I was perplexed by your post because I don't think of things like vitamins or probiotics as falling under the category of "CAM". Fish oil even comes in a prescription dose (Lovaza). I think of CAM as encompassing things more like naturopathy and homeopathy or things like are pictured in the article. Will you avoid colds by taking Airborne? Probably not. If you are deficient in Vitamin D, though, taking Vitamin D is conventional medicine. If you are fat, taking an "herbal remedy for weight loss" is probably not backed by conventional medical practices and, therefore, would be "CAM".

I don't think anything you are doing counts as CAM as defined by the author. I had a doctor who would actually test blood levels to determine supplement needs but most doctors don't do that so you can only go by how you feel. That doesn't mean you are not following conventional medical wisdom by taking vitamins and probiotics.
