Research Summary
Phospholipid research demonstrates significant promise for cognitive enhancement. Phosphatidylserine studies show improved memory performance in older adults and enhanced learning in younger populations. Meta-analyses support benefits for age-associated memory impairment. Phosphatidylcholine exhibits neuroprotective properties and supports acetylcholine synthesis. Evidence remains moderate overall; whilst human studies are encouraging, larger long-term trials are needed to establish optimal dosing and effects in diverse populations.
