When our tissues need additional blood supply, like during exercise, or when we’re stressed, our blood vessels need to dilate efficiently. If blood vessels are not as elastic as they should be, then our health can suffer. The production of nitric oxide is very important to blood vessel health.* When an adequate amount of nitric oxide is produced in our blood vessels, the vessels are more elastic, normal blood pressure can be maintained, sexual arousal occurs normally, and cardiovascular health is promoted.* Thorne supplements enhance the body’s production of nitric oxide, thus promoting healthy blood vessels.*
