self-doubt

Tryptophan calms comfort eating, eases self-doubt, reduces uncontrollable late night snacking and results in a lot more peace around food.

Zoe shares her life long story about comfort eating, her insecurities and self-doubt in her teens, the comfort-foods that allowed her to “escape” and how addressing low serotonin at 41 years of age led to her feeling a lot more peace around food. The effects of one chewable tryptophan were instant! Here is her story in her own words, some insights from me and possible next steps for Zoe to consider.

Historically I had comfort eaten and felt insecure and had lots of self-doubt. This led to trying alcohol and cocaine in my early 20s, plus I’m a vegetarian so I think I blew through all my natural serotonin by the time I tried tryptophan at 41!

I think [low] serotonin was huge for me and tryptophan helped calm my comfort eating.

My comfort eating started at secondary school, around 14, an escape from my feelings when I got home from school. I would eat mashed potatoes with loads of butter or a Sara Lee Chocolate gateau.

Thinking about it now, I realize I was craving carbohydrates and I would eat till I felt sick. I craved feeling really full and sadly was bulimic for a few years there as a teenager. I think my feelings of not feeling good enough/unloved drove me to comfort eating and not feeling understood. I would eat, be sick then do an exercise video before my parents even got home! It may also have been hormonal as I get PMS. I also have PCOS (polycystic ovarian syndrome).

Good news is I tried tryptophan last summer and the effects were instant.

I hadn’t read the instructions properly so ate a Lidtke chewable tryptophan tablet with my meal and instantly felt the effect. I stopped eating and feeling hungry instantly. I took the chewables for a couple of months then went onto Lidtke 500mg for another few months.

I do still have a tendency to snack late at night but it’s gone from totally uncontrollable 8 or 9 out of 10 to a 3 or 4 out of 10. I don’t crave food anywhere near as much as I used to and I have a lot more peace around food now.

Thank you for being the one to introduce me to them, you are a super star.

A few thoughts from me

This is a wonderful outcome and I’m thrilled for her transformation! I also appreciate Zoe giving me permission to share here so you can be inspired and have hope!

A few thoughts from me:

PMS/dysphoria is common with low serotonin levels and research shows that tryptophan can help ease symptoms in a few cycles
Low levels of serotonin and endorphins can lead to alcohol consumption and experimenting with drugs as a means of self-medication. This can often be replaced with sugar addiction and cravings which are also a way to self-medicate.
Low serotonin is a factor with bulimia, although it’s typically an under-recognized factor when it comes to eating disorders.

I share where I’d start if we were working together and possible next steps below.

How did she use tryptophan and which products did she use?

Zoe initially used the Lidtke chewable (each one is 100mg) for a few months: ”I used the Lidtke chewable as I don’t need much to feel the effects of aminos!”

Then she switched to the Lidtke 500mg: “I was taking 500mg mixed with banana on an empty stomach every day for about 6 months.”

This amount of tryptophan would be considered low for most folks. 500mg is a typical starting dose often used 1-2 mid-afternoon and 1-2 in the evening.

You may see all her low serotonin symptoms and think she has a lot going on and will likely need large doses of tryptophan for serotonin support. But you never know how much tryptophan will work until you do a trial.

Low endorphins and DPA for eliminating comfort eating

Zoe actually posted much of the above in response to a question I posted on Facebook about eliminating comfort eating and the amino acid called DPA (d-phenylalanine). DPA typically helps the kind of eating where you feel “I deserve this or this is my reward or this is my treat.” Until you address low endorphins with DPA, you may also feel eating these foods are numbing – as in numbing or blocking emotional pain.

She shared “Yes I’ve tried DPLA and it had a very nice effect.” But as you’ve read above, low serotonin was a bigger issue for Zoe and it was the tryptophan that really helped calm her comfort eating.

DLPA or DPA?

I reminded her that DPLA (dl-phenylalanine) is quite different from DPA (d-phenylalanine). DLPA works on boosting low catecholamines (improving low motivation, poor focus and fatigue and stay-in-bed kind of depression) and to a small extent also low endorphins. DPA works purely on boosting low endorphins.

But Zoe did see benefits from DLPA:

DPLA made me feel very content with my life. I felt very happy where I was all of a sudden, instead of feeling the need to chase something better all the time. I’ve never had just straight DPA, I’ve found it hard to find.

It’s not uncommon to see low serotonin and low endorphins in situations like this.

Tryptophan is no longer helping: my feedback and other ideas

Zoe did also share this about the 500mg tryptophan no longer helping like it used to:

The tryptophan doesn’t seem to have the same effect on me anymore sadly but that maybe because I’m ‘topped up’ but I did wonder if I had ruined the quality of my tryptophan by storing it on top of my microwave (so they were heating up).

I’ll try the [Lidtke] Tryptophan Complete this time and hope they work as I do still get a bit of PMS which seemed to go away for a while.

I did hear about mixing it with inositol being a possible solution too?

Here is my feedback on some of this, where I’d start if we were working together and possible next steps:

My favorite DPA product is also made by Lidtke and it’s called Endorphigen. It may help with the last remaining snacking
However, timing wise late-night snacks for carbs tends to be low serotonin. I would try again with Lidtke 500mg (the microwave heat may have been an issue), considering a trial of 1000mg, trialing the Lidtke Tryptophan Complete (as she may be missing the cofactors to make serotonin) and even consider going back to the chewable Lidtke tryptophan which worked so well initially.
I would also look at other factors that may be lowering serotonin levels: has gluten snuck back in or is there any accidental exposure? Has she started consuming collagen and/or gelatin which can lower serotonin in susceptible folks?
I would consider trialing inositol if there is an obsessive tendency to the snacking. It does help with PCOS too.
She had said “I thought GABA would be amazing for me but it wasn’t.” Since GABA helps with PCOS and PMS, I would revisit GABA trials using different forms, higher doses and making sure trials are sublingual. Progesterone or herbs that support progesterone is another option.
I agree with Zoe’s comments about being a vegetarian. Low levels of neurotransmitters are common and we cover the benefits of grass-fed red meat for women in my interview with Dr. Felice Jacka on the first Anxiety Summit. I’d encourage adding some quality animal protein if she’s open to it.
For vegetarians, we often also add a free form amino acid blend with tryptophan, especially if adding animal protein is a no-no.
I would also consider pyroluria (the social anxiety condition) too as PMS is common, pyrolurics are often vegetarians, and the pyroluria protocol provides necessary cofactors for making serotonin. Zinc is often low in vegetarians too.
I would also assess for low iron and low B12 (also often low in vegetarians) and needed for serotonin production; and look into the BCP (birth control pill) or other meds that may be lowering serotonin.
I would have her doctor check thyroid health as low thyroid can reduce the effectiveness of the amino acids

As with everyone, a full functional workup looking at diet, nutritional deficiencies, digestion, all hormones, toxins and infections (and so on) is key to address all possible root causes.

Have you found that tryptophan calmed your comfort eating, reduced your self-doubt and late night carb snacking and led to feelings of peace around food? Did it also reduce PMS and other low serotonin symptoms?

If you’re a practitioner working with women who comfort-eat and have typical low serotonin symptoms, have you found tryptophan to help?

Imposter syndrome and neurotransmitter support: I feel like the person I’m supposed to become

February 26, 2021 By Trudy Scott 9 Comments

imposter syndrome and neurotransmitter support

A newly qualified nutritionist posted wonderful feedback on a blog post on imposter syndrome and low serotonin with tryptophan as one possible solution. She shared how neurotransmitter support with tryptophan, tyrosine and GABA was her solution, eliminating her imposter syndrome and social awkwardness in 2 weeks. Here is the feedback Yo shared on the blog:

Thanks for your work on neurotransmitters, Trudy. I am a fan. I had suffered BADLY from imposter syndrome at the end of my nutrition degree and I felt socially awkward in so many outings and situations. My anxiety and stress were through the roof! VERY bad sleep, stressed and my digestion was very poor.

