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

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?

IMMH highlights: mold, oxalates, anxiety, panic attacks and depersonalization

IMMH highlights

Today I’m sharing some highlights from three different presentations at the recent IMMH/Integrative Medicine for Mental Health Conference – on mold and the connection to oxalate issues, as well as a major trigger of anxiety, panic attacks, depression and depersonalization.

Matthew Pratt-Hyatt, PhD: “The Hidden Threats of Mycotoxins.”

Matthew Pratt-Hyatt, PhD presented on “The Hidden Threats of Mycotoxins.” He shared medically significant mycotoxins and that ochratoxin affects the kidneys and my first thought was: “I wonder if this plays a role in oxalate issues?”

I asked Dr. Pratt-Hyatt after his presentation and he said yes, the mycotoxins produce oxalates and then dietary oxalates can be the tipping point. He wasn’t aware of any research on the mycotoxin-oxalate connection but sees the connection on the Great Plains MycoTOX lab test and Organic Acids test

Dr. Neil Nathan: “Mold Toxicity as an Unrecognized Cause of Mental Health issues.”

One of my favorite presentations was the one delivered by Dr. Neil Nathan on “Mold Toxicity.” He defines mold toxicity and how it can directly trigger anxiety, panic attacks, depression, depersonalization and hallucinations, as well as some of the common complications which can exacerbate mental health symptoms. These include mast cell activation, multiple chemical sensitivities, secondary porphyrias, methylation dysfunction and pyroluria.

I do appreciate the fact that he addressed that there can be PTSD caused by physicians when someone knows they are sick – especially with mold toxicity – and yet they do not feel heard or validated. This can even lead to their families being less supportive.

Dr. Nathan is a brilliant and compassionate practitioner, and the author of the excellent book – Toxic: Heal Your Body from Mold Toxicity, Lyme Disease, Multiple Chemical Sensitivities, and Chronic Environmental Illness (my Amazon link)

Dr. Kurt Woeller: “Metabolic Products in Mental Health – How Fungal, Bacterial, Mitochondrial and Other Compounds Influence the Brain.”

Dr. Kurt Woeller shared more about oxalates and mold in his presentation: “Metabolic Products in Mental Health.” I really like the Oxalate Metabolism diagram that shows the role of low vitamin B6, dietary oxalates including ascorbic acid, collagen and gelatin, mold, yeast and genetics in someone with high oxalates.

On a side note, low serotonin is often a factor with collagen and gelatin but it can be a source of oxalates.

He mentions various health problems associated with high oxalates – pain issues are common and so is fatigue and behavioral issues. Dr. Woeller works primarily with children but I have seen anxiety and depression in adults with oxalate issues too.   If mold is one of the triggers then the mental health issues can be further impacted.

 

In case you missed the previous two IMMH blogs:

What wasn’t discussed were some of the other mechanisms that may be causing the increased anxiety – such as the impacts of toxic mold on neurotransmitters and low levels of zinc.

Have you been exposed to toxic mold and was this a trigger for your anxiety, panic attacks and other mood issues?

Did GABA, tryptophan and zinc (and other nutritional support approaches) help ease some of the anxiety symptoms while you were remediating your home and detoxing from the mold toxicity?

Do you have oxalate issues and have you ruled out the fact that toxic mold may be a trigger? I personally have oxalate issues (I share more about this here) and plan to do the MycoTOX test to learn more. I’ll keep you posted on what I find.

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

I’m back from 2 weeks in the USA, first attending the Mindshare Summit (a collaborative community of like-minded practitioners) and then speaking at the IMMH/Integrative Medicine for Mental Health Conference – my favorite mental health conference – on “GABA for Anxiety, Insomnia, ADHD, Autism and Addictions: Research and Practical Applications.”

Last week I shared a blog on one of the new studies in my presentation: how a combination of GABA and theanine improves sleep and reduces anxiety. Today I’m sharing some other highlights from my presentation: benzodiazepines are not the solution, some new 2019 research on the far-reaching benefits of GABA, and the role of GABA in ADHD.

GABA, 5-HTP and melatonin isn’t working anymore for my insomnia and tryptophan gives me a migraine – what should I do?

By 20 Comments

Today I’m addressing a great question I received on a recent tryptophan blog about insomnia and the use of the amino acids GABA and 5-HTP in a combination product together with melatonin, and what the next steps should be when you are not getting the expected results. And if continuing with tryptophan is a good idea when it seems to be causing a migraine and isn’t leading to a whole night’s sleep. Here is the question:

I have suffered from insomnia for most of my life. I just got your book and am loving it! Thank you for all that you do. My symptoms seem to be high for both low GABA and low serotonin [here is the questionnaire].

I also believe I have a blood sugar problem, so I’m starting to follow your suggestions for that.

