When using GABA for anxiety does tolerance increase and which amino acid to use for a low mood?

By 2 Comments

gaba and tolerence

Today I’m sharing some great questions I’ve received about GABA and serotonin support for anxiety and low mood, and my feedback to give you some ideas on what to look for as you use the amino acids for your own issues (or with clients/patients if you’re a practitioner).

I cover possible reasons for ongoing low GABA levels, long-term use of the amino acids, low mood associated with menopause, problems with mainly sugar- and gluten-free, the role of the adrenals and thyroid, the amino acids I’d start with for low mood, how lithium orotate may help, how to know if collagen is causing a low mood and making you more anxious, and some resources for you.

GABA tolerance has increased

Gaba has been a lifesaver for my anxiety! I also use taurine sometimes for anxiety too, and that has helped too. Right now, I take 1000 mg [of taurine]. As for GABA (I now take 1000 mg of that also) I have noticed that my tolerance for it has increased.

Here is my feedback: I’m really pleased GABA and taurine are helping ease your anxiety. I have not seen tolerance to be a factor with my clients using GABA and I’m not aware of any research on this topic. I would look into what could be depleting GABA at a faster rate so you seem to need more and more.

This could be caused by:

  • increased stress which lowers zinc and increases cortisol
  • poor gut health and dysbiosis (there is a bacteria in the gut that may consume GABA – it’s called gabavorous)
  • low zinc and low B6 (which are needed to make GABA and other neurotransmitters)
  • toxin exposure (we’re now seeing that GABA has a protective effect – this blog covers have GABA is protective of the thyroid after fluoride exposure)
  • thyroid problems (the amino acids are less effective in this instance)

Keep in mind that long-term use of the amino acids is not the plan. Once the diet is addressed and the other underlying biochemistry, nutrient deficiencies, toxins etc. are addressed they should no longer be needed. At most, an occasional “top-up” may be needed.

Low mood associated with menopause

Which amino acids would you recommend for low mood associated with menopause? No panic attacks but a crashing low mood for 24hrs or more before slight recovery, a few easy days and then the cycle begins again. Diet is mainly sugar- and gluten-free. Any suggestions would be appreciated, thank you

Here is my feedback: When I hear “diet is mainly sugar- and gluten-free” with mood swings I always look into gluten exposure and blood sugar dips. Keeping a food mood log is an easy first step to see if the low mood is tied to what is being eaten and when.

I would recommend the complete removal of gluten and sugar. Gluten can trigger depression, anxiety, OCD and lead to many psychiatric symptoms. Blood sugar swings can cause both depression and anxiety. The amino acids make it easy to quite sugar and gluten – no willpower required and no feelings of deprivation. Do the questionnaire and do a trial of the amino acids that apply. Based on the above symptoms I’d suspect tryptophan and tyrosine may help and are always a good first step while everything else is being figured out.

I would also look at adrenal function as they take up the slack in menopause and rule out Hashimoto’s thyroiditis and Graves (as you can get mood swings with both as the thyroid levels shift).

Low lithium can also cause mood swings too and lithium orotate can help to keep an even mood, allowing the amino acids to be more effective.

Finally, I’d want to know if collagen, gelatin or bone broths have recently been added to your diet and are being consumed in an on-an-off pattern that correlates with the low mood. Certain susceptible individuals find that it lowers serotonin and increases depression and anxiety, and causes insomnia.

Next steps are a full workup looking at sex hormones, low zinc, low B6, low magnesium, the gut, EMFs, sleep and other dietary factors like salicylates, histamine, glutamates etc. We look at all the possible 60+ nutritional and biochemical root causes and address them or rule them out.

It’s also important to have a good support system in place for those very low days – friends and family members, being part of a community and even keeping a mental health support line number close at hand.

And of course, I always say this: get out in nature, get some exercise, hug someone and have a good laugh.

Resources for you

  • My book The Antianxiety Food Solution (my Amazon affiliate link) has an entire chapter on the amino acids GABA, tryptophan, tyrosine, and DPA (and how to use them), a chapter on blood sugar balancing and glutamine and a chapter on gluten issues (and much more).

