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.
Let me share what I see with the women with PMS that I work with:
- This is very typical when I’m working with someone with PMS and anxiety and other mood symptoms. It typically takes 2 to 3 cycles for an amino acid like tryptophan to have an impact on PMS itself. But it does typically start to work right away on the less severe anxiety and mood symptoms that may also be a factor during the rest of the month.
- I don’t start with 6g per day of the tryptophan but rather have each person do the amino acid questionnaire, review the precautions and do a trial of tryptophan, increasing as needed to find the optimal amount for their needs (you can read more about this here on anxiety and the amino acid overview
- We often find that adding GABA helps too, as this supports progesterone production
- Many anxious women I work with also have pyroluria or signs of low zinc and low vitamin B6 and adding these nutrients, together with evening primrose oil, provide additional hormonal support (and help with the social anxiety).
- Other factors to consider with PMS: low total cholesterol (as cholesterol is needed to make hormones), gluten issues, adrenal function and blood sugar control, gut health and the microbiome, and liver support
- And finally, we can’t forget diet and need to switch to eating a real whole foods diet free from sugar, gluten and caffeine. Coffee and chocolate in the second half of the cycle can be especially problematic for many women
Together with the tryptophan and the above approaches (if needed as we are all so different), it’s not unreasonable to get the reduction of symptoms from 34.5% (as seen with the tryptophan) down to 100%. It breaks my heart when I hear women think they have to live with PMS symptoms when they don’t have to!
Additional resources when you are new to using tryptophan, GABA, and other amino acids as supplements
As always, I use the symptoms questionnaire to figure out if low serotonin or low GABA or other neurotransmitter imbalances may be an issue.
If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.
There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control (this is covered in an entire chapter too), sugar cravings, anxiety and mood issues.
The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs.
If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms). This is a paid online/virtual group program where you get my guidance and community support.
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 used tryptophan for PMS? Do you take it all month or just in the 2nd half of your cycle? What about other changes that have helped: GABA or liver support or quitting caffeine? Or something else? Please share.
