunoglobulin A levels may be a short term, recoverable effect of L-theanine administration.”

Update Sept 2025:

In this 2021 paper, A Randomized, Triple-Blind, Placebo-Controlled, Crossover Study to Investigate the Efficacy of a Single Dose of AlphaWave®l-Theanine on Stress in a Healthy Adult Population “there was a significant reduction in salivary cortisol with a single dose of AlphaWave® l-Theanine relative to the placebo, immediately following the stress-inducing task 1 h post-dose.”

In other words, within an hour of taking AlphaWave l-theanine, cortisol levels were lower. This paper also mentions that in a previous study, cortisol levels were only lower 3 hours after taking theanine.

Suntheanine and AlphaWave are different theanine products, each produced by their own proprietary manufacturing process. There are a number of other l-theanine products/manufacturing processes and this may explain why some individuals do well on some theanine products and not others, and why impacts on cortisol levels may vary.

Theanine or GABA – which one to use when?

I typically start my clients with a trial of GABA Calm for low GABA symptoms like physical tension, stress and overwhelm, panic attacks and insomnia. If we are not getting all the expected benefits with GABA and there is a need for added cognitive benefits then we’ll consider adding theanine too. Some folks find one works better than the other and some like a combination (at the same time or theanine in the day/GABA at night or GABA in the day/theanine at night).

I recently reached out on facebook asking:

“Theanine or GABA? Which do you prefer for anxiety and why? How much helps? And any other benefits (like reduced body pain, better thinking/cognition, easing IBS (irritable bowel syndrome) and gut pain, reduced cravings, less negative self-talk etc)? Or do you like a combination of both?”

As you can see from these varied responses it’s a matter or trialing both to find what works for each person’s unique needs:

Lorraine shared this: “They are both good, but I reach for GABA Calm first.. 2 or 3 lozenges. If anxiety doesn’t leave quickly with GABA ( which works well for a panic attack), and I continue to have anxiety humming along in the background, then I’ll reach for theanine.”
Jackie shared this: “I take 200mg theanine in morning, then 100mg GABA around 4pm, when the kids get home from school. I had a panic attack in the middle of the night last week, took GABA 100 mg, then seemed to calm down.” I asked if theanine gives her a feeling of calm focus and she said: “yes, I think so. I noticed if I take 200mg of GABA, it makes me drowsy.”
Evelyn shared this: “I use both at night for sleep. If I could only use one it would be l-theanine.” Theanine is more consistently helpful for stress reduction and sleep for me. I use 200mg. When I use GABA it’s 500mg of chewables.”
Sara shared this: “GABA during the day, theanine at night.”
Karine shared this: “GABA!! The Source Naturals Theanine Serene with Holy Basil is really good. But GABA Calm (also Source Naturals which is a sublingual lozenge) is the only thing for a severe issue/episode and helps me concentrate right before an important presentation at work etc. Pure GABA from any supplier is good for long periods where you need a boost or to tone down general anxiety. I also bought a probiotic that also includes GABA (Jarrodophilus Mood) and notice it improves digestion too.”

Some of my top GABA/theanine products

You can find my favorite GABA/theanine combination product, a theanine-only product and my most popular GABA products on the supplements blog here (and with details for how to set up an account for my online store)

Nutritional Fundamentals for Health GABA-T SAP: 300mg GABA, 150mg theanine. This is pleasant-tasting when opened on to the tongue and works very well when GABA Calm can’t be used.

Pure Encapsulations L-Theanine: 200mg theanine. This is also pleasant-tasting when opened on to the tongue. Unlike like GABA, it can also be swallowed.

Source Naturals GABA Calm. This is a pleasant-tasting sublingual product that is my most popular and most effective form of GABA I use with my clients. It can be used in conjunction with theanine.

Enzymatic Therapy GABA: 250 mg GABA. This is also pleasant-tasting when opened on to the tongue and works very well when GABA Calm can’t be used. It can also be used in conjunction with theanine.

BeSerene IR (instant relief): a topical GABA/theanine cream which can be used in conjunction with other GABA and theanine products or instead of them.

