Tryptophan

Increasing tryptophan or 5-HTP temporarily when a winter dip in serotonin causes more severe anxiety, OCD and/or the winter blues

December 24, 2021 By Trudy Scott 30 Comments

Don’t forget that serotonin takes a dip in winter when the days are shorter and there is less light. If you’re currently using tryptophan or 5-HTP to boost low serotonin and ease low serotonin symptoms – worry-type anxiety, panic attacks, insomnia, ruminations, PMS, irritability, negativity, perfectionism, obsessiveness, lack of confidence, anger/rage, afternoon/evening cravings – you may find you need to increase your dose for a few months.

This will especially be the case if you check off winter blues or more severe winter anxiety (yes it’s a thing and published in the research) on the low serotonin symptoms list.

I shared this on Facebook last week and the feedback ranged from surprised to curious to confirmatory.

In this blog I’m sharing some of the feedback and some of the supporting evidence, as well as other factors to consider.

The addition of 5-HTP in the morning and a light box

Kathy thanked me for the reminder and shared the changes she makes in the winter months:

Thanks for the reminder! I need to increase my dose this time of year… I can feel myself feeling “down”. I take 500 mg Tryptophan before bed and 100 mg 5-HTP in the morning before breakfast. I also use a light box in the morning while eating breakfast, which helps.

This is an increase from her typical dosing in the spring and summer when she only takes tryptophan at night before bed.

She also only uses her light box or SAD (seasonal affective disorder) lamp in winter. You can read more about SAD/full spectrum lamps here. They are also a wonderful way to boost serotonin and mood in the winter.

My daughter’s anxiety and OCD goes through the roof

Mark shared about his daughter’s anxiety and OCD (obsessive compulsive disorder):

Every year from October – March, my daughter’s anxiety and OCD goes through the roof. At first we thought it was the transition from summer to school, then the craziness of the winter holidays and suspected mold allergy. Now, based on this information, a winter/less light induced dip in serotonin may be an additional factor we hadn’t considered. We’ll try adjusting her 5-HTP dose and see if we gain some improvement. Thanks for the tip.

It’s really common for families to attribute the more severe anxiety and OCD to the stress and craziness of the winter holidays. And of course suspected mold issues do need to be looked into and addressed. But even then, the dip in serotonin can compound all these factors.

Planned tryptophan bump for Christmas sugar cravings and holiday family stress

Carol shared this about her plans to temporarily boost serotonin:

I am one of those light weights that was able to do one 500 mg pill a day of tryptophan. But I do think that it would help to bump it up to two a day to get me through the Christmas sugar cravings AND holiday family stressful get togethers! I’m all about taking the minimum effective dose but this is helpful to know that there could be a temporary boost just to get you through this time!

It’s wonderful that 500mg tryptophan is enough for her and I’m all for a minimum effective dose! However the winter dip in serotonin – and increased sugar cravings and family stress – is a common reason many folks bump up the dose for a month or more.

You may also find you made the change intuitively. Linda shared this: “I had made the adjustment. I just did not realize the reason why.”

A question about timing of 5-HTP and what to do in Spring

Suzanne shared that she uses a SAD light (also called a light box) and finds that it helps. She asks:

Can I just take the 5-HTP on days with no sun or is it better to have it build up in my system? When spring rolls around, do I taper off or can I just stop taking it?

This is my feedback: I haven’t had anyone just use 5-HTP on cloudy days but it’s worth a trial. If you are noticing increased anxiety and mood changes only on cloudy days and using the SAD lamp on those days helps, then using 5-HTP on those days may be enough. If not, use 5-HTP consistently/daily through the winter months.

Amino acids do not need to be tapered but I find my clients do better when they are reduced over a few weeks. Some folks also choose to just stop taking them and do fine.

I appreciate all the feedback and the great questions. I’ll report back when I hear how Mark’s daughter does with the adjusted 5-HTP and how Carol does with the bump in tryptophan (and any other feedback I get from these folks).

Some of the research and possible mechanisms

There are many studies that support serotonin changes and seasonal variations in mood. Here are just two of them:

Effect of sunlight and season on serotonin turnover in the brain “Alterations in monoaminergic neurotransmission in the brain are thought to underlie seasonal variations in mood, behaviour, and affective disorders… turnover of serotonin by the brain was lowest in winter. Moreover, the rate of production of serotonin by the brain was directly related to the prevailing duration of bright sunlight… Our findings are further evidence for the notion that changes in release of serotonin by the brain underlie mood seasonality and seasonal affective disorder.”
Sunshine, Serotonin, and Skin: A Partial Explanation for Seasonal Patterns in Psychopathology? “one contributory facet may be the role of sunshine on human skin. Human skin has an inherent serotonergic system that appears capable of generating serotonin.”

