My kids and I used GABA to get through Hurricane Helene – I recommend it for everyone’s 72-hr kit now

July 15, 2025 By Trudy Scott 2 Comments

My kids and I used GABA to get through Hurricane Helene. Freeways broken in 3 directions, no comms, no gas, no power, etc. GABA noticeably kept us calmer even as the days went by. It helped us stay calm enough to think about our escape plan and jump on opportunities to find gas and water.

So grateful we learned about it [from you years ago] and had it on hand… I recommend it for everyone’s 72-hr [emergency preparedness] kit now.

Alecia shared her wonderful results with GABA on a Facebook post. I’m sorry they went through this but I am so happy GABA helped. I also wish everyone had GABA on hand for situations like this.

She now also uses a manual device for vagus nerve stimulation (VNS) and feels a combination of “GABA and VNS would have been incredible.” I’m a big fan of a B complex too and zinc and extra B6 if you have pyroluria because the added stress depletes these nutrients and makes things worse. And serotonin and endorphin support can often be helpful too. More on all this below and details about the GABA product she used and what dose helped her.

Which GABA product helped her and her family and how much did she use?

I asked Alecia to share how much GABA helped during and after the hurricane and which product worked for her? And if she had been using it before for day-to-day low GABA symptoms of feeling anxious, stressed, overwhelmed with physical tension and sleep issues.

We use the pharmaGABA by Natural Factors. I usually only need 100 – 200 mg in my regular life. During the hurricane I needed 300 mg pharmaGABA a couple of times a day. And more when waiting in a gas line. Such intense stress. GABA really took the edge off.

It’s always helpful to know your baseline dose i.e. what you use on a day-to-day basis. And to expect that dose to increase in times of the added stress in the midst of the hurricane and the immediate aftermath – as it did for Alecia. She needed a higher dose and used it more frequently.

You may often find you need to continue with the higher dose for a few weeks to months after the disaster, especially during the clean-up and rebuilding period.

One other factor to consider is the form of GABA. She used pharmaGABA with much success and many do very well on this form but I find more folks do better with GABA. GABA works best when used sublingually, capsule-opened, powder (all held on the tongue 1-2 mins) or cream, and a low starting dose is used, and increased to find the optimal dose.

Vagus nerve stimulation (VNS) as an added benefit

Alecia now also uses a manual device for vagus nerve stimulation (VNS). She had it during Hurricane Helene but had not yet used it:

A combo of GABA and VNS would have been incredible. I found out my mom was diagnosed with stage 4 cancer the next week and finally started using both GABA and VNS. Game changer combo.

She has the Hoolest veRelief Prime device and says this:

I love the Hoolest VNS. It helps with anxiety, sleep, digestion, and higher performance. I like level 4 but my kids prefer level 1.

I used it daily for about 4-6 months and then I started to heal deeply. Now I only need it once every week or two.

(I did hear that her mom’s treatments are working)

Vagus nerve stimulation, anxiety, GABA and the potential with VNS devices

This paper, Vagus nerve stimulation: a physical therapy with promising potential for central nervous system disorders, discusses how “vagus nerve stimulation influences the central nervous system through the GABA system” and the fact that “VNS has been shown to alleviate anxiety symptoms”, depression, obsessive-compulsive disorder (OCD), panic disorder, and post-traumatic stress disorder (PTSD). Much of the research has been done with implantable vagus nerve stimulation (iVNS) but the potential with non-invasive vagus nerve stimulation devices is really exciting.

What is so interesting is that “Vagus nerve stimulation influences the central nervous system through the GABA system” and it’s “speculated that part of VNS’s therapeutic effects …might involve the GABA system.”

VNS benefits are also seen via impacts on serotonin and dopamine, BDNF (brain-derived neurotrophic factor), by reducing inflammation and the secretion of inflammatory cytokines and promoting neuroprotection.

You can read more about vagus nerve support on this blog: Vagus nerve rehab with GABA, breathing, humming, gargling and key nutrients. I share my vagus nerve/throat issue and how manual vagus nerve support exercises and GABA helped me.

