Phosphatidyl Serine (PS) is a naturally occurring phospholipid that is a critical component of cell membranes; it is found in especially high concentrations in the brain and nerve tissues. PS supports neuronal membrane fluidity and facilitates intercellular communication for healthy neurocognitive function.* In this way, PS supports the healthy utilization of acetylcholine, norepinephrine, serotonin, and dopamine in the brain.* Research shows that PS supplementation can promote cognitive function, mental acuity, and a healthy response to stress.* This Soy Free Phosphatidyl Serine is derived from sunflower oil. PS from sunflower oil is chemically indistinguishable from either soybean- derived or bovine-sourced PS and has a similar fatty acid profile. This makes it an ideal alternative for those who wish to avoid soy-based or bovine-derived PS products.
