just watch, this is the tip of the iceberg, big pharma has been gunning for regulation of the vitamin/supplement industry so as to force most providers out of business (who but big pharma can afford to pay for clinical trials to back up the claims that folic acid helps unblock arteries, for example, not to mention the lavish "incentives" industry officials are used to receiving for "helping" a product get FDA approval....sick)
Of course, if docs had to write a script for a vitamin, mineral, or herbal supplement, perhaps they might actually have to educate themselves about these things.