Sjogren’s syndrome: tryptophan and GABA for anxiety, and moisturizing for dry skin and inflammation?

By 19 Comments

sjogren's syndrome

A few weeks ago I blogged about a new pilot study about the use of a skin moisturizer twice a day reduced inflammation in older adults. I use the inflammation research to question if this may be applicable and helpful for you if you suffer from anxiety, extrapolating that it may well be given the added benefits of touch and an oxytocin boost.

I received a number of great questions about how to apply this information and have decided to share a question from someone with both Sjogren’s syndrome and anxiety, in order to illustrate how I’d work with someone like this.

Here is the question I received:

I would like to know how much of one’s body needs to be moisturized, and if it is also necessary to be done twice per day? Such a simple but effective way to help with anxiety. Will be slathering a lot more in the future! I have Sjogren’s so everything is dry – skin, mouth, eyes, hair. I have been trying to keep my face much “moister” and I am sure my wrinkles have lessened. I find rice bran oil is also quite good.

I’m going to address her moisturizing question below and share more about anxiety in Sjogren’s syndrome and some nutritional solutions, but first let me explain what Sjogren’s syndrome is.

An overview of Sjogren’s syndrome

Let me explain what Sjogren’s (SHOW-grins) is in case you’re not familiar with this condition. It’s an autoimmune condition and is described as follows on the Mayo Clinic site:

often accompanies other immune system disorders, such as rheumatoid arthritis and lupus. In Sjogren’s syndrome, the mucous membranes and moisture-secreting glands of your eyes and mouth are usually affected first — resulting in decreased tears and saliva.

Although you can develop Sjogren’s syndrome at any age, most people are older than 40 at the time of diagnosis. The condition is much more common in women.

The site goes on to say that other than dry eyes and mouth, some people experience joint pain and stiffness, swollen salivary glands, skin rashes or dry skin, vaginal dryness, persistent dry cough and prolonged fatigue. It’s worth a read to learn more about complications like more dental cavities, yeast infections, vision issues, problems in the lungs, kidneys or liver, the risk of lymphoma and peripheral neuropathy.

My feedback about moisturizing

In the study, moisturizing was done twice a day. I’m not sure how much of the body needs to be moisturized but if everything is dry, I’d want to moisturize as much as possible.

Given that chronic inflammation is a major factor in Sjogren’s and other autoimmune conditions like systemic lupus erythematosus, it’s feasible to expect similar benefits in terms of reduced inflammation. Hopefully we’ll see research on autoimmune conditions in the future.

When it comes to anxiety, I do want to make it clear that I was and still am extrapolating from the research on inflammation and measuring reduced anxiety was not part of the study. Moisturizing may or may not help with anxiety and I certainly wouldn’t only use this intervention.

Anxiety in Sjogren’s – low serotonin and GABA?

You may not be aware that anxiety/depression is very common in Sjogren’s. In one study they

found 33.8% patients with anxiety, and 36.9% had depression, which were significantly higher than controls.

I use a comprehensive nutritional and lifestyle approach to help my clients ease their anxiety and as I mention above, I would not only rely on moisturizing.

I would use the serotonin questionnaire to determine if low serotonin is contributing to the anxiety (the worry-in-the head and rumination type of anxiety) and do a trial of tryptophan or 5-HTP.

Interestingly, a number of studies suggest the involvement of the serotonin system in the development of Sjogren’s, with one study reporting

Significantly lower platelet levels of serotonin in Sjogren’s patients as compared to healthy controls.

They didn’t find a correlation between the levels of serotonin and how severe the Sjogren’s symptoms were, which falls in line with what we know about biochemical individuality and why doing a trial of tryptophan or 5-HTP (to find your ideal dose) is the best approach for serotonin support.

I would use also the GABA questionnaire to determine if low GABA (physical tension type of anxiety) is a factor, and do a trial of GABA.

If you recall, in the Mayo Clinic description above, stiffness is a common symptom of Sjogren’s and GABA eases stiffness.

