Exploring the Therapeutic Potential of Gamma-Aminobutyric Acid (GABA) in Stress and Depressive Disorders through the Gut–Brain Axis

January 31, 2025 By Trudy Scott 4 Comments

Research conducted on individuals with depression reveals that major depressive disorders (MDDs) coincide with diminished levels of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) in the brain, as well as modifications in the subunit composition of the primary receptors (GABA_A receptors) responsible for mediating GABAergic inhibition.

Furthermore, there is substantial evidence supporting the significant role of GABA in regulating stress within the brain, which is a pivotal vulnerability factor in mood disorders. GABA is readily available and approved as a food supplement in many countries.

Although there is substantial evidence indicating that orally ingested GABA may affect GABA receptors in peripheral tissues, there is comparatively less evidence supporting its direct action within the brain.

Emerging evidence highlights that oral GABA intake may exert beneficial effects on the brain and psyche through the gut–brain axis. While GABA enjoys wide consumer acceptance in Eastern Asian markets, with many consumers reporting favorable effects on stress regulation, mood, and sleep, rigorous independent research is still largely lacking.

Basic research, coupled with initial clinical findings, makes GABA an intriguing neuro-nutritional compound deserving of clinical studies in individuals with depression and other psychological problems.

This is the abstract from a recently published review paper: Exploring the Therapeutic Potential of Gamma-Aminobutyric Acid in Stress and Depressive Disorders through the Gut–Brain Axis

Does GABA exert calming and mood benefits via the gut-brain axis or is it really just a placebo effect? This paper discusses both possibilities. I’m excited by the former (and share more about this below) but I do not agree with the latter. Based on my clinical and personal experience, the calming effects of the amino acid GABA, used as a supplement (when you have low GABA symptoms/levels and used in a very specific way), is not a placebo effect. I also discuss this and share some cases that clearly confirm there is no placebo effect. Read on to be enlightened and encouraged about the power of GABA.

GABA and the microbiota-gut-brain axis

The authors describe the microbiome-gut-brain axis as “the bidirectional communication between the gastrointestinal tract, including its resident microbiota and the brain, linking emotional and cognitive centers of the brain with peripheral intestinal functions.”

They acknowledge that while we don’t quite understand the exact mechanisms of this bidirectional communication, “the vagus nerve, the endocrine and immune system, and the synthesis and metabolism of metabolites and neurotransmitters in the gut are critically involved.” This is exciting given what we know about the blood brain barrier.

If you are new to this concept of the gut-brain axis or want to read some of the latest updates, I encourage you to read the paper and learn about the benefits of probiotics (such as Lactobacillus and Bifidobacterium, and Lactococcus, Enterococcus, Streptococcus, and Leuconostoc) and prebiotics i.e. psychobiotics; and fermented foods – for mood improvement and stress reduction.

You’ll read this about GABA (both as a metabolite produced by the microbiome and as a supplement):

found in the enteric nervous system it contributes significantly to gut-brain axis functions and related disorders, including depression, anxiety, inflammatory, and cardiovascular disorders (they refer to GABA as a crucial ‘postbiotic’ i.e. a metabolite produced by the microbiome)
while GABA may not directly cross the blood-brain barrier in humans, an indirect influence through the enteric nervous system could potentially provide a viable pathway for the impact of GABA dietary supplements
although the connection between oral GABA administration i.e. GABA supplementation, the vagal nerve, and GABA levels in the brain has not been firmly established, considering the existing evidence, it represents a promising avenue for future research.

The last two bullets are worth emphasizing because one of the most common myths is that “GABA supplements don’t work because GABA is too big a molecule to get across the blood brain barrier.” It really doesn’t need to get through the blood brain barrier in order to be calming.

I share more about this in a blog I published in 2023 – you can read it here.

GABA is a lifesaver and helps with mycotoxin-induced anxiety

Joie has Sjogren’s, Hashimoto’s, fibromyalgia & collagenous colitis (all diagnosed after severe mold exposure) and shares how GABA

has been a life saver for me (for my anxiety), and I share this with all I know who experience anxiety. I also use L-theanine at night because of insomnia. The 5-HTP has helped somewhat for sleep. L-tryptophan didn’t seem to make a difference. However the 5-HTP has made a significant difference in lessening my daily pain levels, which I am most grateful for.