I’ve been taking a supplement for sleep that has both GABA and 5-HTP in it, along with melatonin. It worked for a year, however it just recently stopped working.

I thought maybe I should try tryptophan. After taking only 220 mg per night, along with 5 mg of melatonin, I was able to sleep, but not through the entire night. However, the next day I woke up with a horrible headache/migraine. I know it was the tryptophan because I did a trial and tried a night without it and then again with it and the nights I took it, sure enough, the migraine would return.

I must add that I had bloodwork done and tested low for melatonin, which is why I was adding the melatonin into my protocol.

My question is: do I continue with a higher dose of GABA, 5-HTP and melatonin, since it worked for a year i.e. do I up the dosage of the supplement I’ve been taking? Or do I continue trying different doses of tryptophan?

I shared this response in my comment (with some additions for this blog post).

Always first address the nutritional foundational aspects

Firstly, I was glad to hear she is loving my book The Antianxiety Food Solution (my Amazon link) and implementing dietary changes. This is so foundational to any protocol for both anxiety and insomnia. Too often, someone hears me talking about the amazing amino acids and forgets the nutritional basics of real whole food, quality animal protein (like wild fish, pastured eggs and chicken, grass-fed red meat), organic veggies and fruit, healthy fats (like olive oil, coconut oil and butter), fermented foods and broths, and no gluten, caffeine or sugar.

I don’t ever have clients push through

With regards to her trial of tryptophan I shared that I don’t ever have clients push through on a product that is causing any adverse effects, and especially when it’s a migraine. She was smart and trialed the tryptophan twice to make sure it was the tryptophan that caused the migraine and not something else.

Capitalize on what has worked and increase one at a time

With regards to the GABA, 5-HTP and melatonin I shared that I always like to capitalize on what has worked in the past (or is currently working) and would rather increase the 5-HTP and/or melatonin and/or GABA one at a time.

Notice that I said increase these products one at a time. She is taking a combination product so it’s impossible for her to do this. Maybe her GABA levels are now good (because her progesterone levels have improved due to be on a regular zinc supplement or because she has been doing regular yoga sessions) and maybe she needs more serotonin support (because her estrogen levels are off because of recent exposure to xenoestrogens in plastics).

Even though is research showing that a combination product containing GABA and 5-HTP improved sleep and sleep duration more than the use of either of the two amino acids alone, based on her feedback, if we were working together I would have her do each of the GABA, 5-HTP and melatonin separately. This way it’s easy to mix and match and increase one and possibly lower the other, until the ideal combination is found for her unique needs at this time in her life.

She may even find she only needs GABA or only needs 5-HTP or only melatonin. She may also find she needs sublingual melatonin for helping her fall asleep and timed-release melatonin for helping her stay asleep.

She mentions the amino acid questionnaire so it sounds like she is clear on her symptoms: low GABA physical anxiety affecting her sleep and low serotonin mental worry-type of anxiety affecting her sleep. So as she trials the individual amino acids she can see how she does symptom-wise in order to find the ideal amount.

Other factors to consider with insomnia

It’s often straight-forward with the amino acids and the great thing is that one you have the correct combination you will see results in a few days to a few weeks. But There are other factors we may need to consider with insomnia:

  • Keep in mind that 5-HTP can raise cortisol and low blood sugar can indicate adrenal issues so looking at high cortisol as a factor in the sleep problems would be something to consider. A 4-collection saliva test will measure this and my favorite product for lowering high cortisol is Seriphos. Other nutrients for adrenal support may be needed too.
  • Just addressing low blood sugar can often improve insomnia. Eating to support blood sugar swings, early morning sunlight and no blue light after dark can make a world of difference.
  • Other sleep factors we always want to consider: sex hormone imbalances, parasites (they are more active at night and can keep you awake and play a role in high cortisol), accidental gluten exposure, SIBO (small intestinal bacterial overgrowth), candida, sleep apnea and mouth breathing, EMFs (WiFi in the home, commuting with the iphone on, a new cordless phone etc.) and medication side-effects (benzodiazepines are a common one).

I really appreciate questions like this being posted on the blog so others like you also get to benefit. This question also demonstrates just how our needs for certain nutrients can change over time and how we may to keep adjusting what we are doing.

In case you have questions about specific products that I use with clients, here is my supplements blog and more information on GABA for the physical type of anxiety and 5-HTP/tryptophan for the worry-type of anxiety.

Can you relate to this scenario? Feel free to ask your questions about sleep, GABA, 5-HTP, tryptophan and melatonin and share your experiences with these products and how they have helped you or if you’ve had issues with any of them.

GABA oral rinse reduces burning mouth pain

By 47 Comments

Burning Mouth Syndrome (BMS) is a chronic pain condition characterized by persistent burning in the mouth. It affects mostly females, especially postmenopausal women, and conventional approaches are often not very successful. You’ll often see articles and papers with the terms ‘refractory’ and ‘unknown etiology’/unknown causes.

