l citrulline converts into nitric oxide. nitric oxide is what viagra and cialis stimulate the body to make. the sun also stimulates the capillaries beneath the skin to make nitric oxide.
Young people make nitric oxide in abundance but the body’s production in both men and women declines with age.
Nitric oxide is what enables the blood vessels of the body to expand and contract with each contraction of the heart. as nitric oxide levels decline—the blood vessel’s ability to expand and contract declines. Blood pressure rises. This is true for both men and women.
Both men and women need to supplement or otherwise increase their levels of nitric oxide as they get older.
