What are probiotics?

Although people often think of bacteria and other microorganisms as harmful "pathogens", many bacteria are actually helpful. Some bacteria help digest food, destroy disease-causing cells, or produce vitamins. Many of the microorganisms in probiotic products are the same or similar to the microorganisms that live naturally in our bodies.

In adults, probiotics are the third most commonly used dietary supplement outside of vitamins and minerals. Adult use of probiotics quadrupled between 2007 and 2012. The 2012 NHIS also found that 300,000 children aged 4 to 17 years (0.5%) had taken probiotics in the 30 days before the survey.