I haven’t found any research on GABA in Sjogren’s, but one case study reports that a patient experiencing athetoid movements (a movement dysfunction, characterized by involuntary writhing movements), reported symptom improvement with hydroxychloroquine, pilocarpine, gabapentin, and clonazepam. The latter two medications work on the GABA system.

You can find the tryptophan and GABA products I use with my clients here.

Poor sociability in Sjogrens – could this be related to pyroluria?

A study published earlier this year is reportedly the first study to conclude that patients with Sjogren’s score “high on neuroticism and anxiety and low on sociability.”

If social anxiety is a concern, I’d have her do the pyroluria questionnaire and address this if needed.

If you recall, in the Mayo Clinic description above, joint pain and dental cavities are common symptoms. These are also very common with pyroluria, so using a nutritional approach helps ease the social anxiety, and improves joint issues and mouth health.

The other factor that makes me suspect pyroluria may be common in Sjogren’s is that it’s considered a systemic connective tissue disorder, together with systemic lupus erythematosus and rheumatoid arthritis. You can read more about pyroluria and connective tissue disorders on the pyroluria prevalence blog and the Ehlers Danlos/joint hypermobility blog.

Poor mouth health is also common with histapenia/low histamine so I’d want to look into this too.

You can find the pyroluria supplements I use with my clients here.

Sjogren’s and the Autoimmune-Paleo diet

Since Sjogren’s is an autoimmune condition, following an Autoimmune-Paleo (AIP) diet is key too. Here are some books that are well-worth making part of your library, even though they are not specific to Sjogren’s syndrome they offer support for autoimmune conditions (and many individuals often have more than one autoimmune disease)

Here is one more resource for you: The Autoimmune Masterclass which airs online this weekend It’s a similar format to online 7-day summits but runs for 2 days instead and is no-cost to attend during these two days.

I haven’t dived into the research on all the other autoimmune conditions and the above connections (low serotonin, low GABA and pyroluria) but it’s highly likely similar connections exist. So, if you have any autoimmune condition and anxiety this could all apply for you too.

If you have been diagnosed with Sjogren’s syndrome please share if GABA and tryptophan have helped ease your anxiety, and if the pyroluria protocol has helped you with social anxiety?

And let us know if moisturizing is helping your dry skin and possibly reducing inflammation and anxiety too?

Sleeping through the night for the first time in many years: a trial and error approach to find the ideal tryptophan product

By 22 Comments

If you have trouble sleeping through the night (or even have anxiety or panic attacks), finding the nutritional/biochemical root causes and addressing them is going to provide relief but it’s not always straightforward to find your root cause or causes (there are often more than one). Also, what works for you today may not work for you in 2 years time and may not work for your friend who has similar symptoms. You have to be a detective yourself and/or work with a health professional who can put all the puzzle pieces together.

I recently read a Facebook comment where someone was really frustrated about all the trial and error work that may be involved:

I’m just so tired of all this trial and error work trying to figure out why I’m anxious and depressed can’t sleep more than 4 hours a night. It’s been going on way too long I just want answers and a solution to all this. Enough already!

While I feel for this woman, I do acknowledge that it can sometimes be challenging to put all the puzzle pieces together. Other times we are able to figure things out very quickly. I’d like to share some feedback from Lorraine on the tryptophan-PMS-anxiety blog to illustrate how one small change made a big difference for her and it was a matter of trial and error.

Lorraine shares her great results with this Tryptophan Complete tweak for her insomnia:

Trudy, after listening to your talks about Lidtke Tryptophan I decided to give the Tryptophan Complete a try. I’ve taken one capsule each on the last two nights instead of two of the Tryptophan 500mg caps. Both nights I slept straight through all night and had a hard time waking up in the morning. I’ve struggled with insomnia for many, many years. The 500mg Lidtke Tryptophan supplements were helping but I was still waking up during the night. For me to sleep all night is almost miraculous.

I’ve been also taking Progesterone (low on testing), Magnesium, L-Theanine and Melatonin.

