Regular beetroot juice is not defined or tested for strength. One bottle may work. The next may not. Nitrate content varies by soil, season, and harvest — you cannot plan training around guesswork.
Stamox delivers the full beetroot profile — nitrates, betaine, betalains. Standardised dose. Consistent effect. Every scoop.
Created by Dr. Nils Reither in 2007. Proven through elite athlete use and independent testing.
Stamox preserves muscle oxygenation.

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.
