Without sounding to harsh, pharmaceutical company's make billions of dollars on drugs...when they realize there's money to be made. Then they'll get in on it, I have been using supplements for years, when I was on dialysis I was never in the hospital....you need to broaden your spectrum and do more research. There's p[plenty of information on these supplements, even on main stream, Harvard, mayo, and quite a few others, and most doctors, I should say some doctors will not tell you .
