Headaches

BeSerene™ GABA/theanine cream eases severe muscle tension in her neck/shoulders, prevents her bad headaches and quells her anxiety

October 24, 2025 By Trudy Scott 9 Comments

Hi there… I wanted to add my ‘two cents’ to the discussion about the BeSerene™ GABA/theanine product that you recommend. I LOVE it! I suffer from low GABA levels, which result in my having severe muscle tension in my neck and shoulders. Often, that resulted in bad muscle tension headaches, for which I couldn’t find anything to bring relief. The BeSerene™ GABA/theanine cream has been a real game changer.

If I wake up with one of those headaches in the middle of the night or in the morning, I use two pumps and rub it on my tight neck and shoulder muscles and within 15 minutes, I can feel the tension melting away! It literally goes away! I have even been able to prevent a headache from occurring by using it on my neck muscles before I go to bed at night.

Insofar as anxiety, I get relief from that as well, because generally I start to get anxiety once the headaches start, as I never know if it is going to be manageable with just an ibuprofen or two, or if it is going to be one of ‘those’ headaches, i.e. a migraine that lasts for a day or more! Unfortunately, once the anxiety starts, it makes the muscle tension headache worse, which makes the anxiety worse, and it’s just a horrible vicious cycle!

So, since the BeSerene™ cream works so efficiently on the muscle tension, it quells the anxiety that usually follows!

It has changed my life, and I don’t know of any other product I can say that about. I can honestly say that I will not allow myself to ever be without it now!

Thank you so much Trudy, for recommending this product!

Lisa is a woman in the community who reached out to me via email with this message raving about how life-changing this cream has been for her. I am thrilled for her and never get tired of hearing results like this. I’m not surprised either and love to share these kinds of results! She kindly gave me permission to share, saying “I want others to experience what I have with this product!”

Read on below for more about why she gravitated towards using a cream, other benefits you may expect to see (like a reduction in stress-eating and/or drinking too much wine), my insights into when to consider using a GABA/theanine cream like this and how to use it, where to purchase this exact cream and additional resources if you are new to using GABA.

Why did Lisa gravitate to using a GABA/theanine cream?

Lisa shared that she just couldn’t seem to tolerate the sublingual or oral GABA:

I have tried sublingual GABA products but haven’t had much success, as I haven’t been able to find any without alcohol sugars (xylitol, sorbitol, etc.) Those ingredients give me a terrible taste in my mouth and I just can’t tolerate them. (Why can’t they make one with just real sugar from nature?)

Plus, I haven’t had a lot of success with the oral products as they just take too long to work on the headaches/muscle tension.

I’m really glad she recognized her symptoms were due to low GABA – muscle tension and pain, in conjunction with feeling physically anxious are common. And that she didn’t give up on GABA and persevered until she found what works for her symptoms.

What about other forms of GABA?

However, my advice for someone in Lisa’s situation is not to give up on other GABA products if she finds she needs additional support in the future or finds herself without the cream. With regards to taste and time to work, I recommend a GABA-only (or GABA/theanine) capsule opened on to the tongue or a GABA (and/or theanine) powder – both held on the tongue for 1-2 minutes for quick results.

Stress-eating and self-medication with wine are classic signs of low GABA

Interestingly, stress eating is not an issue for her but wine may be:

I’ve never really had any issues with stress-eating. In fact, I usually have no appetite when I’m stressed out! (That’s where the wine comes in…lol!)

We may self-medicate with wine when GABA is low because it relaxes us physically, helps us fit in socially and feels calming and pleasant. It’s mistakenly used to try and improve sleep but typically makes things worse.

Alcohol consumption damages the gut, depletes B vitamins (especially thiamine/vitamin B1) and zinc – and it’s addicting.

GABA can stop that addiction in its tracks so there are no feelings of deprivation. The reasons we are drawn to GABA are addressed too. And amazingly there is research that GABA may actually heal the gut after alcohol consumption.

Bumping up the GABA/theanine cream may help or considering one of the other GABA products mentioned above may be better.

Low GABA symptoms

As a reminder, if you are new to GABA, it’s an amino acid that helps to address low GABA levels and the associated symptoms: physical tension and feeling anxious, feeling worried or fearful, panic attacks, stiff or tense muscles, insomnia, feeling stressed and burned-out, craving carbs/alcohol for relaxation and calming, intrusive thoughts, spinning/poor focus, fear of heights, rectal spasms, burning mouth, and visceral pain/belly pain with IBS. See the most current list of low GABA symptoms here.

When to consider using a GABA/theanine cream like this?

