Vitamins

I need to find some of the best multivitamins. I take vitamins most of the time. But I will admit when I run out, I tend to go a bit before buying more. I want to find some that are giving me the maximum benefits for the money. I went to a health store recently to get help & the person working there had zero idea of what I was talking about or needed. I left there empty handed. I guess I just need to do my own research.
