אלפא-GPC
Alpha-GPC is legal as a dietary supplement in the US and Canada but is a prescription medication in some European countries. A 2021 study found increased stroke risk with long-term use (10+ years), so extended daily use may warrant caution. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals prone to hypotension should consult a healthcare provider before use. Side effects are typically dose-dependent; start with lower doses and increase gradually.