Other factors to consider: low vitamin D, sugar, pyroluria and phenols

There are other low-serotonin related factors to consider too:

Low vitamin D is common in the winter and sufficient levels are needed for making serotonin. This paper, Vitamin D and the omega-3 fatty acids control serotonin synthesis and action, part 2: relevance for ADHD, bipolar disorder, schizophrenia, and impulsive behavior describes how“Brain serotonin is synthesized from tryptophan by tryptophan hydroxylase 2, which is transcriptionally activated by vitamin D hormone. Inadequate levels of vitamin D (∼70% of the population) and omega-3 fatty acids are common, suggesting that brain serotonin synthesis is not optimal.”
The increased consumption of sugar at this time can lead to reduced zinc, magnesium and B vitamins (like vitamin B6 and thiamine) and this can further reduce serotonin levels, which relies on these nutrients as cofactors for production. By boosting serotonin with additional tryptophan or 5-HTP you can actually reduce some of the cravings.
If you have the social anxiety condition called pyroluria, the added stress of family and holiday gatherings can also contribute to zinc and vitamin B6 being dumped, and further impacting serotonin production.
Christmas tree phenols can be a trigger for anger, meltdowns, anxiety, hyperactivity, insomnia, aggression, self-injury and autistic symptoms in susceptible individuals

Resources if you are new to using tryptophan and 5-HTP as supplements

If you are new to using the amino acids as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see the low serotonin symptoms here) and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

If you suspect low serotonin 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 so you are knowledgeable. And be sure to share it with the team you or your loved one is working with.

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 acid products 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.

Another option is the budget-friendly GABA QuickStart Homestudy program.

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.

Wrapping up and your feedback

Have you noticed this winter dip in serotonin and made adjustments to your 5-HTP or tryptophan? And do you feel less anxious, less obsessive, not as low and with fewer sugar cravings?

Do you find that using a SAD lamp/full spectrum light at this time helps even further?

Were you aware that serotonin dipped in winter and could be playing a role for you? Or did you think it was just the stress and overwhelm of the holidays (and /or some of the emotional upheaval some of us face at this time)?

If you’re a practitioner, have you seen this with clients or patients?

Have you also noticed you need to adjust your GABA and other amino acids at this time too (both GABA and dopamine show seasonality)?

Feel free to ask your questions here too.

Tryptophan doesn’t work, then it does and then it doesn’t: could it be hormonal shifts, dietary factors and/or parasites?

November 26, 2021 By Trudy Scott 19 Comments

Have you been in a situation where tryptophan doesn’t work, then it does work, and then sometimes it doesn’t work as expected? There is a reasonable explanation as to why it may not work initially – too much or too little was used. The variable results and the need to switch between lower and higher doses on an ongoing basis can happen but it’s not very pronounced unless there is a specific reason. In this blog I cover some of these reasons – hormone shifts, dietary factors and parasites/other digestive issues.

I’m writing this blog in response to a question that was posted on one of my speaker pages on the Anxiety Summit: Gut-Brain Axis. This is the actual question:

I tried to use tryptophan the first time (whole capsule) and got really high. Some time later I tried again, but used 1/4 of a capsule and had a good result. A few weeks later 1/4 of the capsule didn’t work at night. So I went up to half a capsule. And that’s where I am now. But some nights (very rare) I can only get good results from a whole capsule. I use it along with the same amount of GABA. Is that a normal reaction for tryptophan?

I don’t know what brand of tryptophan she was using but assume 500mg was her starting dose and she now shifts between 125 mg (¼ capsule) and 250 mg (½ capsule) with variable results.

It’s not unusual for someone to not feel great on 500 mg if that dose is too much for their unique needs. She did the right thing by lowering her dose. It’s also reasonable that someone may find 500 mg as an initial dose isn’t enough to reduce symptoms.

The variable results and the need to switch between 125 mg and 250 mg can happen but it’s not very pronounced unless there is a specific reason. Some of these reasons include hormone shifts, dietary factors, parasites/other digestive issues, thyroid issues, low lithium, product quality and environmental factors. More on all this below.

Hormone shifts/more serotonin is needed in the luteal phase

I have my clients track when the variability happens, with female clients documenting their cycles. Some women need more serotonin support in the luteal phase i.e. after ovulation and right up to before their periods. Some may even need additional tryptophan for the first few days of their periods too.

Write about tryptophan working well in the luteal phase in this blog – Tryptophan for PMS: premenstrual dysphoria, mood swings, tension, and irritability

In a study published in 1999, A placebo-controlled clinical trial of L-tryptophan in premenstrual dysphoria, tryptophan was found to reduce symptoms of PMS when used in the luteal phase or second half of the cycle (i.e. after ovulation):

37 patients with premenstrual dysphoric disorder were treated with L-tryptophan 6 g per day, and 34 were given placebo. The treatments were administered under double-blind conditions for 17 days, from the time of ovulation to the third day of menstruation, during three consecutive menstrual cycles.

