THE PHYSIOLOGY

The Nitrate-Nitrite-Nitric Oxide Pathway

Endurance performance is limited by oxygen efficiency. Here is exactly how dietary nitrate interacts with your body to support blood flow and oxygen delivery.

01 / INGEST

Nitrate

You consume dietary nitrate. Bacteria naturally present on your tongue begin converting it into nitrite.

02 / CONVERT

Nitrite

Nitrite enters the bloodstream and is converted into nitric oxide (NO), a critical signaling molecule.

03 / PEAK

Nitric Oxide

NO relaxes blood vessels, supporting blood flow to working muscle. Peak plasma nitrite occurs 2–3 hours after ingestion.

Why the whole root matters: Isolated salts lack the synergistic matrix required for this process. Whole-root beetroot delivers nitrates alongside betaine, betalains, and polyphenols—which is why the clinical data shows it works, while synthetic pills fail.

3–5% Lower O₂ Cost

Your muscles extract oxygen more efficiently. The same wattage feels easier. Peak plasma nitrite occurs 2–3 hours after intake.

4–25% Longer Time-to-Exhaustion

Nitric oxide widens blood vessels, improving blood flow. You hold your target pace deeper into the session before fatigue sets in.

Supports Normal Blood Pressure

Dietary nitrates contribute to the maintenance of normal blood pressure by supporting natural nitric oxide production and vasodilation.

Faster Recovery (72h)

Betalains and polyphenols reduce oxidative stress and inflammation, accelerating isometric strength recovery and reducing muscle soreness.

FAQ

No. Unlike raw beetroot or high-fiber juice, Stamox is a pure, whole-root extract designed to be gentle on the stomach.

Regular juice varies wildly by batch and is often high in sugar. Stamox is a patented whole-root extract that preserves the full matrix of active compounds without the sugar or fluid load.

Yes. Stamox undergoes rigorous testing by the Anti-Doping Laboratory in Cambridge.

They confirm it is 100% free from prohibited substances and natural contaminants. We regularly submit batch samples and can provide certification documents upon request.

Two tablespoons of Stamox deliver approximately 300 mg of natural dietary nitrate (our extract averages a highly consistent 1.5% nitrate content).

Taking isolated, synthetic nitrates won't give you the same performance boost. The real power of Stamox is the synergy. You are getting that precise nitrate dose working together with the plant's natural antioxidants, betalains, and betaine. That full-spectrum matrix is what actually drives the lower heart rate and faster recovery.

Premium red beetroot extract (Beta vulgaris) with a maltodextrin carrier.

Slightly earthy, naturally sweet. Mix with cold water and lemon. No GI distress.

Mix 1 tablespoon into 500ml water, juice, or your pre-workout. For the smoothest mix: liquid first, then powder, wait 2 minutes, stir (or use a frother). Add a splash of lemon or orange to brighten the taste. Also great in smoothies or yoghurt.
