Aviado Research · Methodology
How we rate supplement evidence.
Every claim in the Research Library is scored on a transparent 4-tier rubric and re-reviewed quarterly. This page documents how the rubric works, where our sources come from, how we handle disagreement in the literature, and why the ingredient-level Evidence Score is deliberately different from the product-level ProofMark.
The 4-tier evidence rubric
- Strong evidence
- ≥2 concordant RCTs or a high-certainty GRADE meta-analysis. Consistent effect across studies, low risk of bias.
- Moderate evidence
- 1 RCT plus replicated observational data. Effect plausible but not yet confirmed across multiple controlled trials.
- Preliminary
- Early human data, mixed results, or a single trial. Biological plausibility but insufficient replication.
- Insufficient
- Animal-only data, mechanism-only reasoning, or anecdotal reports. Not a rating of no effect — a rating of not enough evidence to judge.