Fast forward to a year later after addressing my sleep (no. 1 priority); stress levels; diet; loads of minerals; vitamin supplementation – my health started to shift for the better, but I still had the imposter syndrome hanging over my head.

What really tipped the balance was the supplementation of tyrosine, tryptophan & GABA. The imposter syndrome seemed to have vanished within two weeks. And it was in your blogs that had pointed out clues to the amino acids I was needing to supplement.

I feel like the person I’m supposed to become and I can’t thank you enough for the amazing work you’ve been doing. I will definitely be following your journey, learning more about these neurotransmitters, and sharing this information so that others can benefit from it. Thank you, thank you!

I thanked Yo for her kind words and for sharing this wonderful outcome. I always say we all deserve to feel our absolute best so I love that she says “I feel like the person I’m supposed to become”!

Addressing neurotransmitter imbalances with targeted amino acids

I also congratulated her on doing the foundational work first. As she discovered, even with all that in place, we often still have to address neurotransmitter imbalances with targeted amino acids too. With regards to imposter syndrome and the amino acids she used:

Using tryptophan to address low serotonin eases worry, rumination, anxiety, negative self-talk, self-doubt and and not feeling capable – all of which we’d typically associate with imposter syndrome
Using tyrosine to address low dopamine results in more motivation and better focus so you are more likely to finish tasks (and therefore feel more confident and capable). Many folks report a feeling of calm focus with tyrosine too
Using GABA to address low GABA eases physical tension and overwhelm and helps stop unwanted thoughts.

A 2-week turnaround is fabulous and means she found the right combination of amino acids and ideal doses for her unique needs right away. I’ve seen results like this in 2 weeks but doing a new amino acid trial each week would usually take at least 3 weeks. I suspect her results were so fast because of the foundational work that was in place.

I typically start with amino acids trials on day one of working with someone, while we are working on diet, sleep, stress – this would have led to her feeling like the person she was meant to become much sooner and would have helped with sleep, stress and dietary changes too. Her approach worked but it took longer to get results.

Questions I still have about the amino acid trials

I have these questions I posed to Yo and hope to hear back as I feel these answers may be helpful as you navigate your own challenges with imposter syndrome:

Did she do a trial of one amino acid at a time (my preferred approach so you know exactly what effects each one has)?
Or did she start taking all 3 amino acids at once and why?
What doses were ideal for her unique needs and how quickly did she find the ideal doses
Is she continuing with a maintenance dose?
Also, since she mentioned social awkwardness I have to wonder if the pyroluria protocol would be of added value (if any of the social awkwardness still remains)? This protocol helps to make neurotransmitters.

I’ll report back once I get Yo’s feedback.

If you’re new to imposter syndrome

If you’re new to imposter syndrome, here is a definition from Intellectual Self-doubt and How to Get Out of It:

People with imposter syndrome often feel like they are not as capable or adequate as others perceive or evaluate them to be. The signs and symptoms are feelings of phoniness, self-doubt, and inability to take credit for one’s accomplishments. It is a form of intellectual self-doubt. Those with imposter syndrome are often intelligent and high achievers – like many academics, pharmacists, and professional students. On one hand, imposter syndrome provides motivation to persevere. On the other hand, you over prepare and overwork.

This author shares a link to the Clance Imposter Scale. This is a self-assessment of imposter syndrome, developed by Dr. Pauline Rose Clance and Dr. Suzanne Imes (who worked together and coined the term “Impostor Phenomenon”.).

This paper reports that

Imposter syndrome is common among early career nurse researchers and often has a considerable impact on those affected. It can cause various problems, including anxiety, self-doubt and feelings of inadequacy, and therefore has significant potential to adversely affect personal and professional development.

