I am 76 years young and have been lucky to have a good digestive system. However, I think everyone should assist the body's "sewer system" to maintain a healthy system. Periodically, I have used "colon cleanse" herbal capsules, digestive enzymes, and probiotics on a sporadic basis.
All human "waste" has a bad odor, but after taking BIO X4, I experienced a new first! This product must have reached nooks and crannies that had been missed for years! The probiotics have to be the very best.
I did not notice any "appetite control" difference, but I know green tea is beneficial. The digestive enzymes worked fine, but so have other products.
Bottom Line: Yes, I would recommend this to a friend