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

We use the symptoms questionnaire to figure out if low serotonin or low GABA or low dopamine 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.

Now I’d love to hear from you

Please let us know … theanine or GABA: which do you prefer for anxiety and why? How much helps? And any other benefits (like reduced body pain, better thinking/cognition, easing IBS gut pain, reduced cravings, less negative self-talk etc)? Or do you like a combination of both?”

When using GABA for anxiety does tolerance increase and which amino acid to use for a low mood?

May 31, 2019 By Trudy Scott 4 Comments

Today I’m sharing some great questions I’ve received about GABA and serotonin support for anxiety and low mood, and my feedback to give you some ideas on what to look for as you use the amino acids for your own issues (or with clients/patients if you’re a practitioner).

I cover possible reasons for ongoing low GABA levels, long-term use of the amino acids, low mood associated with menopause, problems with mainly sugar- and gluten-free, the role of the adrenals and thyroid, the amino acids I’d start with for low mood, how lithium orotate may help, how to know if collagen is causing a low mood and making you more anxious, and some resources for you.

GABA tolerance has increased

Gaba has been a lifesaver for my anxiety! I also use taurine sometimes for anxiety too, and that has helped too. Right now, I take 1000 mg [of taurine]. As for GABA (I now take 1000 mg of that also) I have noticed that my tolerance for it has increased.

Here is my feedback: I’m really pleased GABA and taurine are helping ease your anxiety. I have not seen tolerance to be a factor with my clients using GABA and I’m not aware of any research on this topic. I would look into what could be depleting GABA at a faster rate so you seem to need more and more.

This could be caused by:

increased stress which lowers zinc and increases cortisol
poor gut health and dysbiosis (there is a bacteria in the gut that may consume GABA – it’s called gabavorous)
low zinc and low B6 (which are needed to make GABA and other neurotransmitters)
toxin exposure (we’re now seeing that GABA has a protective effect – this blog covers have GABA is protective of the thyroid after fluoride exposure)
thyroid problems (the amino acids are less effective in this instance)

Keep in mind that long-term use of the amino acids is not the plan. Once the diet is addressed and the other underlying biochemistry, nutrient deficiencies, toxins etc. are addressed they should no longer be needed. At most, an occasional “top-up” may be needed.

Low mood associated with menopause

Which amino acids would you recommend for low mood associated with menopause? No panic attacks but a crashing low mood for 24hrs or more before slight recovery, a few easy days and then the cycle begins again. Diet is mainly sugar- and gluten-free. Any suggestions would be appreciated, thank you

Here is my feedback: When I hear “diet is mainly sugar- and gluten-free” with mood swings I always look into gluten exposure and blood sugar dips. Keeping a food mood log is an easy first step to see if the low mood is tied to what is being eaten and when.

I would recommend the complete removal of gluten and sugar. Gluten can trigger depression, anxiety, OCD and lead to many psychiatric symptoms. Blood sugar swings can cause both depression and anxiety. The amino acids make it easy to quite sugar and gluten – no willpower required and no feelings of deprivation. Do the questionnaire and do a trial of the amino acids that apply. Based on the above symptoms I’d suspect tryptophan and tyrosine may help and are always a good first step while everything else is being figured out.

I would also look at adrenal function as they take up the slack in menopause and rule out Hashimoto’s thyroiditis and Graves (as you can get mood swings with both as the thyroid levels shift).

Low lithium can also cause mood swings too and lithium orotate can help to keep an even mood, allowing the amino acids to be more effective.

Finally, I’d want to know if collagen, gelatin or bone broths have recently been added to your diet and are being consumed in an on-an-off pattern that correlates with the low mood. Certain susceptible individuals find that it lowers serotonin and increases depression and anxiety, and causes insomnia.

Next steps are a full workup looking at sex hormones, low zinc, low B6, low magnesium, the gut, EMFs, sleep and other dietary factors like salicylates, histamine, glutamates etc. We look at all the possible 60+ nutritional and biochemical root causes and address them or rule them out.

