Our Story

Smiling man outdoors with Utrecht University and University of Applied Sciences Upper Austria logos, stamox beetroot powder

Dr. Nils Reither, DVM Utrecht, 1990 · 36 years in industry

In 2007, Dr. Reither created the foundational Stamox matrix. Since then, it has been validated by 19 years of elite use, ongoing R&D with the University of Applied Sciences Upper Austria, and independent anti‑doping testing.

From Norway, for human performance.

How It Works

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

Standardised. Measurable. No guesswork.

Standardised. Measurable. No guesswork.

Unlike ordinary beetroot juice, Stamox delivers a standardised, measurable dose of the full beetroot matrix – nitrates, betaine, and betalains. Every scoop is consistent, so your training results are predictable. No fluid overload. No guesswork.

Beetroot is one of only five supplements with IOC Level A and AIS Group A classification – the highest evidence tier in sport, alongside caffeine and creatine.

How to Use

04 / Critical Constraint

Avoid mouthwash, tongue scraping, and breath mints — they kill the bacteria that convert nitrates into nitric oxide.

FAQ

Pure red beetroot extract (Beta Vulgaris) and a trace amount of maltodextrin strictly as a technical anti-caking agent.

This is to prevent our highly concentrated active powder from absorbing airborne moisture and turning into a solid block. Stamox contains zero artificial fillers, zero sweeteners, and is anti-doping tested.

Stamox has a slightly sweet and earthy flavour.

If you want to mask the natural earthy undertones, mix Stamox with citrus juice (like lemon or orange) or blend it into your favorite fruit smoothie.

You can easily mix Stamox with water, in juice, in a smoothie or in youghurt.

For the smoothest mix, pour your water into the glass first, add the powder, let it sit for 2 minutes, and then stir (or use a handheld frother).

It sounds strange, but the magic actually starts on your tongue! The natural conversion of dietary nitrates into nitric oxide relies heavily on the beneficial bacteria in your mouth. Using antibacterial mouthwash or aggressive spitting within 30 minutes of taking Stamox can kill these bacteria, drastically reducing the supplement's effectiveness.

Yes, consistent daily use triggers permanent structural upgrades.

While a pre-workout dose provides immediate oxygen efficiency, daily dosing over 3+ weeks promotes mitochondrial biogenesis—meaning your body structurally builds brand-new cellular power plants to increase long-term training capacity.

The nitrate content in Stamox ranges from 1.3% to 1.7%, averaging 1.5% with a +/- 0.2% variance.

That means you're getting around 300 mg of nitrate in just two tablespoons.

However, it's crucial to understand that nitrate is only one component contributing to Stamox's unique benefits. You won't get the same results by simply taking nitrates on their own.

The true power of Stamox comes from the synergistic blend of nitrates, antioxidants and its other natural compounds working together.

  • Premium Beetroot: Sourced from the highest quality red beetroot.
  • Patented & Potent: A unique extraction ensures a stable, reliable strength in every batch.
  • Nutrient-Preserving: Processed to lock in essential micronutrients.
  • Pleasant & Versatile: A fine powder with a fresh taste for easy dosing.

Do not panic! This is a completely harmless condition called beeturia. It happens because Stamox is highly concentrated and rich in betalains—the vibrant, natural pigments found in beetroot that give it its powerful antioxidant properties. It is temporarily passing through your system and is 100% safe.
