Does Probiotic Athletes Respiratory Health Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Probiotic Athletes Respiratory Health Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - Moreover, repeated exhaustive exercise and high training loads may lead to a transiently depressed immune function, associated with an increased risk of upper respiratory tract infection (URTI). [Heimer M (2022); evidence level 1] - Conclusion The effects of probiotics on immune system, URTI, and GI symptoms in athletes, healthy adults and recreationally active individuals remain inconclusive. [Heimer M (2022); evidence level 1] - Background The use of probiotics in sports has been growing in recent years, as up to 50% of athletes suffer from training- and performance-limiting gastrointestinal (GI) problems. [Heimer M (2022); evidence level 1] - In most cases, probiotic supplementation is effective in two major types of exercise: probiotics show strain and duration-specific effects both on endurance-based and intermittent-exercise associated sport. [Teglas T (2025); evidence level 4] - The supplementation can reduce inflammatory process activity and stress-related factors, e.g., anxiety, depression, in intermittent exercise-associated sports. [Teglas T (2025); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