Using a good B complex and the pyroluria protocol too

I told Alecia that I’m a big fan of a good B complex and the pyroluria protocol too. I share more in this blog – Nutrition solutions for psychological stress after a natural disaster.

If this is all that can be managed it would be my first choice for everyone. In fact, if you live in an area prone to hurricanes, floods, fires etc. I’d recommend being on a B complex all the time.

My colleagues Bonnie Kaplin and Julia Rucklidge published this paper in 2015: A randomised trial of nutrient supplements to minimise psychological stress after a natural disaster. Those consuming a B-Complex and a broad-spectrum mineral/vitamin formula showed significantly greater improvement in stress and anxiety than study participants consuming a vitamin D supplement.

It is well known that pyroluria symptoms are made worse in times of heightened stress. If you are on protocol for pyroluria, additional zinc and vitamin B6/P5P is likely going to be needed short-term too.

In addition to GABA I also mention serotonin and endorphin support:

Serotonin support with tryptophan or 5-HTP, especially if you’re feeling sad, worried, imagining the worst, feeling fearful and having problems sleeping. More on tryptophan products.
Endorphin support with Lidtke DPA if you’re feeling especially emotional and weepy and grieving the loss of your home and community. More on endorphins here.

And I also include some resources for disaster preparedness and things to consider after the fangers have passed (like mold toxicity).

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 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 Alecia for sharing her story and giving me permission to share on the blog.

Do you have GABA on hand all the time and include them in your 72-hr emergency preparedness kit?

Have you found vagus nerve stimulation (VNS) to be helpful – either manual exercises (which ones help you) or using a device (which one helps you)?

What about B vitamins and the pyroluria protocol – do they help too?

If you’re a practitioner do you recommend GABA, VNS, B vitamins and the pyroluria protocol?

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.

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?

I had chemotherapy and have not been able to get off sugar since. How long will it take 5-HTP or tryptophan to stop the cravings?

July 26, 2024 By Trudy Scott 4 Comments

Lauren shared her struggle with sugar cravings that started after chemotherapy, asking her question on a recent tryptophan/DPA cravings blog post:

If I try the tryptophan or the 5-HTP and one or the other works, how long will I need to take them for the sugar cravings to stop?

Back in 2021 I had been off sugar for 2 years and it was easy to get off by slowing eliminating sugar. The last elimination was from my coffee and then it was easy to stay away from sugar.

I had chemotherapy for 6 months in 2022. I have not been able to get off sugar since then. After chemo ended, I had the cravings and don’t know how to end the cravings.

Any advice from you would be appreciated.

The good news is that if you have cravings that are caused by low serotonin and you find your ideal dose of tryptophan or 5-HTP, you will notice reduced sugar cravings immediately and they will be further reduced with consistent use, typically a few times a day.

The key is to figure out if your cravings are caused by low serotonin and then it’s a matter of doing a trial of either tryptophan or 5-HTP (if you get results and other low serotonin symptoms improve it’s a clue you’re on track). And then you need to figure out the ideal dose for your unique needs. I share more about all this below and additional information about other types of cravings caused by neurotransmitter imbalances (and the respective amino acids that help).

Since her cravings struggles started after chemotherapy I also discuss possible impacts on neurotransmitters and also candida (sugar cravings are very common with the candida). Read on for my response to the above question from Lauren.

Sugar cravings caused by low serotonin: tryptophan or 5-HTP may offer immediate results

As I mentioned above you will notice reduced sugar cravings immediately with either tryptophan or 5-HTP if your cravings are caused by low serotonin. A big clue with low serotonin-type sugar or carb cravings is that they are more intense in the late afternoon and evening.

A good place to start (as always) is with the symptoms questionnaire. If there are other low serotonin symptoms such as feeling more anxious, worried, fearful with a low mood and irritability etc, that further confirms it’s worth doing a trial.

