New research reveals that gut microbiome composition directly impacts athletic performance, with elite athletes harboring specific bacterial strains that enhance endurance, recovery, and nutrient absorption.

Key Findings

A study comparing elite marathon runners to sedentary controls found runners had 3x more Veillonella bacteria, which converts exercise-produced lactate into propionate — a short-chain fatty acid that fuels muscles.

Actionable Steps

While you can't buy Veillonella supplements yet, research shows that eating 30+ different plant foods weekly, consuming fermented foods daily, and avoiding unnecessary antibiotics promotes a performance-enhancing microbiome.
