Natural dietary nitrates relax blood vessels → Supports healthy blood pressure and vascular flow.

ANTIOXIDANT DEFENSE
Rich in beetroot pigments (Betalains) → Fights oxidative stress and supports a healthy inflammatory response.

CLEAN, SUSTAINED ENERGY
Optimises cellular oxygen use without stimulants → Steady focus and daily productivity with zero jitters or crashes.

BRAIN & IMMUNE SUPPORT
Increases nutrient delivery to cells → Sharper mental clarity and reinforced immune resilience.

Timing: Drink 2-3 hours before your training session or race. This allows the nitrate-to-nitric oxide conversion to hit its peak.

Daily Training: 1-2 tablespoons.

Before a Race/Competition: 2-3 tablespoons.

For Daily Health: Mix a teaspoon up-to 1 tablespoon.

Endurance Race: For longer sessions (more than 1 hour), you can take an additional 1 tablespoon of Stamox closer to the start of the training session.

Pro Tip: Avoid using mouth wash and spitting after taking Stamox as it kills oral bacteria needed to convert nitrates.

Stamox Loading: To maximise the benefits before a race or significant training block, research suggests a loading phase by taking a competition dose of Stamox daily for 3-7 days leading up to the event.

Mixing Tip: Add the powder to the water and let it sit for 2–3 minutes, then stir. Also mixes well with a frother or a blender.

You would have to drink a lot of "regular" beetroot juice to achieve a good effect, and the amount you need to drink will vary enormously.

There are many types of beetroot juice available for purchase. But the "strength" of these is not further described, defined and tested. You can use beetroot or beetroot juice, but the effect will be unpredictable and usually less effective, or have zero effect. It is simply not possible to create a predictable training program with regular beetroot juice.
High Demand Notice: Due to the high volume of orders, there is a slight shipping delay in delivery within the EU.

How does Stamox work?

I’ve noticed a massive boost in my performance with Stamox. It used to take me a while to find my rhythm, but now my body feels fluid and ready. Before I started using Stamox, my morning sessions were always a struggle. Stamox has been a game-changer for avoiding that early morning caffeine crash.

I just want to say how much I’ve enjoyed using Stamox these last 6 weeks. I re-tested my 12min max and saw a 2.6% increase from 448 to 460 which is a serious performance jump. I also use it in my recovery shakes to accommodate Excess Post-exercise Oxygen Consumption.

Stamox has been a game changer. Tests show that Stamox can increase both my VO2 max durations and endurance durations. I personally think Stamox is the most interesting supplement to consider when trying to boost endurance performance. Not just because of its evidence, but also because of its good taste and the variety of options to take it.
Roger Pedersen

Bodybuilder, used Stamox for over a decade

"10/10 in rating if you want a product that is natural that WORKS!! After trying Stamox 10 years ago, I never looked back. I always have that little extra to give when I do cardio. And when I train weights? The body recovers much faster between sets and reps, and I can increase up to 2 to 4 reps if I train for hypertrophy."

FAQ

Stamox has a slightly sweet and earthy flavour, just as nature intended it to be. There are no added flavours or sweeteners.

It has a versatile flavour that can be mixed with water, citrus (will hide the beetroot taste), yoghourt, oats, smoothies, in electrolytes, carb drink, etc.

"I've used beetroot powder from another supplement company before but Stamox is significantly better as it is has better solubility and lighter taste and consistency. The other company's product is heavier in texture and taste and also harder to digest. In fact, they contain a higher fiber content (which is harmful pre-workout)." Says Italian cyclist Marco Valerio Ciminelli

Per tub has 200 grams powder. A standard training dose is 1 tablespoon (around 10g) and health dose is 5 grams (teaspoon).

Serving Size per tub:

  • 40 servings (health dose)= €0.90 per day
  • 20 servings (training dose) = €1.80 per session

Tub Colour Variation: Black or White tub.

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.

This is a critical biological step. The "Nitrate-Nitrite-NO" pathway relies on commensal bacteria on the back of your tongue to convert nitrate into nitrite. Antibacterial mouthwash kills these bacteria, effectively "breaking" the chain and preventing the performance benefits.

Stamox is a pure extract of beetroots made only from the highest quality beetroot (Beta Vulgaris). A small % maltodextrin is added as a anti caking agent.

  • 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.

You can add Stamox in water, porridge, smoothies, yogurt, or protein shakes.

When blending with water, don’t pour all the water in at once. Start with the powder in the glass and add just a tiny splash of water. Stir vigorously with a spoon until it forms a thick, smooth paste. Then, gradually add the rest of the water while stirring.

Use a Frother: If you have a small handheld battery milk frother, it can help breaks up those seasonal lumps in seconds.
