What are probiotics?

Probiotics are good bacteria that are found in food or supplements. The definition is ”Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.” (WHO/FAO, 2002)

Important criteria for qualifying as a true probiotic is that health benefits should be proven in clinical trials. Furthermore, a probiotic product must contain the same bacterial strain(s) and the same dose that was used in the clinical trials.
