Choline source supporting acetylcholine synthesis and power output.
What it is
Alpha-GPC (alpha-glycerophosphocholine) is a highly bioavailable choline compound that crosses the blood-brain barrier efficiently.
How it works
Provides choline for acetylcholine synthesis; supports phospholipid membrane integrity and growth hormone secretion.
What the evidence says
Moderate evidence for cognitive support; emerging evidence for power output in athletes.
Safety Notes
- Hygroscopic — store in cool, dry place. Some people report headache at higher doses (choline excess).
- anticholinergic drugs: May counteract drug effects.
