How We Create Content
- Gather product data from manufacturer labels and verified listings
- Convert everything to comparable metrics (price per 100g protein, calories per 100g protein)
- Calculate rankings from objective data
- Cite scientific claims to authoritative sources (peer-reviewed journals, NIH, Harvard, Cleveland Clinic)
- Publish with methodology, sources, and last updated dates
Data Sources
Product data comes from manufacturer labels, verified retailer listings, and third-party testing (Consumer Reports, Clean Label Project for heavy metals). All data is traceable to its source.
Updates
Prices are updated regularly. Product information changes when manufacturers reformulate. Safety and certification articles are reviewed every 6 months. Each page shows when it was last updated.
Corrections
Found an error? Contact us with details. We investigate all reports within 48 hours and correct verified errors promptly. Significant corrections are noted on the page.
Independence
Brands cannot pay for rankings or placement. We don't publish sponsored content. Affiliate commissions don't affect our analysis. We maintain independence from all supplement manufacturers.
Affiliate Disclosure
We may earn commissions from retailer links. These commissions don't influence our rankings or recommendations. Products appear based on data, not commission rates.
Research Standards
Scientific claims cite peer-reviewed journals, government agencies (NIH, FDA), and medical institutions (Harvard, Cleveland Clinic). We prioritize recent research and link to primary sources. Content is for education only—consult a healthcare professional for personal health decisions.
What We Don't Do
We don't review taste or mixability—those are subjective. We're data analysts, not doctors, so we don't give medical advice. We provide data and analysis, not subjective product reviews.
About Us
Built by data analysts. We analyze 47+ protein powders across US, UK, Canada, and Australia markets using reproducible formulas. Rankings are based on data, not opinions. Every calculation can be verified.
Transparency
Every calculation is reproducible. You can verify our metrics yourself using price, serving size, protein per serving, and calories from any product label.
