GSA Beetroot 1300

Beetroot powder (from Beta vulgaris root) is naturally rich in inorganic nitrate, betalain pigments, and polyphenols that support nitric‑oxide–mediated vasodilation, healthy blood flow, and cellular antioxidant defenses (Clifford et al., 2015; Milton‑Laskibar et al., 2021).

In healthy adults, randomized controlled trials and meta-analyses show that nitrate‑rich beetroot intake can assist athletic performance by lowering the oxygen cost of exercise, improving time‑to‑exhaustion, and enhancing endurance, particularly in recreationally active individuals (Lansley et al., 2011; Domínguez et al., 2017). Multiple clinical trials and systemic reviews also indicate that regular beetroot or beetroot‑juice consumption aids healthy circulation by lowering systolic blood pressure and improving vascular function in otherwise healthy or normotensive adults (Siervo et al., 2013; Lara et al., 2016). In addition, beetroot’s betalains and phenolic compounds exhibit strong radical-scavenging and antioxidant effects in human and preclinical studies, contributing to protection against oxidative stress and exercise-induced muscle damage, which may support recovery and overall cardiovascular resilience (Hadipour et al., 2020; Razzak et al., 2024).*

Dietary nitrate from beetroot and other vegetables provides additional support for nitric oxide production, helping blood vessels widen and muscles work more efficiently during exercise. Jones et al. report that amounts comparable to a concentrated beetroot shot or a large serving of high‑nitrate vegetables can reduce the oxygen cost of exercise and, at suitable doses, enhance endurance performance. Figure 4 shows that several days of dietary nitrate (NO3−) supplementation may enhance the performance of healthy, recreationally active individuals during activities that require the generation of power and speed over short distances and durations. This phenomenon is likely explained by favorable changes in muscle contractility.*