These are some of the applications I consider

When other GABA products haven’t worked (like in Lisa’s situation)
When looking for something in addition to other GABA products, for example, GABA powder in the day while at work or play, and GABA/theanine cream at night for tension and sleep issues
When there is a specific need for a topical application – like with neck and shoulder tension or belly pain or period pain or leg spasms etc
For an aging parent with Alzheimer’s disease (and sundowning agitation/anxiety)
For a person with ARFID (avoidant-restrictive food intake disorder)
For a person with anorexia or other eating disorder
When a child or young adult has autism (with anxiety and sensorimotor issues), a child/adult who struggles with taking supplements and other special needs children/adults
For someone with multiple sclerosis (for anxiety and muscle spasms/spasticity)
When a person has severe digestive issues and prefers a cream
When someone just wants to take a break from sublingual/oral/powder GABA
For presurgery anxiety since supplements are typically not permitted (even though there is research showing both help)

Where to purchase BeSerene™ IR GABA and theanine cream and how to use it?

This cream can be purchased online with this link (this has my 15% discount built in – you’ll see the discount applied on the checkout page after you add it to the cart).

Purchase BeSerene™ IR

They recommend applying 1-2 pumps to your temples or wrists.

You could also use 1-2 pumps/squirts on your neck and shoulder (like Lisa did), the forearm or inner thigh (before bed for helping improve sleep), and/or belly (especially if belly pain or IBS/SIBO or PMS pain keeps you awake at night). It can also easily be applied if you wake in the night.

Personally, it’s a product I love at bedtime. I apply 2 pumps on my forearm and then rub my belly with any that is left over. It’s calming, improves my sleep and helps with belly pain at night.

I’m sure you can tell by now that this is a product I endorse. I recommend it to clients and to participants in my GABA Quickstart program. In fact, it’s one of the top ten GABA products I recommend and it’s even included in the training materials/handouts of the program!

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

We use the symptoms questionnaire to figure out if low GABA (indicating a possible need for GABA or theanine) or low serotonin (indicating a need for tryptophan or 5-HTP) or low endorphins (indicating a possible need for DPA) 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, 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). This is a paid online/virtual group program where you get my guidance and community support. We’ll be launching a budget-friendly homestudy version in a few weeks – sign up for the wait list here (the live version with Q&A is offered only a few times a year).

If you also 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…

I appreciate Lisa’s willingness to share her wonderful results. Now I’d love to hear from you.

Have you used BeSerene™ GABA and theanine cream and how has it helped you?

How does using a GABA/theanine cream compare with other GABA products you have used (feel free to share specific brands and how you used them – sublingual, capsule-opened, liposomal or powder or even another brand of GABA cream)?

As I shared above, some folks prefer a cream only and many use a combination of cream and sublingual.

Feel free to post your questions here too.

How the correct approach, dose and sublingual use of GABA can be calming and not cause a flushed and itchy face and neck

October 10, 2025 By Trudy Scott 12 Comments

I started GABA 750mg and think it gently chills out my anxiety a bit, however 20 minutes after I take it, I feel flushed and itchy in my face and neck. This lasts for 5 minutes and then goes away.

I am in a migraine program with a health coach who has referenced your book several times. She recommended I stop it because it sounds like an allergy. I personally would think it would last longer if it was an allergy.

What do you think? Have you heard of this reaction before? I thought it would maybe get better as my body gets used to taking it? I wanted to continue because I think it’s helping. Thank you.

Sharon posted the above feedback about her promising calming results with GABA and her flushed/itchy question on one of the blogs. She also asked this:

Just read other posts and I’m just beginning to learn all of this info on your site. I’m also getting your book. Looks like I may have started too high? Could I open up one of my capsules and just take powder orally and then work up?

Read on below to learn more about the fact that too much GABA does cause flushing; the correct approach, dose and sublingual use of GABA for Sharon; Holly’s similar story with 750mg GABA; and GABA, serotonin and endorphin support for Sharon’s other symptoms (headaches, migraines, PMS, sleep issues and rectal spasms); plus additional resources when are new to amino acids such as GABA, 5-HTP, DPA and others.

Too much GABA does cause a flush feeling

Firstly, it’s wonderful that GABA gently chills out Sharon’s anxiety a bit. And she is correct – her flush and itchy face and neck is unlikely to be an allergic reaction. Too much GABA does cause a niacin-like flush or tingling feeling and yes, I have heard of this reaction many times. Unfortunately it leads to many people giving up on GABA when they really do need it.

