The correlation between terrible anxiety/panic attacks and collagen

July 25, 2025 By Trudy Scott 14 Comments

Bea shared her collagen experience and insights on one of the collagen blogs:

I discovered the correlation between terrible anxiety and collagen myself several years ago! Couldn’t find any data about it then so just assumed I was a weirdo. But then my 26 yr old daughter started having terrible panic attacks. And bam! She too had started a collagen supplement! So I realized at least 2 ladies have this trouble! Got me to think about how many women seek anti-aging help with collagen and then also end up on prescriptions to help calm terrible anxiety without seeing the connection. Practitioners don’t seem to know about this. But every vitamin shop I visit hears from me on the anxiety/collagen connection. Perhaps grassroots word of mouth will help others eventually.

And yesssss… for me, bone broth is equally horrible!! Even if it is simmered for only 30 mins.

Thank you for explaining, Trudy!! How fascinating to learn it’s the drop in serotonin! I’ve never tried Tryptophan… just a bit nervous. But I think it’s time. I sure need the bone broth for my waning gut health. And I’m weary of ruminating thoughts lately! Thank you immensely for shining a needed light on how these amino acids help! I only wish I could share lunch with you and pass along my grateful hug!

God bless you, Trudy!

I’m so glad Dea found this correlation for herself and her daughter! Collagen use is on the rise and there is little awareness about these effects on serotonin levels in susceptible individuals. Read on for many of the anti-aging benefits of collagen, more information about tryptophan depletion studies, another similar story, other possible causes, and other blog resources on this topic.

Collagen use as we age: for skin, joints and bone health

Her comment about an increase in collagen use for anti-aging is so true. This 2023 paper, Collagen supplementation in skin and orthopedic diseases: A review of the literature, discusses the many age-related benefits of collagen:

hydrolyzed collagen supplementation promotes skin changes, such as decreased wrinkle formation; increased skin elasticity; increased hydration; increased collagen content, density, and synthesis, which are factors closely associated with aging-related skin damage.

Regarding orthopedic changes, collagen supplementation increases bone strength, density, and mass; improves joint stiffness/mobility, and functionality; and reduces pain. These aspects are associated with bone loss due to aging and damage caused by strenuous physical activity.

This paper mentions these aspects about collagen, that it’s low in tryptophan and that it is not a complete protein i.e. it’s a low biological value protein:

Notably, collagen is a low-tryptophan protein, an essential amino acid for humans.
Collagen is a source of conditionally essential amino acids (glycine and proline), which are important in some physiological situations.
Collagen is a low biological value protein, since its amino acid composition is poor in essential amino acids. However, it has a positive intrinsic value because its amino acid composition is equivalent to that of human connective tissue.

This supports what we have learned from acute tryptophan depletion studies causing low serotonin.

Tryptophan-depletion studies to study the relationship between low serotonin and depression

Here is my first blog explaining acute tryptophan depletion studies (published in 2017) – Collagen and gelatin lower serotonin: does this increase your anxiety and depression?.

Tryptophan-depletion studies have been done for years, as a way to study the relationship between low serotonin and depression. Often a tryptophan-deficient amino acid mixture is used for this purpose. More recently, collagen and gelatin are being used.

Collagen and gelatin are an excellent source of these amino acids: proline, glycine, glutamine and arginine, but they do not contain the amino acid tryptophan.

This paper, Pharmacokinetics of acute tryptophan depletion using a gelatin-based protein in male and female Wistar rats summarizes what we find in a number of studies that use gelatin for the purpose of lowering serotonin levels, in order to study the relationship between serotonin and behavior:

The essential amino acid tryptophan is the precursor of the neurotransmitter serotonin. By depleting the body of tryptophan, brain tryptophan and serotonin levels are temporarily reduced. In this paper, several experiments are described in which dose and treatment effects of acute tryptophan depletion (ATD) using a gelatin-based protein-carbohydrate mixture were studied in male and female Wistar rats.

I encourage you to read the above blog to learn about who may be more susceptible to these effects.

I also share my personal experience with collagen consumption and can totally relate to Bea’s story and what clients and those in my community have shared.

Toni used collagen for 8 months – anxiety and panic attacks are off the charts

Toni experienced something similar:

I’ve been using Organic collagen for about 8 months now… love the hair and skin results. My tummy felt better at first but not currently. My anxiety and panic attacks are off the charts: panic attacks, heart racing, sweating, brain fog. I want to escape – like fight or flight. Definitely obsessing and fears. Memory difficulty. I have an upcoming GI appointment to check for Candida /SIBO… but I had no idea this could add to my anxiety. I’ll be looking forward to more information, Seriously.

