uhh a little more than that. a company like centrum or ON has just a little more $$$ for research than some random dude hand-filling capsules in his basement.
taking the " natural" approach isn't the end all be all either. the FDA can be lobbied just like any other regulatory body. there are products like creatine which aren't FDA regulated, yet research shows their supplementation is beneficial.(much to the dismay of the media)
the vegetables you're saying are so good are loaded with stuff that you assume is ok just because the FDA says so. you're taking the opposite extreme of the spectrum and like most things, the answer lies in the middle. are there junk supplements out there? of course. are there some that are physiologically beneficial that people should take? absolutely.
PS jogging is about the worst form of chronic exercise someone can have for life long health. increases body fat, lowers muscle mass, high impact on joints, anatomically unfavorable (humans are made to sprint and walk, not run for long periods of time). walking at an incline is a much more efficient and less catabolic way of exercising. not hating on running, if its your thing, do it, just saying don't do it for health claims.
