Can a spoonful of agave fiber rewire an Athlete's gut?
NCT ID NCT07828093
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers at the National Polytechnic Institute in Mexico are studying whether a daily agave fiber supplement changes gut bacteria and physical performance in healthy adult athletes. Twelve participants take 10 grams of agavins in warm water every day for six weeks. The team measures bacterial populations in stool samples, VO2max, lactate, and creatine kinase before and after the supplement to see if any shifts in gut microbes line up with changes in performance or metabolic stress.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- agave inulin fiber supplement
- What this could lead to
- If agave fiber changes gut bacteria in ways that help athletes, it could point toward simple dietary strategies for performance and recovery.
- What could go wrong
- This is a tiny study of 12 athletes with no control group, so any changes seen may be due to training, diet, or chance rather than the fiber itself.
