Prebiotics is a general term to refer to chemicals that induce the growth or activity of microorganisms (e.g., bacteria and fungi) that contribute to the well-being of their host. The most common example is in the gastrointestinal tract, where prebiotics can alter the composition of organisms in the gut microbiome.
Probiotics. Probiotics contain various strains of bacteria that are similar to the natural healthy gut flora of the body. They are available at many health food stores as supplements, but are also added to some dairy products, such as yogurt. The most common species found are Lactobacillus acidophilus and Bifidobacterium bifidus. It is important to note that probiotics are live microgranisms and not the same as prebiotics, which stimulate growth of the probiotic bacteria.
