Yakult for athletes? study tests probiotic against Race-Day sniffles

This study looked at whether a daily probiotic drink (like Yakult) can reduce cold symptoms in triathletes, who often get sick from intense training. 80 healthy adult triathletes drank either the probiotic or a placebo before and after a competition. Researchers tracked symptoms like sore throat and stuffy nose, and measured immune markers in saliva and blood. The goal was to see if this simple, non-drug approach could support athletes' immune health during stressful events.
