Nitric oxide. The heart health eSSeNtiaL.

It's impossible to maintain heart health without enough nitric oxide.

In 1998, three scientists won the Nobel Prize for their research related to nitric oxide (N-O) and, later, its role in cardiovascular health. At the time, the president of the American Heart Association called the discovery "one of the most important in the history of cardiovascular medicine."

N-O is the master regulator of your cardiovascular system. It's a signaling molecule which tells your blood vessels to relax, supporting your body's circulation and blood flow.

The good news: Your body naturally produces N-O in your youth.

The not-so-good news: By age 40, N-O production slows drastically, negatively impacting your circulatory health. It's impossible to have a healthy cardiovascular system without sufficient nitric oxide levels in your body.