Micki Contini, MS CNC, a board-certified holistic health and nutrition consultant, is a friend and colleague whose life was hugely impacted by mold toxicity. She shares this about how GABA helped her:

As they started tearing my house apart for remediation, I started eating GABA Calm like candy. At the beginning I had to have a lot more than I do now. GABA Calm takes me down a notch and I feel my shoulder coming away from my ears and I get closer to relaxing.

Here are a few other blogs that illustrate just how calming GABA can be when used as a supplement:

If GABA works it’s a placebo effect?!

I find this statement in the conclusion of the review to be confusing given all that the authors share about the gut-brain axis, vagus nerve and bidirectional communication:

The dietary supplement form of GABA is readily accessible to consumers. While many individuals assert that they derive advantages from using these products, it remains uncertain whether these supplements provide benefits beyond what could be attributed to a placebo effect.

Their argument about conflict of interest and small sample sizes when it comes to studies doesn’t hold water with me.

As I mentioned above, based on my clinical experience, the calming effects of the amino acid GABA, used as a supplement when you have low GABA levels (and used in a very specific way), is not a placebo effect.

The following two cases clearly confirm there is no placebo effect (and these are just a few of many which I plan to share with the authors).

My 6 year old was having panic attacks getting out of the car for Kindergarten

My 6 year old son was having panic attacks getting out of the car going to Kindergarten and taking two GABA Calm has completely relieved him of his fears. He has been going for 3 straight weeks in a row.

I thought it may be low serotonin since this happened last winter as well but I gave him 5-HTP for a couple months and it didn’t seem to affect him and his anxiety. We had to have him repeat Kinder this year.

But wow, the GABA has been fabulous and Kindergarten is in full swing because of your help.

Lisa, a mom in the community, shared these wonderful results about her son. This is most definitely not a placebo effect.

You can read the entire story on the blog here. The school is actually in shock at how well carpooling is going for him.

GABA lessens anxiety, agitation and defiance in 98 year old mother who has been “sundowning” for a couple of years

My mother is 98 and has been “sundowning” for a couple of years. It starts around 3pm, sometimes earlier. Some days it’s no big deal. It is on those other days when she starts and then it goes to anxiety, agitation, then she can get sort of defiant which is so not her. She is a gentle soul, friendly, and kind so this is difficult on her as well as our family.

I just started to use my pestle and mortar to crush up a 125 mg GABA CALM supplement (Source Naturals) and I mix a little into her flavored yogurt when I start to see her having difficulty. I give it to her throughout the day. She only gets the 125 mg amount so I feel safe with that.

I believe that I do notice it lessens her anxiety. I pray that this will be helpful for her because that anxiety can be really draining for her. I have not noticed any adverse reactions.

This is another heartwarming success story shared by Marsha who used GABA Calm with her mother. It’s yet another one that is not a placebo effect either. You can read the entire blog post here.

My personal GABA results are also not a placebo effect

I can also share from first-hand experience that GABA was a life-saver for me in my late 30s when I had no idea what a panic attack was and knew very little about GABA other than the fact it calmed me down very quickly!

I still use GABA in various situations to this day: to help with back spasms after a fall, to help with rectal spasms, to help with throat spasms/pain caused by crying (after the loss of my darling mom), to help me sleep solidly and before doing an on-stage presentation, and much more.

GABA is effective and safe when used in a very specific way

Many people use GABA and report it didn’t work or that they had a strange or uncomfortable reaction to their GABA supplement (such as tingles or flush or feeling dizzy). I’m on a mission to educate folks how GABA is effective and safe when used in a very specific way:

Only if you have low GABA levels and symptoms of physical tension, overwhelm, fears, anxiousness, stiff and tense muscles, stress eating, drinking to calm down or fit in socially (you can see all the symptoms here)
Starting with a low dose of around 125mg (and less if you’re sensitive)
Only using it as a sublingual, powder or capsule opened on to the tongue, liposomal or GABA cream (to see results in 1-10 mins and to bypass the digestive system)
Titrating up (and sometimes back down) to find the ideal dose for your unique needs
Being open to trialing different products and forms and sometimes combining GABA with theanine
Understanding that there can be nuances to using GABA, making one change at a time and not giving up too soon
Tracking carefully and course-correcting as needed

I educate anxious individuals about all of the above and offer guidance and encouragement in the GABA Quickstart 2.0 online group 5 week program.

I hope this summary, the review paper and the cases leave you feeling enlightened and encouraged about the power of calming GABA.

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

As always, I use the symptoms questionnaire to figure out if low GABA or other neurotransmitter imbalances may be an issue.

If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control (this is covered in an entire chapter too), sugar cravings, anxiety and mood issues.