I recently added phosphatidylserine, and Holy Basil because saliva testing showed high cortisol at bedtime and off the charts high in the morning. I’m hoping to start eliminating some of those other supplements now that I’m sleeping so well.

I want to thank you for the Anxiety Summits and your book and updates on Facebook and newsletters. I have learned so much from you!

I’ve blogged about which product to use for boosting serotonin: Tryptophan 500mg or Tryptophan Complete (by Lidtke)?. I share this

  • I like to have my clients do a trial of the amino acidsso they can find the ideal dose for their needs and right now I still feel this would still be the best approach to take – using 500mg tryptophan. Once you have figured out you do well with tryptophan-only product and have your dose, then consider reducing it slightly after about 2-3 weeks and adding in additional Tryptophan Complete.
  • The other option is this: if you don’t get the expected results with Tryptophan 500mg, then try the Tryptophan Complete. You may need the other ingredients for it to work well for you.

Lorraine chose to do the latter – switching to Tryptophan Complete – since she didn’t get ideal results with Tryptophan 500mg and it worked for her. I will add that even though she slept straight through all night, I don’t like that she had a hard time waking up in the morning and when that happens, I recommend less tryptophan. It’s very possible that the ideal combination would be 1 x Tryptophan 500mg and 1 x Tryptophan Complete (my first suggestion).

Here is my quick commentary on the other products she’s using for her insomnia:

  • Progesterone and theanine: Testing progesterone levels are important before using progesterone. Both theanine and GABA support GABA production and when GABA is low, we often see low progesterone. With both low GABA and low progesterone, sleep and anxiety can be worse.
  • Magnesium: This mineral is commonly low and is needed to make both serotonin and GABA.
  • Melatonin: This is made in the body when there is sufficient serotonin and may not be needed long-term once she has good levels of serotonin (which the tryptophan product/s are helping her make).
  • Phosphatidylserine and holy basil: High cortisol is a common root cause of both insomnia and anxiety and saliva testing is an excellent way to confirm this. Phosphatidylserine can be used to lower high cortisol although I have found even better results with a phosphorylated serine product called Seriphos. Holy basil or tulsi is an adaptogenic herbal product that provides adrenal support helping with sleep problems and easing anxiety and stress.

In Lorraine’s case, her insomnia was caused by low serotonin (hence the need for tryptophan, melatonin and magnesium), low GABA/low progesterone (hence the need for progesterone, theanine and magnesium) and high cortisol (hence the need for phosphatidylserine and holy basil).

She shares she’s hoping to start eliminating some of these other supplements now that she’s sleeping so well. So, this would be another trial and error approach, stopping and/or reducing one at a time and seeing how she does. Or she may well find she needs to continue with everything for some time.

As you can see, for Lorraine it was a matter of trial and error to find her solution, but it was well worth it to get the “miraculous results” she experienced: sleeping though the night for the first time in many years!

Some of these products may work for you but it’s going to be a matter of trial and error to find your root cause/s and solution.

In case they are relevant for you, these products mentioned in this blog can all be found in my online Fullscript store:

I’d love to hear how you’ve used a trial and error approach either on your own or with the help of your practitioner to find the nutritional solution for your insomnia and/or anxiety?

If you’re a practitioner, please do share an example of how you’ve used this approach with a client or patient.

If you’ve had frustrations with this trial and error approach, please share them too.

Feel free to post your questions here too.

Using amino acids for anxiety and depression: does the right dose ever change or need a tweak?

