Our take on the Jarrow Formulas PS 100

Jarrow Formulas PS 100 is a phosphatidylserine supplement in capsule form, 120 capsules per bottle, marketed for stress and brain support. Phosphatidylserine is a phospholipid found in cell membranes, especially in the brain, and is one of the better-studied supplements for memory and cortisol response. Jarrow's version is gluten free and soy-derived, a common source for phosphatidylserine. It suits adults looking for a single-ingredient cognitive and stress supplement rather than a stacked nootropic blend.