Some folks do better with one than the other but I have clients start with tryptophan and then switch to 5-HTP if their results are not as expected. In both instances we open the capsule or use powders or a chewable to get instant feedback on the benefits. So in that first session Lauren should be able to say “wow my cravings have reduced from 10/10 to 5/10” within 5-10 minutes. She may also report she feels more optimistic and less worried.

It is possible that her cravings are not caused by low serotonin or that they are a combination of a number of factors.

Sugar cravings caused by other neurotransmitter imbalances, and other amino acids to the rescue

We also look at sugar cravings caused by low GABA (stress eating because of physical tension), low endorphins (comfort eating or emotional eating), low dopamine (eating for an energy boost or improved focus) and low blood sugar (eating due to crankiness and irritability).

Lauren would know if any of the above may be factors based on her scores on the symptoms questionnaire i.e. scores for cravings and other symptoms. This offers further clarification:

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

As you can see there is an amino acid for each of these imbalances and it’s a matter of doing a similar trial for each one. With the correct dose, Lauren can expect quick results too, provided she finds the ideal dose for her needs.

This is the blog post Lauren posted her question on: Tryptophan and DPA (d-phenylalanine) for cravings and sleep issues (and a concern about 5-HTP and nightmares).

It’s one of many posts on the site about amino acids and sugar cravings so I encourage you to use the search feature of the blog.

Chemotherapy: impacts on serotonin and dopamine

Because chemotherapy has an impact on serotonin and dopamine, this may be where Lauren needs to start when considering which amino acids to trial. Here is some additional information on “chemobrain” or chemotherapy-induced cognitive impairment:

… a medical complication of cancer treatment that is characterized by a general decline in cognition affecting visual and verbal memory, attention, complex problem solving skills, and motor function. It is estimated that one-third of patients who undergo chemotherapy treatment will experience cognitive impairment.

Alterations in the release and uptake of dopamine and serotonin, central nervous system neurotransmitters that play important roles in cognition, could potentially contribute to impaired intellectual performance in those impacted by chemobrain.

And this may offer an explanation as to why she hasn’t been able to quit sugar since chemotherapy.

Chemotherapy, candida albicans and sugar cravings

If none of the above approaches reduce her cravings or if they do help to some extent but are not quite enough, we have to keep looking for root causes.

A big clue is that Lauren had been able to quit sugar using willpower in the past but has struggled since chemotherapy. It’s important to consider the role this may be playing. In cancer patients who have gone through chemotherapy there is increased susceptibility to Candida albicans, “a fungal commensal and a major colonizer of the human skin, as well as of the gastrointestinal and genitourinary tracts.” This is reported to be caused primarily by “chemotherapy-induced depression of innate immune cells and weakened epithelial barriers, which are the body’s first-line defenses against fungal infections.”

Sugar cravings are very common with candida and in some cases can be so severe that no amino acids will work until the candida is addressed. Interestingly, in one candida study, short exposure to serotonin resulted in antifungal activity so it’s possible that tryptophan or 5-HTP helps.

I don’t have my candida symptoms questionnaire on the blog but you can find a mini version on page 93 of my book, The Antianxiety Food Solution and additional information and my dietary/nutrient protocol in chapter 5 of my book.

The full candida questionnaire can be found in William G. Crook’s excellent book, The Yeast Connection and Women’s Health (my Amazon link).

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

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

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

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms too). This is a paid online/virtual group program where you get my guidance and community support.

Wrapping up and your feedback

I appreciate Lauren for posting her question on the blog so I can share and we all can learn.

Now I’d love to hear from you – does any of this resonate with you? If yes, what approach helped reduce your sugar cravings after chemotherapy?

If you’re a practitioner have you seen these approaches work well with your clients/patients?

GABA Calm and 5-HTP twice a day, after struggling with ADD-like symptoms, have made our day-to-day life so much better!

