What Evidence Is Acceptable for Substantiation?

Strong Evidence Sources

• Clinical studies: Peer-reviewed research on your product or ingredients
• Laboratory testing: Third-party testing results
• Customer data: Documented, verifiable customer outcomes

• Outdated studies: Old research that may not reflect current formulation

How Do You Structure Claims to Minimize Risk?

Use Qualified Language

Instead of absolute claims, use qualifiers:

Include Appropriate Disclaimers

• "Results may vary"
• "Based on a survey of 500 customers"
• "Individual results depend on multiple factors"
• "Past performance does not guarantee future results"

Specify Conditions

Be clear about when claims apply:

• "When used as directed for 8 weeks"
• "Combined with a healthy diet and exercise"
• "For eligible customers meeting program requirements"

What Claims Should You Avoid Entirely?