The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs.

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.

Wrapping up and your feedback

Have you experienced the benefits of GABA for stress and/or low mood? Do you believe it’s more than a placebo effect?

And are you excited to understand the possible mechanisms and read the research? Or do you just want to know how GABA could help you and how to use it?

Have you tried GABA without success or only had limited success? Feel free to share and I’ll provide my feedback.

Understanding the function of the GABAergic system and its potential role in rheumatoid arthritis (for pain, anxiety, sleep issues and more)

January 3, 2025 By Trudy Scott 2 Comments

This is a great question posed by a woman in my GABA/anxiety online group program:

Can GABA be good for rheumatoid arthritis, and in its early stages? If so, in what ways would someone see signs of improvement with GABA?

When I looked into some of the recent research on GABA and rheumatoid arthritis I was fascinated. A 2023 review paper, Understanding the function of the GABAergic system and its potential role in rheumatoid arthritis, discusses the relationship between rheumatoid arthritis (RA), an autoimmune condition, and GABA (gamma-amino butyric acid), a calming neurotransmitter.

The authors discuss “a new mechanism of action in RA” and the fact that “bidirectional communication occurs between the brain and immune system…and neuroinflammatory responses in the brain.”

The paper discusses GABA and neurosignalling, immunomodulatory effects and inflammation, stating that the:

GABAergic system may modulate the abnormal pain response in RA patients.

So to answer her question, if she has low GABA levels we would expect to see some reduction in her RA pain.

As always, we look for the signs and symptoms of low GABA regardless of the diagnosis or possible diagnosis. So if someone has low GABA symptoms of physical tension, overwhelm, fears, anxiousness, stiff and tense muscles, focus issues, pain, stress eating or drinking to calm down, and poor sleep, we consider a trial of the amino acid GABA, and could expect improvements in all or some of the above symptoms.

I would also recommend that she tracks markers of inflammation (like hs CRP, IL-6, IL-1β, and TNF-α) and RA markers to see if they shift in a positive direction with her use of GABA too.

I share more below about the incidence of anxiety and sleep issues in rheumatoid arthritis and some of the mechanisms covered in the review paper. Also, there are lab tests to track and there are other nutritional approaches for supporting an autoimmune condition such as RA.

Some of the mechanisms covered in the review paper

This image from the paper and the explanation provides some insights on the mechanisms at play.

Glutamate interacts with glutamate decarboxylase (GAD65 and GAD67) to produce gamma-aminobutyric acid (GABA).
Binding of GABA to GABA-A receptors inhibits macrophage activation and decreases the release of inflammatory factors such as IL-6, IL-1β, and TNF-α. Antigen presentation by antigen-presenting cells, however, is impaired, inhibiting CD4⁺ T cell proliferation and differentiation and reducing the expression of inflammatory factors such as IL-6, IL-1β, and TNF-α.
Pain signaling activates the P38/MAPK pathway, whereas GABA binding to GABA-A receptors inhibits P38/MAPK. The P38/MAPK signaling pathway contributes to inflammation and is involved in the activation of myocardin-related transcription factor A (MRTFA), myocardin-related transcription factor B (MRTFB), and serum response factor (SRF) that played key roles in fibroblast activation.

gaba and rheumatoid arthritis — Figure 1. Understanding the function of the GABAergic system and its potential role in rheumatoid arthritis

The authors don’t mention the use of the amino acid GABA as a supplement for RA but do list a number of clinical trials (mostly diabetes patients) where GABA has been used with success. It’s a start and I look forward to future research in this area.

Anxiety, depression, insomnia, cognitive issues and stress-eating in RA

This paper, Psychiatric aspects of rheumatoid arthritis: Review of literature, reports that

Among the major psychiatric disorders found in RA, the anxiety and depressive disorders are prevalent (13 to 48% of patients), as well as suicide, insomnia and tiredness. The impairment of quality of life is markedly after age 65.

This paper, A 30-Day Adjunct Wellness Intervention for the Management of Extra-Articular Symptoms of Rheumatoid Arthritis: A Formative Study, also mentions “cognitive and physical dysfunction” and “stress-related eating” in addition to anxiety, depression and insomnia in RA patients.