And a few weeks after stopping the collagen she shared this:

I stopped using collagen. Since then, my anxiety and panic have decreased by less than half. Mild in comparison. I’m definitely taking a long break.

Instead of stopping collagen altogether, my advice is to figure out if low serotonin is the cause and address this with tryptophan or 5-HTP so collagen can be used for its many anti-aging and health benefits.

Is their anxiety due to reduced serotonin or histamine, glutamate or oxalate issues

Keep in mind tryptophan will help and allow collagen, gelatin and broth to be consumed without the increase in anxiety and panic attacks (and sleep issues) only if it is due to low serotonin.

Presumably both Dea and her daughter have other low serotonin symptoms – in addition to anxiety and panic attacks – such as sleep issues, worry, fears, afternoon/evening cravings etc (here is the list of symptoms). As you can see from Toni’s feedback (above), she does have many low serotonin symptoms.

A trial of tryptophan and symptom reduction (initially until the ideal dose is found) will confirm symptoms are related to low serotonin very quickly. This will also help Dea with her nervousness and ruminating thoughts, help her daughter ease the feelings of panic and help Toni too.

It’s also often helpful to also rule out histamine, glutamate and oxalate issues from collagen, gelatin and broth intake – as all of these factors can contribute to an increase in anxiousness too.

Additional blog posts on the topic of collagen

In case you are new to these potential issues, here are additional blog posts on the topic:

If you are new to this topic and are still skeptical about all this, do read the many comments and stories on these blogs. It’s a way more common issue than you’d think!

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

As always, I use the symptoms questionnaire to figure out if low serotonin 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. You can sign up to be notified when the next live launch is happening.

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.

Wrapping up and your feedback

I appreciate Dea for sharing her story on the blog and for sharing this information at vitamin stores – we do need more awareness, hence this new blog on the topic to further help create awareness.

It’s very likely that this is one big contributing factor to the rise in anxiety and sleep issues in perimenopause and menopause. And this is probably made worse because so many practitioners are still not aware.

I thanked her for her kind words, and said I’ll take a virtual lunch and a virtual hug from her.

Have you experienced any adverse effects from collagen, gelatin or bone broth?

Have you been able to continue using them by adding tryptophan?

And why do you use collagen/how is it helping?

If you’re a practitioner are you aware of this issue for certain susceptible individuals?

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

June 13, 2025 By Trudy Scott 10 Comments

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

I ran out of GABA and was so irritable and quick to rage (impacting my relationship with my son.) Back on it and feel so much calmer.

April 18, 2025 By Trudy Scott 5 Comments

Kaurie shared this feedback in the Facebook community:

I haven’t been taking my GABA for awhile (I ran out and forgot to order) and was soooo irritable and quick to rage. Back on it and feel sooo much calmer. Hopefully that’s the trick or I’m not sure what to do as it’s impacting my relationship with my son.

It’s not a good thing when it starts to impact your relationships. I was curious what this looked like for her and when I asked she shared this:

Any little thing will trigger me i.e. I couldn’t log onto my booktopia account- I ended up throwing my phone so hard it smashed (I had to buy a new phone which I couldn’t afford at the time). I get irritable at the tiniest things.

The good news is that a few days later she shared this: “GABA definitely seems to be helping!”

I’m thrilled for her and these great results, and appreciate her sharing and allowing me to share! I hope this continues to improve her relationship with her son and in other areas of her life too.

And in case you’re wondering, once you know your ideal dose of GABA it does work that quickly, provided it’s used sublingually, capsule opened, in powder or liposomal form or as a cream.

What we typically see with low GABA levels and some less-recognized signs

Low GABA is typically associated with feeling anxious with physical-tension and stiff-and-tense-muscles. The other common symptoms we see with low GABA are overwhelm, feelings of panic, and the need to self-medicate to calm down, often with alcohol but sometimes with carbs and sugary foods.

Sleep problems can also be caused by low GABA and you’ll experience physical tension with this (rather than the ruminating thoughts and worry which is the low serotonin type of insomnia). It’s not uncommon to experience both low GABA and low serotonin.

