Consumption of probiotics and prebiotics modulates intestinal microbiota composition and metabolic activity, which is associated with health benefits including reduced risk of intestinal infections, respiratory tract infections, CVD, osteoporosis, urogenital infections, and inflammatory bowel disease.

Probiotics and prebiotics show promise for various health conditions, but results vary by strain and specific health issue. Do not expect a universal cure. Consult a healthcare provider for strain-specific recommendations for conditions like IBS or antibiotic-associated diarrhea, as evidence is mixed for some applications.
