I've noticed in the last few days that I'm experiencing some muscle fatigue and cramps. It's not severe, but I from what I've read here, it sounds like I need a magnesium/potassium supplement.

My question, I currently take Atkins Basic #3, Omega Oils, Calcium and L-carnitine. Would it be just too much to add another supplement (magnesium/potassium)?

I don't want to go overboard, but I don't want to deprive my newly-feeling-alive-again body of necessary nutrients either.
