Dietary supplements aren't always what they seem. You can identify fraudulent dietary products by the claims they make on their labels or in advertising, says the Food and Drug Administration. Here are some examples:
The label or advertising says the product is a "secret cure" or uses terms such as "breakthrough," "magical" and "miracle cure."
The label or advertising uses pseudo-medical jargon, such as "detoxify" and "purify" to describe a product's effects.
The label or advertising makes the claim that the product can cure a wide range of unrelated diseases. No product can do that.
