Exploring the Impact of Alternative Sources of Dietary Nitrate Supplementation on Exercise Performance.

An increase in the level of nitric oxide (NO) plays a key role in regulating the human cardiovascular system (lowering blood pressure, improving blood flow), glycemic control in type 2 diabetes, and may help enhance exercise capacity in healthy individuals (including athletes). This molecule is formed by endogenous enzymatic synthesis and the intake of inorganic nitrate (NO) from dietary sources. Although one of the most well-known natural sources of NO in the daily diet is beetroot (), this review also explores other plant sources of NO with comparable concentrations that could serve as ergogenic aids, supporting exercise performance or recovery in healthy individuals.
