Which of the following is a common advertising red flag?

• A. Satisfaction guaranteed
• B. Transparent scientific support
• C. Clear and detailed ingredient list
• D. Independent testing results

Answer: (A)

In evaluating health product ads, the red flags to watch for are marketing phrases that promise guaranteed results without evidence. The phrase about satisfaction being guaranteed is a classic red flag because it implies you’ll get your money back if it doesn’t work, but it doesn’t provide any real proof that the product is effective or safe. It shifts attention to a refunds policy rather than data, which can hide a lack of credible testing or proof behind the claim.

By contrast, signs like transparent scientific support, a clear and detailed ingredient list, or independent testing results point to backing for the claims and better credibility. So the guaranteed-satisfaction line stands out as the common ad red flag.
