Overview

NOW Foods Phosphatidylserine provides 100mg of phosphatidylserine (PS) — a phospholipid that is a critical component of brain cell membranes. PS is concentrated in the brain where it facilitates neurotransmitter release, receptor function, and synaptic activity. Clinical studies show PS supplementation improves memory, attention, and processing speed in older adults, and reduces cortisol levels after exercise. The FDA allows a qualified health claim: 'Phosphatidylserine may reduce the risk of cognitive dysfunction in the elderly.' It's one of the few supplements with an FDA-permitted brain health claim.