Doing a trial of GABA (and other amino acids such as tryptophan and d-phenylalanine/ DPA), will confirm which symptoms are related to which neurotransmitter deficiencies. It’s exciting to consider a very possible role of GABA and other amino acids given the fact that “individuals with rheumatoid arthritis (RA) continually fall short of treatment targets using standard drug therapies alone”

Looking further than GABA and other amino acids: a gluten-free diet and other root causes

With RA we obviously want to address more than just GABA (and other amino acids). Gluten removal is recommended but I do want to mention that the research is surprisingly mixed. This paper, Efficacy of gluten-free diet in patients with rheumatoid arthritis states that

Gluten seems to be a glycoprotein with a clinically relevant inflammatory effect. Several observational studies and anecdotal cases reported a correlation between gluten and various diseases, including autoimmune diseases, such as rheumatoid arthritis. This study aimed to evaluate whether gluten-free diet could be effective in controlling inflammation and ongoing rheumatoid arthritis symptoms.

We report 4 cases of patients with long-standing rheumatoid arthritis with no response to several conventional and biotechnological drugs, treated with a gluten-free diet concurrently with the drug therapy. Our patients presented different degrees of response to the diet, in terms of disease remission and improvement of symptoms. Our cases confirm that a gluten-free diet may improve symptoms of rheumatoid arthritis, even in patients resistant to conventional drug therapies.

Many other papers dismiss the role of gluten and inflammatory diets. This one is an example of a number of similar papers.

The benefits of addressing neurotransmitter imbalances with GABA and other amino acids means the addiction is stopped and quitting bread and cookies now no longer requires willpower,

Here are some autoimmune recipe resources:

In addition to dietary changes, a full functional medicine approach is warranted as there is much research supporting the benefits of the following for RA: omega-3 fatty acids, olive oil, low vitamin B6, addressing heavy metals such as mercury and much much more.

I cover 60+ root causes of anxiety here – I’d be carefully assessing each of these root causes for RA too.

Additional resources when you are new to using 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.

Wrapping up and your feedback

Do you have rheumatoid arthritis (RA) or another autoimmune condition and has GABA helped?

Were you aware of these possible connections?

What about dietary and nutritional approaches?

GABA works wonders for anal cramps (almost instantly) and relieves body aches in the hips and legs of a 75-year-old woman

May 17, 2024 By Trudy Scott 13 Comments

Dear Trudy, your recommendation of using GABA for anal cramps has changed my life. I don’t experience them often but when I do they are nasty. A crushed pill or open capsule on the tongue works wonders, almost instantly.

However, I want to add, after hearing your presentation on the Parkinson’s summit and your mention of relief from physical tension, that taking 500mg relieves body ache in hips and legs.

I’m 75, and have recently developed debilitating body aches. Taking one twice/day a.m. and p.m. has made a huge difference. Thank you for your brilliant blog.

Merril shared this wonderful feedback about how the amino acid GABA, used as a supplement helps her with anal cramps and also body aches. I never get tired of hearing feedback like this and as always, I like to share so I can educate further. This helps the person sharing the results and the community as a whole.

Today’s blog highlights more about the role GABA plays in muscle spasms and pain, and more about anal/rectal spasms in case this application is new to you. I also share other considerations when muscle spasms and/or pain are an issue: gluten, oxalates and low endorphins.

GABA works wonders (almost instantly) to eliminate anal cramps

I first blogged about GABA as a solution for agonizing rectal pain and spasms in 2017. I shared how I experienced the awful anal sphincter spasm and pain myself. The medical term is proctalgia fugax and is described as a condition that leads to rectal/anal spasms and sharp fleeting pain in the lower rectum or anus. In some people it can be more than fleeting and is often described as excruciating and agonizing.

The first time it happened to me I was terrified and beside myself not knowing what it was or what to do. I eventually figured out the solution because of what I knew about GABA helping to ease tense muscles and wanted to shine some light on this very painful condition.

As Merril says GABA “works wonders, almost instantly” to completely eliminate the pain. Take note that she says a “crushed pill or open capsule on the tongue.” GABA is most effective when used this way: sublingual GABA or GABA powder or liposomal GABA (and presumably GABA cream too).

GABA can also be used to prevent a full-on spasm if you catch it in advance i.e. when you first feel the twinges of a spasm coming on.

GABA relieves body aches/pain for her and in Parkinson’s patient

I love that GABA has the side benefits of also relieving her body aches in her hips and legs. It’s not unusual to use GABA or one of the other amino acids for a symptom and then discover it’s helping in another area.

And do appreciate that she picked up this tip when tuning into the Parkinson’s summit. I always share new information when I speak at summits and the amino acid and neurotransmitter information typically has varied applications.

