About

Alpha-GPC is a highly bioavailable choline source that crosses the blood-brain barrier to serve as a precursor for acetylcholine, the primary neurotransmitter for learning and memory. Clinical studies in elderly patients show improvements in cognitive function scores, and it is used as a prescription drug in several European countries.

How It Works

Provides highly bioavailable choline that crosses the blood-brain barrier; serves as a precursor to acetylcholine, the primary neurotransmitter for learning and memory; promotes neural tissue health and enhances neuronal communication.
