Rebound insomnia after tapering a benzodiazepine: will taking GABA or any other natural supplement interfere with healing?

By Trudy Scott 16 Comments

rebound insomnia after tapering

This question was posted on one of the GABA blog posts by Fran, asking about about using GABA for insomnia shortly after having tapered a benzodiazepine she had used for 15 years:

I am a senior who took benzodiazepines (clonazepam) on advice of my doctor for sleep because of chronic fatigue for 15 years. Last year I weaned myself off the medication and it has been just over 10 months. No one tells you that when you stop taking them you go into a rebound insomnia phase and it can last a long time. The doctor still won’t admit that!

I joined benzo buddies, a group I found out about on your site and found much encouragement from the posts of many brave and determined people. One post mentioned that the drug actually overrides your GABA receptors so when you stop taking it they have to heal to become active again. My question is: Will taking GABA or any other natural supplement interfere with that healing. The writer of the post feels taking nothing is best for the brain to return to normal and that only time will do that.

I said I was sorry to hear about her struggles with her benzodiazepine prescription. Sadly it’s all too common and it’s seldom that folks are cautioned about the rebound insomnia and other issues seen with benzodiazepines.

I love benzo buddies and other benzo support groups and often recommend that clients join one of these groups for the community support aspect. I am really happy that Fran found encouragement.

However, I  respectfully disagree with their message that GABA supplements or other supplements should not be used and that you should just wait for time to heal. We want to use everything at our disposal in order to heal as quickly as possible. And quality sleep is imperative for healing.

Also many of the most severely affected folks are part of these support groups, so it may well be all that they know, hence the advice they dispense.

Many do get relief with GABA during and post benzo taper and it won’t affect long-term healing (with a very low dose)

It is true that GABA receptors can be affected by benzodiazepines but despite this, many of my clients and others in my community do get relief from GABA during this period. Since we are all unique, some folks may have an issue, so we always do a trial with GABA if someone has rebound insomnia (and other low GABA symptoms of physical tension/anxiety, stiff and tense muscles, stress eating etc).

When someone can’t tolerate GABA they will know very quickly – typically in 1-2 days. If you can’t tolerate GABA it may feel the same as someone who takes GABA and doesn’t need it (i.e. GABA isn’t low) or when someone takes too much. This could make you feel light-headed, dizzy, feel a flush and/or feel too tired. You may even feel more anxious. Vitamin C is a wonderful antidote to all this and these short-term adverse reactions won’t interfere with long-term healing.

We also start with a very small dose – I typically have someone start with 25mg GABA and go up from there – and only use sublingual GABA. For some very sensitive folks we will start even lower as in this example where Syd gets sleep and body anxiety benefits with just 1.5 mg to 3 mg GABA.

Other nutrients that may also help with insomnia

We may also use other nutrients to help with sleep support and rebound anxiety (which is also common) and other symptoms, all based on each person’s unique needs. These may include tryptophan or 5-HTP if serotonin is also low (this can affect sleep and cause worry/ruminating type anxiety), melatonin if that is low (either sublingual or timed-release) and Seriphos if cortisol is high too. We may also combine GABA with theanine (research shows the combination may help some folks).

A full functional medicine and nutritional workup is recommended in order to be as nutritionally stable as possible. Ideally this happens before tapering starts but even if it’s done after the fact it can help with healing and symptom relief. Addressing histamine imbalances is one factor to consider as this can impact sleep (more on that below).

This is an important question that many folks ask so I appreciate her asking so I could share it as a blog post for others in a similar situation.

I am waiting to hear back about what happened when she did use GABA and how much she used. She mentioned that she did take GABA for a time at first but it only worked for a while. I find that during the taper and post taper, GABA needs can fluctuate as healing starts to take place. I have clients adjust up and down as needed.