You can also experience anger, rage and agitation when GABA levels are low – this is not as recognized as the more common anxiety-related low GABA signs. You can read the entire list of low GABA signs and symptoms here.

This list includes other less-recognized signs of low GABA such as: inability to prioritize planned actions, poor focus/ADHD and spinning, intrusive thoughts/overactive brain, fear of heights, rectal spasms, visceral pain/belly pain with IBS, bladder pain/interstitial cystitis and urgency, Lyme-induced anxiety, globus pharyngeus (lump in the throat) and laryngospasms/“choking” episodes/swallowing problems, poor sensorimotor skills and sound and tactile hypersensitivity

Some possible GABA/glutamate mechanisms that may trigger rage and irritability

A letter, Tiagabine for Rage, Aggression, and Anxiety, published in the Journal of Neuropsychiatry and Clinical Neurosciences in 2015, offers some indirect support for this GABA rage observation. They are discussing patients with treatment-resistant rage and aggression and they propose that:

Gamma-aminobutyric acid (GABA), the primary inhibitory neurotransmitter, may be critical in the neurochemical control of aggressive behavior.

They share that the prescription medication called Tiagabine, a selective GABA reuptake inhibitor (SGRI), increases synaptic GABA availability. They report that 20 out of 36 patients aged 15-54 years (69%):

with symptoms of rage, aggression, or anxiety in association with one or more of the following disorders: bipolar, intermittent explosive, major depression, panic disorder, attention deficit hyperactivity disorder, or substance abuse …demonstrated a good or excellent response to tiagabine, with reduction or elimination of the symptoms of rage, aggression, or anxiety.

This paper, looks at females with bipolar disorder and ADHD and discusses the role of glutamate and GABA in impulsivity and aggression: “On a neurochemical level, glutamate and γ-aminobutyric acid (GABA) are considered important regulatory metabolites.”

GABA likely also helps quickly because of reduced anxiety, improved sleep, and being easily able to quit or eat less sugar, and quit alcohol too.

Based on some research I’ve found and my experience with GABA, I suspect GABA may also help in these ways over a longer period: countering a histamine reaction, reducing inflammation and impacting cytokines, improving progesterone levels, beneficial impacts on the microbiome, supporting the liver and toxin removal (such as fluorides), gut healing and reducing high blood pressure.

Low serotonin and low dopamine, as well as low GABA

Rage and anger has always been associated with low serotonin but we now know other neurotransmitters are involved too. The authors of Aggressive behavior and three neurotransmitters: dopamine, GABA, and serotonin–a review of the last 10 years state this:

The regulation of aggression by a wide spectrum of neurotransmitters is well known.

Serotonin has shown both inhibitory and stimulating effects on aggressive behavior, depending on the brain region measured and specific receptors where it acts.

Dopamine and the mesocorticolimbic system associated with reward seeking behavior are also associated with aggression. Dopamine can sometimes enhance aggression and sometimes reduce the impulsivity that might lead to abnormal aggression.

γ-Aminobutyric acid (GABA) is the main inhibitory neurotransmitter, and its relationship with aggressive behavior is extremely complex and highly associated with serotonin.

We use tryptophan and/or 5-HTP when there is rage, anger, irritability and other low serotonin symptoms of worry, fears, ruminations, obsessing, feelings of panic, perfectionism and lack of confidence. I have seen these amino acids change lives.

We use tyrosine for low dopamine symptoms of low mood, low motivation, poor focus and low energy. I have yet to see tyrosine help with anger, anger and irritability but it makes sense that it would reduce the impulsivity that may lead to an anger outburst or “abnormal aggression.” Interestingly I have seen tyrosine actually be calming for a few individuals. It’s highly unusual but it does happen from time to time, as this gentleman experienced.

GABA for rage, dark moods, OCD and histamine flares

Here are some additional blog posts on similar topics:

GABA helps ease symptoms of anger, rage, and dark moods (symptoms we typically associate with low serotonin)

My son who is 19 and on the autism spectrum was having issues with outbursts of anger and stuttering. These issues seemed to worsen during his senior year of high school. Since starting GABA and tailoring his dosage from Trudy’s instruction and feedback, we have seen a 90% reduction in stuttering and 80% reduction in anger and outbursts. We have done many supplemental protocols over the years and this is one of the few we have seen have an impact.

GABA worked amazingly for 18-year-old during a MCAS/histamine flare, helping with OCD, anxiety, rage and skin issues

GABA worked amazingly for us during a flare! Flares began with OCD [obsessive compulsive disorder]and anxiety increasing before our eyes and then the rage followed.