It’s also important to have a good support system in place for those very low days – friends and family members, being part of a community and even keeping a mental health support line number close at hand.

And of course, I always say this: get out in nature, get some exercise, hug someone and have a good laugh.

Resources for you

My book The Antianxiety Food Solution (my Amazon affiliate link) has an entire chapter on the amino acids GABA, tryptophan, tyrosine, and DPA (and how to use them), a chapter on blood sugar balancing and glutamine and a chapter on gluten issues (and much more).

How best to use the amino acid DPA for easing heart-ache, weepiness, comfort eating and a compulsive desire for food

May 17, 2019 By Trudy Scott 37 Comments

DPA (d-phenylalanine) is an amino acid that destroys the enzyme that breaks down endorphins. Endorphins are feel-good chemicals that you experience with an endorphin rush when you go for a run or when someone gives you a big hug, when you show kindness to someone or an individual does something nice for you.

Taking the amino acid, DPA, as a supplement helps to raise your endorphins and helps when you feel weepy and overly emotional AND reduces the need to self-medicate with treats as a reward or for comfort. This amino acid is a favorite with so many of my clients and community because it makes them feel so lovely.

My recommendation has always been to chew the DPA capsule for the best effects and to get results quickly (in 2-5 minutes) but I’ve now changed my recommendation. Instead of chewing the whole capsule I now recommend opening the capsule into your mouth.

New DPA recommendation – open the capsule instead of chewing it

I’ve updated the Antianxiety Food Solution Amino Acid and Pyroluria Supplements blog as follows:

I used to recommend simply chewing the capsule to get the quickest and best effects and this worked well when it was produced in a gelatin capsule. Now it’s made with a cellulose capsule and chewing doesn’t work at all well, so opening the capsule (or just biting off the top) and tipping the powder into your mouth works best.

When it was in a gelatin capsule, the warmth of the mouth dissolved the gelatin and you could eat the capsule together with the DPA. With the cellulose capsule, chewing it leas to much of the DPA getting partially stuck in the chewed capsule, which is not very pleasant to chew and swallow. The DPA is simply much more palatable and effective when it’s opened up into the mouth, rather than chewed. There is one caveat – the taste of the DPA itself – but if you’ve been chewing it you’ll be fine opening the capsule going forward.

My favorite DPA product is Lidtke Endorphigen. It contains 500mg and a tiny amount of vitamin B2 and vitamin B6.

You’ll notice the bottle says: “Maintain healthy endorphin levels to ease minor pain.” Physical pain relief is one of the side-benefits of DPA, but you could easily replace this statement.

Results for weepiness and a deep heart-ache, and the taste of DPA

Missy shares how DPA helps her deep heart-ache sort of feeling:

I have found I was using this product incorrectly. If you are feeling fine, you do not feel much of anything from it. But today I was weepy and felt that deep, heart-ache sort of feeling. I chewed 1000 mgs (2 capsules) and it DID help lift that awful feeling within 15 minutes.

Notice that she said if you’re feeling fine you don’t feel much at all. This is true of all the amino acids – they only make a difference when you need them.

Missy chewed the capsule but with the new cellulose capsule it’s much more palatable when it’s opened up into the mouth. She also reported what about half my clients say:

Tastes like slightly bitter dark chocolate. 🙂

The remainder of my clients don’t like the taste at all, although many say the taste grows on them. I’ve always been in the dark chocolate camp and find it quite pleasant tasting.

If you have a really hard time with the taste of the DPA, you can mix it with a small amount of GABA powder (assuming low GABA is also an issue) or inositol powder (if low serotonin and obsessions and ruminations are also an issue) as both of these are naturally quite sweet.

Results for a compulsive desire for food

Nanner finds that opening a capsule into her mouth gets rid of the compulsive desire for food:

It really helps! Whenever I notice I am opening cupboards when I cannot possibly be really hungry, I open one capsule and pour it into my mouth, let it dissolve. I like the taste! The compulsive desire for food goes away, and I am able to re-focus my attention and get on with my day. Amazing! Now, I just need to form a new habit and remember to DO IT!!! Lol

Take note how quickly this works for her. She is actually opening cupboards and on the prowl for a treat or reward, recognizes this and has some DPA and viola, she no longer needs the sweet comfort she was seeking. In an ideal world she would be taking DPA a few times a day until she has good levels of endorphins. In this instance there would be no cupboard prowling. But as you can see, it can be used on-demand with excellent results.

