^Here's a blog post written by an actual doctor on the subject.
http://theness.com/neurologicablog/i...ns-and-cancer/ Oh, I should mention, the blog post is mainly analysis of the quality of the study cited, but the author notes at the beginning of the post that 20 years of evidence have shown that there is no health benefit from taking multivitamins.
Even that fuckwad, Dr Oz, recommended people at least lower their vitamin doses on his show -- and if Dr Oz is wary of a supplement, you know it must be serious!