Medications like SRNIs and benzodiazepines

Some studies report limited success with medications like venlafaxine/Effexor, an SRNI and topical and oral use of benzodiazepines such as clonazepam/Klonopin. In this paper, Refractory burning mouth syndrome: clinical and paraclinical evaluation, comorbidities, treatment and outcome, 8 participants saw their pain diminish by half within 3 months.

Another paper, The Effect of Clonazepam Mouthwash on the Symptomatology of Burning Mouth Syndrome: An Open Pilot Study, reports success with a benzodiazepine mouthwash in half the participants.

Other than the poor quality of life and having to continue to live with pain, the bigger concern is the side-effects of medications like these, plus concerns with tolerance and then issues with withdrawal.

New oral GABA research for burning mouth

It’s for this reason that I’m excited about the recent research, γ-Aminobutyric acid (GABA) oral rinse reduces capsaicin-induced burning mouth pain sensation: An experimental quantitative sensory testing study in healthy subjects, that finds that both and men and women experienced immediate benefits when using GABA for burning mouth pain.

The burning mouth pain was caused by the application of capsaicin to the tongues of thirty healthy males and females. Capsaicin is the compound that makes chili peppers hot. (I find it interesting that capsaicin was the compound used to cause the burning mouth sensation because this same compound is used in topical creams and patches to ease pain.)

The study concludes as follows:

Capsaicin-induced burning tongue pain and decreases in WDT (warm detection) and HPT (heat pain) can be ameliorated by rinsing the mouth with lidocaine and GABA solutions.

Rinsing the mouth with an oral GABA containing solution ameliorated burning pain and increased heat sensitivity produced by application of capsaicin to the tongue. This finding suggests that GABA can act as a local analgesic agent in the oral cavity.

Lidocaine, a numbing medication, was part of the GABA solution in this study, but because it has side-effects that may include anxiety, I recommend a trial of a GABA-only solution to ease the burning mouth pain.

Using a GABA-only oral solution

Using a GABA-only oral solution makes sense given that the likely mechanism of action of topical benzodiazepines in burning mouth pain is via local action on peripheral GABAA receptors found in the nerve fibers of the tongue.

This is also very feasible based on how effective GABA is for other pain such as proctalgia fugax/rectal spasms, and the visceral pain and muscle tension in your gut caused by the bloating symptoms of SIBO (small intestinal bacterial overgrowth) and muscular back pain after a fall.

How much GABA will help?

As with any use of GABA and the other amino acids, how much will help depends on each person’s unique biochemistry and needs at the time. In the same way I do a trial of GABA with my anxiety clients to determine how much would help, I do the same with burning mouth pain (and other pain situations).

I recommend a trial of a GABA-only product and starting low with 100 to 200mg of GABA swished held in the mouth with some water for a few minutes. This can be used three or four times a day in between meals and with the mg increased slowly based on results.  You can find the GABA supplements I recommend here.

GABA is an amino acid that is recognized for calming physical anxiety and tension and since anxiety (and depression) is very common in those with burning mouth pain, the GABA is going to provide calming benefits too.

As with any health condition, finding the underlying root causes using a comprehensive functional medicine approach is key. One such root cause may be low GABA and using oral GABA is going to address this one and provide some relief while other root causes are identified and addressed.

These other root causes can be very varied as explained in the paper Burning Mouth Syndrome. They can include: age-related reduction in estrogen and progesterone levels, lower cortisol, diabetes mellitus and hypothyroidism, allergic reactions to foods, additives and even metals in the mouth, autoimmune connective tissue disorders, nutritional deficiencies (B1, B2, B6, B12. folate, and/or zinc), smoking and candida, and medication side-effects as mentioned above.

Have you experienced burning mouth pain and seen relief with GABA or other nutritional approaches?

If you’re a practitioner, is burning mouth pain common in your postmenopausal clients or patients and what approaches have you found most successful? Have you found GABA to be helpful?

If you are still suffering with burning mouth please share the following when you comment:

  • Your age (it seems to be more prevalent in women 59 and older)
  • If you have anxiety and/or depression now and have been prone to either in the past
  • How you score on the low GABA questionnaire and which symptoms you relate to? This will provide a clue that low GABA may be an issue and the oral GABA rinse is more likely to help
  • How you score on the low serotonin questionnaire (same link as GABA questionnaire above) and which symptoms you relate to? SSRIs have been shown to help in some cases and we know tryptophan/5-HTP help with pain so serotonin support may help too. Perhaps a tryptophan or 5-HTP rinse is worth a trial too?
  • How long it’s been an issue, what approaches you’ve tried and which approaches have helped (even if they only helped a short while or helped the pain a little)
  • Current and past medications (burning mouth is caused by certain medications)

I’d love to gather a list of all this so we can help you and more women who suffer with these awful symptoms.