More on benzodiazepine withdrawal and histamine issues

These medications have the most debilitating withdrawal reactions in all of medicine and Valium blocks DAO/impacts histamine levels:

Benzodiazepines (Xanax, Klonopin, Ativan, Valium, Librium, and others) as well as Z-drugs (Ambien, Lunesta and others), which are similar, have the most debilitating withdrawal reactions in all of medicine.

This happens in regular, everyday people who are taking the medications exactly as their doctor prescribed. It also happens to people on what they think are “low doses” and is not just a “high dose” problem.

Many people doing a benzodiazepine taper are often switched to Valium which is a DAO [diamine oxidase blocker (or histamine liberator)] and this further prevents histamine from being removed from the body [and can lead to increased anxiety].

Dyes are also triggers…the pink Xanax can be problematic.

GABA is as effective as benzodiazepines (which should only be prescribed for short-term use)

Many folks who have used benzos in the past, find GABA to be as effective. Another woman in my community, Dee, shared that she had taken Xanax in the past for panic attacks and her functional medicine doctor suggested GABA Calm as she wanted a natural product. This is her encouraging feedback: “I was amazed how it works just like the Xanax did – instant calm feeling within 10 mins of taking 2 capsules. I use them as needed when I am having heightened stress and anxiety.”

Ideally we want to use GABA instead of one of the benzodiazepines – which are all too commonly prescribed for anxiety, insomnia and pain – in order to avoid tolerance issues, dependence and withdrawal/tapering issues. The fact that they are used long term – like 15 years for Fran – further compounds the issues. Even a few months can be problematic for some folks. It’s important to be aware that this class of medication is intended for short-term use  i.e. 2-4 weeks only.

Resources if you are new to using the GABA and other amino acids as supplements

If you are new to using GABA and any of other the amino acids as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the symptoms of neurotransmitter imbalances, including low GABA).

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

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control, sugar cravings, self-medicating with alcohol and more.

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. You can find them all in my online store.

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

If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. This is also a paid online/virtual program with an opportunity to interact with me and other practitioners who are also using the amino acids.

Have you used GABA with success while tapering a benzodiazepine or shortly after tapering is complete?

Have you used other nutrients to help while tapering or post taper? If yes, which ones?

Did you find that GABA was not helpful? (which product and how much did you use?)

SSRI/antidepressant impact on the microbiome, discontinuation syndrome and safe tapering

By Trudy Scott 2 Comments

 

Antidepressants can have an antibiotic effect, causing dysbiosis and impacting serotonin, GABA and dopamine production. This can cause psychiatric symptoms and even suicidal thoughts or behaviors. Various SSRI (selective serotonin reuptake inhibitors) and SNRI (serotonin norepinephrine reuptake inhibitors) have more of an effect than others. And the top known side effects for SSRIs are gut symptoms: nausea, diarrhea and vomiting.

These medications are seldom prescribed with informed consent and can cause severe psychological, cognitive, physical and neurological withdrawal side effects (also known as discontinuation syndrome). A functional medicine and nutritional approach using 5-HTP, GABA, theanine and glycine can often be used to smooth the taper process.

Dr. Achina Stein addresses all this in her interview, SSRI Impact on the Microbiome and Safe SSRI Tapering, on The Anxiety Summit 5: Gut-Brain Axis.

achina stein and trudy scott

We cover the following:

  • Antibiotic effect of antidepressants: dysbiosis and impacts on serotonin/GABA/dopamine
  • Withdrawal/discontinuation syndrome symptoms of SSRIs and benzodiazepines
  • 5-HTP, GABA, theanine and glycine to smooth the taper process

Here are a few snippets from our interview.

We start with a discussion on the antibiotic effect of antidepressants and a review of this paper – Serotonin Reuptake Inhibitors and the Gut Microbiome: Significance of the Gut Microbiome in Relation to Mechanism of Action, Treatment Response, Side Effects, and Tachyphylaxis.