By 8 Comments

If you are using targeted individual amino acids for anxiety and/or depression and doing well on them, you’ll likely get to the point when you’re asking questions like how to discontinue them and does the right dose ever change or need a tweak, especially after some stressful life events. Amy posted this question in the comments section of the blog on using tyrosine to create a sense of calm energy (paraphrased and formatting for ease of reading)

Trudy you are a God send! I stumbled upon your work after following Julia Ross. I have depression and anxiety. I’m currently taking:

1000 mg tyrosine 2x daily

500 mg glutamine morning, 1000mg mid-morning and afternoon

500mg DPA (Endorphigen) 3 x daily (previously I was using DLPA but your recommended DPA was so much better and less stimulating)

50 mg 5-HTP afternoon and

1500mg tryptophan at night

I used the amino acids to treat what used to be referred to as “atypical” depression: loss of motivation, tiredness, lethargic, intense carb craving, feelings of guilt and hopelessness. I would become paralyzed with depression, barely able to get through the days. When I was younger I treated these episodes with antidepressants but as I got older could no longer tolerate the side effects. I’m also still on birth control pills at the age of 46 and believe I may be in perimenopause but can’t stop the pills for medical reasons.

Tyrosine gave me my energy back, glutamine cut the carb cravings. DPA and True Calm work wonders for my anxiety.

I watch my sugar intake and always consume lots of animal protein. I’m so grateful for this solution.

After trialing this seems to be the right combo. I always get confused when is it time to discontinue supplements? Do you stop or slowly reduce or taper?

Does the “right” dose ever change? I’ve been on this combo about 2 months. I’ve felt great but some anxiety/panic creeping back up …. wondering if supplements need a tweak or is this just the result of some stressful life events. Advice appreciated!

I was really pleased to hear the wonderful results she was having and glad that she had trialed the amino acids to find the correct amount for her unique needs and situation. I don’t see this happening often enough and it really is the most effective way to get results. It’s what I do with all my clients – methodical, step-by-step trialing of each amino acid, one at a time and carefully documenting results (both good and bad) in order to find the optimal dose of each one.

When and how to discontinue the amino acids?

To answer her question about when and how to discontinue this is my feedback:

Once you are feeling back to your old self with no more anxiety, panic attacks or depression, you may choose to stop everything at once, but I prefer to slowly lower the amount of one amino acid at a time and add back if your symptoms come back. They don’t need to be “tapered” but doing it this way it helps with preventing your original anxiety and depression symptoms going back to really bad in one big swoop and having to start all over again.

I will add that I have had feedback from someone saying when she stopped tryptophan abruptly she felt the same withdrawal effects as when she weaned off meds but based on my experience this is very rare.

After posting her question Amy made some adjustments – taking less of all of them. As I mentioned above I find it better to lower the amount of one amino acid at a time – kind of reverse of the trialing method you use when starting the amino acids. Also, since she mentioned she felt anxiety/panic creeping back up, I would have expected her to increase some of the calming amino acids.

Does the right dose ever change or need a tweak?

And to answer Amy’s other question: does the right dose ever change or need a tweak?

Yes, the “right dose” can change based on stressful life events especially if you have pyroluria – stressful life events can cause you to dump more zinc and vitamin B6 affecting serotonin and GABA production and increasing the social anxiety.

Amy does mention that she’s on the birth control pill and this depletes zinc and vitamin B6 and hence serotonin) and has an impact on the microbiome – so this may well be playing a role in the need to tweak doses.

There are many other factors that could lead to the need to adjust the amino acids (or other supplement protocols):

  • hormonal changes like PMS, perimenopause or menopause
  • something contributing to leaky gut like adding back gluten or accidental exposure to gluten
  • antibiotics (affecting the microbiome and serotonin/GABA levels)
  • artificial sweeteners (because of their effect on the microbiome and hormones)
  • starting on other medications (since many cause nutritional depletions)
  • adding in a new food like collagen/gelatin (for some people collagen and gelatin may lower serotonin levels)
  • running a marathon (it likely depletes zinc and may ramp up cortisol)
  • a formulation changing completely without you knowing (one example is Seriphos – used to lower high cortisol – where the core ingredient changed completely and the labeling stayed the same)
  • a product changing from using gelatin to cellulose capsules (this may be problematic if you have SIBO)
  • you move into a new home and get mold exposure
  • you get a new dog or cat and start using Frontline Plus for fleas (fipronil, the active ingredient, targets GABA receptors and recent research points to increased anxiety, aggressive behavior, memory problems)
  • you have started using a sauna (depletion of zinc and other minerals, as well as stirring up toxins)
  • your need for serotonin support increases as you head into winter-time (some low serotonin folks are more susceptible to the winter blues)
  • a recent course of fluoroquinolone antibiotics (impacts on magnesium and GABA levels and the mitochondria)
  • you may no longer need them

This is not a complete list of reasons that could impact you but this will give you an idea of what to start to think about.

