Epicatechin

Epicatechin is a naturally occurring flavanol found abundantly in cocoa, green tea, and certain fruits, and it has drawn considerable research interest for its potential cardiovascular and metabolic benefits. Studies indicate that epicatechin may support healthy blood circulation by promoting nitric oxide production, which helps relax blood vessels and improve blood flow. Research also suggests it may play a role in blood sugar regulation by enhancing insulin sensitivity, and emerging evidence points to possible benefits for muscle strength and growth through pathways involving follistatin and myostatin balance. Most clinical research has utilized cocoa flavanol extracts as the primary delivery form, and while early findings are promising across exercise performance and cardiometabolic health, larger and longer-term trials are still needed to fully understand its effects.
