FAQ

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.

Regular beetroot juice varies enormously in strength — one bottle may work, the next may not. Most products are not tested or standardised, so dosing is guesswork. Stamox delivers a consistent, measured dose every scoop — with the full beetroot matrix intact (nitrates, betaine, betalains). Trusted by elite athletes for 19 years.

Stamox naturally has a sweet and earthy taste. Unflavoured and can easily be mixed into water, smoothies, or a pre-workout.

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.

Mix 1-2 tablespoons into 500ml of cold water, juice, or your pre-workout 2–3 hours before training or racing. Skip mouthwash and breath mints for at least 2 hours after taking Stamox, as mouthwash kills the oral bacteria required to convert dietary nitrates into nitric oxide.
