Nitric oxide is an emerging secret for powerful cardiovascular protection. Only recently identified, scientists were awarded a Nobel Prize in 1998 for their discoveries concerning nitric oxide as a signaling molecule in the cardiovascular system. Since that time, significant evidence has come forward on its incredible potential and myriad uses.
As a potent vasodilator, nitric oxide expands the arteries which in turn helps regulate blood pressure and enhance the blood flow to vital organs. Nitric oxide is naturally produced in the endothelial cells of the arteries, but as a gas, it only has a lifespan of a few seconds. When nitric oxide levels in the arteries become deficient, the barriers break down, cardiovascular protection is lost, and the heart is more susceptible to defect.
Nitric oxide can not be brought in from the outside, but its production can be stimulated through amino acids and antioxidants such as arginine and citrulline. These elements can markedly boost production of nitric oxide and stabilize the molecule, preventing it from being inactivated by oxygen radicals.