DPA, glutamine, GABA, tryptophan (or 5-HTP) and tyrosine are ALL powerful for eliminating sugar cravings – is it low endorphins?

The individual amino acids DPA, glutamine, GABA, tryptophan (or 5-HTP) and tyrosine are ALL 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.

If you’re not certain if your cravings are comfort/reward cravings the best way to figure it which neurotransmitter deficiency is affecting your sugar cravings is to do the amino acid mood questionnaire and also review the list on this blog for further clarification: The individual amino acids glutamine, GABA, tryptophan (or 5-HTP), DPA and tyrosine are powerful for eliminating sugar cravings, often within 5 minutes

The big clue with low endorphins is that you may also feel weepy, overly emotional and sometimes experience physical pain. The emotional connection to the treat – be it chocolate or ice-cream or cookies – feels very real and very strong too and you can’t imagine having to give up this treat you clearly deserve.

Resources for you related to this blog

Here is one paper, which discusses how DPA inhibits or breaks down enkephalins (endorphins are closely related compounds) and as a result helps with depression and pain, and acts as an anti-inflammatory. This paper, discusses beta-endorphins and the reward mechanism and how they can induce euphoria, reduce pain and ease addictions and distress. Despite that fact that this is discussed in the context of drugs and alcohol, more and more research is showing parallels between drug and food cravings.

Here is the amino acid questionnaire

You can find the DPA and other amino acid products I use with my clients here.

As always, thanks for sharing your feedback and questions on my facebook page and in all the blog comments. It allows me to write blogs like this and share your own feedback and experiences.

I have to say that I agree with Sandra’s sentiments and so do most of my clients:

Honestly I think the whole world needs this!

Do let us know if DPA has helped you with reducing weepiness, comfort/reward eating?

Has it also helped with easing physical pain too?

And have you noticed DPA works best when opened up onto your tongue? And are you in the dark chocolate camp and find it quite pleasant tasting?

The amino acids GABA and tryptophan can help to relieve anxiety in children: an interview with Dr. Nicole Beurkens

December 14, 2018 By Trudy Scott 16 Comments

Using individual amino acids such as GABA and tryptophan can have an incredible impact on children with anxiety, easing anxiety very quickly. I don’t often write or talk about using amino acids with children and since many of you have asked for more resources for children, today I’m sharing an interview I recently did on this topic on The Better Behavior Show. This is a podcast hosted by my colleague and good friend Dr. Nicole Beurkens.

I share specifics on how Amino acids can help to relieve anxiety in children, together with some case studies.

Dr. Nicole sums up the power of the amino acids beautifully – and this is exactly why my clients love them so much – they take the edge off quickly, provide results and help with overwhelm:

I think that the fact that these [amino acids] can work quickly is really helpful. And as you said, it helps to take the edge off, it helps to reduce the symptoms so then we can more effectively address all of the underlying things. Because often, I’ll have parents say, “Oh, you want me to change the diet and do all these things, I just feel so overwhelmed, my kid is having so many issues, I don’t know how we’re going to do any of that.” And then when you can use things like targeted aminos to help take the edge off the symptoms for the parent and the child, it makes all of that other stuff more doable, I think.

Here are some snippets from one of the stories I share – the wonderful results I had with a 11-year old girl who had been adopted, was diagnosed with reactive attachment disorder and had explosive anger issues. This young girl:

….also had insomnia, so she was not sleeping well at all. She was very fatigued in the day, had really bad anxiety about going to school and loved colored candies and she was a big bread eater.

This family didn’t have much money to spend so I really had to find an affordable solution with the biggest benefits. She was anemic so we addressed that with iron supplements and getting her eating quality grass-fed red meat again and we figured out that gluten was an issue so she went gluten-free and this made a big difference with the outbursts.

