How have the massive amounts of dietary supplements on the market evaded significant regulatory oversight for so long? Dietary supplements are regulated as food, which means that for practical purposes the FDA only has the ability to pull them off the shelves upon a showing that they are harmful.
Many consumers use dietary supplements for the same purposes that someone may use a non-prescription drug. Some consumers actually feel safer using a dietary supplement because it is labeled as “natural,” rather than using an FDA approved over-the-counter drug. This doesn’t and shouldn’t make sense. Many natural things are harmful – would you eat any wild mushroom? Tobacco in in cigarettes is natural. Just because something is natural doesn’t mean that it is safe. Conversely, just because something isn’t “natural” in a drug doesn’t mean it is unsafe.
One of the main problems with regulating dietary supplements is that they are not all the same. We probably don’t need heavy regulation for Vitamin C, except maybe in formulation/content. We know, for example, that it is water soluble, so it is hard to take too much. So, maybe Vitamin C doesn’t pose the same safety concerns as other supplements. However, a recent article in Nature, vol. 510, pages 462-4, described different scientific viewpoints about the efficacy of vitamin supplements in healthy populations. So, unless you have a Vitamin C deficiency, then there is probably little reason to take it.
