The evidence in words
The verdict
For age-related memory, Phosphatidylserine earns evidence grade C (small effect, low consistency) — the evidence is limited or mixed. Older bovine data
How it might work
PS supports membrane fluidity and neurotransmission and may blunt the cortisol response to acute stress and exercise.
How to use it
100 mg ×3/day for cognition; ~600 mg/day for the cortisol/stress angle.
Safety & cautions
Well tolerated; mild GI upset or insomnia occasionally.
Bottom line
Modest for memory and more interesting for blunting exercise/stress cortisol. Reasonable, not compelling.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
