The Active Ingredient Is: Alpha-GPC (AlphaSize)

Alpha-GPC is a choline-containing compound that helps the brain produce acetylcholine, a neurotransmitter linked with learning and memory processes.

This variant is AlphaSize branded and provides choline through a phospholipid glycerol backbone, helping delivery to the brain for cognitive support.

What Does Alpha-GPC Do?

Dr. Krzysztofiak from the University of Warsaw found that Alpha-GPC quickly delivers choline to the brain, supporting acetylcholine synthesis which is important for learning and memory. This aligns with EFSA-style thinking on the role of choline in brain function.

Alongside phosphatidylserine, Alpha-GPC supports brain cell communication and membrane integrity, helping maintain normal information processing and mental performance in daily tasks.
