Evidence Level
Strong
Beet root supplementation has strong clinical evidence, particularly for cardiovascular and exercise outcomes. Siervo et al. (2013) conducted a systematic review and meta-analysis demonstrating significant blood pressure reduction with beetroot juice supplementation. Dominguez et al. (2017) confirmed cardiorespiratory endurance improvements in athletes, with beetroot juice extending time to exhaustion by 3-5%. A 2018 systematic review by Bonilla Ocampo et al. reinforced these findings, concluding that dietary nitrate from beetroot juice is an effective non-pharmacological strategy for hypertension management.