Hopefully this shows how important it is to monitor how you’re doing and adjust as needed (either up or down) and think about what is changing in your life.

If you’d like to read about the amino acids products Amy uses – the same ones I recommend and use with clients – you can find them listed on my supplements blog.

We appreciate Amy for allowing me to share her results and posting these questions which are a great learning opportunity for you.  She shared this with me:

I hope my “story” is helpful. Keep doing this important work! I work in the behavior health field. My colleagues think this is radical thinking and continue to only support the medical model. I’ve done a lot of my own research and trial and error. I wish there were more-open minded clinicians.

Hopefully with success stories like this, all the nutritional psychiatry research and behavioral health practitioners like Amy who have experienced it first hand and/or with clients/patients and family, we’ll change how mental health care is approached.

Do success stories like this lead you to be more open-minded about anxiety nutrition solutions? Have they worked for you?

And have you found the ideal dose of amino acids and then needed to adjust them up or down based on any of the above? How methodical were you in doing your adjustments?

How do I taper tryptophan without withdrawal symptoms: a tight band around my head, brain zaps and agitated free-floating anxiety?

By 14 Comments

I have not had any clients experience the need to taper or slowly wean their tryptophan dose or report tapering side-effects similar to those they experienced when tapering off an antidepressant. However, I recently had someone ask this question on the blog (and then had someone else ask a similar question) so I’m sharing these questions and my responses in the hope of gleaning some additional information (and educating you if this applies to you). I never say never and am always learning. I’m also very interested to know how common this is and what some of the underlying factors could be.

Here is the question that was asked by Lara (we’ll call her Lara) and slightly paraphrased for clarity:

I’ve been taking 1500 mg of tryptophan for 3 months, and it has helped a lot with sleep and depression. I dropped to 1000 mg about a week ago then 500mg just to see how I’d do without it. I didn’t think it was numbing my feelings, but I am experiencing a return of feeling good.

I’ve been on antidepressants before and I am feeling the same withdrawal effects as when I weaned off meds. This is exactly why I chose to not go back to pharmaceuticals. It was difficult to wean off. How do I taper tryptophan without experiencing withdrawal symptoms? Thank you for your valuable knowledge.

These are the kinds of questions I’d ask a client in this situation:

  • Was the 1500mg helping and which low serotonin symptoms were eased?
  • How did this change when you reduced to 1000mg and then reduced to 500mg? i.e. did the low serotonin symptoms come back?
  • Which antidepressant are you comparing these affects to? And how long ago did you wean off the antidepressant?
  • Which brand of tryptophan you are using? (I find Lidtke is the best quality)

Keep in mind that we always want to be sure it’s not a one-off situation. In order to be sure someone is observing mild adverse effects from a supplement I’ll often have my client stop it and then add it back to make sure. And sometimes more than once.

In this instance repeating the process may be a good idea i.e. going back to 1000mg and then 1500mg and then reducing again, carefully documenting in a food mood supplement log.

It turns out that Lara was using the Lidtke tryptophan and she was seeing wonderful benefits for her low serotonin symptoms with none of the typical SSRI side-effects:

the 1500mg before bed with a small carb helped me get to sleep and stay asleep. It also helped with anxiety and depression during day. I tend to be a worrier, have social anxiety, and get stuck with negative thoughts about myself and others. And have very little interest in life.

I was on Zoloft from 2005 – 2009. Got off of that and did Lexapro for only 6 months in 2012. The Zoloft was life changing for me but I did not like the side effects and being on an antidepressant for the rest of my life.

The tryptophan is superior to these SSRIs [selective serotonin reuptake inhibitors] – no sexual side effects, no weight gain, or anhedonia [inability to feel pleasure in normally pleasurable activities].