Dr. Stein comments on this study sharing how SSRIs affect the gut and microbiome in many different ways:

  • “This paper is important. It’s one of several papers that talk about how the SSRIs or serotonin reuptake inhibitors affect the gastrointestinal tract. And as you know, the gastrointestinal tract is really full of serotonin.
  • SSRIs, as well as other psychotropic medications, actually exert an antibiotic effect, which can have a direct consequence in disrupting the integrity and stability of the gut microbiome.
  • And the ones that are most likely to do that are Sertraline, fluoxetine, and paroxetine in that order. And it’s followed by fluvoxamine, escitalopram, and citalopram, having the least impact.
  • What they’re noticing is that this antibiotic effect actually results in dysbiosis.
  • The top known side effects for SSRIs are gut symptoms: nausea, diarrhea, vomiting.
  • We know that the gut microbiome has a significant effect on emotions, behaviors, and metabolic changes.
  • And it’s involved in the metabolism of drugs, and this combination is what really causes psychiatric symptoms and even suicidal thoughts or behaviors.”

She also talks about the bidirectional gut-brain connection/communication, the microbiome and short-chain fatty acids (which are a common theme you’ll hear throughout the summit):

  • “There is this huge connection between the gut microbiome and the brain.
  • And there’s also other indirect communication pathways because we’ve always wondered, well, how does this happen that the gut is connected to the brain?
  • So the other pathways which are more indirect are the hypothalamic-pituitary-adrenal axis.
  • And there’s also an immune-mediated connection where there’s a communication between short-chain fatty acids and microglia in the brain.
  • So short-chain fatty acids are the main metabolites produced by the microbiota in the large intestine through bacterial fermentation of indigestible polysaccharides, which are dietary fiber and resistant starch. And they possess neuroactive properties. So they influence the communication between these short-chain fatty acids between the gut and the microglia of the brain.
  • And it’s a bidirectional communication too.”

And we talk about tachyphylaxis or the poop-out effect of antidepressants.

The discussion on the SSRI (selective serotonin reuptake inhibitors) and SNRI (serotonin norepinephrine reuptake inhibitors) discontinuation syndrome (or withdrawal symptoms) is eye-opening and sobering, Here are just a few of the many psychological symptoms that she says patients may experience when tapering:

I’m just going to read them off because I think it’s important for people to know: mood swings, unstable moods, hypomania, hyperarousal, anxiety, medication-induced agitation – which is described as being caffeinated – impulsive behavior, aggression, irritability, crying spells, lowered mood or depression.

Dr. Stein also shares the many cognitive, physical and neurological side effects, and how she works with her patients with a functional medicine and nutritional approach to try and mitigate the side effects. She likes to use 5-HTP, GABA, theanine and glycine to smooth the taper process.

We also have a lengthy discussion about informed consent and the fact that it’s not happening and should be.

We do a deep dive into all this and much more.

The interviews that dove-tail well with this topic are as follows:

  • My interviews, GABA & Tryptophan: Gut-Anxiety Connections and Glutamine, DPA and Tyrosine for Anxiety and Sugar Cravings. The amino acids help during the  tapering process and help you make the dietary changes.
  • Thiamine Deficiency in Anxiety and Gut Health (Part 1 and 2) with Chandler Marrs. She talks about how medications can deplete thiamine. Could this contribute to some of the severe discontinuation syndrome symptoms we see?
  • Anxiety, Gut-Brain Communication and Diet with David Perlmutter, MD, FACN, ABIHM. This one gives you an excellent overview of the gut-brain communication and fermented foods, short-chain fatty acids and histone deacetylases (HDACs).
  • Gut-Brain Axis and Mental Health with Peter Bongiorno, ND, LAc. This is also a great overview on the mental health impacts of the microbiome. He goes deep into serotonin and GABA production mechanisms.

