If anyone is looking for informative naturpathic information about self healing through vitamins a good book to read is Natural Cures they dont want you to know about .I had seen the advertisement on TV a couple years back and i was always curious about the information in the book .A few months ago i was doing my routine MG info search on Google and i actually came across a site that had a ton of facts from the book.I dont think it has all of it , but it definatly has all the info you need .