She describes how she reduced the tryptophan and how her withdrawal symptoms were similar to those she experienced when tapering off her SSRIs in the past:

The withdrawal effects were felt when dropping from 1500mg to 1000mg, to 500mg, then zero over 2 days and they lasted about 3 days. By the 4th day I was no longer feeling bad.

The symptoms are hard to explain – it felt like a tight band around my head, also brain zaps (this is a common SSRI withdrawal symptom many describe feeling in their head).

The worst of it was a deep agitated free-floating anxiety like you’re walking along the edge of a cliff and there’s a physical pain in your gut. Fortunately, it was only present from waking up till around 2pm.

These are questions I’d ask or wonder about

As I mentioned in the introduction, I have not had any clients experience the need to taper or slowly wean their tryptophan dose or report tapering side-effects similar to those they experienced when tapering off an antidepressant. But if this is an issue some individuals experience I’d like to know about it

I’d also like to know how long the tapering side-effects of tryptophan last and how severe the symptoms are. In Lara’s case the symptoms were pretty severe but fortunately they only lasted 3 days which is very much shorter than SSRI tapers.

There could be confounding factors and here are additional questions I’d ask or wonder about if a client experienced similar adverse tapering effects. These are questions you could ask yourself if you have experienced this when stopping tryptophan abruptly:

  • Could the prior use of SSRI prescriptions be a factor? (but I have worked with many clients with prior use of SSRIs and not have tryptophan tapering issues)
  • What else has changed in terms of stress, diet, hidden gluten exposure, or even the something like a recent introduction of collagen (which may deplete serotonin levels in susceptible folks)?
  • Are there hormonal changes that could affect serotonin levels – like in a woman with PMS or perimenopausal or menopausal symptoms? (again, I’ve worked with many women of all ages and haven’t observed this to be an issue)
  • If you are prone to the winter blues and reduced winter serotonin, could stopping the tryptophan in the winter play a role? (I have had clients have SSRI tapering issues in winter because of being prone to the winter blues and choose to work with their doctors on their SSRI taper in the spring and summer for this reason)
  • Could this also be an issue with summer blues in hot states like Arizona?
  • Could any of these play a role: a recent medical procedure, a course of antibiotics (especially fluoroquinolones) or antifungals, poor gut health, a new infection, decreased immunity or increased inflammation?
  • Could low levels of these nutrients play a role: vitamin B6, ferritin, magnesium and zinc?
  • Would using high doses of vitamin C during the “taper” help reduce some of the symptoms? (this works well as an antidote when you take tryptophan and don’t need it and want to negate some of the negative effects, so may help in this situation)

Stopped tryptophan and felt very angry and down

The other question I had about tryptophan weaning is this one from someone who shared that she had suggested tryptophan for a friend. This friend was

experiencing a lot of ruminating and anxiety. She responded beautifully and felt great. About a year later, she tried to stop taking it, and said she felt very angry and down. Is there a weaning process for the tryptophan?

This could possibly be related to the above and you could pose similar questions but based on on what I see with clients I feel this is more of a matter of stopping the tryptophan too soon while she still had low serotonin – especially if the ruminating and anxiety came back. Feeling angry and down are classic signs of low serotonin.

The questions asked were specifically about tryptophan but they could also possibly apply to some individuals who stop 5-HTP abruptly.

I’d love to hear if you’ve experienced anything like this with either tryptophan or 5-HTP and if yes please share your answers to some of the above questions.

Right now, I’m afraid I don’t have an answer for you on how to taper tryptophan without these withdrawal symptoms: a tight band around the head, brain zaps and agitated free-floating anxiety. Right now, I’m not sure how big an issue this is. If it is common, I’m hoping some of the feedback I receive may provide some answers.

Tryptophan promotes charitable donating

By 2 Comments

This 2014 study is one of my all-time favorite applications of tryptophan, an amino acid I use extensively with anxious clients. The goal of the study, Tryptophan promotes charitable donating, was to investigate the link between serotonin and charitable giving, something the authors consider to be “one of the most important elements of prosocial behavior.” They offer this quote by Molière:

Every good act is charity. A man’s true wealth hereafter is the good that he does in this world to his fellow.