The other factor was to figure out if low serotonin was a factor and address this. The big clues were the anger, the insomnia, the anxiety and the sugary cravings:

I was talking to her about the fact that she loved candies and she loved bread, and I said — how would you feel about giving it up? She was fuming with me. She was in a swivel chair and she turned her back to me and she didn’t want to talk about it.

I offered her a 100mg chewable tryptophan to see if it would help with her sugar cravings and the fact that she was furious with me:

“How about trying this amino acid, it’s called tryptophan and it’s chewable and it doesn’t taste bad… and then we’ll talk a little bit later. Don’t worry about what I said earlier.” So I gave her 100mg of chewable tryptophan.

She chewed the tryptophan and within 5 minutes, she turned around, smiled at me and said, “I think I can do it, I’m ready to do it.”

She was calm and smiling, and ready to give up the candies and bread and other gluten-containing products. These 3 interventions – addressing her low iron levels, having her go gluten-free and supplementing with tryptophan – completely turned this little girl’s life around.

Here is the link to the entire transcript of our interview: Amino acids can help to relieve anxiety in children. You can also find the audio interview at this same link or by going directly to iTunes – simply search for “The Better Behavior Show.”

Do listen in and/or read the transcript and learn more about:

how I do a trial of the amino acids (this allows for quick results in 5-10 minutes)
how I’ve worked with non-verbal children
a simple trick for using the unpleasant tasting tryptophan sublingually
what low GABA anxiety looks like in a child
why ADHD symptoms in children may actually be anxiety (I share another success story in this section)
why I use GABA Calm with children and adults (Dr. Nicole uses this GABA product too and loves that it’s sublingual and tastes great)
times you may consider using tyrosine or DPA
and much more

It was a pleasure to be on the show of someone whose work I deeply respect. Dr. Nicole is a unique combination of clinical psychologist, nutritionist, and special education teacher, and shares these resources for help with improving your child’s behavior naturally: her book Life Will Get Better, blog, and the Better Behavior Naturally Parent Program. and tune in to my interview and some of the other excellent interviews.

If you’d like to learn more about these supplements, look at my supplements blog here

There is also a “Liquid and powder options for children” section on this blog – with other products you may find useful for children.

I’d also like offer a caution about the 100mg chewable tryptophan This chewable form is both good and bad. It’s good because it’s a nice 100mg of tryptophan per tablet, is chewable, tastes good and is suitable for children and “pixie dust” individuals who need a very small amount and for when doing the initial trial. The bad aspect is that it does contain sugar and is quite sweet. Because you are continually consuming something sweet you may end up over-consuming them if sugar addiction is your issue. I’ve seen the same with children who want to eat them like candy. So, what I do most of the time is use the chewable tryptophan for the trial and then switch to the 500mg tryptophan after that. We did that with the 11-year old with anger issues, anxiety and candy cravings.

One more thing: Lidtke is the only brand of tryptophan I use and recommend because of its quality. I forgot to mention that in our interview.

Have you benefited from using any of the amino acids and then found they also help your child/children?

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

November 30, 2018 By Trudy Scott 30 Comments

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.

I recently posted this on Facebook: GABA for ending sugar cravings (and anxiety and insomnia) and I’m writing this blog today because it’s clear there is some confusion about this cravings aspect.

Let me first recap Melissa’s experience with Source Naturals GABA Calm during her family holiday trip (the link above has all the details):

I’m glad I bought it before traveling 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! I notice a general calmness and am sleeping well.

As well as the calming benefits of GABA, Melissa found this unexpected reduction in cravings for sweets, chocolates, truffles and ice cream after about a week of taking it:

I didn’t even realize this until I was grocery shopping and out of habit walked towards the ice cream – I stopped and realized I didn’t want ice cream. So I walked toward the chocolate – same reaction. For once in my life, I was not craving sweets. I made truffles for a NYE party and only ate two. But what is really shocking is that the leftovers are still in my refrigerator two days later and I haven’t touched them.