They looked at dysphoria, which is defined as a state of unease or generalized dissatisfaction with life, plus mood swings, tension (and anxiety), and irritability and they found a 34.5% reduction of symptoms with tryptophan compared to 10.4% with placebo.

The paper concludes: “that these results suggest that increasing serotonin synthesis during the late luteal phase of the menstrual cycle has a beneficial effect in patients with premenstrual dysphoric disorder.”

It’s a small study but the results are powerful and it’s something I see clinically with my clients. The one big difference is that I typically have clients using tryptophan throughout the month.

But if you are seeing tryptophan work and then not work at similar times each month this is something to consider and track. And then if need be, increase and decrease tryptophan accordingly (and track again).

Dietary factors – collagen, gluten, sugar, wine and coffee

There are other factors to consider too and dietary impacts is one. For example, collagen leads to a higher need for tryptophan in susceptible individuals (due to it’s serotonin-lowering effects – I blog about this here)

Another dietary factor is accidental gluten exposure in susceptible individuals or a newly discovered gluten issue

High sugar intake, alcohol and/or caffeine consumption may also be a factor – contributing to added stress for the adrenals and depletions in zinc and the B vitamins. This can contribute to lowered serotonin and a need for a higher dose of tryptophan.

Now imagine if it’s just before her period and she adds collagen to her diet and she also eats out and gets zapped by gluten. Triple whammy for this woman!

And she goes to a party and happens to indulge in cocktails or wine, and then goes on a binge at the dessert table, followed by a few cups of coffee (or even one dessert and one cup of coffee).

A food-mood log really helps you figure things out. And then, if need be, increase and decrease tryptophan accordingly. And track again and address the dietary issues.

Parasites and other gut issues

If she has a very pronounced shift in symptoms for 4-5 days around a full moon each month – more severe insomnia, more anxious, more depressed – I would want to check for parasites.

I would also want to check for other digestion issues like dysbiosis, SIBO (small intestinal bacterial overgrowth), candida and liver health as they may all be factors. With SIBO and candida, dietary slip-ups may make symptoms worse right after the slip-up, for example increased bloating making sleep and anxiety worse.

Using tryptophan sublingually/opened on the tongue may bypass some of the digestive/liver issues until they are resolved.

As mentioned above, if need be, increase and decrease tryptophan accordingly. And track again and address the underlying issues.

Other factors to rule out – thyroid, lithium, environmental factors and the product

Two other underlying root causes we always want to rule out when we see variable results using tryptophan (and any of the amino acids) are Hashimoto’s thyroiditis (because we can have variable thyroid results – sometimes hypo/low and sometimes hyper/high) and low levels of lithium (because this can affect the results we see with all the amino acids).

And we always check environmental factors like mold, EMFs and outside stresses. And look for infections like Lyme disease or EBV. If the basics are not unearthing the solution we continue to dig deeper and do a full functional medicine workup. And adjust the tryptophan as needed.

And finally the quality of the product is key. I find Lidtke Tryptophan to be better than many other brands. I’ve also had many clients switch to Lidtke tryptophan and see better results and often need a lower dose.

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

If you are new to using the amino acids tryptophan/5-HTP and the other amino acids as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see the low serotonin symptoms here) and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

I always appreciate good questions like this and hope this feedback has helped her and you too if you’ve experienced something like this (or if you do in the future). In case you’re wondering, this question was posted after someone tuned into my interview, “GABA & Tryptophan: Gut-Anxiety Connections” on the Anxiety Summit 5: Gut-Brain Axis.

Have you had a variable response to tryptophan (or 5-HTP) and can you relate to any of this?

What did you figure out to be the reason?

Teen with anxiety, low self-esteem and insomnia: how to do a one-off trial of tryptophan to figure out if she has low serotonin

August 20, 2021 By Trudy Scott 23 Comments

A mom asks for advice for her teenage daughter who has anxiety, low self-esteem issues, insomnia, experiences negativity and has phobias. She wants to know if serotonin support may help and where to start. I share my feedback confirming that these are low serotonin symptoms and that I would do a trial of tryptophan. I go deeper in this blog and also go into detail about how I would do a one-off trial (or evaluation) of tryptophan if I was working with this family. I also share why I’d look into low GABA, seasonal allergies and the birth control pill. And I discuss the importance of being proactive given the increasing suicide and self-harm in this age-group, with the pandemic compounding the increase.

