How it works

This visualization maps 24 popular supplements across two key dimensions: quantity of research (number of studies) and quality of research (average methodological rigor). Bubble size represents consumer popularity, and color indicates the overall evidence grade.

Evidence grades follow a systematic framework: Grade A requires multiple large randomized controlled trials with consistent results. Grade D indicates insufficient evidence or research that contradicts popular claims. Data is sourced from systematic reviews and meta-analyses.

Key insight: The supplements with the highest popularity don't always have the strongest evidence. Some of the most marketed supplements (like apple cider vinegar and biotin for hair) have the weakest scientific support.