I encourage you to tune in if you have:

  • Anxiety & feel overwhelmed & stressed by little things
  • Panic attacks &/or obsessive thoughts or behaviors
  • Social anxiety/pyroluria
  • Phobias or fears (flying, spiders or even driving on a highway)

And also if you suffer from…

  • Food sensitivities, IBS/SIBO, parasites or gallbladder issues
  • Constipation, diarrhea, bloating, gas, pain & other digestive issues
  • Leaky gut, a leaky blood-brain barrier or vagus nerve issues

Join us if you are also an emotional eater with intense sugar cravings (and know you suffer from low blood sugar), experience insomnia, low mood, PMS, poor focus and/or low motivation.

This is THE online event to learn about the powerful individual amino acids – GABA, theanine, tryptophan, 5-HTP, glutamine, DPA and tyrosine – to quickly ease anxiety and help with gut symptoms while you are dealing with other root causes which take longer to address. (They also help with cravings as with this example, and sleep and immunity).

With research-based anxiety nutritional solutions and practical steps, you can determine your root causes, ease your anxiety and prevent it from coming back so you can feel on top of the world again!

If you are a practitioner, please join us too and find advanced solutions for your clients or patients too!

Dr. Datis Kharrazian’s GABA Challenge for a leaky blood brain barrier is a theory and we still have much to learn

By Trudy Scott 16 Comments

gaba challenge theory

I highly respect Dr. Datis Kharrazian and his work and had the pleasure of interviewing him last November on the Anxiety Summit 5: Gut-Brain Axis. During our preparations I asked if we could talk about his GABA challenge for a leaky blood brain barrier and he graciously agreed.

I wanted to address this topic in our interview because two of the most common questions I get asked are these:

  • “How can GABA work if it can’t cross the blood brain barrier?” and
  • “If GABA works does this mean I have a leaky blood brain barrier?”

We had such a great conversation on the topic I’ve decided to pull this part of the transcript into a blog so I can share it here with you and use the blog link to share it more widely as I’m asked these questions on social media and elsewhere.

You will learn how Dr. Kharrazian came up with the GABA Challenge, what his thoughts are today, his reservations with GABA and my excellent results with low doses of sublingual GABA. I also share some links to success stories, some of the research and how to figure out if GABA is for you.

Here it is, word for word.

Trudy: So while we’re talking about the leaky blood brain barrier, I want to just talk briefly about GABA and the GABA challenge that you have proposed as a tool for testing for a leaky blood brain barrier. And as you know, I use GABA extensively with clients with the low GABA physical type of anxiety.

I’ve always been a huge fan of you and your work but we do have a professional difference of opinion in this area. And I’ve never actually been a proponent of using the GABA challenge, and I’ve been pretty vocal about it. So I’m really glad that we had a discussion about this in the Facebook group of your neuroinflammation training, and you shared some insights because I was asking some questions about this.

I’d love you to just share some of what we talked about in that discussion. Because if we don’t talk about it, my community is going to say, “Hey, why didn’t you talk to Dr. Kharrazian about this?”

Dr. Kharrazian: Sure, no problem. I don’t think we have this big a disagreement. I think we just have different ways of looking at what’s out there and what we are observing as people working with people, patients who have anxiety.

So ultimately, we have a bunch of theory right now and a bunch of potential models, but we don’t have any clear studies to show what’s really happening. So, one of the things that I proposed in my book before… you understand, I was working with brain patients for over 20 years now….before we had S100 B readily available for many years, it was only in research; you couldn’t get it from conventional labs, even though research was showing it. And the blood brain permeability test was not available either. These have really become more available the past five years and prior to that, we didn’t really have a great test to evaluate if the blood brain barrier was breached.

In an effort to work with what’s out there, what we could do, one of the things that I was doing was doing a test that we called the GABA challenge test. It was really based on the lactulose mannitol test. So the lactulose mannitol test is a well-established test in gastroenterology where they measure leaky gut. So, in that test what the person does is they consume a monosaccharide and a disaccharide, lactulose and mannitol. Lactulose is a disaccharide, it’s very large, and mannitol is very small. And if mannitol doesn’t get absorbed, then there’s a malabsorption issue. And if lactose, which is very large; that should not get through the tight junctions of the gut, gets absorbed in a post urine test, after they drink it, then it shows they have leaky gut. So the whole premise of when you find particle sizes too large to cross, can be a clue to an indication of permeability.

