I'm no fan of the FDA, but one thing they *do* need to be more involved in is the assurance of quality of nutritional and nutraceutical supplements. At present, there is absolutely no assurance that the ginseng, gingko, horse chestnut, or any other of the myriad herbals available on the market are even half the strength of what the manufacturer says they are. Getting some accuracy on the labels would be a very welcome thing for all of us, and you can bet your bottom dollar that left to the manufacturers, that ain't gonna happen.
Oh yeah, while they're at it, cleaning up the Food Facts labels (which allow for up to a 15% margin of error) would be good to do.