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

Have you found that GABA helps your rage and irritability issues? How do they show up for you and does this also impact your relationships?

Or do you find serotonin support with tryptophan or 5-HTP help more?

Or have you found tyrosine (to support low dopamine) works best for you?
Or is it a combination of the above?

Mouth-taping for improved sleep, the image of vertical taping that changed my mind and GABA and serotonin support if you still feel anxious

March 28, 2025 By Trudy Scott 19 Comments

mouth taping

I had been exploring mouth-breathing and using mouth-taping for my own personal use when I came across this paper, The Impact of Mouth-Taping in Mouth-Breathers with Mild Obstructive Sleep Apnea. I had tried mouth-taping a few times but it felt uncomfortable to completely seal my mouth with the large piece of tape I was seeing various health practitioners recommend. And to be honest, it also felt a little scary too, even though I already use tryptophan and GABA for sleep and anxiety.

As soon as I saw the image of the man with a narrow strip of mouth-tape it gave me confidence to start mouth-taping again and I haven’t looked back! I don’t have mild obstructive sleep apnea and don’t snore but I was aware I was starting to mouth-breathe and sleep with a slightly open mouth because of waking with an incredibly dry mouth.

I do not go a single night without it and love the benefits of improved sleep and more energy the next day, and no more dry mouth during the night. I know it’s reducing future tooth decay too.

I share more about the paper, where I first learned about mouth-taping (and an image of sealing the mouth completely) and how GABA and tryptophan may help alleviate any fear and anxiety you may still have about taping your mouth closed at night.

The image that changed my mind and excerpts from the mouth-taping paper

This is the image I’m referring to: the man on the top right with his mouth taped (as circled in yellow). You can see he has a narrow piece of tape, used vertically, instead of a wide piece of tape placed horizontally across his entire mouth/lips (I share an example of the latter below).

As you can see in the image above, there is a difference in “airflow during mouth-breathing vs. nasal-breathing” as indicated by the blue arrows.

Here is the study objective:

Many patients with obstructive sleep apnea (OSA) are mouth-breathers. Mouth-breathing not only narrows the upper airway, consequently worsening the severity of obstructive sleep apnea, but also it affects compliance with nasal continuous positive airway pressure (CPAP) treatment. This study aimed to investigate changes in obstructive sleep apnea by the use of mouth tape in mouth-breathers with mild obstructive sleep apnea.

And the conclusion:

Mouth-taping during sleep improved snoring and the severity of sleep apnea in mouth-breathers with mild obstructive sleep apnea, with AHI (apnea/hypopnea index) and SI (snoring index) being reduced by about half. The higher the level of baseline AHI and SI, the greater the improvement was shown after mouth-taping.

Mouth-taping could be an alternative treatment in patients with mild obstructive sleep apnea before turning to CPAP therapy or surgical intervention.

The snoring index is the number of snoring events per hour. And according to the Cleveland Clinic, the AHI /apnea/hypopnea index “identifies how many times your breathing slows or stops during an hour of sleep. You might see an AHI after a sleep study or on a CPAP machine.

The apnea-hypopnea index (AHI) is the average number of times you stop breathing (apneas) and have shallow breathing events (hypopneas) per hour of sleep.

The American Academy of Sleep Medicine uses a range to categorize the severity of apnea and hypopnea events in adults:

Mild: Five to fewer than 15 events per hour
Moderate: 15 to fewer than 30 events per hour
Severe: 30 or more events per hour”

In the above mouth-taping study, both the apnea-hypopnea index (AHI) and snoring index were reduced by about half, which I find impressive.

They used 3M tape that was “easy to adhere, easy to remove, and non-allergenic.”

My first introduction to mouth-taping and an example of taping your entire mouth with horizontal tape

This interview and taping demo with Mike Mutzel and Mark Burhenne was my first introduction to mouth-taping. It’s a fascinating interview and the benefits are numerous – do read the highlights and watch the interview.

As you can see, Dr. Mark Burhenne tapes his entire mouth with horizontal tape. This approach did not work for me and I gave up after a few tries.

mouth taping

If you have considered taping in the past and were put off or afraid because of this approach of taping the entire mouth, I’m hoping my insights below about taping vertically and the above study will get you trying it again.