Here is the question that Maria asked about her daughter:

My 13-year-old teen has always suffered from insomnia, sometimes light, sometimes a bit heavier, depending on the period. She has suffered from asthma from a young age, even if this issue has improved enormously, it is sometimes present, specially during spring time as she is allergic to different plants. She would suffer from sugar cravings in the past as we were trying to change her diet. Things are going better in this respect as well; however, negativity, phobias, low self esteem and anxiety are always present for her.

Are these signs of low serotonin? How could we help her feel better? Should serotonin pills be applied directly? Would this make the system dependent on it? If amino acids should be supplemented, how should we do this, considering her age?

I responded that yes, negativity, phobias, low self esteem and anxiety (the worry type) are signs of low serotonin. Insomnia can also be caused by low serotonin especially if her daughter is lying awake, overthinking and worrying about things.

I shared that the body does not get dependent on the amino acids and I’d consider a trial of tryptophan to address her symptoms.

Doing a one-off trial/evaluation of tryptophan based on her symptoms

If I was working with this family, I would help this mom figure out for sure if her daughter has low serotonin by reviewing the low serotonin symptom list with her, and helping her rate them on a scale of 1-10 with 10 being the worst.

This can often be challenging for a 13-year old: giving the symptoms a severity rating and being able to identify exactly how she feels. Her ratings may also be reflective of where she is in her cycle at the time and may fluctuate more in the month if her cycle is not yet regular. Working together with mom we can hopefully figure this out. If not, we do the best we can with the information we have.

The next step is picking one or two symptoms that are easy to measure the day we do the initial trial or evaluation. For this young girl I’d pick anxiety/worry and negativity and ask her some questions that would help us assess before and after results of the one-off trial /evaluation of tryptophan:

For anxiety and worry she may say it’s also a 9 and give me this example: “I’m really worried about performing in the concert – I keep thinking about it all day long and at night.”
For negativity she may say it’s a 9 and give me this example: “I really don’t think I’m good enough to be in the dance class.”

Both tryptophan and 5-HTP can raise serotonin but I like to start with tryptophan. I typically start with 100mg Lidtke chewable tryptophan in children/teens so I’d have her chew one tablet and then check back in the next 2 to 5 minutes (or maybe a little longer for some folks).

This is the kind of feedback I’m looking for:

With regards to anxiety and worry she may say: “Gosh, I completely stopped thinking about the concert. I’m not worrying about it at all. Now that you ask I’m thinking about it again but I think my worry/anxiety is about a 5 now.”
With regards to negativity she may say: “I think I feel better about being in the dance class. I think I can do it. My negativity feels like it’s a 5 or 6”

Since this teen responded so well, I’d have her start taking tryptophan midafternoon and evening (away from protein) and we’d increase if needed, each week, and based on her symptoms.

I have everyone keep a food mood and supplements log and mom could help her do this too.

GABA, seasonal allergies and the birth control pill

I also always assess low GABA when someone is anxious (especially if she also has physical anxiety, tension, stiff muscles) and has insomnia. We’d do the same one-off trial with a product like GABA Calm (or similar) once we’ve established a good dose of tryptophan for easing her symptoms.

This mom also mentioned Spring time allergies so I also shared this blog with her: 5-HTP and/or tryptophan to help with increased anxiety, panic attacks and depression caused by spring allergies. Depending on the season, her daughter may score higher on some of the low serotonin symptoms.

I’d also want to know if her daughter is on a birth control pill (often prescribed at this age for acne) because it can contribute to anxiety and depression.

Being proactive is wise given the rise in suicide and self-harm in this age group

Being proactive about addressing low serotonin symptoms quickly is wise given the rise in suicide and self-harm in this age group. This 2021 Italian study discusses the role of emotional dysregulation when it comes to and self-injurious thoughts and behaviours in high-school students:

Overall, 11.1% of adolescents reported self-harming behaviours without suicide ideation or attempts, 6.4% declared having thought to suicide without acting a suicide attempt or self-harm, 1.4% declared having attempted suicide and really thought to take away their life.

Unfortunately, the pandemic has also made things worse for many adolescents. This study reports that Canadian adolescents appear to be experiencing “higher rates of self-harm thoughts and behaviours relative to before the pandemic.”

It’s important to keep in mind that pre-teens and teens may not be willing to admit that they are engaging in self-harm like cutting or burning, or thinking about taking their lives.

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

If you are new to using the amino acids tryptophan/5-HTP or GABA as supplements and want to know more in case you need them in a future situation, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the low serotonin and low GABA symptoms here) and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

It also covers all the basics of a healthy diet. It’s a comprehensive approach – amino acids AND diet. I’d also want to know what her diet is like right now – gluten-free, sugar-free, caffeine-free, eating protein at breakfast for blood sugar control, real whole foods, grass-fed red meat, wild fish, fermented foods etc?

Thanks to this mom for asking the question and allowing me to use it as a teaching tool for my community. Let’s get her daughter and all teens feeling their best again.