This is a very typical response that I see with my clients and when I shared the above blog, others on Facebook shared similar experiences and surprise about the connections. Kim found it fascinating and very timely saying:

I ran out of GABA a month ago. Not only has my anxiety been very difficult to manage but literally I haven’t been able to stop eating. Sugary, high carb, total junk has consumed my thoughts. I never realized the correlation.

April also seemed surprised to learn that GABA was also actually helping with her sugar cravings too:

I think my sugar cravings are down (not looking for something sweet every night after dinner, maybe I treat myself to once a week and not overindulge when I do) and when I think about it, I’ve lost a bit of weight as a result. Most of all it helps me sleep and reduces tension in my neck.

In the above examples, due to low GABA levels in these women, GABA was helped with both the anxiety and the stress-eating, leading to a calming effect and reduced sugar cravings. If you have low blood sugar cravings then glutamine is the amino acid to use; low serotonin cravings then tryptophan or 5-HTP will help; low endorphin cravings then DPA will do the trick; and low catecholamines then tyrosine is the amino acid to use.

The best way to figure it which neurotransmitter deficiency is affecting your sugar cravings

The best way to figure it which neurotransmitter deficiency is affecting your sugar cravings is to do the amino acid mood questionnaire and also review this list for further clarification:

If you have to eat sugar when you haven’t eaten in awhile it’s likely low blood sugar and glutamine on the tongue stops the sugar desire almost immediately and also helps with the low blood sugar symptoms of shakiness and irritability
If you stress-eat your sugar cravings are likely due to low GABA, and GABA will stop the stress-eating and calm you down
If you eat sugar or carbs to feel happy (and especially from late afternoon into the evening) then your sugar cravings are likely due to low serotonin, and tryptophan (or 5-HTP) stops the cravings and boosts mood and reduces anxiety
If you are a comfort-eater then it’s likely due to low endorphins and DPA will stop that feeling of “I deserve-it” kind of reward-eating or comfort-eating and also give you a hug-like mood boost
If you eat sugar for an energy boost or to give your focus then it’s likely due to low catecholamines and tyrosine will stop those cravings and give you a mood and energy boost, and help with mental clarity

It’s not uncommon for my anxious clients to have issues in all these areas and I have them address low blood sugar and each neurotransmitter deficiency one by one (for 2 through 5) and very methodically so they know exactly which areas are problematic for them.

When it comes to low blood sugar, addressing adrenal health is also key. And as always, we need to be making dietary changes, fixing gut health, addressing other deficiencies, removing toxins and more, using a complete functional medicine approach.

How quickly can you expect to get results?

However, using the amino acids in a targeted way like this gets you results quickly while you’re figuring out everything else.

You may say “what exactly do you mean by quickly”? When opened onto the tongue and used with the trial method, based on your unique needs, if you have low levels, you can expect to notice effects in as quickly as 5 minutes and sometimes up to 15 minutes in some cases! This is why I like to refer to them as the amazing amino acids! They truly are amazing for eliminating cravings, reducing anxiety and improving mood and even sleep – provided they are needed.

Each of the individual amino acids

Last year I wrote a series of blog posts on each of the above-mentioned amino acids. If you missed them you may find them helpful for getting a better understanding, even though they are not specific about sugar cravings:

You can find the amino acid supplements that I use with my clients here.

The amino acids help you make dietary changes with ease

Keep in mind the amino acids are intended for relatively short-term use so the goal is to work on your diet, gut health, adrenals, nutritional deficiencies etc. so they are no longer needed or only needed in times of added stress. My book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings (my Amazon link), covers in-depth how to implement much of what is mentioned in the above article: a real food Mediterranean diet, red meat, oily fish, the importance of zinc, vitamin D, antioxidants and so on, and the powerful role of nutrition in immunity, inflammation, sleep, stress, anxiety and food cravings.

The amino acids help you make those dietary changes with ease, end your cravings and stress-eating or excessive drinking, so no will power is needed and you don’t feel deprived.

