The term probiotic is derived from the Latin preposition âpro,â which means âforâ and the Greek word âbioticâ meaning âbiosâ or âlifeâ. The concept that the gut flora can be modified and harmful microbes replaced with beneficial ones was first introduced in 1907 by a Russian scientist called Elie Metchnikoff.
Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. We usually think of bacteria as something that causes diseases. But your body is full of bacteria, both good and bad. Probiotics are often called good or helpful bacteria because they help keep your gut healthy. Probiotics are naturally found in your body.