You can also read more about imposter syndrome on my previous blog post on this topic – Imposter syndrome and low serotonin: is tryptophan the solution? and the Harvard Business review definition:

Imposter syndrome can be defined as a collection of feelings of inadequacy that persist despite evident success. ‘Imposters’ suffer from chronic self-doubt and a sense of intellectual fraudulence that override any feelings of success or external proof of their competence.

The numbers of papers on imposter syndrome are increasing but there is still no mention of biochemistry or neurotransmitters so these amino acid success stories are adding to the body of knowledge. (I would love to get them published as case studies so if you can help please do let me know.)

I love hearing life-changing stories like this and I am sharing it here to inspire and offer hope! I also love that Yo is such a fan now and wants to pay it forward by sharing this information with clients so I also shared my amino acid practitioner training.

Is imposter syndrome new to you? And is this concept of addressing imposter syndrome with amino acids new to you? If you have a question we would appreciate hearing:

#1 How you describe your imposter syndrome and how it impacts your life

#2 How you score on the Clance Imposter Scale (and which aspects bother you the most)

#3 What symptoms you have on the Amino Acid Questionnaire in the low serotonin, low catecholamine and low GABA sections.

If you already know about imposter syndrome and have found a solution with the amino acids please do share your success story so we can all learn from each other, as well as inspire and offer hope. We would appreciate hearing:

#A How you described your imposter syndrome and how it impacted your life

#B How you scored on the Clance Imposter Scale before and after using amino acids (and which aspects bothered you the most)

#C What symptoms you had on the Amino Acid Questionnaire in the low serotonin, low catecholamine and low GABA sections (before and after using the amino acids)

#D Which amino acids were most helpful and how much of each amino acid helped you

#E If you’ve also had CBT (cognitive behavior therapy) and how it helped too

Imposter syndrome and low serotonin: is tryptophan the solution?

February 28, 2020 By Trudy Scott 75 Comments

No-one is talking about the biochemical and low serotonin aspect of imposter syndrome and the role tryptophan plays. This really does need to be part of the discussion and part of the solution.

In case you aren’t familiar with the term imposter syndrome, many of my clients who appear to have very successful careers will say to me … “I feel like I’m an imposter. They’re going to catch me out at what I’m doing. I’m not really as good as everyone thinks I am.” Perhaps you can relate to this? You just don’t feel that you’re good enough – you’re faking it until you make it and putting on a brave face.

An article published on Psychology Today states that these “feelings of inadequacy are surprisingly common” and cites the results of a 2020 systematic review: “62 studies with over 14,000 participants found that a staggering 56 percent to 82 percent of individuals, across genders, backgrounds, and ages, experienced imposter feelings at some point.^“

Valerie Young’s excellent book, The Secret Thoughts of Successful Women: Why Capable People Suffer from the Impostor Syndrome and How to Thrive in Spite of It, [my Amazon link] has created the awareness we need and offers so much in terms of recognizing the way imposter syndrome manifests in our lives. She shares these examples which you may also resonate with:

From the high-achieving Ph.D. candidate convinced she’s only been admitted to the program because of a clerical error to the senior executive who worries others will find out she’s in way over her head, a shocking number of accomplished women in all career paths and at every level feel as though they are faking it – impostors in their own lives and careers.

This article in Harvard Business Review, Overcoming Imposter Syndrome, states

Imposter syndrome can be defined as a collection of feelings of inadequacy that persist despite evident success. ‘Imposters’ suffer from chronic self-doubt and a sense of intellectual fraudulence that override any feelings of success or external proof of their competence.

The article mentions phrases such as “I must not fail”, “I feel like a fake” and “it’s all down to luck”, offering these tools: recognize the imposter feelings, reframe, talk about how you feel, be kind to yourself, visualize success and seek support.

This is all great advice but it’s hard work when you’re already struggling. And what if there was a simple solution that involved addressing low serotonin with an amino acid supplement such as tryptophan or 5-HTP?

