Beetroot Extract Increases Endurance

Foods and supplements that increase nitric oxide production, such as beetroot extract, increases blood flow to the muscles. Nitric oxide is a gas released by the inner lining of blood vessels (endothelial cells) that is critical for regulating blood flow and blood pressure. This could increase the delivery of nutrients during and after exercise, which could improve performance and promote recovery. Several small, but well controlled studies found that beetroot extract improved aerobic capacity, endurance, and overall exercise capacity. (ACSM’s health and Fitness Journal, 17 (1): 29-30, 2013)
