Product Overview
Alpha-GPC (L-Alpha Glycerylphosphorylcholine) is a specialized phospholipid and a natural precursor to acetylcholine, the neurotransmitter most associated with cognitive function and cellular signaling. While choline is found in many dietary sources, Alpha-GPC is highly valued in the supplement industry for its ability to cross the blood-brain barrier efficiently.
SRBio Alpha-GPC 99% is a high-potency, crystalline powder produced under strict quality controls. It is a cornerstone ingredient for manufacturers targeting the “Brain Health,” “Nootropic,” and “Sports Performance” categories, providing a clean-label source of bioavailable choline.

Key Advantages
1. Efficient Choline Delivery
Alpha-GPC is more effective at raising systemic choline levels than other sources like lecithin or choline bitartrate. SRBio Alpha-GPC 99% provides a concentrated payload, allowing for smaller serving sizes in finished products while maintaining high nutritional efficacy.
2. Versatile Metabolic Support
Beyond cognitive health, Alpha-GPC supports the natural production of growth factors and cellular membrane integrity. It is increasingly utilized in sports nutrition formulations to support focus and muscular power output during intense physical activity.
3. High-Purity Crystalline Structure
Our 99% purity grade is refined to remove residual solvents and by-products. This results in a stable, white powder with excellent organoleptic properties, making it easy to flavor in drink mixes or incorporate into premium capsule blends.
Manufacturing Excellence
Advanced Purification & Stabilization
Alpha-GPC is naturally hygroscopic (absorbs moisture). We utilize a specialized stabilization process and climate-controlled manufacturing environment to ensure the powder remains free-flowing and easy to handle during your production process.
