Nitric Oxide - why so important?

Nitric Oxide is a very simple molecule, yet critically important to our longevity and, in men, sexual health.

We do not consume Nitric Oxide directly; it is produced inside our blood vessels, to be exact by the lining of the blood vessels, called epithelium.

Nitric oxide is produced by nearly every type of cell in the human body and one of the most important molecules for blood vessel health. It's a vasodilator, meaning it relaxes the inner muscles of your blood vessels, causing the vessels to widen. In this way, nitric oxide increases blood flow and lowers blood pressure.
