Beets / Beetroot for Energy And Fatigue

Research suggests that beetroot juice, which is rich in dietary nitrate and raises nitric oxide levels in the body, may support physical energy output and reduce muscular fatigue, particularly during high-intensity and repeated-effort exercise. The available evidence — drawn from a 2018 systematic review of nine studies, a randomized controlled trial, and a mixed-methods study — generally points toward benefits such as faster oxygen uptake during hard efforts, extended exercise endurance, and improved phosphocreatine resynthesis between bursts of activity. Studies indicate these effects may be most pronounced during intense exercise that heavily recruits fast-twitch muscle fibers, though the precise mechanisms are not yet fully understood. It is worth noting that at least one study found no improvement in cognitive performance or mental fatigue alongside the physical benefits, suggesting the effects of beetroot juice may be more specific to physical exertion than to overall energy or alertness.
