A 2024 Lancet Gastroenterology & Hepatology review confirmed that multi-strain probiotics containing Lactobacillus and Bifidobacterium species reduce antibiotic-associated diarrhea by 51% and improve IBS symptoms in 60% of patients. Daily supplementation with 10-50 billion CFU of clinically validated strains supports microbiome resilience, though strain specificity matters far more than total colony count.
