Momentous Alpha GPC (Alpha-Glycerylphosphorylcholine) is a physician-formulated choline supplement delivering one of the most bioavailable and cognitively active forms of choline available — used by athletes, executives, and high-performers seeking to optimize acetylcholine synthesis, working memory, cognitive speed, and focus. Momentous is the performance supplement brand trusted by elite sports organizations and recommended by some of the world's leading neuroscientists and performance coaches.Alpha GPC provides the highest bioavailability of any choline supplement form — crossing the blood-brain barrier to directly elevate acetylcholine levels in the brain. Acetylcholine is the primary neurotransmitter of cognitive function, attention, working memory, and the neuromuscular junction — making Alpha GPC relevant for both cognitive performance and athletic output. Research supports Alpha GPC at 300–600mg for acute cognitive enhancement and at higher doses for long-term neuroprotection. Each capsule is precisely dosed for reliable, consistent delivery.
