Abstract

This paper sets out a practical operating model for consumer health teams that need commercially useful claims supported by transparent scientific reasoning. It connects claim definition, evidence appraisal, cross-functional governance and lifecycle review into one traceable system.

Plain-English summary

Claims work becomes fragile when wording, evidence and review happen in separate streams. A more reliable approach starts with the exact promise, defines the evidence question and gives each team a clear role in deciding what can be said.

The objective is not more process. It is a faster route to language the organisation can defend and maintain.

Key findings

Define the promise first

Evidence appraisal is meaningful only when the wording and context are clear.

Design for traceability

A reviewer should follow the reasoning without rebuilding the analysis.

Govern across functions

Medical, regulatory, legal and marketing roles should be explicit before final review.

Maintain after launch

Evidence files need ownership as products, claims and contexts change.

How this supports consumer health brands

The framework helps teams focus scientific effort on decisions with commercial value, identify important evidence gaps earlier and reduce late disagreement around claims and communications.
