Benefits of Beetroot / Dietary Nitrate

Evidence-Based Benefits

• Endurance performance — a meta-analysis (McMahon et al., 2017) of 76 studies found dietary nitrate supplementation significantly improved time to exhaustion and time trial performance, particularly in recreationally active individuals
• Oxygen efficiency — Bailey et al. (2009) demonstrated beetroot juice reduced oxygen cost of moderate-intensity exercise by 5% and extended time to exhaustion by 16%, effectively improving exercise economy
• Blood pressure — Siervo et al. (2013) meta-analysis found inorganic nitrate and beetroot juice reduced systolic blood pressure by 3-10 mmHg, comparable to some antihypertensive drugs
• High-altitude and hypoxic performance — the nitrate-nitrite-NO pathway becomes more active under hypoxic conditions, making beetroot particularly effective at altitude

What the Research Says

Beetroot juice is one of the most thoroughly studied ergogenic aids in endurance sports. The nitrate-nitrite-NO pathway provides an oxygen-independent route to nitric oxide production that complements the classical L-arginine pathway. Research consistently shows beetroot reduces the O2 cost of exercise and improves endurance performance by 1-3%. Notably, effects are more pronounced in recreational athletes than elite athletes, possibly because elite athletes already have optimized NO production. The blood pressure benefits add a significant health dimension beyond athletic performance.
