Men's Vitamins

I and my boyfriend have been planning to live together for quite sometimes now. I really wish it is going to happen soon (keeping my fingers cross). When this happen, I know I will look after his needs. I am starting to search around the most important vitamins for men when I stumbled upon this site that offer men's vitamin. The only problem I have is that I cannot choice which one is perfect for him since he have cardiovascular problem to deal with.
