Phosphatidylserine (1989, '14, '15) & Alzheimer's
Phosphatidylserine is key to proper brain function. Combined with phosphatidic acid (from soy lecithin) it improves memory, mood, and cognition in the elderly, and has a general stabilizing effect in AD patients. In other studies, it improves mood, brain function, learning memory, and vocabulary in people with Alzheimer's. Additionally, cholinesterase and hippocampal inflammation injury decreases.
