Beetroot juice nitrate content varies by up to 10x between bottles. Why? Soil quality. Harvest season. Storage conditions. Processing method. Even two bottles from the same brand can deliver completely different nitrate loads.

For an athlete, that's a problem. If you're timing your dose to peak at the start gun, you need to know exactly what's in your system. With juice, you're guessing.

Stamox is standardised. Every scoop. Every tub. Same dose. Same result.

Most commercial beetroot juices are processed for taste and shelf stability. That process strips out betaine and betalains — two compounds critical to the full performance effect.

• Betaine sustains power output deep into efforts. It pulls water into muscle cells, helping you hold threshold wattage when others fade.
• Betalains are beetroot's unique antioxidants. They clear metabolic waste and reduce inflammation. Recovery begins before the session ends.

A 2024 meta-analysis by Sánchez-Oliver et al. confirmed: whole beetroot outperforms isolated nitrate for both endurance and recovery. The matrix matters. Removing compounds reduces the effect.

Beetroot juice is high in fermentable sugars. For many athletes, that means bloating, stomach cramps, and GI distress — especially during hard efforts or in the heat.

Stamox is a powder. Lighter. Cleaner. Mixes with water. No sugar load. No stomach issues. The same performance benefit, without the digestive risk.

Beetroot is one of only five supplements with the highest evidence rating from the International Olympic Committee — alongside caffeine and creatine.

But that rating applies to standardised, dosed beetroot supplementation. Not to variable juice off a supermarket shelf. The classification assumes you know what you're taking.
