Should I take BSN amino or ON Opti-Women?

I have been working out in the gym for 2 months now. And I figured that it is about time to start taking some supplements. SO now I am starting to take ON Whey gold Standard protein. However, a lot of people tell me that I should as well take some amino or vitamins plus so that I can have extra result or whatsoever. Should I only take my protein or Should I add one of'em above? if so, which one is better?