During my summit interviews I had shared that working with a few people with Parkinson’s disease, GABA has been very helpful for the stiffness and pain, the physical anxiety, easing some of their tremors and helping with insomnia. I had one client whose husband had anxiety, insomnia, and leg pain and “thrashed around the bed at night.” GABA helped this man tremendously.

I shared this research: Molecular Imaging of the GABAergic System in Parkinson’s Disease and Atypical Parkinsonisms

A growing number of neuroimaging studies have focused on the association with different symptoms of Parkinson’s disease, thereby suggesting a GABAergic role in motor symptoms, gait disturbances, frontal cognition, somatic symptom disorder, and hallucinations.

Other ways GABA helps with pain and muscle stiffness

With regards to my comment above about GABA having many applications, when it comes to aches, pain and spasms, GABA helps with the abdominal pain of colitis, muscle stiffness and pain in those with multiple sclerosis and even bladder pain.

Gluten, sugar, gut health, and oxalates

She didn’t mention what her diet was like so just to be safe, I encouraged her to also check out my book “The Antianxiety Food Solution” to explore all the possible root causes that may be contributing to the anal spasms, pain and body aches – such as gluten (“tingling at 50%, numbness at 27%, pain at 20%, burning at 13% and “buzzing” feeling at 7%”) , gut health and SIBO (small intestinal bacterial overgrowth) and even sugar.

I mentioned that I don’t cover oxalates in my book but with body aches, spasms and pain I’d also explore this aspect. More on oxalates here and here.

Endorphin support with the amino acid DPA helps ease pain

When there is a neurotransmitter imbalance like low GABA levels it’s not uncommon to also have other neurotransmitter imbalances. With pain and aching I’d want to explore the possibility of low endorphins and do a trial with the amino acid DPA (d-phenylalanine) if low endorphin symptoms are present (you can find the symptoms questionnaire here).

DPA supports endorphin production (by inhibiting the breakdown of endorphins), reducing pain quickly, often in 2-10 minutes.

The use of DPA is not new information as you can read in this paper from 1982 – D-phenylalanine and other enkephalinase inhibitors as pharmacological agents: implications for some important therapeutic application

A number of compounds have been shown to inhibit the degradation of enkephalins. As expected, these compounds produce naloxone reversible analgesia [pain-relief] and potentiate the analgesia produced by enkephalins and by acupuncture.

One of these, D-phenylalanine, is also anti-inflammatory.

D-phenylalanine has proven to be beneficial in many human patients with chronic, intractable pain. It is proposed the enkephalinase inhibitors may be effective in a number of human “endorphin deficiency diseases” such as depression, schizophrenia, convulsive disorders and arthritis.

DPA also improves mood, especially when there is weepiness, and provides comfort when there is emotional eating. Here is one of many blogs that address DPAfor pain. Feel free to use the blog search feature to find others if you are new to this amino acid.

A few GABA product options – a sublingual, a powder and a cream

Some of the GABA products I recommend include Source Naturals GABA Calm lozenges and Now GABA Powder. You can purchase these from my online store (Fullscript – only available to US customers – use this link to set up an account).

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

As always, I use the symptoms questionnaire to figure out if low GABA or other neurotransmitter imbalances may be an issue.

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.

Wrapping up and your feedback

I do always appreciate feedback from the community and being able to share it on the blog. I’m thrilled Merril saw these benefits with GABA. She doesn’t mention if she has also seen benefits for sleep or feeling anxious or stress eating (all signs of low GABA too) – I’m curious to find out!

Now I’d love to hear from you – have you had success with GABA for anal/rectal spasms or other body aches, pains and muscle spasms? How much has helped and which product?

Have dietary changes or DPA also helped?

If you’re a practitioner have you seen GABA help in situations like this?

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

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

April 26, 2024 By Trudy Scott 18 Comments

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

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

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

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

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

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

Sugar alcohols in GABA Calm and other GABA chewable products

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

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

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

Using a mini measuring spoon set and GABA powder

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

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

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

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

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

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

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

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

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

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

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

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

Mixing and matching as an other option

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

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

Today I mentioned the Now GABA Powder and NFH GABA-T SAP. You can purchase these from my online store (Fullscript – only available to US customers – use this link to set up an account).

If you’re not in the US, the Now GABA Powder and Nutricology ZenMind (a GABA/theanine combination comparable to GABA-T SAP) is available via iherb (use this link to save 5%).

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

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

As a reminder, low GABA can cause physical tension, anxious feelings, feelings of panic and problems sleeping, as well as self–medicating with alcohol or carbs to relax or fit in. As always, I use the symptoms questionnaire to figure out if low GABA or other neurotransmitter imbalances may be an issue.

