Nitric Oxide (NOX) Nitric Oxide is used to help dilate blood vessels and is used in the treatment of high blood pressure. It may also help people suffering from angina (poor blood supply to the heart), poor circulation, age-related dementia, and Raynaud’s syndrome. You can not buy it as a supplement but you can buy it in precursor forms that convert it in your body: Potassium Nitrate, Citrulline, and L arginine. They are generally found in capsules or powdered forms, alone or in combination formulas. Visit - https://www.nationalnutrition.ca/heart-circulatory-health/nox-nitric-oxide.html #NitricOxide
