THE SCIENCE

One of the most studied
ingredients in sport.

"Dietary nitrate reduces the O₂ cost of exercise and extends time-to-exhaustion by up to 25%." Prof. Andrew Jones, University of Exeter (Jones et al., 2013)
20 meta-analyses · 180 studies · 2,672 participants

The 2025 umbrella review found improvements across time-to-exhaustion, distance, muscular endurance, and peak power.

Across sports

Benefits shown in cycling, running, rowing, and triathlon — from 5K to marathon.

Oxygen Efficiency

4–5% reduction in oxygen cost of submaximal exercise.

Nitric oxide improves mitochondrial efficiency. ATP production increases per unit of oxygen consumed.

Endurance

15–25% improvement in time-to-exhaustion.

Reduced oxygen cost delays the onset of fatigue. Sustained vasodilation maintains muscle oxygenation.

Domínguez et al. (2017),Nutrients; IOC Consensus (2018).

Power Output

2–5% increase in endurance power output. Athletes report up to 15% in key sessions.

Enhanced oxygen delivery supports sustained wattage at threshold. Betaine contributes to cellular hydration.

Peak Sprint Power

Up to ~11% gain in peak power during repeated sprint efforts.

Nitrate supplementation enhances type II (fast-twitch) muscle fibre contractility.

Blood Pressure

4–10 mmHg systolic reduction within 2–3 hours of a single dose. Sustained reductions of 8–10 mmHg with daily use over 2–6 weeks.

NO-mediated vasodilation reduces peripheral vascular resistance. Endothelial function improves chronically.

Cognitive Function

Improved reaction time and decision-making accuracy under fatigue.

Increased cerebral blood flow to the prefrontal cortex. NO-mediated vasodilation is not limited to skeletal muscle.

Three Major Areas of Research

Sports Performance

The most researched area. Dietary nitrates reduce the oxygen cost of exercise by 3–5%. Time-to-exhaustion improves by 15–25%. Power output increases by 2–5%. Studies span cycling, running, rowing, and team sports. The IOC Level A classification is based on this body of evidence.

Cardiovascular Health

Clinically meaningful. Blood pressure drops 4–10 mmHg within hours of a single dose. Sustained reductions of 8–10 mmHg systolic with daily use over 2–6 weeks. Nitric oxide relaxes blood vessels. Peripheral resistance drops. Arteries become more flexible over time.

Cognitive Function

An emerging field. Nitric oxide increases blood flow to the prefrontal cortex — the brain region responsible for decision-making and reaction time. Early data shows improved reaction speed and accuracy during prolonged exercise. Relevant for athletes making split-second decisions under fatigue.
