Dr. Nils P. Reither

Stamox Beetroot Extract Powder was developed in Norway since 2007 by Dr. Nils Reither, DVM (Utrecht, 1990) and colleagues. Years of extensive research and peer-reviewed studies have been conducted on the benefits of beetroot powder: showing outstanding results for health conscious individuals, sports enthusiasts and high performing athletes. Stamox has now been on the market for over 17 years and is used by world-class athletes, coaches and chiropractor around the world.

Science

Stamox increases lung capacity, blood flow and oxygen efficiency. Stamox helps your body make the most of the oxygen you breathe, turning it into more usable energy for your exercise.

Stamox's high concentration of natural dietary nitrates (NO3) converts into nitric oxide (NO), a molecule that promotes vasodilation-widening blood vessels to improve oxygen-rich blood flow to muscles and organs.

For athletes, drinking Stamox 2-3 hours before training or competition can result in:

  1. More efficient ATP production (4-5% oxygen efficiency improvement).
  2. 2-5% increase in power output, translating to 5-15 watts more sustained power.
  3. Delayed muscle fatigue, improving overall endurance performance.
" "

Timing

For optimal results, consume Stamox about 60 to 90 minutes before the event or a workout because its effect peak within 2 to 3 hours after consumption. Stamox gives your body the nutrients needed to open up the blood vessels, making everything run more smoothly, especially during exercise.

Nitrate, Antioxidants & Natural Compounds

Rich in dietary nitrates, antioxidants and other nutrients, Stamox enhances the body's nitric oxide (NO) production; leading to improved blood flow, oxygen efficiency, and reduced fatigue. The true power of Stamox comes from the synergistic blend of nitrates, antioxidants and its other natural compounds are working together.

Potential ATP & Power Output Increase

1. ATP Production Efficiency

  • Stamox improves mitochondrial efficiency, reducing the oxygen cost of exercise by 4-5%.
  • This means the muscles generate more ATP per unit of oxygen, enhancing endurance and sustained power output.

2. Power Output (Wattage) Increase

  • Studies show an increase of 2-5% in power output during endurance exercise.
  • This equates to an increase of 5-15 watts in trained cyclists and runners.
  • Sprint performance may also improve slightly (1-3% gain).

3. Muscle Oxygenation & Performance

  • Improved muscle oxygenation leads to delayed fatigue onset and sustained ATP production.
  • VO₂ max (maximum oxygen uptake) efficiency improves, leading to longer time-to-exhaustion

Key Independent Research & Reviews

While Stamox itself is a specific brand, the active compound—inorganic nitrate (NO3−)—has been exhaustively studied by universities and sports organizations worldwide. These studies are not sponsored by Stamox and represent the scientific consensus on nitrate supplementation:

IOC Consensus Statement (2018)

Focus: Overall Athlete Supplementation

Key Findings

Categorizes dietary nitrates as one of the few supplements with "Level A" evidence for performance enhancement.

Jones (2014) - Sports Medicine

Focus: Mechanism & Performance

Key Findings

A foundational review explaining how nitrates reduce the "oxygen cost" of exercise, making muscles more efficient.

Pawlak-Chaouch et al. (2019)

Focus: Meta-Analysis on VO2 Max

Key Findings

Confirmed that nitrate supplementation significantly improves time-to-exhaustion and endurance in sub-maximal exercise.

Wylie et al. (2013)

Dose-Response Relationship

Key Findings

Independent trial showing that the effects are dose-dependent, peaking about 2–3 hours after ingestion.

Thousands of peer-reviewed studies

To give you an idea of the scale: a search on PubMed (the gold-standard database for biomedical research) for "beetroot" or "dietary nitrate" returns thousands of peer-reviewed studies.

Because of the volume of research, the International Olympic Committee (IOC) officially categorized beetroot/nitrates as a "Level A" supplement. This means there is high-quality, consistent evidence that it actually works. It sits in the same elite category as caffeine and creatine.

Major Areas of Research

The research is generally split into three "buckets"
(The most researched area)

1. Sports Performance

Exercise Economy: Studies consistently show that nitrates allow muscles to perform the same amount of work while using less oxygen (O2)

Time to Exhaustion: Massive amounts of data on cyclists, runners, and rowers show an average improvement of 15–25% in time to exhaustion during high-intensity intervals.

Muscle Power: Recent research (2020–2025) has focused on "sprint" and "explosive" power, showing that nitrates help fast-twitch muscle fibers contract more forcefully.

2. Cardiovascular Health

Blood Pressure: Extensive clinical trials confirm that 250ml of beetroot juice (or an equivalent dose) can lower systolic blood pressure by 4–10 mmHg within hours.

Vascular Aging: Research shows it helps "stiff" arteries become more flexible, which is a major area of study for heart disease prevention.

3. Cognitive Function

Brain Blood Flow: Emerging research (though less conclusive than the sports data) suggests that the increased nitric oxide improves blood flow to the prefrontal cortex, potentially helping with reaction time and decision-making under fatigue.
