Wheyindex FAQ

How does the WheyIndex score work?

The WheyIndex score is a comprehensive, proprietary algorithm that evaluates products on a 100-point scale. It analyzes multiple factors derived from the product's label and data, including ingredient purity, the presence of additives or fillers, sugar and fat content, protein concentration per serving, and adherence to specific dietary claims. A higher score indicates a cleaner, more transparent, and generally higher-quality formulation based on our health-focused criteria.

What does "Price per 25g of Pure Protein" mean?

This is a standardized metric we calculate to allow for fair price comparisons between different products. