Probiotics for athletes

Probiotic supplementation with variety of Lactobacillus and Bifidobacterium strains showed the improvement of gastrointestinal symptoms during exercise training and competition in athletes. The most beneficial effects to reduce frequency and severity of gut symptoms and improve gut barrier function were demonstrated with multi-strain probiotic consortia. The efficacy increased with duration of probiotic supplementation.
