Alpha-GPC

Silver· human data

Also known as: L-alpha glycerylphosphorylcholine

A choline source marketed for power output and focus, with early supporting data.

Alpha-GPC is a bioavailable form of choline that readily reaches the brain and supports acetylcholine production, which is the rationale for its use in both cognition and power-focused pre-workouts.

Some small trials report modest increases in explosive power and possible focus benefits, but the evidence base is early and studies are small. It is a plausible, better-than-average pre-workout ingredient rather than a well-established one.
