May 5 marks the 29th World Gut Health Day. In our gut, there are trillions of microbiota, some of which are beneficial bacteria that live for a long time.

Some are pathogenic bacteria that will destroy the conditions when the intestinal microecology is destroyed. These gut microbes, especially beneficial microbes, regulate and influence our health all the time. People often hear that probiotics have such and such functions, it seems to be an "all-round" player. But this is just a general term, it is necessary to select specific strains that have corresponding clinical studies to confirm this function.
