These bacteria are found in our mouth, our stomach, our colon, everywhere you can think of. Many bacteria like living in our digestive system because they are heat lovers or acid lovers. Our digestive system is warm (body temperature is 98.6 degrees) and it is also filled with acid. In our stomach, in particular, is a ton of acid. This acid is needed to assist in mechanical digestion. But probio lite bacteria love acid and can definitely withstand it, so they tend to find themselves there.
