What the Evidence Says

AI-generated · Qwen 3.6 · methodology

L-Citrulline and beet root extract have strong evidence for improving blood flow and exercise performance via nitric oxide production. Hawthorne extract and L-Norvaline are included to support cardiovascular function, though research evidence for these specific components is more limited. The overall profile focuses on enhancing vasodilation and nutrient delivery to muscles.