In this study they tested whether charitable donating or giving can be promoted with the use of the amino acid tryptophan, the biochemical precursor of serotonin:

Participants were compared with respect to the amount of money they donated when given the opportunity to make a charitable donation.

Additional information about the study

Here is some additional information about the study, where the study group was given 800mg of tryptophan:

Thirty-two healthy international south European students (mean age = 21.8; 4 male, 28 female; mean Body Mass Index = 21.5, range 17.8–30.8) with no cardiac, hepatic, renal, neurological, or psychiatric disorders, personal or family history of depression, migraine and medication or drug use participated in the experiment.

Sixteen participants (2 male, 14 female) were exposed to an oral dose (powder) of 0.8 grams [which is 800mg] of tryptophan – which roughly corresponds to the amount of TRP contained in 3 eggs–and 16 (2 male, 14 female) to 0.8 grams of microcrystalline cellulose, a neutral placebo. These doses were always dissolved in 200 ml of orange juice.

The donating task was standardized, without the presence of an experimenter, and with a fixed amount of money in a fixed number of notes and coins:

…Participants were not informed beforehand that the donating task was part of the experiment. Donating behavior was measured by the amount of money the participant donated. After having received 10 Euros… for their participation in the study, participants were left alone and asked whether they were willing to donate part of their financial reward to charity. Four money boxes (Unicef, Amnesty International, Greenpeace, and World Wildlife Fund) had been positioned on the table.

Here are the results:

As expected, compared to a neutral placebo, [tryptophan] appears to increase the participants’ willingness to donate money to a charity.

The serotonin oxytocin connection

The authors mention the “functional and anatomical interactions between serotonergic and oxytocinergic systems” and that “it may be likely that the willingness to donate money to a charity is modulated by the effect that serotonin exerts on oxytocin levels.”

My perspectives

I always like to add my perspectives on studies like this so here goes. We know that because tryptophan boosts serotonin it’s going to improve mood and reduce anxiety, worrying and fears. When you feel better, lighter, happier and calmer you feel like anything is possible and I can see how this could translate to feeling more caring and wanting to be charitable.

The authors do mention how low serotonin is correlated with “antisocial behaviors such as social isolation and aggression.” Anger and irritability is also something we see when serotonin is low. Of course, these are also antisocial behaviors.

Here is the amino acid questionnaire with the low serotonin section.  I’d like to add this new sign to the questionnaire and wonder what would work: Lack of charitability? No desire to give to charity?  

One additional comment is that with the work I do, the amino acids are used when you show signs of low serotonin such as anxiety or worry or depression or insomnia or afternoon/evening cravings. I use the trial-response method to determine if you’ll actually respond to tryptophan i.e. experience benefits and how much you will need to see those benefits. I starting dose is typically 500mg tryptophan and I have found the Lidtke brand to be the most effective. You can read more on tryptophan here.

Because of this I’m intrigued with this application of using tryptophan in healthy individuals. But I’d also be cautious based on what I’ve seen with clients who don’t need serotonin support and take tryptophan – they can feel too sleepy or even more sad or more anxious. This would be my hesitation in saying we should give everyone tryptophan in order to create a more charitable and giving society. I do however agree with the authors about the importance of a quality real whole foods diet with adequate quality animal protein, saying the study result:

supports the idea that the food we eat may act as a cognitive enhancer modulating the way we think and perceive the world and others.

The lead author, Professor Laura Steenbergen, works in the Cognitive Psychology Unit, Institute for Psychological Research and Leiden Institute for Brain and Cognition, Leiden University Leiden, Netherlands, as is doing some very interesting research with amino acids, cognitive enhancement and mood improvement. It’s really exciting!

We’d love to hear if you feel more charitable and giving when you take tryptophan or 5-HTP (since it also boosts serotonin)?

And if you feel more charitable and giving when you eat a quality real whole foods diet with adequate quality animal protein?