If, 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.

Wrapping up and your feedback

I do always appreciate questions like this so keep them coming so I can share and educate further.

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

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

Please share how GABA helps and how much helps you?

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

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

Phthalates (found in soft plastics and fragrances) are the new BPA and cause anxiety. Is this why the amino acid GABA is so often needed long-term?

June 10, 2022 By Trudy Scott 11 Comments

Using the amino acid GABA (as a supplement) for anxiety (the physical tension type of anxiety) should ideally be short-term to address your low levels of GABA (gamma-amino butyric acid). Why then do many folks only find relief when using GABA long-term? What is depleting their GABA levels on an ongoing basis? One reason is that anxiety is caused with ongoing exposure to phthalates (found in soft plastics and fragrances). Ongoing exposure can continue to deplete GABA levels so supplementation is needed long-term. This blog reviews sources of phthalates and the supporting (and growing) research. And also the fact that we’re being told that phthalates are safe.

The awareness and concern about BPA (bisphenol A), an industrial chemical found in hard plastics (and a contributing factor when it comes to anxiety), is being surpassed by an awareness and concern about phthalates (pronounced “thalates”).

I believe “Phthalates are the new BPA!” and “Fragrance is the new smoking!” and I suspect we’ll be seeing more and more research on the adverse health impacts (including anxiety and other conditions – more on that below) and hopefully more and more awareness too.

Here is a brief summary:

They act as binding agents and make plastics flexible….and are found in plastics in the kitchen, vinyl toys (it makes them soft), shower curtains, paint and nail polish.
They are also found in anything with a fragrance – like air-fresheners and most commercial house-cleaning products, and cosmetics such as shampoos, moisturizers, sun cream and of course perfumes, deodorants and after-shave products. I cringe every time I see the beautiful perfume ads on TV and when I walk past someone with loads of after-shave wafting behind them

My assumption is that you’ve heard of phthalates and know they are harmful. They are well-recognized as being an endocrine disruptor but less is known about the effects on GABA levels and increasing anxiety (more on that below).

If you are new to phthalates, the organization called Safer Chemicals Healthy Family, has an excellent overview. They share that

Food is the leading source of exposure. Phthalates have been found in dairy products, meats, fish, oils & fats, baked goods, infant formula, processed foods, and fast foods. Phthalates are not intentionally added ingredients but rather “indirect” food additives. They easily escape from food processing equipment, food packaging, and food preparation materials, and contaminate food at points all along the supply chain.

They list the many health impacts (with links to studies): Endocrine disruption (i.e. affecting your hormones); abnormalities in the male reproductive system; reduced testosterone levels and altered thyroid hormone production; neurodevelopmental effects in infants or children (ADHD-like behaviors, aggression, depression, a lower IQ, and autism); liver and kidney toxicity; cancer; and asthma.

This article also addresses the fact that we’re being told that phthalates are safe when they are not.

Phthalates are associated with emotional symptoms (depression, anxiety and stress) in male and female students

In addition to the above health impacts, phthalates play a role in causing anxiety too. This 2020 paper, Association of Urinary Phthalates Metabolites Concentration With Emotional Symptoms in Chinese University Students, reports the results of a school-based cross-sectional survey that was carried out among 990 university students aged 17-24 years:

the concentration of six phthalate metabolites in urine was measured (with a detection rate of 79.6% to 99.7%)
The positive rates of depressive symptoms, anxiety symptoms, and stress were 17.4%, 24.8%, and 9.5%, respectively
One type of phthalates affected the males more severely and another type affected the females more

The authors concluded that:

Our study demonstrates that Chinese university students are widely exposed to phthalates; and high- and low-molecular weight phthalates are associated with emotional symptoms in males and females, respectively.

It’s seldom one cause that is contributing to anxiety and emotional symptoms, as illustrated by this study: Association Between Screen Time, Fast Foods, Sugar-Sweetened Beverages and Depressive Symptoms in Chinese Adolescents. We need to address all factors. And here it’s a combination of screen time, as well as junk food and sugar, and the plastic containers and soda bottles that are a source of phthalates.

As you can see, fast foods are a huge source – Phthalate and novel plasticizer concentrations in food items from U.S. fast food chains: a preliminary analysis. This paper was published in May 2022 and already we’re seeing “certain ortho-phthalates (i.e., di-n-butyl phthalate (DnBP) and di(2-ethylhexyl) phthalate (DEHP)) have been phased out and replaced with other plasticizers (e.g., dioctyl terephthalate (DEHT))”. This mirrors what we saw with BPA being replaced with BPS and BPF, which are concerning.

