Jarrow Formulas PS 100 provides 100 mg of phosphatidylserine (PS) per capsule, derived from sunflower lecithin rather than soy — making it a suitable choice for those avoiding soy-based ingredients. The phosphatidylserine used is Sharp-PS, a concentrated, stable form that Jarrow Formulas has selected for its quality and consistency. Each pack contains 120 capsules.
Phosphatidylserine is a naturally occurring phospholipid and a structural component of cell membranes, found in particularly high concentrations within brain tissue. This capsule format makes it straightforward to take alongside other daily supplements, with no mixing or preparation required.
Jarrow Formulas is a well-regarded US supplement brand with a long-standing commitment to quality manufacturing. PS 100 is well suited to those following a soy-free or sunflower-based supplement routine, including health-conscious adults and active individuals looking to round out their nutritional intake with a recognised phospholipid ingredient.
