The science of endurance performance has found an unlikely ally: beetroot.
Endurance athletes understand that marginal improvements add up to significant results. Every stride, pedal stroke, and repetition contributes to the final outcome, which is why the research on beetroot's performance benefits has caught the attention of serious athletes and sports scientists alike.
The key lies in dietary nitrates, compounds that the body converts into nitric oxide, directly impacting oxygen utilization and blood flow during exercise. The research consistently shows that 400mg of nitrates can measurably improve endurance capacity, reduce the oxygen cost of exercise, and delay the onset of fatigue.
Blonyx has partnered with Beet It Sport to deliver these benefits in concentrated form. Beetroot as a proven performance tool that delivers specific, measurable benefits when consumed at research-backed dosages.
Read the science behind beet juice and diatary nitrates.
The Advantage of Nitrates for Endurance Performance
At the core of beet juice's endurance benefits are dietary nitrates. Once consumed, these nitrates convert into nitric oxide (NO) in your body. Nitric oxide is a powerful vasodilator, meaning it helps widen your blood vessels. This improved blood flow allows for more efficient delivery of oxygen and nutrients to your working muscles, while simultaneously reducing the oxygen cost of exercise. In simple terms? Your body uses less energy to perform the same amount of work, delaying fatigue and extending your endurance capacity.

Improved Oxygen Efficiency
Your muscles work harder with less oxygen, making every breath count.

Enhanced Blood Flow
Better delivery of vital nutrients and removal of waste products.

Reduced Fatigue
Delay the onset of exhaustion, allowing you to sustain higher intensities for longer.

Increased Time to Exhaustion
Push past previous limits and extend your endurance performance.
Why 400mg of Nitrates is the Optional Dose
Research consistently points to a sweet spot for nitrate intake to elicit significant endurance benefits: 400mg of dietary nitrate. This isn't just an arbitrary number; it's the amount shown in numerous scientific studies to reliably produce performance improvements in athletes. While you could eat many beets to reach this, the concentration in specialized beet juice shots makes it easy and effective. This 'nitrate rule' ensures you get the optimal dose without guesswork, maximizing your body's ability to convert nitrates into performance-boosting nitric oxide.
Blonyx's Beet It Sport Collection
We partner with Beet It Sport, a brand renowned for its consistent, precisely dosed nitrate content, ensuring you always get the scientifically effective 400mg when you need it most. Our collection is engineered to fuel your most demanding endurance challenges.
Timing is Key: When to Take Your Nitrates

Pre-Event or Workout
For optimal results, consume one Beet It Sport Nitrate 400 shot 2–3 hours before your race or most intense training session. This allows sufficient time for nitrate conversion to nitric oxide.

Loading Phase (Optional)
For multi-day events or consistently high performance, some athletes benefit from a "loading phase," consuming one shot daily for 3-7 days leading up to a major event.

During Long Efforts
Use the Beet It Sport Top Up 100 Energy Gel for sustained energy and nitrate benefits during longer training sessions or races.
