Probiotics are live microorganisms, typically bacteria or yeast, that are ingested or administered to help promote health, primarily by supporting or altering existing microbial communities in the body. In particular, they may aid in the prevention of disease by competing with harmful microorganisms and in the treatment of certain health conditions by influencing immune activity. Some of the most commonly used probiotics are lactic-acid bacteria, such as strains of Lactobacillus and Streptococcus, which are components of the human microbiome and have been used for centuries in the production of yogurt, cheese, and some pickled foods.
