Is Beetroot Nitrate Exercise Performance Meta-Analysis safe?

The current Migaku evidence database contains 2 reusable source documents for Beetroot Nitrate Exercise Performance Meta-Analysis. This answer focuses on safety, limits, and clinician-discussion contexts. - Results Salivary concentrations of NO 3 - and nitrite NO 2 - were also measured and in comparison to the placebo drink, the intake of beetroot juice increased salivary concentrations of NO 3 - (from 230 ± 435 vs 6164 ± 3370 μM; p = 2 - (130 ± 131 vs 4509 ± 4895 μM; p = 0.018; ES = 1.63). [López-Samanes Á (2026); evidence level 2] - Conclusion Acute ingestion of 70 mL beetroot juice containing 6.4 mmol of NO 3 - did not enhance sprint performance or the neuromuscular function of male trained sprinters.Trial registration: The study was retrospectively registered in ClinicalTrials.gov with the following ID: 5-56NCT06675682 by 1 November 2024. [López-Samanes Á (2026); evidence level 2] - Introduction The aim of this study was to evaluate the acute effect of beetroot juice ingestion on sprint performance and neuromuscular properties of male trained sprinters. [López-Samanes Á (2026); evidence level 2] - Methods Twelve male sprinters (24.3 ± 4.8 years) participated in a randomized, double-blind, and placebo-controlled study with two experimental trials after the ingestion of 70 mL beetroot juice (containing 6.4 mmol NO 3 -) or 70 mL placebo drink (containing 0.04 mmol NO 3 -). [López-Samanes Á (2026); evidence level 2] - Although dietary nitrates were historically approached with caution due to concerns about nitrosamine formation, contemporary evidence highlights their beneficial effects on vascular, metabolic and cognitive functions. [Kurhaluk N (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
