About Alpha-Glycerylphosphorylcholine
Alpha-Glycerylphosphorylcholine (Alpha-GPC) is a choline-containing compound available as a dietary supplement and nootropic, produced synthetically or extracted from soy lecithin. As a precursor to acetylcholine, it's investigated for its potential to enhance cognitive function, improve athletic performance, and aid in stroke recovery. Common dosages range from 300-600mg daily. While generally considered safe, potential side effects include heartburn, headaches, and insomnia. Further research is needed to fully elucidate its efficacy and long-term effects.