So the GABA challenge that I write about in my book, Why Isn’t My Brain Working? (my Amazon link) was really a way for us to have patients consume GABA. If you look at the molecular weight of GABA, the Dalton size, it’s several hundred Daltons. Several hundred Daltons cannot cross the blood brain barrier. So the concept was, well if someone is taking GABA and they have an effect, then there’s a potential for it to cross the blood brain barrier. And it was kind of following the theory of the lactulose mannitol test. So there’s patients out there who take GABA and nothing happens and some patients take it and go, “It was amazing. Best thing ever. It finally helped me sleep,” or, “Helped reduce anxiety for me.” So, one of the theories was that maybe for some of these people, their blood brain barrier is breached.

Now I know we talked and there is actually the possibility of other pathways that can impact GABA, maybe directly to the gut itself, through the vagus, so I don’t discount those possibilities because we still don’t know. I mean, ultimately, there’d have to be a study designed where they look at it. And it would have to be an animal study, there’s no way you can get an IRB for human studies to check if it’s crossing the brain. It’s some really advanced isotope tracing techniques and I just don’t think the level of dyes they would have to consume to look at the gut and the brain is peripheral and separate… it wouldn’t be possible. So the real answer is, we don’t know.

For me, I still am always suspicious if someone takes GABA and they have a reaction. I always want to go and check the blood brain barrier. And it’s not 100%, I mean, I can tell you without question, there’s people who take GABA, you do a blood brain barrier test, they feel benefit from it, but their blood brain barrier doesn’t have any markers to show permeability.

So it’s not hard for me to consider the possibility that there’s some exogenous pathways too. But at the same time, it’s also really hard to look at the molecular weight of GABA and look at what can cross a healthy blood brain barrier. This Dalton size, we’re talking nanoparticles to a huge, huge particle. So I don’t know but I think we’ll just have to see what happens. And ultimately, if you feel better with GABA, that’s great. If it’s not harmful to you, and if you feel like taking it, that’s great.

I like to also use things like Valerian root, passion flower, and hops because those compounds cross the blood brain barrier. They cross the blood brain barrier and they bind to GABA receptors.

So, the other thing too with actually using GABA you always have the potential for your neurotransmitter receptor sites to down regulate. And this is seen all the time too, patients take GABA and they feel great and then they have to increase their dose and they don’t get the effect as they first did. And they increase the dose and finally, they just don’t get much of an effect from it. And that’s potentially due to receptor site down regulation, which is not as common if you take agonists like Valerian root or passion flower, or hops. These things bind to GABA receptors. So I did a review in my book, where I went over all the literature of the different GABA compounds, which have been published in the literature.

But I’m not going to deny the possibility that there is a potential exogenous source but I also can’t let go the possibility that the blood brain barrier is permeable. So I’m still waiting.

Trudy: Yes, I think it’s great because the fact that you write about that and you taught about that, and you teach about it. It got me looking into the research further and it got me more curious; and it’s good, it’s good to have a healthy discussion and a healthy debate, and be open to possibilities. I’m very open to having my mind changed if something comes up.

I just see GABA works so well with my clients and we use very, very small amounts. I know with your GABA challenge, it’s… what is the amount, its 1,500 milligrams, I think or 1,500 to 2,000? So I’ll start my clients on 125 milligrams of GABA sublingually and get results. I have not noticed the effect that they need more and more, and more. So that’s interesting that you say that. But yeah, it’s good, I’m glad that we’ve had this discussion.

And the other thing that you did say in the online discussion, you said, if someone has a response to taking oral GABA, in other words, taking a GABA supplement does help them, you would want to test for the blood brain barrier permeability, just to see what’s going on. And I like that you say we can track. I’ve actually been in discussions with Cyrex and said, “Hey, why don’t we monitor people who are doing the Cyrex test and have a response to GABA, either therapeutically for the anxiety or with your challenge?” We may start to see some patterns, which I think would be very interesting.

