Generally accepted with some debate
"Animal and in vitro studies show promising effects, but human studies at supplement-relevant doses are less conclusive. There is a plausible mechanism of action via nitric oxide production."
Epicatechin is a flavonoid with antioxidant properties that may support cardiovascular health and muscle growth. It works by increasing nitric oxide production, which helps to dilate blood vessels, improving blood flow and nutrient delivery to muscles. However, more research is needed to confirm these benefits at typical supplement doses.
