Supplement
5-HTP
5-HTP shows promising results for mood and sleep during menopause, with several small studies finding meaningful improvements in depression scores and sleep quality. The biological mechanism makes sense — declining estrogen disrupts serotonin pathways, and 5-HTP provides the building blocks to restore them. While the research is still limited, this supplement may be worth trying if your mood feels flat or heavy rather than anxious, especially combined with other serotonin-supporting strategies.

Overall: Mixed evidence
Randomised controlled trials
Several small randomized trials show significant improvements in depression scores and sleep quality, though effect sizes vary and some studies show only modest benefits.
Observational studies consistently link higher tryptophan intake and serotonin precursor availability with better mood outcomes.
Meta-analyses of 5-HTP trials show statistically significant improvements in depression symptoms compared to placebo, though confidence intervals are wide.
Menopause-specific trials
Limited studies in menopausal women show promise, but most mood research has been conducted in younger adults or mixed populations.
What we do not know
We lack large-scale studies specifically in perimenopausal and postmenopausal women. The optimal dose for menopause-related mood changes has not been established through rigorous trials. Most studies have been 8-12 weeks long, so we don't know about long-term safety or effectiveness. We don't have head-to-head comparisons with other mood supplements like SAM-e or St. John's wort. The interaction effects with hormone therapy have not been systematically studied.
How it is used
Common dose range
50-300mg daily
Notes on dosing
Start at 50mg and increase slowly. Do not combine with antidepressants or triptans without medical supervision.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
Turkey
200 mg tryptophan per 3 oz serving
High-quality protein with good tryptophan content
Pumpkin seeds
110 mg tryptophan per 1 oz
Also rich in magnesium which supports serotonin production
Milk
95 mg tryptophan per 1 cup
Contains calcium that aids tryptophan uptake
Bananas
11 mg tryptophan per medium banana
Also provides vitamin B6 needed for serotonin synthesis
Oats
35 mg tryptophan per 1 cup cooked
Complex carbs help tryptophan cross blood-brain barrier
Mediterranean diet
Rich in tryptophan-containing fish, nuts, and whole grains while supporting overall brain health
Balanced protein intake
Regular protein throughout the day provides steady tryptophan availability for serotonin production
Complex carbohydrate timing
Eating carbs with protein helps tryptophan cross the blood-brain barrier more effectively
What depletes 5-HTP
High sugar intake disrupts serotonin balance and depletes B vitamins needed for synthesis. Excessive alcohol interferes with tryptophan metabolism and depletes B6. Chronic stress increases cortisol, which breaks down tryptophan. Artificial sweeteners may disrupt serotonin pathways. Very low-protein diets provide insufficient tryptophan precursors.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"If your mood has shifted from bright to gray during this transition, 5-HTP offers a biologically sound approach with some solid research backing. The evidence isn't overwhelming, but it's encouraging enough — and the mechanism clear enough — that many women find it worth trying. Start low, be patient, and remember that building back your serotonin pathways often works best as part of a broader approach."
