Phosphatidylserine, often shortened to PS, is a phospholipid ingredient used in functional food and dietary supplement applications. For B2B buyers, the most important sourcing questions are source, specification, document availability, manufacturing capability, and application fit.
Nutranexa positions PS as a lead product developed through cooperation with East China University of Science and Technology. The ingredient is described as being made from natural lecithin and L-serine through bio-enzymatic conversion.
Buyers should request verified specifications, COA, packaging details, and intended application support before placing a purchase order.
