Our Methodology
Understanding how we calculate supplement value using evidence-based health economics principles.
QALY Valuation
We use Quality-Adjusted Life Years (QALY) as our primary metric for measuring health benefits. One QALY represents one year of life in perfect health.
Standard QALY Value
$100,000
Based on health economics literature and policy thresholds
ROI Calculation
Return on Investment is calculated by comparing the monetary value of health benefits against the cost of supplementation.
Formula:
ROI = (QALY Gain x $100,000 - Cost) / Cost
Evidence Levels
Strong Evidence
Multiple randomized controlled trials with consistent results and meta-analyses
Moderate Evidence
Several clinical trials with generally positive results, some inconsistencies
Limited Evidence
Few clinical trials, preliminary research, or observational studies only
Emerging Research
Early-stage research, animal studies, or theoretical mechanisms
Data Sources
- PubMed and medical research databases
- Cochrane systematic reviews
- Clinical trial registries
- Health economics literature

Important Limitations
- QALY estimates are approximations based on available research and may vary by individual
- Supplement efficacy depends on individual factors including genetics, health status, and lifestyle
- This tool is for informational purposes only and should not replace medical advice
- Prices may vary by brand, retailer, and location
