Can someone explain if Kevetrin is absorbed into tissue and remains in the body or if it is in the body and then expelled. I hope someone take pity on me and explain like you would to a child because when I read your posts I get that feeling. I just don't have the education in science. What is the active life of Kevetrin. I know it has to do with the dose but if it is absorbed is this a cumulitive effect? I hope you don't skip over my post as sometimes I am not as serious as some of you but believe me I do take Dr Menon very seriously as he will be a Nobel winner in science and that will be just one of many many awards that he will collect not to mention his life story in print and on the big screen. Ben Kingsley would do him justice.