How I tape my mouth and what I use

As mentioned above, I use a narrow strip of hypoallergenic paper tape that I simply tear off the roll each night. I sometimes use the same piece for a second night. I use lip ice/lip balm before taping as that prevents the tape from actually sticking to my lips. It feels more comfortable this way and still keeps my mouth closed. And it also allows me to cough and sneeze without feeling like I’ll lose skin on my lips. I can also sort of talk, although not very clearly, and it makes it easy to remove.

I do not go to bed without taping and it has added another element to improving my sleep. I do this together with the amino acids GABA, theanine and tryptophan, magnesium, Seriphos for high cortisol (when it’s high), eating low oxalates and calcium to counter the effects of oxalates, and avoiding EMFs).

If needed, I can slide a GABA Calm into my mouth without removing the tape. I will do this if I happen to need it due to waking in the middle of the night and not being able to get back to sleep.

If you are still fearful and anxious about trying this: serotonin and GABA support

If you are still fearful about taping your mouth closed at night, know you’re not alone! It felt a bit scary to me when I first started taping and I even yanked it off a few times during the night.

Trying it out in the daytime first definitely helps to get used to it. And it’s ok to test-drive taping for a few hours at night initially, and pulling it off later in the night.

Also, be sure to address low serotonin if you have low serotonin type of worry, ruminating, negative self-talk type of anxiety. With this type of anxiety, fears and phobias, and feelings of panic can be heightened. Personally, I use tryptophan and theanine for my low serotonin and also recommend this for clients and those in my group online programs. Keep in mind that some individuals do better with 5-HTP than tryptophan.

When you feel anxious, it’s common to have low GABA type of physical tension and anxiety. This may also make mouth-taping feel too overwhelming and give you feelings of panic. I’m a GABA girl myself and use GABA every night. I’m also getting some GABA support from the theanine I use. I know both are firm favorites with clients and group program members.

And, of course, an added bonus is that by addressing low serotonin and low GABA, we also address sleep issues which is a common sign of low levels of both these neurotransmitters.

Additional resources when you are new to using tryptophan, 5-HTP, GABA and other amino acids as supplements

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

If, 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, and is where this question was asked of me during one of the live Q&A calls.

Wrapping up and your feedback

Have you used vertical mouth-taping and if yes how has it helped you? Or are you fine with horizontal taping and covering your entire mouth? I’d love to hear how you tape, what tape you use and if you also use lip balm/lip ice before taping.

And if you have words of wisdom for newbies who may need some encouragement feel free to share this too!

I am curious if you have also used GABA, theanine, tryptophan or 5-HTP for overcoming the fear of mouth-taping and continue to use one or more of these amino acids for sleep support too?

The morning after a spine surgery, I had an anxiety attack and insisted on being allowed to take my GABA, which helped

February 28, 2025 By Trudy Scott 12 Comments

I’d been taking GABA before [my spine] surgery and really didn’t want to have to discontinue it. My surgeons have always insisted on me going off supplements in the week or more leading to surgery.

I’m sure they don’t want to have to be well versed on everything a person might be taking so they only allow prescription drugs.

The morning after the spine surgery, I had an anxiety attack and insisted on being allowed to take my GABA, which helped.

GABA helps tremendously in preventing me waking in the middle of the night or early morning in a panic. I take 500mg of NOW GABA sublingually before bed. I also take tryptophan and magnesium glycinate at bedtime and believe they help a bit, but GABA is the most effective.

It would be really helpful to be able to take needed supplements right up to surgery time.

LM posted this in response to my blog: GABA and theanine for sedation, anxiety, and cognition in preoperative surgical patients (a randomized controlled study) (more on this below).

She also said “This would be really nice” if doctors knew this! I’m with her – it would be really nice if doctors were aware of this research and allowed patients to use GABA and theanine right up to surgery and right afterwards too. This is especially relevant given the fact that GABA lowers blood pressure and high blood pressure is common after surgery (more on this below too).

Hopefully this GABA/theanine surgery research and the GABA/high blood pressure research will start to shift perspectives and guidelines, especially since increased anxiety also impacts the outcome of surgery. I share more on the research and my insights below.

The study: GABA and theanine are calming before a surgical procedure and don’t cause too much drowsiness

If you missed the blog post and study I shared above, here is the overview:

This novel study was planned to study and compare the effects of L-theanine and GABA on anxiety, sedation, and cognition in preoperative patients posted for major elective surgeries under general anesthesia.

