“….randomized, double-blind, placebo-controlled study was conducted to evaluate if Lactobacillus helveticus Lafti L10 supplementation during 14 weeks in winter can influence the duration, severity, and incidence of upper respiratory tract illness, as well as to monitor different immune parameters in the population of elite athletes.”
.
“39 elite athletes were randomized either to the placebo (n = 19) or the probiotic (n = 20) group.”
.
“The probiotic group received L. helveticus Lafti L10, 2 × 1010 Colony Forming Units.”
.
“Lafti L10 significantly shortened the upper respiratory tract illness episode duration and decreased the number of symptoms in the probiotic group…”
“Probiotic strain Lafti L10 can be a beneficial nutritional supplement for the reduction of upper respiratory tract illness length in elite athletes.”