The anxiety-inducing effects caused by phthalates could be alleviated by GABA

What is very encouraging is the fact that the amino acid GABA can alleviate the anxiety caused by phthalates. In this 2018 animal study, Intervention Effect of Gamma Aminobutyric Acid on Anxiety Behavior Induced by Phthalate (2-ethylhexyl Ester) in Rats. This is the conclusion:

DEHP [phthalate] exposure induced anxiety in rats, which may be achieved through elevating nitric oxide and nitric oxide synthase levels in the prefrontal cortex of rats.
The [anxiety-inducing] effects caused by DEHP could be alleviated by GABA.

This study was looking at Di(2-ethylhexyl) phthalate (DEHP), and the authors shared that “it is one of the most widely used phthalate esters.” As you can see from the 2022 paper I shared above, it’s now being replaced with other plasticizers.

This 2019 paper, Effect of di(2-ethylhexyl) phthalate on the neuroendocrine regulation of reproduction in adult male rats and its relationship to anxiogenic behavior: Participation of GABAergic system didn’t use the amino acid GABA but do report a “decrease in hypothalamic gamma-aminobutyric acid (GABA) concentration” and the authors “suggest that GABA could participate in the modulation of reproductive and behavioral DEHP effects.”

Long-term use of GABA because of phthalates: using GABA should ideally be short-term

We clearly need human studies to confirm all this but until then we can use what we know about GABA and supplement with the amino acid GABA (as a supplement) when there are low GABA symptoms of physical anxiety, tension, stiff and tense muscles, intrusive thoughts, insomnia, and self-medicating with alcohol or sugar.

As mentioned above, using GABA should ideally be short-term – 3 to 12 months – to address your low levels of GABA. I propose that many folks only find relief when using GABA long-term and it’s partly due to phthalates (and other chemicals) depleting their GABA levels on an ongoing basis.

I’m in favor of long-term use of GABA supplementation as long as GABA levels continue to be low and GABA supplementation offers relief.

But you also need to be addressing your exposure to these chemicals and doing ongoing detoxification. And also addressing diet, gut-health, infections, low zinc, low vitamin B6, low serotonin etc. (on an as-needed basis).

Addressing exposure and ongoing detoxification

As far as addressing our exposure to these chemicals, reduction and ideally avoidance is ideal. The Safer Chemicals Healthy Family overview includes plenty of practical steps.

As far as ongoing detoxification and nutritional support I encourage regular infrared sauna (my personal favorite is the portable Therasage sauna), rebounding, dry skin brushing, optimizing lymph drainage and exercise.

The research on NAC alone and a combination of zinc and NAC is encouraging even if it’s not specific to anxiety. Also, research shows that rosmarinic acid, a natural polyphenol “confers protection against DEHP-induced thyroid inflammation.”

You can read about other more general detox approaches on this pesticide spill blog: rooibos tea, castor oil packs, vitamin D (it’s often lower in those exposed to phthalates), epsom salts baths, apple cider vinegar and broccoli sprouts (as a source of sulforaphane).

Resources if you are new to using GABA as a supplement

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

If you suspect low levels of GABA 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.

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. This is a paid online/virtual group program where you get my guidance and community support. There are many moms in the program who are having much success with their kids.

Have you been using GABA for longer than 3-12 months? (please share how long and how it’s helping)

GABA mixed in water and swished in his mouth before a meal prevents esophageal spasms /choking/vomiting, and allows him to swallow

April 1, 2022 By Trudy Scott 24 Comments

GABA mixed in water and swished in the mouth of an adult male, before a meal, prevents his esophageal spasms, and stops his frequent choking and vomiting, and allows him to swallow his food. A colleague shared her husband’s swallowing issues after she read my blog post about using GABA powder inside the check for laryngospasms.

This is what she shared:

That [blog] made me think that [GABA] might be useful for my husband‘s esophageal spasms. He frequently can’t get food down during a meal because of them.

So he started mixing 500 mg GABA in a little water and swishing it around his mouth and then swallowing it at the beginning of each meal. Since he started doing that he has not had one spasm, or vomiting episode.

It’s wonderful to hear about her husband’s success with GABA and this unique application of swishing around GABA powder (mixed in water) in his mouth before a meal (I’ll share more on this aspect below).