Dr. Kharrazian: Yes, the best we can do with the data in that scenario is just the correlation statistical analysis. But it still wouldn’t answer it.

Trudy: No, I know. But maybe that will trigger someone to want to do a study. So, the good news is we’re seeing more and more research on GABA in the literature. So, it’s exciting. Well, thank you for discussing that with me.

You can read more from our very enlightening interview here: Fix the Brain to Fix the Gut. Dr Kharrazian covers the impact of brain injury and impaired vagal activity (as well as motility and breakdown of the blood brain barrier), how to activate your neurons, using polyphenols for neuroinflammation and butyrate for leaky gut/brain.

These blogs have additional information on GABA and some of the many possible mechanisms:

Here are some blogs with feedback from folks who have benefited from using sublingual GABA for dental anxiety, ADHD/focus issues and Lyme anxiety:

The best way for you to figure out if you will benefit from GABA is to use the trial method. Do the low GABA questionnaire and do a trial of GABA (used sublingually), starting low and increasing until you find the right amount to ease anxiety and improve sleep. You can find the GABA products I recommend on my supplements blog.

Please do share if you’ve benefited from using GABA or if you use it with success with your clients or patients.

GABA and theanine for easing anxiety, improving sleep and supporting immunity

By Trudy Scott 86 Comments

gaba theanine

Stress and anxiety suppresses immunity and so does poor sleep. One root cause of anxiety and poor sleep can be low GABA (gamma-aminobutyric acid) levels.  When you boost low levels of GABA (the neurotransmitter) with the amino acid GABA (it has the same name as the neurotransmitter) or theanine (another amino acid), you feel calmer and you sleep better, and you indirectly support your immune function too. We also have research that directly supports the role that GABA and theanine may play when it comes to improving immune function.

This paper, Psychological Stress, Immunity, and the Effects on Indigenous Microflora, describes the field of PsychoNeuroImmunology which

has clearly demonstrated that the physiological response to psychological stressors can dramatically impact the functioning of the immune system, thus identifying one way in which susceptibility to or severity of diseases are exacerbated during stressful periods.

It’s important that we keep all this in mind as we deal with the coronavirus pandemic and during other times when we may be exposed to infections.

The authors also share that psychological stressors impact the microbiome contributing to increases in markers of inflammation even when there is no infection. As you may recall from the recent Anxiety Summit 5: Gut-Brain Axis there is a bidirectional communication between the gut and the brain, with poor gut health having a direct impact on anxiety levels.

The sleep-immunity connection

Here is some of the research supporting the sleep and immunity connection:

Sleep is considered an important modulator of the immune response. Thus, a lack of sleep can weaken immunity, increasing organism susceptibility to infection.

Sleep abnormalities affect immune function in a reciprocal manner, leading to changes in proinflammatory cytokines, such as tumor necrosis factor, interleukins 1 and 6, and C-reactive protein. The multitude of systems that react to sleep loss suggest effects beyond the central nervous system and include total body functioning.

The GABA and theanine anxiety-immunity connection

Here is some of the research supporting the more direct role GABA and theanine may play when it comes to immune function (and act as a relaxant and anti-stress nutrient at the same time):

GABA could work effectively as a natural relaxant and its effects could be seen within 1 hour of its administration to induce relaxation and diminish anxiety. Moreover, GABA administration could enhance immunity under stress conditions.

A number of recent studies have suggested that theanine administration can improve the body’s immune system….one particular study highlighted the use of theanine as an intervention to decrease the incidence of upper respiratory tract infection symptoms via enhancing gamma and delta T-lymphocyte function.

The authors cite one study where “administration of 200 mg theanine was found to have an “anti-stress” effect on pharmacy students” and “regulate dopamine and serotonin levels in the brain through the release of the inhibitory neurotransmitter GABA.”

