Summary

This study investigates whether a beetroot powder jelly candy can help competitive swimmers swim faster and feel less tired. Beetroot is rich in nitrate, which the body converts to nitric oxide, a compound that may improve blood flow and muscle efficiency. The trial involves 21 swimmers aged 18-24 who will take either the beetroot candy or a placebo and then complete a 200-meter freestyle swim to compare times and fatigue levels.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
beetroot powder
What this could lead to
If effective, beetroot powder could offer a natural, safe way for swimmers to improve performance and reduce fatigue without drugs.
What could go wrong
This is a small, early-stage trial with only 21 participants. Results may not apply to all swimmers, and the effect may be too small to matter in competition.
