- Tested brand
worth knowing

- Modest expected effect
what the evidence says
Phosphatidylserine earned its reputation from older trials in cognitive decline that used a bovine-derived form since withdrawn; the soy-derived form sold today has some supportive but weaker human data for memory in older adults and for blunting exercise cortisol. The honest position is cautious: plausible, historically supported, under-verified in its current form.
