Renew Life Ultimate Flora Critical Colon 80 Billion leaves some questions to be answered. Many of the bacteria included have not been scientifically proven to aid digestive health. Many users have achieved positive results, but clinical studies are still lacking. It does not appear to actually cleanse the digestive tract or support weight loss. In fact, it is used to relieve symptoms of Crohn’s disease such as weight loss due to not absorbing nutrients properly. If you are looking for a weight loss supplement, this product is not likely to be helpful.