June 14, 2024 By Trudy Scott 14 Comments

Kimberly is a mom in the community and shared this wonderful feedback about her 8-year old son who is using just two amino acids:

I started my son on Gaba Calm and Serotrex (5-htp) twice a day after struggling with ADD-like symptoms for about 9 months. I’m not sure if he really has ADD or if his gut problems are to blame, but the amino acids have made our day-to-day life so much better!

I think we may need to do some work with his nervous system and on helping him learn to regulate his emotions, but he’s much less mouthy and argumentative than he was before. We still have hard days, but the supplements have helped pull me out of being exhausted and discouraged all the time from fighting with him constantly over everything.

I never get tired of hearing feedback like this and it’s not uncommon for young children (and adults) to see benefits like this very quickly.

She doesn’t know if he has ADD (attention deficit disorder) but she used the amino acids based on his symptoms (low GABA and low serotonin). We know it was the right choice because of his results. Could his symptoms improve even further? Absolutely! We typically increase one amino acid at a time watching for further improvement and stop when we reach the ideal dose.

Because she says “we still have hard days” I’d want to see her increase the GABA and 5-HTP (as mentioned above) and also consider a trial of DPA/d-phenylalanine (for low endorphin emotional symptoms) and possibly tyrosine (for low dopamine focus and attention issues). Low blood sugar can also cause an emotional rollercoaster and eating for blood sugar stability and glutamine helps so much.

When I hear “mouthy” and “argumentative” I immediately consider low serotonin but low blood sugar comes to mind too.

These additional amino acid trials would also be done one at a time with careful tracking of symptoms and adjustments up and down as needed.

If you’re not familiar with the symptoms of low serotonin, low GABA, low endorphins, low dopamine and low blood sugar you can see them all here.

Kimberly acknowledges that they may need to do work in other areas too – like learning to regulate his emotions and addressing gut issues. This is good as it’s seldom just one approach that is going to shift things.

Kimberly has also seen benefits with 5-HTP

I also love this feedback from Kimberly because she is less exhausted and no longer discouraged because her son is doing so much better.

By the way, this mom also experiences benefits from amino acids. 5-HTP helps her with sugar cravings. I shared her feedback in a blog post last year: Would using 5-HTP or tryptophan help when you crave sugar (as a sort of antidepressant) late afternoon/evening?

I was taking a break from tryptophan/5-HTP and realized after reading this post that that might be a mistake! So I added 5-HTP back in mid-afternoon and my sugar cravings are almost completely gone.

And 5-HTP also helped her late afternoon sadness and despair:

I took a 50 mg 5-HTP along with my mid-afternoon Endorphigen capsule, and within just a few minutes I felt the sadness and despair that I often feel in the late afternoon, start to lift. I was astonished at how quickly it worked!

I just love it when the amino acids work for mom and then mom helps her child.

It goes without saying that dietary changes are foundational in situations like this – often for the entire family. This means eating real whole foods, quality animal protein (especially at breakfast to help with blood sugar stability), organic veggies and fruit, fermented foods, healthy fats and no sugar/gluten/caffeine (all covered in detail in my book).

Assessing for and addressing nutritional deficiencies (like low zinc, low vitamin B6, low omega-3s, low iron etc.), removing toxins, addressing the gut (more on this below) and addressing infections are all important too. It’s always a comprehensive approach. But the good news is that you start to get results right away with amino acid supplementation, while you are figuring out everything else.

Gut issues and 5-HTP/serotonin and GABA

As mentioned above Kimberly also suspects possible gut problems with her son. These could include dysbiosis (microbiome imbalance), food sensitivities, leaky gut, parasites, candida and or digestive enzyme issues etc. These always need to be investigated and addressed – because they can all contribute to low GABA and low serotonin – but until the issues are resolved, you can start to see some symptom resolution with the amino acids.

The amino acids he is taking offer an added gut benefit too. In an animal study, Effects of Serotonin and Slow-Release 5-Hydroxytryptophan on Gastrointestinal Motility in a Mouse Model of Depression, 5-HTP was shown to normalize gut motility and growth of the enteric epithelium. The paper concludes that slow release 5-HTP “might be used to treat patients with intestinal dysfunction associated with low levels of serotonin.”

