As we age, we have lower levels of nitric oxide (NO), leading to endothelial dysfunction , arterial stiffening, and a rise in blood pressure (hypertension) — three of the primary causes of cardiovascular disease. Some studies have shown the potential of NR in particular to reduce blood pressure and arterial stiffness.