Sharon shared this: “I thought it would maybe get better as my body gets used to taking it?” Unfortunately, many individuals think the same and end up pushing through the discomfort and it’s not what I advise. She was wise in exercising caution and finding out by reading more on the blog, getting a copy of my book, The Antianxiety Food Solution and asking on the blog.

I have no idea why supplement companies produce such a high dose GABA product and it’s something I caution all my clients and GABA Quickstart program participants about.

The correct approach, dose and sublingual use of GABA for Sharon

Sharon also acknowledges she probably started with too high a dose and asks about opening up the GABA capsule and working her way up. This is exactly what we need to do to get results with GABA and not cause new issues.

Some other options to opening the GABA capsule could be:

a GABA only powder
a GABA sublingual product (such as GABA Calm)
a liposomal GABA product
a GABA cream (she reported migraines and neck tension so a cream may be a good option for her too)

I also have clients start with only one amino acid product and find the ideal dose before adding the next amino acid acid. And track results carefully so they can course correct, adjusting up or down as needed.

Sharon did come back and comment a week later sharing this adjustment she had made:

So I have been opening the GABA capsule and taking half a dose (so 375mg) on my tongue in the morning and then in the afternoon. I don’t notice the real calm like I did with the whole capsule though.

She’s on the right track and the next step could be to use three-quarters of a dose twice a day and see how that helps. Another option is half a dose, maybe 4 x day. There is no one-size fits all and it’s a matter of Sharon finding what works best for her unique needs.

Keep in mind that for some individuals even 375mg is too high a dose. I typically have clients start with 125mg GABA and less if they are super-sensitive.

Holly’s story with 750mg GABA is very similar

I’ve actually blogged about this before: Too much GABA causes a tingling niacin-like flush sensation (in the brain and body). It’s awful and very uncomfortable!) and shared Holly’s niacin-like flush result when using the same dose:

I experienced the niacin-like flush when I tried to go from GABA Calm [mostly dissolved in my mouth] to a pill form and didn’t realize the dosage would be way too high all at one time. The pill was 750 mg GABA [and swallowed with food], so it wasn’t going to work well anyway.

The flush lasted about 15-20 minutes. It was awful. I was sure I was going to throw up every time.

It took me a couple of weeks to figure out the cause. My therapist recommended your website and book and those helped me understand when to take it and why it would help.

When I eliminated the 750 mg GABA pill the symptoms completely went away.

Now I stick to GABA Calm. I take one in the morning and one before bed and sometimes one midday.

You can read more about this flush feeling on the above blog and another example.

GABA, serotonin and endorphin support for Sharon’s other symptoms

Sharon also has headaches, migraines, PMS, sleep issues and rectal spasms:

I’ve got chronic headaches and frequent migraines. Other weird symptoms are lip dermatitis, hormone imbalance, PMS, and rare rectal spasms which I saw referenced on your site too. Serotonin issues too and I also recently started 5-HTP 200mg at night which seems to be helping my PMS insomnia.

It’s great that 5-HTP is helping her PMS-related sleep issues. Both GABA and 5-HTP (for serotonin support) may help with her hormone balance, which in turn, may help with her headaches and migraines too. She may also want to consider a trial of d-phenylalanine/DPA for endorphin support/pain relief. GABA itself helps to ease neck tension and headaches.

GABA does stop very painful rectal spasms very quickly. More about this here – GABA lozenge relieves excruciating pelvic floor/rectal pain and spasms within 30 seconds: a solution for proctalgia fugax.

As I mentioned above, I have clients and those in the GABA Quickstart program start with GABA and find the ideal dose before adding the next amino acid acid. For Sharon, I’d recommend that she finds her ideal dose of GABA before bumping up her 5-HTP and adding DPA.

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

Now I’d love to hear from you…

I appreciate Sharon and Holly for sharing their experiences and asking questions. I’m hoping their stories have enlightened you!

And I am thrilled that her migraine health coach referenced my book and told her about GABA. It’s a great book that many practitioners share with their clients and patients.

Have you experienced this uncomfortable feeling when using too much GABA? And did you learn to use less in order to get the calming benefits of GABA?

How much do you find helps? And do you use powder or capsules opened or liposomal or cream?

Has serotonin or endorphin support helped too?

