Traditional testimonials are subjective. A customer says your sleep supplement "changed their life" — but what does that actually mean? Without data, it's just an opinion, and opinions don't hold up to regulatory scrutiny or skeptical consumers.
Health-conscious consumers are more informed than ever. They've seen the fake reviews, the exaggerated claims, and the products that didn't deliver. They want proof, not promises.
Evidence-based testimonials bridge the gap between subjective experience and objective measurement. Here's how they work:
Participants connect their Oura, WHOOP, or Apple Watch to track real biometric changes during product use.
Establish baselines, track changes, and quantify improvements with statistical significance.
Use clinical-grade instruments like PSQI and PHQ-9 to measure subjective outcomes properly.
Generate marketing assets that are backed by real data and can withstand regulatory review.
A direct-to-consumer sleep brand ran a 30-day study with 150 participants. Results showed an average 23% improvement in deep sleep as measured by wearable devices, plus a statistically significant improvement in PSQI scores.
The brand now uses these verified results across their Amazon listings, website, and advertising — with full confidence in their claims.
Most studies run 30-90 days depending on your product category and the outcomes you're measuring.
We integrate with Oura, WHOOP, Apple Watch, Garmin, Fitbit, and most major wearable platforms.
Our methodology follows FDA guidelines for structure/function claims. For drug claims, we offer IRB-approved protocols.
