Beetroot boost: does more nitrate mean more endurance?

NCT ID NCT07735455

First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time

Summary

This pilot study explores whether a single dose of dietary nitrate, a natural compound found in beetroot and leafy greens, can improve running endurance and reduce muscle fatigue. Recreationally active men will take either a placebo or one of three nitrate doses before a treadmill test to exhaustion. The goal is to see if higher doses lead to greater benefits.