I asked if they know what the causes of his esophageal spasms are but they don’t yet know:

We can’t figure it out. It appears to be all food. I would expect there to be a trigger-food, but we can’t find it.

The GABA has completely stopped it. Last night we went out to dinner and he forgot to bring GABA with him and immediately started choking. So he went to the nearest vitamin store, (of which there is only one)! Fortunately it was open. As soon as he got back to the restaurant and took his GABA, he was fine.

GABA does work so well for him and offers him some relief while they continue to search for other underlying root cause/s. Until these are found, GABA is supporting overall low GABA levels, associated with physical tension-type anxiety, intrusive thoughts, stiff and tense muscles in other areas of the body and also stress-eating and self-medicating with alcohol in order to relax. More on low GABA symptoms here.

My input on his dosing and swishing

Regarding the dosing and swishing method I have this input:

500 mg GABA is the ideal dose for his needs but this is considered a high dose to start. For low GABA tension-type anxiety, I have clients start with a trial of 125 mg GABA and go up from there. I’d recommend the same approach for someone with issues like this gentleman experiences.
GABA is most effective when used sublingually or by opening a capsule on to the tongue or by using GABA powder on the inside of a cheek, rather than swallowing a GABA capsule. For this reason, his method of swishing GABA mixed in water is excellent for achieving the spasm-reducing and relaxing benefits quickly. For some folks doing this 30 minutes before a meal may be more effective than doing it right before eating.

The diagnosis can vary from person to person

The diagnosis can vary from person to person. But as long as there are spasms that are affecting swallowing, doing a trial of GABA is worthwhile in order to determine if it will help.

One example is eosinophilic esophagitis where

Clinical manifestations in infants and toddlers generally include vomiting, food refusal, choking with meals and, less commonly, failure to thrive. Predominant symptoms in school-aged children and adolescents include dysphagia (difficulty swallowing), food impactions, and choking/gagging with meals, particularly when comprised of foods with coarse textures. Other symptoms in this patient population include abdominal/chest pain, vomiting, and regurgitation.

The predominant symptom in adults is dysphagia [difficulty swallowing]; however, intractable heartburn and food avoidance may also be present.

One paper, Esophageal microbiome in active eosinophilic esophagitis and changes induced by different therapies discusses the role of the microbiome and how “an increase in levels of gamma-aminobutyric acid (GABA) …is known to exert a role in esophageal motor function.”

Finding the other root causes (other than low GABA)

Regarding finding the root causes, other than low GABA, this is an important aspect that does need to be pursued. Here are some of the many factors worth considering:

Finding food triggers. This can be challenging but an obvious one is gluten which can play a role in eosinophilic esophagitis. Dairy and environmental irritants can be issues too.
GERD/reflux needs to be ruled out or addressed. Food sensitivities are often a factor here too.
Vagus nerve issues can play a role in digestive issues like this. GABA and vagus nerve exercises helped my cough and voice issues. I recorded all my exercises on video and you can find these here. Fortunately I didn’t have any swallowing or choking episodes at that time but have had a choking episode more recently (GABA did help) so I know how scary this can be.
Pyroluria, a social anxiety condition needs to be ruled out or addressed too. This is because nausea, gagging and choking are common symptoms for some individuals.
I’d also consider a tongue tie. I just finished reading Tongue Tied: How a Tiny String Under the Tongue Impacts Nursing, Speech, Feeding, and More (my Amazon link) by Richard Baxter, DMD, MS. The focus on babies and children but adults can also benefit from addressing tongue tie issues later in life.
Addressing gut health and the microbiome may be one of the keys, as outlined in the paper above.

This is not a comprehensive list and a full functional workup will help to identify all possible root causes.

Resources if you are new to using GABA as a supplement

If you are new to using the the amino acid GABA as a supplement, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see the low GABA and other low neurotransmitter symptoms).

If you suspect low levels of GABA or low serotonin 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.

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 GABA products that I use with my individual clients and those in my group programs.

If you don’t feel comfortable reading my book, doing the low GABA symptoms questionnaire and doing trials of GABA on your own, 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 experienced throat or esophageal spasms and difficulty swallowing with choking and/or vomiting.

And do you have the low GABA physical-tension-type-anxiety symptoms? What else is a trigger for you and do you have a diagnosis?

If you’ve already been using GABA with success for easing your anxiety, have you noticed a reduction in your swallowing issues?

Have you ever used GABA in this way to help your swallowing issues?

If you’re a practitioner please share what you have seen?
