About Alpha GPC + Pramiracetam
Alpha GPC or choline alfoscerate is a precursor to acetylcholine, the neurotransmitter, and it "has significant effects on cognitive function with a good safety profile and tolerability" (Traini, Bramanti, and Amenta, 2013). Pramiracetam faciliatates the rate of acetylcholine turnover and stimulates brain activity in the hippocampus. Alpha GPC increases choline availability and Pramiracetam increases choline uptake and use making them particularly effective together.