Glutamine for hypoglycemia/low blood sugar: “500mg mixed in water works in 15 minutes and keeps me going for 2 – 3 hours”

November 3, 2023 By Trudy Scott 27 Comments

Cat shared this feedback about how effective just 500mg of glutamine is for her low blood sugar and how quickly it helps:

I recently followed one of your posts on GABA down the rabbit hole to a linked blog post and then to another post where I found a mention of using glutamine for hypoglycemia. This is the only reference that I have read on this in 35 years of research on the subject. I follow a low carb, higher protein, healthy fat diet, but still suffer low blood sugar issues consistently at one particular time of the day. After so many years of eating a second breakfast to prevent the lows, I was ready to give any other healthy option a try.

It works!!! I found a powder that I mix approximately 500 mg of with water. It works within about 15 minutes and keeps me going for about 2 – 3 hours — long enough to reach a reasonable time for lunch.

I’m thrilled to have this option as anytime that I travel, low blood sugar becomes a huge issue as I suffer from ketotic hypoglycemia and end up with massive headaches and vomiting for 6-8 hours.

You have freed me from a huge weight! Thank you and hugs!

(And thank you for researching and sharing the tremendously helpful information in your books, webinar presentations and blogs.)

Thank you Cat for sharing your success and you are most welcome! I’m sharing this as a blog post because you may also be new to this.

Glutamine dosing, using powder vs capsules and using it on the tongue

Cat finds 500 mg glutamine works well for her unique needs. This is a good starting dose. I see many folks start too high, like 5000 mg / 5 g and up multiple times a day, and it’s not necessary. However, we increase based on individual needs and you may find you do need to use 500 mg -1000 mg two to three times a day.

Using a glutamine powder is a great way to use it especially if you find you do need more than 500 mg each time.

One thing I mentioned to Cat is when you use glutamine powder directly on to the tongue (rather than mixed in water), the benefits are seen more quickly i.e. right away rather than having to wait 15 minutes.

If you do start with glutamine capsules, be sure to open the capsule on the tongue too, But watch for fillers which can be irritating to some folks. Powders are typically glutamine-only and don’t taste bad at all. But when traveling, capsules may be a better option (at least when on a plane).

Ketotic hypoglycemia, adrenal dysfunction and breakfast

Ketotic Hypoglycemia International defines ketotic hypoglycemia as “a condition characterized by low blood sugar (glucose) and elevated ketones, typically occurring after fasting, like sleeping overnight. Ketotic hypoglycemia (KH) is not a disease itself but rather a symptom or a clinical presentation that can occur as a result of various underlying conditions.” I’ve asked Cat if she is aware as to what is causing her ketotic hypoglycemia and I’ll report back.

I have also asked if she has had salivary cortisol testing done as adrenal dysfunction plays a role in all types of low blood sugar and will need to be addressed. This can take awhile to test and figure out nutritional support. Until then, glutamine is wonderful for preventing low blood sugar episodes.

I’m also curious what her breakfasts look like and will update the blog when I find out. Cat does mention that she follows “a low carb, higher protein, healthy fat diet” so I assume her first breakfast is a good one. But it’s always something to confirm. As you can see on this blog, Anxiety and Hypoglycemia Symptoms Improve with Diet Modification, a healthy breakfast is key for blood sugar stability and preventing anxiety.

Low blood sugar symptoms and all the ways glutamine may help

This is the blog she commented on: Glutamine for calming, intense sugar cravings, gut healing and low blood sugar

I share all the symptoms we see with low blood sugar:

Crave sugar, starch or alcohol any time during the day
Irritable, shaky, headachey – especially if going too long between meals
Intense cravings for sweets
Lightheaded if meals are missed
Eating relieves fatigue
Agitated, easily upset
Nervous, anxious, panic attacks

As you can see, in addition to helping with low blood sugar symptoms, glutamine has calming properties (low blood sugar can also cause anxiety and panic attacks), helps reduce intense sugar cravings (sometimes described as a demonic urge to eat all things sweet and also helps with healing a leaky gut. Be sure to read these two blogs I’ve linked to above.

Glutamine has also been researched to help with addiction recovery. In this blog, An amino acid supplement with DLPA, glutamine and 5-HTP eases alcohol withdrawal symptoms at an inpatient detoxification program, glutamine is paired with two other amino acids.

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

We use the symptoms questionnaire to figure out if low blood sugar may be an issue for you.

If you suspect blood sugar or 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 topic has an entire chapter), sugar cravings, anxiety and mood issues.

I really appreciate Cat for sharing her story and giving me permission to share as a blog.

Has glutamine helped you with low blood sugar/hypoglycemia? If yes, in what way has it helped – reduced anxiety, less sugar cravings (or other addictions), and not as irritable and cranky/angry?

And how much helps and how quickly? Are you using it on the tongue?

Has glutamine also helped with leaky gut?