The  low GABA type of anxiety

When you have the  low GABA type of anxiety you’ll feel physically tense and overwhelmed, fearful and not be sleeping well. You may lie in bed stiff and tense and may also have unwanted thoughts and experience monkey-mind. It’s common to self-medicate with alcohol to stay calm or you may also use carbs to relax. When you use the amino acid supplement GABA, you get quick and very effective relief – when it’s used sublingually.

Already using GABA/theanine or have used it in the past?

If you are already using GABA or theanine you may find you need extra during this time of added stress.  You don’t want to make the mistake of thinking “This is serious, I need to double-up.” The best approach is to monitor your low GABA symptoms and consider using an extra dose during the day or possibly more at night or possibly more at each dose. Use the trial method to monitor your response.

Someone in my facebook community said she was conserving her GABA and noticed her anxiety was creeping back up. Now is not the time to cut back on GABA.

If you’ve found benefit from GABA or theanine in the past but are not currently using it you may very likely feel the need for the additional support right now.

New to low GABA anxiety symptoms and using GABA/theanine?

If you suspect low GABA symptoms and are new to using the amino acids and do not have my book I highly recommend getting it and reading it before jumping in to taking supplements: The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings. (get it out of the library if you’re watching your expenses.)

There is a complete chapter on the amino acids and one for pyroluria, plus information on real whole food, sugar and blood sugar, gluten, digestion and much more.  If you’re not a reader there is now also an audible version.

Here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution and additional information on Anxiety and targeted individual amino acid supplements: a summary

Please also read and follow these Amino Acid Precautions.

This lists The Antianxiety Food Solution Amino Acid and Pyroluria Supplements that I use with my individual clients and those in my group programs.

In summary, anxiety and sleep deprivation are not good for your immunity, and theanine and GABA can ease anxiety, improve sleep AND enhance immunity.

Please share your experiences with GABA and theanine and feel free to ask questions. Let us know if you were aware of the connections to immune function and if you’ve noticed your immune system is stronger when using GABA or theanine?

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

By Trudy Scott 46 Comments

theanine for anxiety

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

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

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

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

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

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

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

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

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

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

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

Some of the reported possible mechanisms of action

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

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

Impacts on cortisol levels?

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

Update Sept 2025:

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

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

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

Theanine or GABA – which one to use when?

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

I recently reached out on facebook asking:

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

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

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

Some of my top GABA/theanine products

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

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

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

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

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

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

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

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

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

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control (this is covered in an entire chapter too), sugar cravings, anxiety and mood issues. The importance of quality animal protein and healthy fats is also covered.

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

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

If you need serotonin support, the Serotonin QuickStart Program is a good place to get help. This is also a paid online/virtual group program where you get my guidance on using tryptophan and 5-HTP safely, and community support during 5 LIVE Q&A calls. You can sign up to be notified when the next live launch of this program is happening.

If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. This is also a paid online/virtual program with an opportunity to interact with me and other practitioners who are also using the amino acids.

Now I’d love to hear from you

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

How high to go on GABA for sleep issues and what are the negative effects of too much tyrosine?

By Trudy Scott 12 Comments

gaba and sleep issues

How high to go on GABA for sleep issues and what are the negative effects of too much tyrosine?

Today I’m sharing a great question I received about sleep issues – how high to go on GABA and what are the negative effects of too much tyrosine – together with my feedback because it’s not always a simple answer.

Here is the question about sleep, GABA and tyrosine:

I find I need more than the 500mg of sublingual Gaba Calm for sleep even with 200mg theanine. What dose can I go up to. Took a while to work up to that dose. I want to get away from sleeping tablets. Also what are the negative effects of too much tyrosine that comes with this product?

GABA Calm contains both GABA (125mg) and tyrosine (25mg) and it’s one of my most recommended products for anxiety. It sometimes works for insomnia and sometimes it doesn’t.

