Addiction? Like you're physically addicted to them? IF so, then you must re-evalute what you are taking for sure.
Maybe it's more like "Supplement Neurosis". I myself suffer from this very condition. It manifests like this: First, I listen to a Robb Wolfe podcast or read a new article on Mark's Daily Apple or something in which they talk about a study (or some such thing) in which it was discovered that modern people are drastically deficient in "such and such" which causes obesity, acne, unattractiveness and general lack of cool factor. Next, I run out and buy a crap load of "such and such" and take it morning noon and night until one day I forget what the heck I was taking it for (hmmmm maybe some Gingko Biloba?). I stop taking it and by that time I am on to something else.
I guess what I am saying is sure, cover your bases with some basics, stay paleo (which should reduce your need for mongo antioxidants anyway), save some of the $$ you are spending on pills and buy some good food.
Some guy I was listening to on a podcast once said (I can't remember who or when - so I am going to get some Gingko for sure now), "Supplements are the most refined food you can get."
PS Most of the ingredients come from China anyway - and we won't even let our kids play with toys made there!!!!