Interestingly, an in-vitro (test-tube) study found that: “Serotonin showed antifungal activity towards all isolates of candida.” This was for certain strains, such as albicans, glabrata, tropicalis, and a few others).

This review article published earlier this year, Gamma-aminobutyric acid as a potential postbiotic mediator in the gut-brain axis discusses the role GABA plays in “psychological disorders, including anxiety, depression, and stress” and also attention deficit hyperactivity disorder. The authors also share that GABA has an impact on “gut microbiota composition” and confirms what has been reported in other research and what we see clinically: the “possibility that GABA may be a potent mediator of the gut-brain axis.”

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 low serotonin or other neurotransmitter imbalances may be an issue.

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

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms too). This is a paid online/virtual group program where you get my guidance and community support.

Wrapping up and your feedback

I’m thrilled Kimberly saw these benefits with 5-HTP and then helped her son with 5-HTP and GABA. I asked if I could share here to inspire other moms and give them hope and she said yes. I do always appreciate feedback from the community and being able to share it on the blog.

Now I’d love to hear from you – Does any of this resonate with you? If yes, which amino acid has helped you and your child and how has it helped?

If you’re a practitioner have you seen GABA and 5-HTP help in situations like this?

DLPA vs DPA for pain, food cravings, depression, grief, lack of joy; and impacts of DLPA on sleep, and feeling more stressed/anxious

April 5, 2024 By Trudy Scott Leave a Comment

A very common question I get is from folks asking about the difference between the amino acids DPA (d-phenylalanine) and DLPA (dl-phenylalanine) for endorphin support and endorphin/dopamine support. I dedicate an entire blog to this question explaining the differences and which one I use for weepiness, heart-ache, pain and energy. I also discuss where tyrosine (for dopamine support) fits in. If you missed that or need a recap you can read about this on the blog.

The blog post generated some great questions that I’m sharing today, with my feedback, in case you have similar questions. I discuss a question about DLPA vs DPA for pain and impacts on sleep; a question about DLPA (used by mistake) raising already high dopamine levels and why DPA isn’t working any more for food cravings; a question about using DPA with GABA; and a question about DPA for depression and lack of joy caused by grief.

Here is the question from Gloria who shared this feedback about her use of DLPA (as part of a pain relief product) but says she can’t use it past noon. She also wants to know more about DPA for pain relief:

My experience with DLPA is as part of a supplement called Curamin for pain relief from arthritis that also has curcumin and boswellia. It works quite well in the AM but I can’t tolerate it past noon or it negatively affects my sleep.

Interesting to learn it is similar to tyrosine which I have had sleep problems with in the past.

Does DPA work as well for pain? Is it best to take amino acids on an empty stomach for best absorption? Does that mean an hour before a meal or two hours after? Thank you for your blogs and book!

It’s great that this combination product offers pain relief and it’s good that she has made the connection to poor sleep when it’s used after noon. This is a popular product that I would like to see include the possible impacts on sleep and the other precautions for DLPA . It is a proprietary formulation so you don’t actually know how much DLPA you’re getting. I really don’t like not knowing.

One other concern is that curcumin is high-oxalate and for some this can make pain worse. Otherwise, curcumin and boswellia are excellent for pain relief and reducing inflammation.

DPA is more effective for pain than DLPA because it offers a bigger endorphin boost. If oxalates are not an issue, one option could be to continue with the Curamin before noon and if needed, add standalone DPA in the afternoon and evening, for added pain relief.

Amino acids are more effective on an empty stomach and even more effective when opened on to the tongue. I share more about opening DPA onto the tongue in this blog.

DLPA (used by mistake) raised already high dopamine levels and why isn’t DPA working any more for food cravings?

Rhonda shared how she found out the difference between DPA and DLPA the hard way and wants to go back to DPA:

I certainly found out the difference the hard way. I had used Lidtke Endorphigen for a few years and I think it helped a bit with food cravings. As I am in Australia, I depend on my sister’s visits from US for my supply. When I ran out last year, I bought DLPA by mistake.