Pandemic stress pushed people toward overeating, mostly looking for sugary “comfort foods”

(UPDATE 4/17/2020 for coronavirus pandemic)

Keep in mind that in times of added stress – like being in the midst of a pandemic such as the coronavirus – you may find your sugar and carbohydrate cravings have increased, and you may be over-indulging, emotional-eating, comfort-eating and/or stress-eating as a way to self-medicate in order to feel calm and good.

This paper, Nutritional recommendations for CoVID-19 quarantine, published just a few days ago, shares how continuously hearing or reading about the pandemic without a break can be stressful and may be

pushing people toward overeating, mostly looking for sugary “comfort foods”. This desire to consume a specific kind of food is defined as “food craving”, which is a multidimensional concept including emotional (intense desire to eat), behavioral (seeking food), cognitive (thoughts about food), and physiological (salivation) processes.

We can apply this knowledge and logic to any stressful situation we may find ourselves experiencing.

Self-medication with alcohol as a way to calm down

You may also find you are more drawn to alcohol as a way to calm down and relax i.e. self-medication with alcohol. According to this Forbes article, Nielsen reports that online sales of alcohol increased by 291% compared to the end of March 2019.

You may be surprised to learn that the amino acids also help with reducing alcohol cravings and the need to self-medicate with this “drug-of-choice.” If one glass of wine leads finishing to an entire bottle in one evening or if you’re drinking beer or spirits excessively, know that the words “sweets”, “sugar”, “carbs” can be substituted in the blog post below with “alcohol” and consider trials of the respective amino acids.

This blog post illustrates this perfectly: Tryptophan had the added benefit of turning me completely off alcohol when I took it to improve mood and sleep during perimenopause.

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).

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, anxiety and mood issues.

Have you found any of the amino acids to help you eliminate your cravings for sweets, chocolate, ice-cream and other high-carb foods? Were you pleasantly surprised to experience this lovely benefit when you were initially looking for anxiety-relief?

Were you / are you drinking more and have you figured out which amino acids help you quit?

If you’re a practitioner, do you see similar cravings benefits with your anxious clients/patients?

Are you still struggling with comfort-eating, stress-eating of carb/sugar or drinking alcohol to “self-medicate” and feel better?

Using amino acids for anxiety and depression: does the right dose ever change or need a tweak?

October 19, 2018 By Trudy Scott 14 Comments

If you are using targeted individual amino acids for anxiety and/or depression and doing well on them, you’ll likely get to the point when you’re asking questions like how to discontinue them and does the right dose ever change or need a tweak, especially after some stressful life events. Amy posted this question in the comments section of the blog on using tyrosine to create a sense of calm energy (paraphrased and formatting for ease of reading)

Trudy you are a God send! I stumbled upon your work after following Julia Ross. I have depression and anxiety. I’m currently taking:

1000 mg tyrosine 2x daily

500 mg glutamine morning, 1000mg mid-morning and afternoon

500mg DPA (Endorphigen) 3 x daily (previously I was using DLPA but your recommended DPA was so much better and less stimulating)

50 mg 5-HTP afternoon and

1500mg tryptophan at night

I used the amino acids to treat what used to be referred to as “atypical” depression: loss of motivation, tiredness, lethargic, intense carb craving, feelings of guilt and hopelessness. I would become paralyzed with depression, barely able to get through the days. When I was younger I treated these episodes with antidepressants but as I got older could no longer tolerate the side effects. I’m also still on birth control pills at the age of 46 and believe I may be in perimenopause but can’t stop the pills for medical reasons.

Tyrosine gave me my energy back, glutamine cut the carb cravings. DPA and True Calm work wonders for my anxiety.

I watch my sugar intake and always consume lots of animal protein. I’m so grateful for this solution.

After trialing this seems to be the right combo. I always get confused when is it time to discontinue supplements? Do you stop or slowly reduce or taper?

Does the “right” dose ever change? I’ve been on this combo about 2 months. I’ve felt great but some anxiety/panic creeping back up …. wondering if supplements need a tweak or is this just the result of some stressful life events. Advice appreciated!

