Phosphatidyl Serine (PS) is a naturally occurring phospholipid derived from soy that plays a critical role in proper cellular membrane function.* It is especially important in the brain and nervous system where PS is critical for mental functions such as memory, attentiveness, and reaction time.* Ginkgo biloba may support brain health through its powerful free radical scavenging activity, as well as through other biological mechanisms.*
