Giving NO back to the blood vessel to mediate its beneficial effects is not straightforward. However, we have shown that dietary inorganic nitrate, both as a capsule and a dietary intervention with nitrate-rich beetroot juice, has a number of beneficial effects in CVD states. This beneficial effect is mediated through it's endogenous conversion from nitrate to nitrite in the mouth, and then from nitrite to NO via nitrite reductases within the blood vessel. We have shown benefit of inorganic nitrate in pre-clinical models of CVD, early mechanistic studies in healthy volunteers, and anti-inflammatory benefits in patients with hypertension, hypercholesterolaemia and those suffering acute heart attacks.