I was really pleased to hear the wonderful results she was having and glad that she had trialed the amino acids to find the correct amount for her unique needs and situation. I don’t see this happening often enough and it really is the most effective way to get results. It’s what I do with all my clients – methodical, step-by-step trialing of each amino acid, one at a time and carefully documenting results (both good and bad) in order to find the optimal dose of each one.

When and how to discontinue the amino acids?

To answer her question about when and how to discontinue this is my feedback:

Once you are feeling back to your old self with no more anxiety, panic attacks or depression, you may choose to stop everything at once, but I prefer to slowly lower the amount of one amino acid at a time and add back if your symptoms come back. They don’t need to be “tapered” but doing it this way it helps with preventing your original anxiety and depression symptoms going back to really bad in one big swoop and having to start all over again.

I will add that I have had feedback from someone saying when she stopped tryptophan abruptly she felt the same withdrawal effects as when she weaned off meds but based on my experience this is very rare.

After posting her question Amy made some adjustments – taking less of all of them. As I mentioned above I find it better to lower the amount of one amino acid at a time – kind of reverse of the trialing method you use when starting the amino acids. Also, since she mentioned she felt anxiety/panic creeping back up, I would have expected her to increase some of the calming amino acids.

Does the right dose ever change or need a tweak?

And to answer Amy’s other question: does the right dose ever change or need a tweak?

Yes, the “right dose” can change based on stressful life events especially if you have pyroluria – stressful life events can cause you to dump more zinc and vitamin B6 affecting serotonin and GABA production and increasing the social anxiety.

Amy does mention that she’s on the birth control pill and this depletes zinc and vitamin B6 and hence serotonin) and has an impact on the microbiome – so this may well be playing a role in the need to tweak doses.

There are many other factors that could lead to the need to adjust the amino acids (or other supplement protocols):

hormonal changes like PMS, perimenopause or menopause
something contributing to leaky gut like adding back gluten or accidental exposure to gluten
antibiotics (affecting the microbiome and serotonin/GABA levels)
artificial sweeteners (because of their effect on the microbiome and hormones)
starting on other medications (since many cause nutritional depletions)
adding in a new food like collagen/gelatin (for some people collagen and gelatin may lower serotonin levels)
running a marathon (it likely depletes zinc and may ramp up cortisol)
a formulation changing completely without you knowing (one example is Seriphos – used to lower high cortisol – where the core ingredient changed completely and the labeling stayed the same)
a product changing from using gelatin to cellulose capsules (this may be problematic if you have SIBO)
you move into a new home and get mold exposure
you get a new dog or cat and start using Frontline Plus for fleas (fipronil, the active ingredient, targets GABA receptors and recent research points to increased anxiety, aggressive behavior, memory problems)
you have started using a sauna (depletion of zinc and other minerals, as well as stirring up toxins)
your need for serotonin support increases as you head into winter-time (some low serotonin folks are more susceptible to the winter blues)
a recent course of fluoroquinolone antibiotics (impacts on magnesium and GABA levels and the mitochondria)
you may no longer need them

This is not a complete list of reasons that could impact you but this will give you an idea of what to start to think about.

Hopefully this shows how important it is to monitor how you’re doing and adjust as needed (either up or down) and think about what is changing in your life.

If you’d like to read about the amino acids products Amy uses – the same ones I recommend and use with clients – you can find them listed on my supplements blog.

We appreciate Amy for allowing me to share her results and posting these questions which are a great learning opportunity for you. She shared this with me:

I hope my “story” is helpful. Keep doing this important work! I work in the behavior health field. My colleagues think this is radical thinking and continue to only support the medical model. I’ve done a lot of my own research and trial and error. I wish there were more-open minded clinicians.

Hopefully with success stories like this, all the nutritional psychiatry research and behavioral health practitioners like Amy who have experienced it first hand and/or with clients/patients and family, we’ll change how mental health care is approached.

Do success stories like this lead you to be more open-minded about anxiety nutrition solutions? Have they worked for you?

And have you found the ideal dose of amino acids and then needed to adjust them up or down based on any of the above? How methodical were you in doing your adjustments?
