L-Alpha-Glycerylphosphorylcholine (Alpha-GPC) is a food-grade highly bioavailable choline compound that crosses the blood-brain barrier, used in cognitive-health, sports and clinical-nutrition applications.We supply bulk L-Alpha-GPC sourced from leading China manufacturers, available in powder and liquid forms for food and beverage manufacturers worldwide. Our L-Alpha-GPC is widely used in cognitive-enhancement supplements, focus formulas, sports nutrition, age-related cognitive-decline products and clinical nutrition.
Alpha-GPC is a natural phospholipid metabolite produced commercially by enzymatic hydrolysis of soy lecithin.
It contains approximately 40% choline by weight and readily crosses the blood-brain barrier, increasing brain acetylcholine levels. It is one of the most effective supplemental choline forms for cognitive enhancement, and also supports growth-hormone release.
