Probiotics are live microorganisms—such as bacteria and yeasts—present in fermented foods, supplements (both over-the-counter and prescription) and even beauty products. They help the body digest food, destroy bad bacteria and provide vitamins, among other benefits, according to the National Center for Complementary and Integrative Health (NCCIH). Probiotics work mainly by impacting microorganisms found in the microbiome of the large intestine, which houses trillions of bacteria, fungi and microbes (small living things). Probiotics run the gamut, too, when it comes to types—their name includes a Latin name for genus and species, followed by their specific strain. There are many different strains of probiotics—and each delivers different health benefits. Common probiotics include those in the groups Lactobacillus, Bifidobacterium, Saccharomyces, Streptococcus, Enterococcus, Escherichia and Bacillus. Probiotics: What You Need To Know.
