Do probiotics really work for the gut?

A large number of different types of microorganisms are present in the stomach and intestines. When normal, different types of microorganisms promote or inhibit each other, forming a balance that enhances the protective function of the mucosal barrier, and also promotes gastrointestinal digestion and absorption. When there is a disease, the microorganisms that are harmful to the human body multiply, while the beneficial bacteria are inhibited, and the balanced microbial environment in the gastrointestinal tract is broken, which is not conducive to the health of the gastrointestinal tract.