Can you relate to the question this mom asked? Does it sound similar to what your daughter is experiencing right now or a client/patient?

Do you do a one-off trial /evaluation like this to find out if serotonin support is needed? Or have you done this in the past with your daughter, family member or yourself?

What are the before and after questions (and symptom ratings) and did tryptophan help?

Feel free to post any questions here too.

Timing/combinations of tryptophan and 5-HTP for anxiety, depression and bad sleep (premenstrual dysphoric disorder/PMDD)

August 6, 2021 By Trudy Scott 28 Comments

Naomi asked these questions about tryptophan timing, using it in the morning and her PMDD (premenstrual dysphoric disorder) symptoms of anxiety, depression and bad sleep:

I heard your talk on the Biology of Trauma summit, thank you it was great. When’s the best time to take tryptophan? I want to try it for PMDD depression & anxiety along with accompanied bad/little sleep.

I’ve read it needs to be taken on an empty stomach. If I take it in the mornings will it make me drowsy for the day? I struggle with having an empty stomach in the evenings as I often need to eat something close to bedtime to have the energy to sleep through.

I thanked Naomi for her kind words and shared that tryptophan is best used mid-afternoon and evening when serotonin levels take a downwards dip. And tryptophan (and the other amino acids) must always be taken on an empty stomach/away from protein. I also shared how she may want to experiment with also using 5-HTP at various times in the day and in different combinations (more on that below).

Regarding the evening dose, tryptophan can be used between dinner and a bedtime snack if a snack is necessary for blood sugar stability (for improving sleep).

I shared this blog as an additional resource for her – Tryptophan for PMS: premenstrual dysphoria, mood swings, tension, and irritability

In a study published in 1999, A placebo-controlled clinical trial of L-tryptophan in premenstrual dysphoria, tryptophan was found to reduce symptoms of PMS when used in the luteal phase or second half of the cycle (i.e. after ovulation).

I’ve seen both tryptophan and 5-HTP improve symptoms in 2-3 cycles (often in conjunction with GABA) and other steps I outline in the above blog. I don’t typically have clients only use it after ovulation but this is one way a trial could be approached.

Using a combination of tryptophan and 5-HTP

Regarding Naomi’s question about taking tryptophan in the morning and her concern about it making her drowsy during the day, this is my feedback about possibly experimenting with also using 5-HTP at various times in the day and in different combinations:

Many folks do not need serotonin support earlier in the day since it goes down at the end of the day but there are some women who do
If you are someone who does need serotonin support earlier in the day, you may do very well with tryptophan i.e. it may not make you sleepy
If you are someone who does need serotonin support earlier in the day, you may find that tryptophan does make you sleepy and you do better with 5-HTP earlier in the day. In this case, you would use 5-HTP in the morning (as needed, possibly on waking and/or mid-morning) and tryptophan in the afternoon and evening.

And just to add to the mix of variations, keep in mind that some folks do better on 5-HTP (at any time of the day) and some folks with high cortisol find 5-HTP too stimulating.

The way to figure out which amino acid and which combination works best for you is to do a trial of the various combinations and keep a careful log of your responses.

I really do recommend my book when you are new to the amino acids

I also reminded her that when you are new to the amino acids I really do recommend my book “The Antianxiety Food Solution” so you understand exactly how to use them. There is an entire chapter on the amino acids.

I also cover other anxiety nutrition solutions like gluten/sugar/caffeine removal (all important for anxiety, depression and sleep), blood sugar control (often a factor in not being able to sleep through the night and daytime anxiety), gut health (affects mood and can also affect sleep), pyroluria (the zinc, vitamin B6 and evening primrose oil are key for hormone health). I reminded her that it’s the amino acids and diet we must work on.

If you’ve been reading my blog posts and following me for awhile, you know I speak on many summits. I see these interviews as a great introduction for folks new to the amino acids but cannot possibly cover everything in 45-60 minutes.

Additional information on PMDD and low serotonin

Here is additional information on PMDD and low serotonin – Premenstrual Dysphoric Disorder: Epidemiology and Treatment:

It is possible that women with PMDD are more sensitive to [the] effects of estrogens on serotonergic function. Women with PMDD or PMS exhibit specific serotonin abnormalities that are particularly apparent in the late luteal phase [or second half of the cycle] when estrogen levels have declined. These include a deficiency in whole blood serotonin, blunted serotonin production in response to l-tryptophan challenge and, and aggravated premenstrual symptoms during tryptophan depletion.

Be aware that the authors recommend antidepressants as the first-line treatment for PMDD and unfortunately do not mention using tryptophan, GABA or a dietary approach.

