Watch for scams

Scammers have perfected ways to convince you that their products are the best. They often target people who have serious and chronic medical problems. Remember, if something sounds too good to be true, it probably is.

Be alert for these red flags:

• Big promises. Ads may call the product a "miracle cure," "scientific breakthrough," "secret ingredient" or "ancient remedy." Be skeptical of exaggerated claims.
• Cure-alls. The product claims to treat a wide range of symptoms or cure or prevent a number of diseases. No single product can do all of this.
• Testimonials. Stories from people who have used the product are not the same as scientific proof. If a product's claims were backed up by clinical studies, the manufacturer would say so.
• Limited-time offers and guarantees. These pitches are intended to get you to buy before you can evaluate the product's claims.
