Phosphatidylserine

Phosphatidylserine (CAS 1446756-47-3), commonly abbreviated as PS, is a phospholipid naturally occurring in cell membranes and sourced commercially from soy or sunflower lecithin.

It functions as a bioactive lipid ingredient in nutritional and pharmaceutical formulations targeting cognitive and neurological support. PS is the primary active ingredient in cognitive health supplements.

In capsules, softgels, and functional foods, it is standardized to defined phosphatidylserine content for label claims. In pharmaceutical and nutraceutical manufacturing, it is incorporated into formulations.

These applications target memory, mental focus, and age-related cognitive decline. Personal care formulators use PS as a membrane-active moisturizing agent in premium skin care products.

Its phospholipid structure supports skin barrier function and ingredient delivery. Biotechnology and cell culture applications rely on PS as a membrane component in liposomal drug delivery systems.

Phosphatidylserine is supplied as a fine powder or oil-based concentrate, with powder forms being the most common for supplement manufacturing. Standard commercial grades are typically standardized.

These grades are available at 20%, 50%, or 70% PS content, derived from soy or sunflower sources. Food-grade and USP-referenced specifications are available for industrial use.

Soy-free sunflower-derived grades are increasingly sought for allergen-sensitive formulations. These high-purity options ensure compliance with modern safety and labeling requirements for global markets.
