What Are Probiotics?

The most common definition of probiotics is “live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.” Simply put, probiotics are bacteria that benefit people’s health when in the stomach and intestines.

In order to be called probiotics, bacteria must be alive when consumed, and their health benefits must be confirmed through scientific research. Some of their benefits include:


  • promoting intestinal health;

  • improving the immune system to help maintain health;

  • preventing chronic diseases like cancer, high blood pressure, obesity and diabetes; and

  • improving mental health.
