Effects of a food supplement containing phosphatidylserine on cognitive function in Chinese older adults with mild cognitive impairment: A randomized double-blind, placebo-controlled trial
Journal of affective disorders (2025) · Rct · n=190
The capsule combined phosphatidylserine (63 mg/day) with α-linolenic acid, ginkgo flavonoids, vitamins B1 and B6 and folic acid, taken for 12 months. The effect cannot be credited to phosphatidylserine alone.

Phosphatidylserine for the Treatment of Pediatric Attention-Deficit/Hyperactivity Disorder: A Systematic Review and Meta-Analysis
Journal of alternative and complementary medicine (2021) · Meta analysis · n=216
Four studies met the inclusion criteria for the narrative review (n = 344) and three for the meta-analysis (n = 216).
The dose points come from one randomised, double-blind trial of 78 Japanese adults aged 50 to 69 with memory complaints (PMID 21103034), who took 100 mg or 300 mg a day of soy-derived phosphatidylserine or placebo for 6 months. Test scores rose similarly in all groups, placebo included, so neither dose is shown to beat placebo. Memory scores rose from baseline on both doses only in people with low baseline scores, a within-group result. No side effects and no change in blood markers were seen, which is why the ceiling is 300 mg. The PS-DHA memory trial (PMID 20523044, 157 older adults) states no dose, the 190-person trial in mild cognitive impairment (PMID 39317299) gave 63 mg inside a multi-ingredient capsule, and the pooled 200 to 300 mg effect on inattention (PMID 33539192) is in children with ADHD, so none of them can sit on this curve.
