Some help with vitamin questions?

I am 20 years old, 5'8", 185 lbs. Not completely out of shape, but not at a peak either. i was just wondering is there a multivitamin or any vitamins out there that I can take for, basically, maximum health? Such as higher energy levels, better heart health, better immunity, etc. Now going to a health store website (gnc, vitaminshoppe) can easily answer this question, but the tricky part is the fact that I dont want to ruin any other parts of my body with these vitamins. I've heard aspirin can destroy your intestines after a while and I saw that one-a-day is made my bayer. I've also heard of a few multi vitamins giving acne.. I dont want anything that will also worsen parts of my body. Please help with your suggestions?
