Importance of gut probiotics in human health. The probiotics play an important role in maintaining normal microbiota composition, metabolism and immunity. All these functions of probiotics are correlated with each other. Normal microflora decrease the gut infections and disorders alongwith strengthening the mucosal immunity. Probiotics as normal microflora help in synthesis of vitamins e.g. vitamin K, metabolism of lactose and lowers the level of cholesterol. Probiotics enhance the systematic immunity which further reduces the chances of allergy and inflammation by immunomodulation.
