Multi-vitamin for someone with an allergy to mold?

I'm a 24 year old woman who dearly needs to find a multi-vitamin that I can start taking every day. Ever since I was a child, I've been lactose-intolerant. As long as I take a lactaid suppliment, I am fine to eat dairy products but I still worry about osteoperosis because I don't eat much dairy or drink much milk. Also every couple of months I get a little anemic, and if I take an iron suppliment within a few days I feel back to normal. The problem with overall multi-vitamins for me is that I'm very allergic to mold and yeast. Any time I take a vitamin, I start throwing up and am extremely sick all day. I've heard that vitamins have yeast as well as B-12, which is also in the yeast family. Does anyone know if there is a vitamin out there that doesn't have yeast in it? I've been looking everywhere and haven't found one yet, but I know I'm not the only person who has an allergy to mold and yeast. Any help or advice would be greatly appreciated!!
