Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Beetroot (Beta vulgaris) has garnered scientific interest for its potential to combat fatigue, mainly due to its high content of dietary nitrates. When consumed, these nitrates are converted in the body to nitric oxide, which can enhance blood flow, improve oxygen delivery to muscles, and thereby potentially reduce perceived exertion during physical activity. Several clinical trials have demonstrated that beetroot juice supplementation can improve exercise performance and stamina, particularly in athletes and older adults. For instance, studies published in journals such as Journal of Applied Physiology and Physiology & Behavior have found that beetroot supplementation can increase time to exhaustion during submaximal exercise, suggesting a reduction in fatigue. However, the majority of these studies focus on exercise-induced fatigue rather than chronic fatigue conditions or general tiredness. Evidence for beetroot’s efficacy in treating fatigue associated with medical conditions (such as chronic fatigue syndrome or cancer-related fatigue) is currently lacking or inconclusive. While the physiological rationale for improved oxygen utilization is strong, and the benefits for athletic performance are modest but consistent, the direct application to broad fatigue symptoms in the general population is less established. In summary, while there is emerging scientific support—mainly in the context of exercise-induced fatigue—the evidence is not robust enough to warrant a high rating for general fatigue treatment.
