False advertising is the use of false, misleading, or unproven information to advertise products to consumers. The advertising frequently does not disclose its source. One form of false advertising is to claim that a product has a health benefit or contains vitamins or minerals that it in fact does not. Many governments use regulations to control false advertising. A false advertisement can further be classified as deceptive if the advertiser deliberately misleads the consumer, as opposed to making an honest mistake.
