Research Summary
Clinical evidence supports probiotics for antibiotic-associated diarrhoea, irritable bowel syndrome, and immune support, though strain-specificity is crucial as not all probiotics demonstrate equivalent benefits. Meta-analyses show varying effectiveness depending on probiotic strains, duration of use, and individual microbiome composition. Quality and viability of CFU at consumption significantly impact outcomes, making product selection and storage critical factors.