The conclusion is that:

GABA and L-theanine result in effective preoperative anxiolysis with minimal sedation and improvement of cognitive skills.

In other words, both these amino acids are calming before a surgical procedure, don’t cause too much drowsiness and improve cognition.

Study participants used 500 mg GABA and 200 mg of theanine – but dosing is unique

The authors had the study participants use 500 mg GABA and 200 mg of theanine. Both were used as capsules and swallowed. If you’ve been following my work, you’re aware that I find sublingual (or powder or liposomal or topical) use of GABA to be more effective than swallowing a capsule. For this reason it’s possible that using a lower dose sublingually may be as effective or possibly even more effective.

As always, dosing of GABA (and other amino acids such as theanine) is individualized to the unique needs of the person. Ideally, the person has figured out their optimal dose for easing anxiety in their day to day life before going in for surgery. They may find that a higher dose is needed the weeks leading up to surgery and the day of surgery.

As LM shared, she uses “500mg of NOW GABA sublingually before bed”, and presumably started with a lower dose and worked up to 500mg i.e. the optimal dose for her unique needs. It’s very individualized with no-one-size fits all i.e. someone else may get similar benefits with 125mg.

Why you are told to stop all supplements prior to surgery

My understanding is that being told to stop all supplements prior to surgery is because of potential concerns about effects on bleeding, anesthesia and blood pressure. Unfortunately, the study didn’t address this possible issue. This article has some information on supplements (and some meds) to stop before surgery/anesthesia stating:

you may need to take a break from some supplements and medications that can interfere with anesthesia. Surgical complications could include heart or bleeding problems, prolonged anesthesia effects, or increased blood pressure.

GABA lowers blood pressure which may be helpful right after surgery

High blood pressure is common after surgery and can have far-reaching implications. According to this paper, “Postoperative hypertension often begins ~10–20 minutes after surgery and may last up to 4 hours. If left untreated, patients are at increased risk for bleeding, cerebrovascular events, and myocardial infarctions.”

This is another reason GABA may actually be helpful to use right up to surgery and right afterwards – it lowers blood pressure.

This paper, United States Pharmacopeia (USP) Safety Review of Gamma-Aminobutyric Acid (GABA), published in 2021, reports the results of a 4-week study that investigated the tolerability of GABA supplementation in mildly hypertensive but otherwise healthy adults:

The authors first established an optimum dose in mildly hypertensive subjects (SBP/systolic blood pressure between 130 and 180 mm Hg) who were randomized to receive oral doses of GABA at 0 (placebo), 20, 40, or 80 mg/day for 4 weeks.

An intake of 80 mg/day of GABA was associated with a significant reduction of the BP in adults with mild hypertension, and no adverse effects were reported.

A subsequent study evaluated long-term effects of GABA at 80 mg daily versus placebo in mildly hypertensive subjects for 8 weeks:

At the end of the 8-week study, SBP [systolic blood pressure i.e. the top number] and DBP [diastolic blood pressure i.e. the bottom number] were on average 5% lower in all the subjects who received 80 mg/day of GABA compared to participants in the placebo group whose blood pressure levels remained above normal.

This is a substantial reduction when 80 mg of GABA a day is considered a very low dose. I typically have my anxious clients start with 125mg GABA and increase from there. They may end up using 125 mg GABA 3 or 4 times a day and sometimes 250 mg a few times a day or 500 mg once a day like LM is doing.

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 may be an issue. The low GABA symptoms include: physical tension, overwhelm, fears, anxiousness, stiff and tense muscles, sleep issues, feelings of panic and stress-eating and drinking.

Wrapping up and your feedback

I appreciate LM for sharing how GABA helps her and her post surgery experience with anxiety and using GABA. It is wonderful that she was able to take her GABA supplement for the anxiety attack after her surgery. Let’s hope this research increases awareness amongst surgeons.

I’d love to hear from you – have you been told to stop all supplements before surgery, including GABA and other amino acids.

And do you feel increasingly anxious before surgery and other medical procedures and would GABA help i.e. is GABA and/or theanine part of your calming repertoire on a day-to-fay basis?

Have you ever discussed either of these two amino acids – GABA or theanine – with your surgeon or anesthetist prior to surgery and were they open to you using them before and right after surgery?

If you’re a practitioner do you recommend GABA and theanine to your anxious clients/patients and as a surgeon or anesthetist would you consider these amino acids in the future, based on this research?

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.

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.
