How Stamox Works

Stamox optimises how your body uses oxygen at the cellular level. Effects peak 2–3 hours after consuming.

Documented Performance Benefits

Athlete wearing VO2 Master mask during intense endurance training, boosting performance and recovery.

Oxygen Efficiency

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

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

Athlete sprinting with motion blur, showcasing endurance and power for athletic performance.

Endurance

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

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

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

Cyclist in aerodynamic helmet and performance jersey, coastal backdrop, endurance training focus

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.