After 1 week I was unable to cope with life, totally stressed out about everything, wanting to cry or scream or run away. Zero tolerance towards anyone. After 10 days I realized my mistake and I went back to normal in 24 hrs.

I believe DLPA resulted in very high dopamine as I already have a very slow COMT gene activity for breaking down dopamine.

I now take Endorphigen again but not seeing much effect on sugar cravings this time.

That is quite the reaction she experienced but I’m glad she figured it out so quickly. It’s not uncommon for some folks to react to DLPA like this, feeling more stressed and even anxious. High dopamine, and norepinephrine and epinephrine (so a huge adrenalin rush), related to slow COMT activity could well be the cause.

When Endorphigen (or any of the amino acids) work well initially we continue with trials of higher doses to find the ideal dose. It may also be that a reset is needed after the shift in dopamine.

Rhonda did say she thinks Endorphigen “helped a bit with food cravings.” When it only helps a bit it may be that the dose isn’t high enough or we may need to consider other neurotransmitter imbalances. They can all cause cravings for slightly different reasons: GABA/stress, serotonin/worry or low mood, glutamine/low blood sugar. More on that and the respective amino acids here.

Can GABA be used with DPA?

Ray asks: “Can I use GABA 25mg and also take DPA? Would either/or offset the other?”

My feedback: If someone has low GABA symptoms and GABA helps and they also have low endorphin symptoms and DPA helps then they are absolutely fine to use together and even at the same time. However, I have my clients trial one at a time in order to find the ideal dose and so you know how each one is working

What can I use for my depression and lack of joy, caused by grief?

Vee says she needs something “to get through my grief depression”:

Completely flat, no joy. I always had a calm flat disposition, but now it’s a complete zero. I need my brain to produce some oxytocin so I can like myself, my family and remember all I should be grateful for. I sleep good. I don’t take any meds, and I don’t abuse alcohol. Does tyrosine affect the brain in the way of producing oxytocin?

My feedback: I use DPA/Lidtke Endorphigen for this very purpose. It’s wonderful for grief, depression, lack of joy and the weepiness we see with low endorphins. It also helps with emotional eating that can show up as we try to self-medicate with treats in order to try and feel better.

When the depression also includes being flat, blah and curl-up in bed we use DLPA instead of DPA, or a combination of DPLA/DPA or tyrosine/DPA. Trials of each, one by one, helps you figure out what works best for your unique needs.

And for some folks GABA is helpful as shared by this woman who found GABA allowed her to sit with a feeling of peace and calm most of the time after her mum passed away.

Research does shows a link between dopamine and oxytocin, with oxytocin “emerging as one particular neural substrate that may be influenced by the altered dopamine levels.” Also, for oxytocin support I’d focus on hugs, massage, touch, laughter, making love, yoga, and petting a dog or cat.

DPA and DLPA product options

Products I recommend include Lidtke EndorphiGen (which is DPA) and Pure Encapsulations DL-Phenylalanine (DLPA). 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, these products are available via iherb: Doctor’s Best D-Phenylalanine (or DPA) and Life Extension D, L-Phenylalanine (or DLPA) (use this link to save 5%).

Additional resources when you are new to using DPA and DLPA, and other amino acids as supplements

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

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 (over and above the few I mentioned above).

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 and feedback like this so keep your questions coming. I do hope my sharing these ones have been helpful to you.

How has DPA or DLPA helped your pain, depression, lack of joy, weepiness, and grief? And has DLPA affected your sleep or made you feel more anxious or stressed?

If yes, which products have helped and do you find swallowed or capsule opened is more effective?

If you’re a practitioner do you use DPA and/or DLPA with clients/patients?

