I take various minerals on days that I think I'm low in them, fish oil on days where I need it, vitamin d, vitamin e, k2, alpha-lipoic acid, and probiotics. I look like a supplement junkie but I swear that they're all having a beneficial impact. I think a lot of people underestimate the importance of optimal nutrition or overestimate their body's ability to absorb nutrients. I have to side with Mark's take on a oh-my-god-assloads-of-nutrients-in one supplement approach. I think as long as you get good quality stuff there is a lot more benefit than risk.
