Alpha-GPC

Alpha-Glycerophosphocholine
Also known as: Alpha-GPC, Choline alfoscerate
Cognition

TL;DR

  • Potent choline source that increases acetylcholine levels in the brain

  • High evidence for improving cognitive function and power output

  • Moderate evidence for recovery after stroke and supporting memory

  • More effective than standard Lecithin or Choline Bitartrate

  • Moderate cost: ~$15-25/month

  • Best for: Focus, memory, athletic power

What it is

Alpha-GPC is a natural fatty acid found in the brain. It is the most 'bioavailable' way to increase levels of Acetylcholine—the primary neurotransmitter for learning, memory, and muscle contraction. It is effectively a 'precursor' to a sharper mind.
