Understanding Effectiveness Scores
Our effectiveness scores range from 1 to 10, based on the quality and quantity of scientific research supporting a supplement's benefits. Here's what each score means:
- Score 10/10
- Ample scientific research demonstrates that the supplement is both highly effective and safe for long-term use.
- Score 9/10
- Strong scientific evidence supports the supplement's effectiveness, but some minor gaps in research remain.
- Score 8/10
- Solid evidence suggests the supplement is effective, but research is not as extensive as higher levels.
- Score 7/10
- Moderate evidence shows the supplement is effective for certain purposes, with limited population studies.
- Score 6/10
- Some evidence supports the supplement's effectiveness, but research is mixed.
- Score 5/10
- Limited evidence of effectiveness; may have potential benefits, but more research is needed.
- Score 4/10
- Minimal research on effectiveness.
- Score 3/10
- Inconclusive results regarding effectiveness.
- Score 2/10
- No scientific evidence supports effectiveness.
- Score 1/10
- Scientific evidence concludes that supplement is ineffective for purpose.
How We Rate Supplements
Our ratings are based on peer-reviewed scientific studies, clinical trials, and meta-analyses. We consider factors such as study quality, sample size, reproducibility, and the overall body of evidence.
