I wrote this article, New York News Radio – The voice of bad science, a few years ago, but it is still completely relevant. In fact, things have gotten much worse. The ads are slicker and more deceptive. None of these products work, but the makers offer them in the guise of money-back guarantees and free samples.
When it comes to advertisements for health products, and more, nearly every radio ad is highly deceptive.
When it comes to radio ads, it is de facto that the ad is misleading. Caveat emptor.
