The role of probiotics in digestive health involves promoting a balanced gut microbiome, which is essential for proper digestion and nutrient absorption. Probiotics are live beneficial bacteria often found in fermented foods or supplements. They help maintain a healthy microbial balance in the intestines, potentially alleviating issues like bloating, constipation, and diarrhea. Additionally, probiotics can strengthen the gut barrier and support the immune system, leading to overall better digestive health.
