Alpha GPC Dosage and Purity
Alpha GPC is the star for boosting acetylcholine, which fuels learning and memory. Look for a dosage between 300 mg and 600 mg per serving, as clinical studies often use these amounts.

L-theanine promotes calm focus by increasing alpha brain waves. For stacking, aim for at least 100 mg per serving, ideally with a pure source. PeakPury delivers 900 mg per serving (split across three capsules) plus added alpha GPC and phosphatidylserine. When combined, alpha GPC and L-theanine create a balanced state of alert relaxation, perfect for demanding tasks.