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

Using tryptophan and GABA amino acid supplements together for anxiety, sleep, ruminations and TMJ: questions and answers

February 23, 2024 By Trudy Scott 18 Comments

I am taking 250 mg tryptophan, 100-200 mg GABA. Tryptophan is helping with rumination. GABA is helping with feeling less tension in the body. I am also taking 500mg DPA. DLPA used to help me but I thought it was too stimulating so I’m trying DPA now. I couldn’t feel much when taking it on its own.

But the combination of tryptophan, DPA & GABA is generally helping me to feel less wound up. I still struggle with rumination and I have a really difficult time making decisions. I get really overwhelmed when I have a lot of decisions to make – it sends me in a tailspin and leads to more rumination. I’m not sure which amino acid would be good for that?

I generally have trouble relaxing and feeling calm and I feel the tension in my body. I am not sure if I should try increasing the dosage of one of the above?

I am wondering, is it important to take l-tyrosine to balance the tryptophan since tryptophan can lower dopamine over time? Or is the DPA enough since it’s a precursor to tyrosine?

I get many questions like this about using both tryptophan and GABA amino acid supplements together for easing anxiety and today I’m sharing some of these questions and my answers. This will also give you the opportunity to ask questions you may have related to using both these amino acids together. You’ll also read many success stories like the above and how to tweak the amino acids for optimal results.

Read on for my response to the above question from TT and other questions about using GABA and tryptophan together – how to measure GABA and serotonin levels for using with teens, adding tryptophan for sleep separately from GABA, how to test both for jaw clenching, and the precaution about serotonin syndrome.

My response and feedback for TT – adjustments for even better results

My response and feedback for TT … It’s wonderful that this combination is helping so much. It’s a great start but there are adjustments I’d consider to get even better results. The tryptophan dose is low, with a typical starting dose of 500mg so I’d consider increasing this a few times over a few weeks to see if the ruminations decrease even further. This may also help with the overwhelm and decision making.

Increasing the GABA over a few weeks (after the trial of increased tryptophan) may well improve her ongoing tension and inability to relax. I’d want to make sure she is using GABA sublingually for the best effects.

She asks about the need to take tyrosine to balance the tryptophan but I don’t have clients do this as a rule of thumb and only have clients take tyrosine if they have symptoms of low dopamine. In this instance since TT mentions difficulties with decision-making, a trial of tyrosine may be worth considering, after she has increased tryptophan and increased GABA. More about tyrosine benefits here.

I do want to mention that DPA is not a precursor to dopamine but DLPA does offer some dopamine support. I share more about the differences between DPA and DLPA here.

I want to give my teens GABA and tryptophan – how do I measure GABA and serotonin levels?

I have two teenagers ages 14 and 16 who suffer from anxiety and depression. My daughter has more difficulty with depression and my son with ruminating thoughts . My father had similar issues. We have tried supplements, and medications that help a little.

I want to try giving them GABA and tryptophan, but to make sure that they in fact meet the criteria you describe. Is there a lab test that measures GABA and serotonin levels? Also, how can I figure out the dose and times to give them?

Here is my feedback for Maria …. The best way to determine if someone may have low GABA/serotonin is to look at the low GABA/serotonin symptoms questionnaire (here is that link), rate 1 or 2 symptoms on a scale of 1-10 with 10 being worst, do an initial one-off trial of the respective amino acid and rate the symptoms again right afterwards (in the next 2 to 30 minutes). Based on this we decide if we’ll continue with the amino acid and how much to use.

Dosing is unique to each person’s needs and timing differs for each amino acid – tryptophan is best mid-afternoon and evening and GABA throughout the day and evening if needed too.

I don’t use the urinary neurotransmitter test as it’s not considered an accurate assessment. I blogged about this here.

It’s a comprehensive approach – amino acids AND diet. This mom mentions supplements and medications but nothing about what their diets are like right now – gluten-free, sugar-free, caffeine-free, eating protein at breakfast for blood sugar control, real whole foods, grass-fed red meat, wild fish, fermented foods etc?

I also suggest my book “The Antianxiety Food Solution” as a great place to start when you are new to the amino acids and other anxiety nutrition solutions like gluten/sugar/caffeine removal, blood sugar control, gut health, pyroluria etc.

