I'm a supplement skeptic. I don't have any science to back up my thinking, just opinions based on my personal experience. I don't take any supplements and I'm in the camp that says that, generally speaking, the necessary nutrients can be had from a well-balanced diet. I'm not dogmatic about it - if there's a known deficiency or health issue and there's evidence a targeted supplement will help, by all means, I would take it. From my personal experience, I don't see supplements - at least not at this point in my life - as necessary or helpful.
