Lead with a specific clinical-study result
A callout states a real study result in plain numbers (in a 90-day study, participants averaged a named amount of change), so the claim is concrete and cited.

What it is
A prominent callout states a specific result from a real study in plain numbers, for example that in a 90-day placebo-controlled study participants averaged a named amount of change, with a footnote to the source.
Why it works
A concrete, cited number from a real study is the strongest trust signal a science-led product can give, far stronger than a clinically-studied badge, because it says exactly what happened and by how much.
How to test it
- Hypothesis
- Leading with a specific cited clinical result will lift add-to-cart rate by making the core claim concrete and defensible.
- Primary metric
- Add-to-cart rate (product page sessions)
- Guardrail metric
- Return rate, to confirm the promise is not over-set