GABA and feeling stiff and tense with insomnia and anxiety

As you may know, with sleep issues caused by low GABA levels you’ll often lie awake with feelings of physical tension and stiff muscles rather than the ruminating thoughts which is the low serotonin type of insomnia – although it’s not uncommon to experience both. You may also have the stiff-and-tense type of anxiety, panic attacks and the need to self-medicate to calm down, often with alcohol but sometimes with carbs and sugary foods. By using the amino acid GABA you can raise your GABA levels and ease many of these symptoms.

Tyrosine can be stimulating and can be calming

Tyrosine is a considered a stimulating amino acid that is the precursor for making catecholamines (one of the neurotransmitters) like dopamine, epinephrine and norepinephrine. Boosting these neurotransmitters provides focus, increased energy and more motivation, and can also alleviate some forms of “curl-up-in-bed” depression.

Conversely tyrosine can also provide a sort of calm focus for some folks.

How much GABA and how much tyrosine?

Keeping all the above in mind, here is my feedback: 500mg of GABA is a large dose when starting out and is typically too high for most people, causing a light-headed feeling and sometimes a niacin-like flush. For this reason, it was good to hear that she worked up to that dose of GABA, found in 4 of the GABA Calm tablets i.e. 125mg of GABA for each one.

When my clients get up to multiple GABA Calm tablets I will often have them switch to a GABA-only product or a GABA/theanine product (opened up onto the tongue and held there for 2 minutes or longer) as the tyrosine can be stimulating. Some folks do fine on a small amount of tyrosine in the evening so 1-2 GABA Calm may be fine but more than that and it can be too much and may need to be avoided.

Taking 4 x GABA Calm tablets also provide a hefty dose of sugar alcohols which could cause diarrhea.

As far as using higher amounts of GABA, I have clients increase as long as they are seeing added benefits. I have had some clients go up to 1000-2000mg but more than this is rare. Theanine can often also be increased up to around 1000mg.

Here are some clues to look out for:

  • too tired in the day → too much GABA or too much theanine?
  • too tired in the day → too little GABA or too little theanine causing disturbed sleep?
  • too tired in the day → not enough tyrosine?
  • not able to sleep well → too little GABA or theanine?
  • not able to sleep well → too much tyrosine (at night or even mid-afternoon)?
  • calm energy → just enough tyrosine
  • sleep well → just enough GABA and/or theanine

There is research supporting that a GABA/theanine combination can improve sleep and that a GABA/5-HTP combination can too. There is no research on GABA Calm and insomnia but in practice it works for some people at night and not for others.

I’m sure you can agree with me that it’s not always simple and there can never be one size fits all. This doesn’t work: “Since you have insomnia take 2 GABA Calm and I’ll see you in a month” or even “This 250mg GABA with 100mg theanine will sort out your sleep issues in no time.”

It’s always a matter of figuring out what your own unique needs are.

Looking for other root causes of your insomnia

If my clients are not seeing incremental benefits as they increase the GABA and/or theanine (and stop the tyrosine) they go back down to their lower dose and we start looking for other root causes for their insomnia.

These root causes can range from low serotonin to high cortisol, also gut issues like SIBO, parasites (which are more active at night) or gluten issues. Too much caffeine (even if consumed in the morning and even a single cup of coffee!) and low blood sugar must always be ruled out too. Some sleep medications can actually make sleep worse especially benzodiazepines. And side-effects of all medications need to be looked at and also the possible effects of EMFs/WiFi.

Have you found that using the trial method with GABA and/or theanine has enabled you to find the ideal amount to take for your insomnia or anxiety? Where did you start and how high did you need to go and how much did this approach help?

Did the removal of tyrosine make a difference or make you more tired in the day?

Were there other factors at play as root causes of your insomnia or anxiety?

As a practitioner, do you want to learn more about how to incorporate GABA and theanine and the other targeted individual amino acids, tryptophan/5-HTP, DPA, glutamine and tyrosine, into your work to help your clients/patients with sleep issues and anxiety?
