Please do explain how taking 400mg of caffeine per day constitutes an addiction. I also take a daily multivitamin that contains ginseng, and a 'super' vitamin B pill. The latter makes the biggest difference in energy levels. I guess I'm 'addicted' to vitamin B, as well. I would say the difference between addiction and supplementation is not in what you take, but rather what happens if you do not take it. I'm supplementing with Vitamin D but I often forget to take it, sometimes for days. Now would you be able to forget your caffeine? If yes, I'd say there's no addiction. If you'd start feeling cravings in a few hours, that's a different story ...
