Do you take a daily vitamin?

I've been researching this subject lately (and while I am FAR from an expert) a lot of what I read worries me. 

My husband is a religious multi-vitamin taker. But more and more research suggests that not only is he wasting his money - he may be harming his health. 

I am talking about articles like this: http://www.npr.org/blogs/health/2013/12/17/251955878/the-case-against-multivitamins-grows-stronger

and this: http://annals.org/article.aspx?articleid=1789253

Again, I am not expert. I am just worried about my husband. What do you think?
