What it's actually good for

Focus

Research Supported

Increases acetylcholine levels to support attention.

Muscle

Research Supported

Shown to increase power output and growth hormone secretion.

Longevity

Weak Evidence

Studied for cognitive decline but lacks evidence for general lifespan extension.

How it works

Alpha-GPC is a highly bioavailable choline source that effectively crosses the blood-brain barrier. Research supports its use for enhancing power output in athletes and improving cognitive function in clinical populations.

It acts as a precursor to acetylcholine, a key neurotransmitter for focus and muscle contraction, and provides phospholipids for cell membrane health.

Safety

  • May increase TMAO levels with long-term use
  • Can cause depressive symptoms in sensitive individuals
  • Potential for headaches if over-dosed
