Phosphatidyl serine (PS) is a naturally occurring phospholipid that is found in especially high concentrations in the cellular membranes of brain and nerve tissues.* PS supports neuronal membrane fluidity and facilitates intercellular communication for healthy neurological and brain function.* PS thus supports the normal utilization of neurotransmitters in the brain.* Research shows that PS supplementation can promote cognitive function and mental acuity.* This product utilizes Sharp- PS®, which is derived from non-GMO sunflower oil and is soy free.
