Phosphatidylserine
Phosphatidylserine shows promise for memory support and stress response in small studies, with some evidence it may help lower cortisol levels that spike during menopause. However, most research has been done in older adults with cognitive decline, not specifically in menopausal women. The evidence is mixed and limited, but the cortisol connection makes it worth considering as part of a broader stress management approach.

Overall: Mixed evidence
Randomised controlled trials
Several small randomized trials show modest improvements in memory and attention, but results are inconsistent and study quality varies.
Limited observational studies provide little additional insight beyond the controlled trials.
Meta-analyses suggest small cognitive benefits but acknowledge high variability between studies and potential publication bias.
Menopause-specific trials
No studies have specifically examined phosphatidylserine in menopausal women or for menopause-related symptoms.
What we do not know
No large studies have tested phosphatidylserine specifically in menopausal women. We don't know the optimal dose for stress reduction versus cognitive support. Most studies lasted only 6-12 weeks, so long-term effects are unknown. The majority of cognitive research focused on people with existing memory problems, not healthy midlife women. We also don't know how it interacts with hormone therapy or other menopause treatments.
How it is used
Common dose range
100-400mg daily
Notes on dosing
Take with food. Give it 6-8 weeks — cognitive benefits develop slowly.
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.
White beans
100 mg per cup
highest plant source
Soy lecithin
50 mg per tablespoon
common supplement ingredient
Chicken heart
45 mg per 100g
organ meats are richest sources
Atlantic mackerel
35 mg per 100g
fatty fish provide modest amounts
Mediterranean diet
Provides phospholipids from fish, nuts, and olive oil while supporting overall brain health
Whole food plant-based with legumes
White beans and soy foods offer the best plant-based sources
What depletes Phosphatidylserine
Chronic stress increases cortisol, which may deplete phosphatidylserine from cell membranes. High sugar intake and processed foods may interfere with phospholipid metabolism. Excessive alcohol consumption can also disrupt cell membrane integrity.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"The cortisol research is interesting, especially since stress hormones can wreak havoc during menopause. While the evidence isn't rock-solid, phosphatidylserine appears safe and may offer some support for both brain fog and stress response. If you try it, give it at least 8 weeks and pair it with proven stress-busters like regular sleep and movement."
