The definitions of international authorized probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. The scientific basis for the prevention and treatment of bowel disease among the functions of probiotics has only recently been established. Probiotics, which are actively studied, are lactic acid bacteria, especially Lactobacillus and Bifidobacterium species.

The use of probiotics for prevention and treatment has been discussed in this review.
