Skeletal muscle nitrate storage – the missing piece of the nitrate supplementation puzzle?

Abstract

Over the last decade, nitrate (NO3−) supplementation – delivered as beetroot juice (BRJ) or sodium/potassium nitrate – has gained widespread attention for its potential as a therapeutic and ergogenic aid (Jones et al. 2018). Specifically, NO3− supplementation has been shown to reduce blood pressure and improve exercise performance (Jones et al. 2018). These benefits have been attributed to an increase in nitric oxide (NO) bioavailability following exogenous NO3− intake.
