Description
Alpha-Glycerylphosphorylcholine (Alpha-GPC) is a highly bioavailable choline donor used for cognitive and neuromuscular support. Alpha-GPC crosses the blood–brain barrier and fuels acetylcholine synthesis for attention, learning, focus, and working memory. Alpha-GPC also supplies choline for phospholipid remodeling that helps maintain neuronal membranes and signal transduction. Athletes use Alpha-GPC to support reaction time, accuracy, and peak power via improved neuromuscular drive. Common in nootropic and performance formulas, Alpha-GPC complements dietary choline from eggs, fish, and soy.

Alpha-Glycerylphosphorylcholine [Alpha-GPC]
Warnings
Alpha-glycerylphosphorylcholine may cause headache, restlessness, vivid dreams, or mild GI upset in cholinergically sensitive users. Alpha-Glycerylphosphorylcholine requires medical guidance for people with seizure disorders, bipolar tendencies, or those on anticholinergic, antihypertensive, or psychiatric medications; avoid near bedtime if alerting. Alpha-Glycerylphosphorylcholine is not recommended in pregnancy or breastfeeding without professional advice.
Food Sources
Alpha-glycerylphosphorylcholine in supplements is typically derived from lecithin (soy or sunflower); dietary choline sources include eggs, fish, meats, and dairy.
Time Frame
Members unlock simple timing guidance (with meals vs empty stomach, morning vs evening where it matters), keeping it consistent and practical without over-prescribing exact schedules