I always use this approach when serotonin is low

Keep in mind that this discussion about tryptophan and 5-HTP timing and combinations is not necessarily only applicable for PMDD or PMS but can be used across the board when serotonin support is needed. I always use this approach when serotonin is low i.e. someone has worry-type ruminating anxiety, depression, afternoon and evening cravings, irritability, anger issues.

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

If you are new to using the amino acids tryptophan/5-HTP or GABA as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see all the low serotonin symptoms here) and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

As I mentioned above, if you suspect low serotonin 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 so you are knowledgeable. And be sure to share it with the team you or your loved one is working with.

Have you (or a loved one) been diagnosed with PMDD, PMS or have low serotonin symptoms?

Has tryptophan or 5-HTP helped and what combination and what timing has worked best for you?

Tryptophan supplementation for anorexia?

July 9, 2021 By Trudy Scott 27 Comments

This blog post highlights the potential importance of tryptophan supplementation in improving therapeutics in anorexia (and other eating disorders) and some of my insights about the 2017 anorexia-tryptophan study. I also share the high incidence of eating disorders, overlaps with anxiety and the case for tryptophan supplementation given the many low serotonin symptoms (anxiety, obsessive thoughts/behaviors, perfectionism, negative-self-talk, low self-esteem and depression) we see with anorexia and other eating disorders. And the importance of a comprehensive nutritional approach.

I’ve updated the original blog with newer research on low zinc and iron with males with eating disorders – and how this ties in with serotonin production and also pyroluria (read on below).

According to The National Eating Disorders Association (NEDA), eating disorders are

serious but treatable mental and physical illnesses that can affect people of all genders, ages, races, religions, ethnicities, sexual orientations, body shapes, and weights. National surveys estimate that 20 million women and 10 million men in America will have an eating disorder at some point in their lives.

While no one knows for sure what causes eating disorders, a growing consensus suggests that it is a range of biological, psychological, and sociocultural factors.

While NEDA does acknowledge that some of the causative factors may be biological, unfortunately there is no mention of nutritional psychiatry or tryptophan on the site. You’ll see this to be the case in the majority of conventional treatment centers.

The 2017 paper on tryptophan potential for anorexia

The paper, Improving therapeutics in anorexia nervosa with tryptophan, does acknowledge that the “growing body of evidence suggests that our diet is an important contributing factor in the development, management and prevention of a number of psychiatric illnesses.”

It discusses what we know about tryptophan being “the sole precursor” of serotonin, a neurotransmitter and that when used as a supplement it has therapeutic benefits when serotonin is low.

The author proposes that excessive dieting and food restriction decrease brain tryptophan and serotonin and propose the “potential importance of tryptophan supplementation in improving therapeutics in anorexia patients” (together with psychotherapy).

Given that anorexia has the “highest lethality of all psychiatric illnesses” and that there are currently “no FDA approved pharmacological treatments available” for anorexia, the urgency for implementing nutritional psychiatry approaches is high. The authors also share that the antidepressants and antipsychotics which are commonly used to treat the co-occurring anxiety, depression, OCD and psychosis are not very effective.

The author mentions a paper that used 250 mg tryptophan twice a day but based on my work with individuals with anxiety, we know an individualized approach is best. A typical starting dose of tryptophan is 500mg used once or twice a day and I use the trial approach to determine the ideal dose for each person.

Incidence of anorexia and eating disorders in general

Here are a few select anorexia and eating disorder statistics from NEDA. I find much of this alarming and in some cases surprising (like the high incidence of males who are affected):

40% to 60% of elementary school girls (ages 6-12) are concerned about their weight
2% to 13% of adolescent girls meet the criteria for eating disorders
Males represent 25% of individuals with anorexia (they are at a higher risk of dying because they are often diagnosed later since many people assume males don’t have eating disorders)
Male athletes, especially those competing in sports that emphasize diet, appearance, size and weight, are at risk. In weight-class sports (wrestling, rowing, horse racing) and aesthetic sports (bodybuilding, gymnastics, swimming, diving) about 33% of male athletes are affected. In female athletes in weight class and aesthetic sports, disordered eating occurs at estimates of up to 62%.
In one study of ultra-Orthodox and Syrian Jewish communities in Brooklyn, 1 out of 19 girls was diagnosed with an eating disorder, which is a rate about 50 percent higher than the general U.S. population.
Despite similar rates of eating disorders among non-Hispanic Whites, Hispanics, African-Americans, and Asians in the United States, people of color are significantly less likely to receive help for their eating issues.
Elevated rates of binge-eating and purging by vomiting or laxative abuse was found for both males and females who identified as gay, lesbian, bisexual, or “mostly heterosexual” in comparison to their heterosexual peers.