If you’re a practitioner are you using glutamine this way with your clients/patients?

Beware! Too much licorice tea can cause hypertension even if you have low or normal blood pressure

October 6, 2023 By Trudy Scott 38 Comments

A 45-year-old woman presented to her general practitioner with a 4-month history of hot flushes, sweating and headaches. On examination, she was found to be hypertensive, and blood tests revealed mild hypokalaemia [low potassium].

While awaiting the results of further investigation into the cause of her elevated blood pressure, the patient conducted her own research and identified liquorice tea [licorice tea] as the potential cause of her symptoms. The patient had been drinking up to six cups of liquorice tea per day as a substitute for caffeinated tea and fruit-based infusions.

The patient immediately stopped consuming the drink and within 2 weeks her symptoms, hypertension and hypokalaemia, had entirely resolved.

This case report, Hypertension induced by liquorice tea, is eye-opening because this woman had always had low blood pressure and so she ignored the small print on the box that states “not advised for people with hypertension.”

I often see this caution about avoiding licorice if you have high blood pressure (hypertension). But I have yet to see a warning on a box of tea about the fact that licorice can actually cause high blood pressure with high consumption – even when your blood pressure is low or normal. I feel the latter aspect is not as well known, which is the reason for this blog.

I’m also sharing this case report and additional information because something similar has just happened to me (more on my story below).

Here are a few more facts about this patient’s case:

She went to her doctor “with a history of hot flushes, night sweats and headaches. These symptoms had started over the preceding 4 months. The patient suspected that her symptoms were due to the onset of menopause.”
Initially her blood pressure was 162/82 and “Repeat blood pressure measurement confirmed ongoing hypertension of 150/80 mm Hg”
“Blood tests demonstrated mild hypokalaemia” (i.e. low potassium of 3.3 mmol/L).
Two weeks after she stopped drinking the licorice tea, “repeat blood pressure measurement was 128/84 mm Hg and her hypokalaemia (and other symptoms) had resolved.”

I encourage you to read the entire published case report to get an understanding of the mechanisms of licorice mediating “its effect on blood pressure via the action of glycyrrhizin on the kidney.” And the impacts on sodium, potassium, aldosterone, cortisol/cortisone and blood pressure. I will add that this is one of many such case reports in the published research.

My story with elevated blood pressure after drinking Yogi Throat Comfort tea

As I mentioned above, I’m sharing this case report because something similar has just happened to me! I had been drinking Yogi Throat Comfort tea for just over a week to soothe my throat and help after my voice loss. It contains licorice root as well as slippery elm and other herbs.

My blood pressure is typically low at 110/80 or less (sometimes as low as 102/80) and last Friday it was 130/80 which is the highest it had ever been.

I didn’t make the connection to licorice right away because I had just flown internationally from Hawaii to Australia and we were sprayed with insecticide on the plane when we landed in Australia. We all had to sit there in the toxic soup for 10 minutes. (I’ll be sharing more about all this in a future blog).

I suffered severe vertigo the next day and it was at the doctor’s office that I found out my blood pressure was 130/80. I was very surprised but he felt it could be due to the travel or vertigo or voice issues. I also know that bereavement can have major physiological impacts and increased blood pressure is one of them (I was in Hawaii for my darling mom’s memorial).

I finally made the connection when my blood pressure measured 137/84 a few days later and stopped drinking the tea immediately. Over the next few days it came down to 127/93 and then 121/90 and then 118/84. I expect it to continue to come back down to my normal low blood pressure and will update this blog when it does.

As far as symptoms, I was just not feeling myself and had a strange feeling of apprehension, spaciness and breathlessness when talking too much. These are much improved having stopped the tea. My naturopath also recommended eating a banana each day to increase my potassium levels and to have epsom salt baths to help regulate the electrolytes in my body.

I will admit there are the above confounding/contributing factors – grief, voice loss, travel, vertigo, insecticide exposure – so I can’t be sure it’s only the licorice in the tea, and I’m not willing to test it out right now.

(Update Oct 13, 2023: A week later and it’s now pretty much back to my usual low blood pressure. Over the course of this last week it measured 125/82, 118/91, 127/84, 118/85 and today it’s 112/85. I will continue to track.)

How much licorice tea is too much?

