First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a daily probiotic drink (like Yakult) can reduce cold symptoms in triathletes before and after a competition. 80 healthy amateur triathletes drank either the probiotic or a placebo for 30 days before and 14 days after a race. Researchers tracked symptoms and immune markers to see if the probiotic helped.
