Stamox optimises how your body uses oxygen at the cellular level. Effects peak 2–3 hours after consuming.
Dietary nitrates convert to nitric oxide. Blood vessels relax.
Vasodilation peaks. Oxygenated blood reaches working muscles.
You hold target wattage while burning less oxygen.
Betalains clear metabolic waste.
Consistent use supports mitochondrial efficiency.

Backed By 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 16%." — Prof. Andrew Jones, University of Exeter (Bailey et al., 2009)
IOC Consensus: Strong Evidence
Dietary nitrates (beetroot) are one of only five supplements classified as having strong performance evidence by the International Olympic Committee — alongside caffeine and creatine.
19 Years R&D
Formulated in Norway. Refined since 2007. Anti-doping tested.
Mix 1 tablespoon into 500 ml water. Drink 2–3 hours before training.
New to beetroot? Start with half a dose to assess tolerance.
02 / Racing Protocol
Use 2–3 tablespoons for hard sessions or race day. Same 2–3 hour window.
03 / Versatile Mix
Mix with water, juice, smoothies, or your pre-workout stack. Add a splash of citrus (lemon or orange) to brighten the flavour and improve absorption. Chilling with ice also helps.
Stamox is significantly lighter and easier to mix than raw beetroot juice — no strong earthy aftertaste.
04 / Critical Constraint
Skip mouthwash, tongue scraping, and breath mints after taking Stamox — they reduce nitrate conversion.
Raw Data & Case Studies
*Individual results vary. Performance gains depend on training status, baseline nitrate levels, dosage timing, and consistency of use. Effects develop over weeks, not days.
Lower RPE & Heart Rate
Marco V. held identical power at a lower heart rate.
"I’ve found the missing link in my running with Stamox. The data doesn’t lie: 166 bpm on 3:03/km reps."
Sophie Souwer
x2 World Champion, x2 Olympian, x3 European Champion
"Lactate threshold from 82% to 88%. I can push harder for longer."
Hamza Saeed
Performance Coach
"The best product I've ever tried. A game-changer for athletes with sensitive digestion. Elite performance benefits while keeping my GI happy."
MarcoValerio Ciminelli
Italian Cyclist
"I've used other beetroot powders, but Stamox is significantly better. It mixes easily, has a lighter taste, and is vastly easier on the stomach pre-workout."
Thijs Vercaemer
Marathon Runner
"It mixes much better than other powders... and it doesn't affect my stomach or intestines like other competitor brands did."
Shannon Troup
Hydrox Athlete, IMMAF MEDALIST and IFMA MEDALIST
"Taste is great. Better than beetroot shots."
Maciek Maślanko
Polish Champion & World Championship Medalist
"The predictable effect — peak performance 2–3 hours after taking it — lets me plan every session with precision."

Dr. Nils Reither
Created by Dr. Nils Reither in 2007. Proven through elite athlete use and independent testing.
Stamox is engineered for data-driven endurance athletes (cyclists, runners, triathletes, rowers) aiming to improve VO₂ max, lactate threshold, and O₂ economy.
Most users notice improved endurance, lower perceived effort, and faster recovery rather than a sudden jump in peak power. Effects are most pronounced during sustained efforts, not short sprints.
Trained and recreational athletes typically see the largest relative gains. Elite athletes with already-optimised oxygen efficiency may see smaller but still meaningful improvements — often 1–2% — which can be race-defining at the top level.
Stamox is not a stimulant-based pre-workout. If you are looking for a quick caffeine buzz or a generic gym "pump," this product is not for you.
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.
Raw beetroot powders contain fibers and oxalates that cause stomach issues during hard efforts. Stamox is a highly refined extract—we isolate the active matrix and remove the fibrous compounds for maximum tolerability. However, as with any sports nutrition, we always recommend testing your dosing protocol in training before using it on race day.
Premium red beetroot extract (Beta vulgaris) with a maltodextrin carrier.
Stamox delivers a full-spectrum matrix: naturally occurring nitrates (oxygen delivery), betaine (power output), and betalains (recovery). Zero stimulants. Zero banned substances.
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.
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 and boost absorption. Also great in smoothies or yoghurt.
Yes. Stamox is 100% non-stimulant. It lowers the oxygen cost of exercise by optimizing vascular nitric oxide and mitochondrial efficiency—not by artificially stimulating your central nervous system. You get full threshold power benefits without disrupting your sleep or recovery metrics.
Mouthwash kills the oral bacteria that convert dietary nitrates intonitric oxide. Skip mouthwash, tongue scraping, and breath mints for atleast 2 hours after taking Stamox — or you'll blunt the effect.
Yes. Dietary nitrates relax blood vessels — the same mechanism that improves oxygen delivery to working muscles. This supports healthy blood pressure. If you have low blood pressure or take blood pressure medication, monitor your response and consult your doctor. Start with half a dose.
In some people, yes. Beetroot contains natural pigments called betalains that can temporarily colour urine or stool pink or red. This is completely harmless and not blood — it simply means your body is processing the beetroot. If it happens, it disappears within 24–48 hours after stopping use.
Stamox is anti-doping tested and suitable for most athletes. If you have a history of kidney stones (beetroot contains oxalates), are pregnant, or take medication, consult your healthcare provider before use.