Prevalence of anxiety and making the case for low serotonin

The prevalence of anxiety is high in those with eating disorders (which is one of the reasons for this particular blog):

Anxiety is also diagnosed in 48-51% of people with anorexia nervosa, 54-81% of people with bulimia nervosa, and 55-65% of people with binge eating disorder
Two-thirds of people with anorexia also showed signs of an anxiety disorder several years before the start of their eating disorder.

In one study, after dietary treatment (called refeeding), plasma tryptophan levels normalized in patients with anorexia:

Disturbance in serotonin function has been described as central to the psychobiology of this disorder

Plasma TRP normalizes during the course of refeeding, supporting the hypothesis that serotonin function is disturbed in patients with anorexia nervosa.

We also see a large number of low serotonin symptoms in those with eating disorders:

Childhood obsessive-compulsive traits, such as perfectionism, having to follow the rules, and concern about mistakes, were much more common in women who developed eating disorders than women who didn’t.
Binge eating disorder patients … also had significantly higher levels of negative affect, and lower self-esteem
In a study of women with eating disorders, 94% of the participants had a co-occurring mood disorder

[You can find the actual stats and studies quoted above at the NEDA stats link.]

There are all classic low serotonin symptoms: obsessive thoughts/behaviors, perfectionism, negative-self-talk, low self-esteem and depression.

This further supports the rationale for tryptophan supplementation and is another reason for this blog. I have extensive experience in the use of tryptophan and 5-HTP and believe they should be part of all eating disorder programs.

There is one big difference in that typically we see afternoon and evening sugar and carb cravings with low serotonin-type anxiety. Whereas with anorexia, the low self-esteem, obsessive thinking and body dysmorphia (feeling shame or disgust with parts of their body or appearance) may prevent someone acting on these cravings. However, if there are sugar and carb cravings (and bingeing), this is the time they will typically occur.

Here are two recent blog posts that share case studies where tryptophan was used with success:

Anorexia and other eating disorders require a multidisciplinary team and a targeted nutritional approach

I don’t currently work with clients with anorexia as it requires a multidisciplinary team. I did, however, work with a few clients with anorexia when I worked at Recovery Systems over 10 years ago. They had a therapist, nutritionist and doctor on their team and a nutritional approach led to more improvements than they had experienced at prior in-house eating disorder clinics where they had received psychological support only or psychological support and medication. Our approach included addressing low serotonin with tryptophan or 5-HTP, addressing low zinc and low iron, low vitamin D, addressing the gut/microbiome, low B vitamins, low omega-3 fatty acids and more (based on the unique needs of the client).

I now refer eating disorder clients to Dr. James Greenbatt, MD, an eating disorder specialist and integrative psychiatrist. He has a wonderful book on the topic: Answers to Anorexia – a Breakthrough Nutritional Treatment That is Saving Lives, with the second edition coming out soon. In the first edition he does address neurotransmitter deficiencies but we differ in our approach. He doesn’t use individual amino acids like tryptophan or 5-HTP and prefers to use a blend of amino acids based on a blood or urinary amino acid test.

In this article, New Approaches to Treating Anorexia, Dr. Greenblatt covers the multidisciplinary aspect, current treatment options, the limited medical options and the need for targeted nutrition therapy. Although this article doesn’t address tryptophan and low serotonin, he does discuss the key role of zinc, B vitamins and omega-3 fatty acids.

UPDATE: October 10, 2024

Given that most of the eating disorder research is conducted primarily in females, it’s encouraging to share the results of this 2022 paper, Sex differences and associations between zinc deficiency and anemia among hospitalized adolescents and young adults with eating disorders, which reports that “zinc deficiency is equally severe and anemia is more common in hospitalized males with eating disorders compared to females.”

Liquid zinc sulfate tastes like water when zinc levels are low. I saw those with anorexia being willing to drink it when I worked in Julia Ross’ Clinic, so it’s a relatively easy way to start to increase zinc levels and improve appetite. Zinc and iron both help increase serotonin production, and zinc is key for pyroluria/social anxiety which is common in this population.

Also, with pyroluria, morning nausea negatively affects appetite so it’s often helpful to address this in conjunction with using amino acids. Vitamin B6 is part of the pyroluria protocol and is another serotonin co-factor. Evening primrose oil, also part of the pyroluria protocol, improves zinc absorption. This is all covered in the pyroluria chapter in my book.

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

If you are new to using the amino acids tryptophan/5-HTP, GABA or tyrosine as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution (you can see the low serotonin symptoms here) and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

Have you (or a loved one) been diagnosed with anorexia or another eating disorder?

Did you see the most success with an approach that included nutritional psychiatry and serotonin support with tryptophan or 5-HTP?

What if overthinking, fear, anxiety and worry (caused by low serotonin) is holding you back instead of low motivation/low dopamine?

