claimWhile once thought to be metabolically inert in mammals, it is now clear that nitrate can be reduced endogenously, although the primary contribution under normal conditions comes from external microbial sources.

claimCrucially, this second reduction step is markedly enhanced by low pH and hypoxia, conditions that prevail in contracting skeletal muscle, thereby elegantly coupling NO production to metabolic demand at the precise time and location it is needed.
