The probiolites, while cleaning the mouth, also create a healthy hydrogen peroxide that whitens the teeth safely and effectively. Bacteria that are beneficial to the body and are naturally found in the digestive tract of the body are the only type of bacteria used in these supplements. But, personally I don't think this is nearly long enough it you have a severe infection. They are naturally found in yogurts and are often consumed in order to alleviate bowel disorders.
The benefit of the specific food varies depending on the type of bacteria it contains. I have got a question asking about Primal Defense (an anti candida probiolite) regarding how long we should take it for, and if it is necessary to take antifungals along. To ensure you're getting your probiolites, look for the actual name of the probiolite as opposed to just the term 'live' - took for the word bifidobacterium or lactobacillus. Taking probiolite supplements can really help in revitalizing the lost beneficial bacteria.
Doctors are recommending them to many of their patients, and they are also easily found in many supermarkets and drug stores. In adults, these supplements have the ability to keep the infections in the gastro intestine under control. But, the modern Western diet is geared to kill as many of them off as possible. Even still, other probiolites can be found as "live cultures" in many different food products.