And this blog is a wonderful example and gives hope to moms – Tryptophan for my teenager: she laughs and smiles, her OCD and anxiety has lessened, and she is more goal oriented and focused on school. It’s one of many similar blogs so be sure to use the search feature to find others.

GABA and theanine help my anxiety, if I add tryptophan for sleep should I take it separately?

I have taken Gaba and L-theanine for anxiety for the last few years on and off as recommended by a doctor, it really does help although I still have sleeping problems. I also have a lot of symptoms on your low serotonin list so if I add tryptophan to see if it helps with sleep should I take it with the Gaba or separately?

Here is my response and feedback for Diane … I was glad to hear GABA and theanine are helping with the anxiety. I have many clients with low serotonin and low GABA symptoms take GABA, theanine and tryptophan at bedtime at the same time for improving sleep that is caused by low serotonin.

Diane has already identified that she has a lot of low serotonin symptoms from the questionnaire, so like I shared for Maria above, a trial is worth considering.

We always want to capitalize on what is already working so when GABA/theanine is helping with anxiety and offers some help with sleep we will often increase that before considering a trial of tryptophan.

I’m assuming she is addressing dietary factors too and other root causes that may also affect her sleep – like low blood sugar and high cortisol.

Would GABA or tryptophan help with jaw clenching and how do I test to see if they would help?

Would Gaba or tryptophan help with jaw clenching, not grinding, which I assume is an anxiety thing even when I’m unaware of any anxiety? Since I already use Gaba on and off for anxiety or if I can’t sleep (only taking 200 mg) how would I go about testing tryptophan to see if it would help for clenching?

Here is my feedback for Diane … Jaw clenching/TMJ (temporomandibular joint) issues can be related to both low GABA because of the muscle tension and also when serotonin is low.

In the same way we do a trial with the amino acids for anxiety or low self-esteem (or another symptom like cravings) we would do a trial for the jaw clenching i.e. rate the severity on a scale of 1-10 with 10 being worst, do a trial of tryptophan and then GABA (separately) and rate the symptoms again right afterwards (in the next 2 to 30 minutes). And go from there, increasing each as needed (one at a time) and tracking symptom improvement.

Here is a case as an example: Tryptophan ends TMJ pain, headaches and worry, and improves mood and sleep.

Precaution about serotonin syndrome with tryptophan/5-HTP

There are precautions when using certain amino acids and I always review them with all my clients. If they have been prescribed an SSRI, I have them discuss the use of tryptophan/5-HTP with their prescribing doctor so they can be monitored for serotonin syndrome. With careful monitoring and doctor approval I feel comfortable having my clients use tryptophan/5-HTP 6 hours away from their one and only SSRI.

If they are using more than one SSRI and/or a combination of psychiatric medications, the use of tryptophan/5-HTP is not advised.

None of the above applied in these situations but it’s important to be aware of.

Tryptophan and GABA product options

Products I recommend include Lidtke 500 mg Tryptophan, 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).

If you’re not in the US, Doctor’s Best L-Tryptophan 500mg and Source Naturals GABA Calm lozenges and Now GABA Powder are products I recommend on iherb (use this link to save 5%).

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

We use the symptoms questionnaire to figure out if low serotonin or low GABA or other neurotransmitter imbalances may be an issue for you.

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), if you need serotonin support, the Serotonin QuickStart Program is a good place to start. This is 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. We take a deep dive into product options including Lidtke products and others if you’re not able to access Lidtke.

Low GABA can also affect sleep and cause stress eating. If you also have low GABA symptoms, the next step to get help is the GABA QuickStart Program. This is also a paid online/virtual group program where you get my guidance and community support. Another option is the budget-friendly GABA QuickStart Homestudy Program.

This blog is a follow-on from the previous blog on this topic so be sure to read that blog too. It also features many valuable questions in the comments and my responses, hence this new post. I hope this has been helpful for you.
