he must have changed his lifestyle as well or he will end up in the same position or worse at some point. if glycos do heal, and i believe they contribute mightily, then it is because they are correcting the body to some natural pre-existing state(involving intestinal flora, i believe). then of course one can cease the glycos and let nature be your guide. these do not make good mlm customers and may be at the heart of the changes in mannatechs products in order to lengthen and/or perpetuate use. then there are always those who refuse to change and will need it until they die - GOOD mlm customers!
