Journal of the International Society of Sports Nutrition (2025) · Meta analysis · n=422
This revision included 23 studies, 16 of them (69.6%) qualified as excellent and 7 (30.4%) as good at the methodological level based on the punctuation in the PEDro scale.
The points come from one crossover dose-response trial in 10 healthy men given 70, 140 or 280 mL of concentrated beetroot juice, containing 4.2, 8.4 and 16.8 mmol of nitrate (about 260, 521 and 1,042 mg), 2.5 hours before cycling (PMID 23640589). 70 mL did not change the exercise responses compared with nitrate-depleted placebo. 140 and 280 mL extended time to task failure in severe cycling by 14% and 12%, and the higher dose gave no further improvement, so the curve is flat above 521 mg. The abstract does not report tolerability, so no ceiling is set. The curve rests on acute single doses in young men and cannot show effects of daily use, in women, in older adults or in trained athletes.
