New Study Confirms Beetroot-Nitrate Supplementation Improves Endurance, Oxygen Efficiency, and Sprint Power 

A major new scientific review published on PubMed (PMID: 40085422) provides strong, evidence-backed support for dietary nitrate supplementation as an effective and natural performance enhancer. Here’s exactly what the latest science says—and why it matters for athletes and fitness enthusiasts alike.

Key Scientific Findings

The comprehensive umbrella review, led by researchers Eric Tsz-Chun Poon, Jason Chun-Kit Iu, Wesley Man-Kuk Sum, and colleagues, analysed 20 systematic reviews covering 180 individual studies with over 2,600 participants. The results strongly reinforce dietary nitrates—particularly from beetroot—as credible ergogenic aids:

✔ Boosts endurance performance by 4–6%
✔ Improves oxygen efficiency by 5%
✔ Enhances sprint power by up to 5%
✔ Greater benefits for recreational athletes (up to 7%)
✔ Safe, natural, with no major side effects reported

These findings echo the authoritative conclusions from the International Olympic Committee (IOC) Consensus Statement (2018), which identified dietary nitrate—especially beetroot juice—as one of the few supplements scientifically proven to improve athletic performance by:

✔ Reducing the oxygen cost of submaximal exercise (~3–5%)
✔ Improving performance times (~1–3%) in timed events
✔ Increasing time-to-exhaustion performance by up to 25%

This latest review adds even more robust evidence supporting nitrate supplementation for performance optimisation.

Why This Matters for Your Performance

For athletes and fitness enthusiasts already using beetroot supplements for endurance events, marathons, cycling races, or intensive training sessions, these findings provide clear validation for nitrate dosing to:

✅ Naturally enhance your endurance and go further, faster
✅ Improve sprinting power when every second counts
✅ Optimise oxygen efficiency, allowing your muscles to perform better and fatigue slower
✅ See measurable performance benefits whether you’re elite or recreational

The reassurance of no significant side effects across extensive research makes beetroot-derived nitrate a uniquely reliable, natural choice.

Optimal Dosing – Beet It Sport Makes it Simple

The review also clarified an important practical detail: effective nitrate supplementation requires a minimum dose of 6 mmol (~370mg nitrate)—with stronger benefits from consistent use over three or more days.

Each Beet It Sport Nitrate 400 Shot contains a scientifically precise dose of 6.4 mmol (400mg nitrate)—meeting and surpassing this clinical standard.
