Ingredient Information: Phosphatidylserine (PS) is a phospholipid naturally found in cell membranes, particularly abundant in the brain, traditionally sourced from bovine cortex but now primarily extracted from soy lecithin or sunflower seeds via enzymatic conversion or solvent extraction. Composed of carbon, hydrogen, nitrogen, oxygen, and phosphorus, it consists of a glycerol backbone, two fatty acid chains (e.g., stearic, oleic), and a serine-linked phosphate group, offering high bioavailability. It is processed into a stable, lipophilic powder for nutritional use.

Uses: Widely used in dietary supplements to support cognitive function, memory, and stress reduction, with clinical studies (e.g., 300 mg/day) showing improved recall in the elderly and reduced cortisol in athletes, rooted in its role in neuronal signaling. It is also employed in functional foods like energy bars and drinks to enhance mental focus and in sports nutrition for recovery and performance under stress.
