Sponsor's own description
Red Spinach is a natural food which is a rich source of nitrates, which are beneficial in hemodynamics, cardiovascular function, and have natural hypotensive and antianginal effects. Red spinach extract has been shown to be beneficial in exercise performance, albeit mostly in aerobic exercise. In a previous study in our lab, we found that dietary nitrate consumption resulted in significantly greater isometric force production in teenage males. However, currently there is little know regarding the effects of dietary nitrate supplementation on isometric strength, resistance exercise and cognitive performance.