How you will feel if your serotonin is low

If your serotonin is low you WILL feel like this: plenty of self-doubt, lack of confidence and negative self talk. It’s common to feel anxious and inadequate, have ruminating thoughts, do lots of reprocessing and overthinking, and be a perfectionist (you may get stuck because of the perfectionism and overthinking things). This often occurs together with carb cravings (especially late afternoon and evening), PMS/perimenopausal/menopausal symptoms. Insomnia is common and this is when much of the ruminations and negative self-talk occurs.

There is a very simple solution. Figure out if low serotonin is the issue and address it with tryptophan or 5-HTP. Using co-factors like zinc, vitamin B6, iron, magnesium, and diet and lifestyle changes may be necessary too. Other neurotransmitter imbalances like low GABA, low endorphins and low dopamine may also be factors.

I can relate to all this personally. I had a very successful corporate job in my late 30s and I started to feel sure I was useless and that I was going to lose my job. I felt like they were going to figure I didn’t really know what I was doing despite my leadership abilities! Then the dreadful perimenopausal symptoms and anxiety and panic attacks started. And then I figured out it was low serotonin, low GABA and hormone imbalances, and a number of other root causes that contributed to my low neurotransmitters. I list many typical root causes below.

Why is serotonin low (and address the root causes)

You need to figure out why serotonin is low and address this. Low serotonin may be caused by many factors such as:

dysbiosis and a messed up microbiome (we make so much serotonin in the gut)
stress and the adrenals (cortisol affects your sex hormone production)
the birth control pill (which lowers zinc and vitamin B6, both of which are needed for serotonin production)
gluten issues (leading to low serotonin and other nutritional deficiencies)
not consuming enough quality animal protein (amino acids are the building blocks of our neurotransmitters, and grass fed red meat provides zinc, iron and omega-3s – all needed to make serotonin)
low stomach acid (meaning you can’t digest the protein you’re consuming)
sex hormone imbalances (serotonin and estrogen are very closely linked)
liver issues (affecting how you process xenoestrogens)
low bile production (so you’re not digesting the healthy fats you’re eating)
statins (leading to cholesterol that is too low)
not getting enough exercise, sunshine or nature
mold exposure
heavy metal toxicity
Lyme disease and other co-infections
and more

I’ve poured through the research on imposter syndrome and there is no mention of serotonin. A few articles – like this one in Forbes, Why You Need To Understand The Neuroscience Of Imposter Syndrome – do mention serotonin and dopamine:

feelings of “not deserving” correlate with lower levels of the neurotransmitter serotonin which relates to mood, and low levels of dopamine which are connected to reward and motivation

There is no mention of tryptophan (or 5-HTP) or any of the above approaches for raising serotonin (other than exercise) or tyrosine to help raise dopamine. However, clinically we see all the signs of imposter syndrome disappear once low serotonin is addressed, and motivation improve once low dopamine is addressed.

Update July 2024: A paper published shortly after this blog was published, Focusing on the Neuro-Psycho-Biological and Evolutionary Underpinnings of the Imposter Syndrome, does mention the need to explore the role serotonin and other neurotransmitters:

exploring the serotonin, oxytocin, and dopamine systems among imposterism sufferers could be a worthy research pursuit. Likewise, it would be intriguing to know how these neuro-hormones and other bioactive molecules are functionally interconnected, and how they are related to the feelings of self-doubt in the syndromal imposters.

Based on my experience, I suspect research will eventually confirm that low serotonin is a major factor with imposter syndrome but also that many other neurotransmitters play a role too – with low levels of oxytocin, dopamine, endorphins and GABA. The above paper also mentions a possible role of cortisol and sex hormones. And just as we see with anxiety, fears and worries, the combination of root cause factors will likely be unique for each person.

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 too). This is a paid online/virtual group program where you get my guidance and community support.

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