The authors of the above case report mention this about the dose of glycyrrhizin:

Experimental studies have shown that the rise in blood pressure caused by liquorice follows a linear dose–response relationship. Doses of as little as 75 mg of glycyrrhizin (equivalent to 50 g of standard liquorice confectionery) given daily for a 2-week period have been shown to cause a significant increase in systolic blood pressure (the first number).
In a survey of 33 brands of liquorice tea, the mean glycyrrhizin content was found to be 126 mg/L (range 2–450 mg/L). A cup of liquorice tea with a volume of 250 mL could therefore be expected to contain, on average, approximately 31.5 mg of glycyrrhizin.”
The European Scientific Committee on Food advises that regular glycyrrhizin doses of 100 mg/day present a risk to health, and advocate a safe average daily intake of no more than 10 mg/person/day. This is an amount equivalent to less than half a cup of liquorice tea or just 6 g of liquorice confectionery daily.

In the above published case, the patient had been “averaging around 4–6 cups per day, and had been consuming the licorice tea for about a year.” She was “unwittingly consuming daily volumes of liquorice tea containing up to 190 mg of glycyrrhizin, well in excess of the recommended limit” of 10 mg per day. It was 8 months before she started to notice the adverse effects, but I do wonder how long she had high blood pressure.

We have a home blood pressure monitor but I haven’t used it for ages and if I hadn’t gone in to the doctor for my vertigo, my elevated blood pressure may have gone unnoticed for a while too.

How much did I consume: a total of 10 Yogi Throat Comfort tea bags over the course of a week. The day before leaving I had a few cups of hot tea and was thrilled to be able to talk on my last day there. I then drank it all day on the 15+ hour flight back: I had 2 tea bags in my 2 liter / 2 quart water bottle and filled it up a few times with cold water. And I continued to do this once I was home, having it next to my bed if I woke up coughing in the night. I was probably getting 3 or 4 times more than the safe average daily intake of 10 mg/person/day.

I love licorice tea and drink it from time to time, maybe 2-4 cups a month. I’m quite surprised it affected me so quickly but have never consumed this amount and in such a concentrated time period.

Will I drink Yogi Throat Comfort tea or other herbal teas that contain licorice?

For now, I think I will – the Throat Comfort tea helped so much with my voice – but when I do I will monitor my blood pressure carefully and then make a final decision.

I also plan to dig a bit further into some of the confounding factors I mention above to see how they could possibly have made me more susceptible.

I do also have dietary oxalate issues so this could play into the effects of glycyrrhizin on the kidney. I’m finding mixed results on the oxalate content of licorice: some papers say high and some say low. But I didn’t have any of my typical oxalate reactions such as painful feet or eyes. I have, however, noticed some stiffness in my left hip the last few days so will be looking further into this aspect.

(Update Oct 13, 2023: Licorice tea is listed as low oxalate on the Trying Low Oxalates Facebook group but they will be updating their spreadsheet based on a paper I just shared with them – Oxalate in Foods: Extraction Conditions, Analytical Methods, Occurrence, and Health Implications “Licorice was the highest-oxalate food reported in this review with 3569.3 mg total oxalate/100 g FW (fresh weight).” (this is higher than spinach, sweet potatoes and rhubarb which are really high oxalate)

My takeaway messages – a warning and listen to your body

There is no licorice hypertension warning on this Yogi Throat Comfort tea box (or my Tulsi Licorice tea) and I do feel there should be 2 warnings: the usual warning about licorice if you have high blood pressure AND a general warning that licorice may also affect you if you have low or normal blood pressure.

My other takeaway message is this: listen to your body and get checked out when things don’t seem as they should be.

Has something like this happened to you? How much licorice tea did you consume, which brand and over what period?

Do you typically have low blood pressure and were you also caught by surprise?

Did you know about the caution to avoid licorice if you have high blood pressure?

And what about the fact that licorice may also affect you if you have low or normal blood pressure?

5-HTP for a calm brain, and a racing mind at night: questions and answers

April 16, 2021 By Trudy Scott 39 Comments

5-HTP is an amino acid, made from the seeds of an African plant, Griffonia simplicifolia, and used as a supplement to ease low serotonin symptoms. With low levels of serotonin you’ll experience the worry-type of anxiety with ruminations, obsessing, panic attacks, insomnia (often lying awake worrying). This type of anxiety is different from the low GABA physical/tension type anxiety. Other low serotonin symptoms include low mood/depression, late afternoon and evening carbohydrate cravings, pain, digestive/IBS symptoms, PMS, irritability, rage and anger, TMJ, low confidence, imposter syndrome and perfectionism.

When I share my low serotonin blogs on Facebook I receive so many great questions about 5-HTP. Today I’m going to share some of these questions and my answers so you can get the benefits too.

