About
Phosphatidylserine is an essential phospholipid component of neuronal cell membranes that supports cell-to-cell communication and neurotransmitter release. The FDA has granted a qualified health claim stating it may reduce the risk of cognitive dysfunction in the elderly. Studies show modest improvements in memory, learning, and mood in older adults.
How It Works
Essential phospholipid component of neuronal cell membranes; supports cell-to-cell communication, neurotransmitter release (acetylcholine, dopamine), and cortisol regulation; maintains membrane fluidity critical for signal transduction.
