Which misleading marketing tactic is commonly used to promote supplement sales?

Testimonials are a common marketing tactic used to promote supplement sales because they are designed to create a personal connection with potential customers. People often trust the experiences of others who seem relatable or have similar needs. This form of marketing can be particularly misleading, as testimonials may not fully represent the general effectiveness of a product or its potential risks. Oftentimes, they are selected specifically because they tell a compelling story or demonstrate extreme results, which may not be typical or scientifically validated.

While other choices, such as scientific endorsements and public health endorsements, are also used in marketing, they might carry more credibility when supported by robust evidence. Regulatory approval can suggest a level of safety or efficacy, but it is not commonly used as a tactic in the same direct, anecdotal manner that testimonials are. Overall, testimonials exploit the emotional appeal of personal stories, aiming to persuade consumers based on emotions rather than objective data.