Gail asks why 5-HTP stopped working for her when it had been working so amazingly well:

I took 5-HTP and it worked amazingly….for about 6 months. Then it did nothing. Any idea why?

I took 100 mg per day. It’s hard to explain, but it calmed my brain down. I wasn’t so quick to blurt things out during the day and at night I was able to sleep because my mind wasn’t racing. Nothing else changed at that time. That was a few years ago, I think I’ll buy more and try again

I would guess that something did shift around the 6 month mark and would try and identify what it was so you know for the future. It could have been accidental gluten exposure (from the diet or even cosmetics), hormonal shifts (perimenopause or menopause), adding collagen or gelatin on a regular basis (this can lower serotonin in susceptible folks) and/or changes in thyroid health.

If you have pyroluria and were exposed to major stresses (life stresses or toxic mold etc.) you’d lose vitamin B6 and this could affect serotonin production. The addition of the birth control pill and antidepressants can also deplete vitamin B6. I share some possible reasons for low serotonin on this blog on imposter syndrome (as mentioned above, imposter syndrome is a common sign of low serotonin).

With these wonderful benefits Gail experienced, trialing 5-HTP again is worth considering. Because 5-HTP works so quickly she’ll feel that sense of calm right away and she won’t blurt things out during the day (possibly caused by lack of confidence and/or irritability and/or anger?). Also, her mind won’t race at night, she’ll fall asleep quickly and will stay asleep, waking rested, calm, happy, confident and optimistic.

And in future if something like this happens again, I’d try to identify the cause and bump up 5-HTP temporarily.

Wendy asks about headaches as an adverse effect:

What do you recommend if 5-HTP gives you headaches?

Headaches are not a common adverse effect with 5-HTP (compared to the amino acid tyrosine which is recognized to cause headaches and migraines in susceptible folks).

Even if you are seeing benefits – for the worry-type anxiety and other low serotonin symptoms – with 5-HTP you don’t ever want to push through with something like headaches and continue to take it. I have clients use less 5-HTP and observe if they still see the benefits with no headaches.

We also make sure low serotonin is the issue. If it’s not then any amount of 5-HTP will either do nothing or cause adverse effects. If the issue is low serotonin then I have clients do a trial of tryptophan.

If the 5-HTP is being used to ease low mood/depression caused by low catecholamine or low endorphins depression then neither 5-HTP or tryptophan is going to help and may cause adverse effects. And tyrosine and/or DPA are better choices.

Gerry asks this question after my interview on Your Best Sleep Ever Summit:

Great talk Trudy. When you want to increase serotonin, do you take both 5-HTP & tryptophan or just one or the other?

They can be used alone or both can be used together. I like to have clients add one new amino acid supplement at a time so we know what is working before confounding things with another one. I typically start with tryptophan for low serotonin support simply because I have such good results with it and because 5-HTP can raise cortisol in some folks.

We start with tryptophan mid-afternoon and evening (after doing a trial earlier in the day to make sure it helps). If tryptophan causes adverse effects or doesn’t work then we do a trial of 5-HTP and then use it afternoon and evening (when serotonin levels tend to drop).

If tryptophan is working in the afternoon and evening, and additional support for worry or ruminations or panic or anxiety is needed earlier in the day, we may consider 5-HTP which can often also help improve focus. We may also consider tryptophan earlier in the day too.

It’s very individualized and we may mix and match to find the ideal combination and dosing based on trials and symptom resolution. It’s important to be aware that some folks do better on 5-HTP and some do better on tryptophan.

Here are some useful blogs related to low serotonin and the amino acids:

You can see the 5-HTP and tryptophan products I use with my clients here on the supplements blog.

As always, it’s not only the low serotonin we need to address. 5-HTP offers quick relief but we must always do a full functional workup looking at diet, nutritional deficiencies, digestion, all hormones, toxins and infections (and so on) so we can address all possible root causes – and why serotonin is low in the first place.

Thanks to these folks for asking good questions and for allowing me to share here.

What questions do you have about 5-HTP?

Which low serotonin symptoms can you relate to and has 5-HTP or tryptophan helped? Or have you found success with a combination.

Tryptophan ends TMJ pain, headaches and worry, and improves mood and sleep: a success story

July 17, 2020 By Trudy Scott 32 Comments

Today I’m sharing a success story on how the amino acid tryptophan, taken as a supplement, ends TMJ (temporomandibular joint) pain and headaches in a woman in my community. She had the added benefits of an improved mood and less worrying and her sleep improved too.

There is evidence to support the low serotonin connection to TMJ and pain like fibromyalgia and I share that research below.