July 2, 2021 By Trudy Scott 50 Comments

One of the first things that comes to mind when someone is stuck and not able to get things done is low motivation caused by low catecholamines/low dopamine. But what if overthinking, fear, anxiety and worry (caused by low serotonin) is holding you back instead? The following case may help you figure it out if any of this applies to you.

William asked this question on one of the tyrosine blogs, justifiably thinking he may need tyrosine to get unstuck:

Excellent article. I may try tyrosine. I have anxiety and shut down when I am about to start something or my mind overthinks and I shut down with worry. I have problems sleeping. I take a group of things…GABA, glycine, 5-HTP but still wake at 3am.

Anyway I always have GOOD intentions of doing things when I wake in the morning….then it goes downhill. I was not always like this but got worse with STRESS from work and now I FIGHT myself to actually do something I used to LOVE to do. Makes me MAD!

I actually am AFRAID just thinking about taking Tyrosine {Not funny}

I FEAR so much it becomes stupid. I think of doing things and SHUT DOWN with worry.

I want my life back…life is too short to suffer knowing HELP is so close. What do you think? Love your articles…

I think this is a great question many others in my community may relate to so I’ve decided to do this as a blog post with his question and a longer response.

I thanked him for his kind words, saying I can’t offer advice via the blog but can share that we need to be careful with tyrosine when someone has sleep issues or anxiety. I also offered some brief thoughts which I’ll elaborate on here so you can understand my thinking as I work with someone.

Is it low motivation caused by low catecholamines/low dopamine?

The first thing that comes to mind when someone is stuck and not able to get things done is low catecholamines and low dopamine. The classic signs are lack of motivation, fatigue, poor focus and feeling depressed, often using sugary foods or drinks for an energy pick-up (especially in the afternoon).

William may feel that he has low motivation and needs tyrosine because he can’t get things done or he starts something and can’t complete it.

His intentions are good but he has to push himself or as he says “fight myself” to get things done. Because of this he feels tyrosine may be the next amino acid he should trial.

Why I would investigate and address low serotonin

William says he has anxiety and also has trouble sleeping. This could be related to low serotonin and/or low GABA.

However when someone has anxiety and insomnia and I hear the following words/phrases, I immediately think low serotonin should be investigated and addressed:

“My mind overthinks”
“I shut down with worry”
“I actually am AFRAID just thinking about taking Tyrosine”
“I fear so much”

All of the above can hold you back and look like low motivation when it is actually worry and fear that is holding you back.

Typically, with low serotonin, you could also second-guess things you do, experience negative self-talk, have a lack of confidence when doing things, get stuck because of perfectionism and may even feel like an imposter. You may also be very controlling and want to do it all yourself and not be willing to delegate – this can hold you back too.

All this and anything else on the list of low serotonin symptoms would further suggest we need to address this first.

Finding the ideal serotonin support for his needs

He is currently taking GABA, glycine and 5-HTP but still wakes at 3am. And he is still anxious.

I would work to optimize 5-HTP dosing (increasing every few days to see if more helps) or switch to tryptophan if the increased dose isn’t helping. Some folks do better one one versus the other and 5-HTP can raise cortisol in some instances causing a wired-tired feeling.

I’d do the same with GABA once the ideal dose of 5-HTP or tryptophan is found. This helps improve sleep and reduce anxiety too.

And I’d look into high cortisol in case this is causing his 3am awakenings.

Once he has ideal serotonin support for his needs, the overthinking will stop, the worry will go away and his fears will vanish – and he will be able to complete things he starts.

Being well rested because of a great night’s sleep is going to help a great deal too.

There may be a need for tyrosine now or later

I may be wrong and there may in fact be a need for tyrosine now. These cases illustrate tyrosine helping when it didn’t seem it would:

There may also be a need for tyrosine later and a trial will provide the answers.

Right now William is “AFRAID just thinking about taking Tyrosine” but once his serotonin levels are ideal he should no longer have this fear.

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

If you are new to using the amino acids tryptophan/5-HTP, GABA or tyrosine as supplements, here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution and a brief overview here, Anxiety and targeted individual amino acid supplements: a summary.

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 so you are knowledgeable.

As with all individual amino acids we use them for quick relief of symptoms. And we also always focus on the foundations like diet, the gut, adrenals and stress levels.

We appreciate William for asking this question so we all get to learn. Hopefully he’ll jump on and add to the discussion and share his results later.

Can you relate to his lack of motivation showing up as fear, worry and overthinking instead and holding you back?

What about these other low serotonin symptoms keeping you stuck: second-guessing, negative self-talk, lack of confidence, perfectionism, imposter syndrome and controlling?

Has using tryptophan or 5-HTP allowed you to get past some of this so you can get things done?

Did you also have to address low dopamine and actual low motivation, poor focus and fatigue with tyrosine?