Alzheimer’s disease: address the root cause to reverse symptoms (Microbiome summit)

By 4 Comments

Dr. Jill Carnahan’s interview on the Microbiome Medicine Summit 2 covers cutting edge new information about Alzheimer’s disease, based on the work and research of Dr. Dale Bredesen. They start with the gut-brain connection and Dr. Carnahan shares this:

we used to think of early-onset cognitive decline and dementias and mood disorders as being in their own bucket. And so, we saw psychiatrists or neurological doctors or neurologists to treat those diseases. And now we’re finding as we knew for several years with functional medicine that, obviously, it’s all connected.

And the gut is especially important because this reservoir holds so many of our microbes and possibly pathogens and that speaks to the brain through the vagus nerve and through cytokines and through inflammatory molecules of all types.

And so, this conversation between our gut and our brain is very profound and has a huge impact on things like multiple sclerosis or dementia, Alzheimer’s, or even things like bipolar disorder, schizophrenia, depression, anxiety, and sleep disorders.

So what we’re finding is by addressing the immune system and the gut which are intricately connected, we can often get profound effects on areas in the body that are far from that, like the brain.

Dr. Kellman asks Dr. Carnahan to share a study that will be the slam dunk for really believing in this connection and she mentions a paper titled Microbes and Alzheimer’s Disease. It cites pathogens like herpes simplex virus type 1 (HSV1), Chlamydia pneumoniae, and several types of spirochaete which can affect the brain and play a role in Alzheimer’s disease.

Dr. Carnahan then covers Dr. Dale Bredesen’s subtypes of early-onset dementia which allows you to treat the root cause and actually reverse symptoms. She goes into it in great detail so I’m going to give you the summary version here:

Type #1 is inflammatory

  • This could be from inflammation or infections or other poor dietary habits. And that’s where the microbiome could play into that.
  • You might see elevated CRP, IL-6, TNF-alpha. You might see a low albumin to globulin ratio. You might see high homocysteine, hypothyroid, elevated cortisol

Type #1.5 is glycotoxic

  • The pure pre-diabetic, diabetic
  • That’s kind of the pure elevated insulin, elevated fasting blood sugar, elevated cortisol, low testosterone, high triglycerides, low HDL (and has an element of inflammation)

Type #2 is atrophic: So that’s someone who loses their trophic factor of support like estrogen, testosterone, insulin, and vitamin D3.

And often, these type 1s and type 2s actually have ApoE-4 double mutations which are higher risk for Alzheimer’s.

Type #3 is toxic:

  • Toxic mold exposure, biotoxins from Lyme disease, or heavy metals or other chemicals.
  • Often these chemicals will act on the tight junctions of the gut and increase permeability. And then that permeability leads to massive endotoxemia.
  • Younger onset of symptoms (like 40s and 50s) and reversible once you find and remove the root cause

Type #4 is vascular: inflammation of the blood vessels, high homocysteine

Type #5 is traumatic: wrestlers or boxers or football players that have had multiple head injuries or trauma.

By addressing the various root causes, Dr. Bredesen reports a reduction and in some instances reversal of dementia symptoms.

Of course, we know anxiety is common when it comes to Alzheimer’s and dementia. By addressing many of these above root causes we’re also able to reduce anxiety symptoms at the same time.

It was a fascinating interview and I hope you enjoy it as much as I did. I learned a great deal and find it very useful to group the symptoms into types.

There does seem to be one aspect that Dr. Carnahan didn’t address and I haven’t seen it covered in Dr. Bredesen’s papers: the impact of benzodiazepines on dementia and Alzheimer’s disease.  There is conflicting research on this but I feel there is enough research that does show a correlation – enough for us to be concerned.   Here is a recent paper looking at high-dose benzodiazepine use in Chinese patients , supporting an association.

This 2016 paper – Benzodiazepine Use and Risk of Dementia in the Elderly Population: A Systematic Review and Meta-Analysis states:

Our results suggest that benzodiazepine use is significantly associated with dementia risk. However, observational studies cannot clarify whether the observed epidemiologic association is a causal effect or the result of some unmeasured confounding variable. Therefore, more research is needed.

This may likely fall under type #3 (toxic).  I plan to reach out to them as a follow-up.

UPDATE: May 9, 2017.  I did hear back from Dr. Carnahan and she shared that she always discusses history and physical and lab testing, and history of benzodiazepine use or other neuroactive substances. 

And new research shows that it’s more than the benzodiazepines: SSRIs, SRNIs and atypical antipsychotics increase the risk of dementia in veterans with PTSD and even in those who don’t have PTSD. 

I hope you’ll join the host Dr. Raphael Kellman and all the great speakers on the Microbiome Medicine Summit 2, May 8-15, 2017 to learn more.

If you have questions or comments please feel free to share in the comments.