Before I share the success story, in case you’re new to neurotransmitter imbalances, the other symptoms we see with low serotonin are the worrying-type of anxiety, panic attacks and phobias, lack of confidence, depression, negativity, imposter syndrome, PMS, irritability, anger issues, insomnia and afternoon/evening cravings. Tryptophan can be used to boost serotonin levels and improve these symptoms as you’ll see below.

Right after speaking on the recent Trauma and Mind-Body Super Conference, Renee shared her wonderful success story on Facebook:

Out of all the interviews I felt yours gave the most actionable steps. I was taking amitriptyline for TMJ and didn’t like the side effects, however what other options did I have? Not many according to my GP [general practitioner]. Luckily I found your suggestion of tryptophan. And I can’t explain how much of a change it made! I weaned off the medicine and took tryptophan instead and not only did it help the TMJ but also helped me feel more even emotionally.

I am being referred for trauma therapy and I am optimistic that I will be discomfort free soon.

So huge thanks for sharing your knowledge. It helped me at a time when I was really starting to think there were no ‘natural’ options and conventional meds were all I could take.

I checked in with her, thanking her and acknowledging her wonderful feedback. I also asked how much tryptophan made this difference and how quickly she saw an improvement. And what side-effects she was seeing with the medication. She shared this:

I am a week into taking tryptophan, and I’m taking 500mg. I saw improvements with the TMJ within an hour of taking it. My jaw felt loose and I had no headaches, I also felt more ‘even’ mood wise. Like an underlying worry had gone. [worry is a classic symptom of low serotonin – more on that here]

I also had some stress yesterday that usually would have made me crumble, but instead I was able to stand up for myself and see subjectively the extent of the issue and resolve it. I am amazed!

My original medication (amitriptyline) had given me extreme dry mouth, which I found hard to manage, the headaches were also not relieved as much as I had hoped, plus I was having sessions of palpitations.

I haven’t had any palpitations from the day I started tryptophan whereas the dry mouth took some time to subside.

These really are wonderful results and typical that we’d see results this quickly with tryptophan if the root cause of the TMJ and headaches is low serotonin. It can sometimes take a few weeks to find the ideal dose but Renee found it with the initial trial amount of 500mg.

Sleep improved but made her too sleepy too early (some of the medication side-effects went away too)

The tryptophan also improved her sleep (and the palpitations and dry mouth side-effects from the medication stopped):

I was struggling to get to sleep and stay asleep, suffering bouts of insomnia, prior to any medication. I still am sleeping well taking tryptophan which I am pleased about.

She did however share that the timing of the tryptophan was making her too sleepy too early in the evening and she was planning to shift the timing:

I am finding tryptophan is making me feel drowsy in the evening, so I am trying different times during the day to take it. Hopefully I can push back the tiredness to perhaps 8/9 at night to coincide with bedtime.

My advice to her was that I have my clients use tryptophan MA (mid-afternoon) and evening and if MA makes them too sleepy they just do an evening dose. That can be enough for TMJ the next day. Sometimes more than 1 x 500mg in the evening is needed for easing TMJ and headache pain that night and the next day too.

I did check with her about weaning off the medication as cold-turkey quitting of psychiatric medications are dangerous and not advised. She shared this:

I weaned off over 1 week, but I was only on it for 8 weeks in total before I found tryptophan.

A slow taper under the guidance of the prescribing doctor is always recommended (more on this for amitriptyline/Elavil withdrawal here).

Some research supporting this serotonin/TMJ connection

Plasma tryptophan and kynurenine in females with temporomandibular disorders and fibromyalgia – An exploratory pilot study

…both temporomandibular disorders myalgia (TMDM) and fibromyalgia (FM) have been linked to central and peripheral changes in serotonin availability.” (tryptophan is not used in this study which also makes the serotonin/anxiety connection)

The effects of dietary tryptophan on chronic maxillofacial pain and experimental pain tolerance

Over the 4 weeks of the study, there was a greater reduction in reported clinical pain and a greater increase in pain tolerance threshold in the tryptophan group than in the placebo group. The tryptophan group was given “three grams of tryptophan in conjunction with a high carbohydrate, low fat, low protein diet.”

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

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

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

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

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

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

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

Wrapping up and your feedback

I appreciate Renee sharing her success story and I’m thrilled with her results.

Please share your TMJ/headache tryptophan success story if you have one (and how much tryptophan or 5-HTP helped you).

What about mood, anxiety and sleep (and any other low serotonin symptoms) – did they improve too?

And do share if other nutrients or approaches have helped.

And feel free to post your questions here too.
