Anybody take vitamin supplements and or fish oil gel caps?

[Fluid Power]

My boy is racing motocross and I have been riding with him. I have been working on getting my self into race shape for an assault on the 40+ class next year. I had a physical and the Doctor suggested a multi-vitamin. My cholesterol level is border line high (hereditary, thanks Dad!) If it gets much higher the Doc will put me on meds. I have heard that a side effect is muscle degradation. I would like to try a natural way to reduce it before the drug route. It goes without saying I work out and eat healthy already, so I am not trying to be a healthy couch potato! What vitamins are you guys taking?
