Probiotics are live microorganisms, often referred to as “good” bacteria, that have numerous health benefits. Good bacteria live in our digestive tract and are necessary for our bodies to function properly. Good bacteria help our body digest food, destroy disease-causing “bad” bacteria, and produce important vitamins, along with many other essential functions. Probiotics need to be living and be the same as or similar to the microorganisms that naturally live in our body to be effective.
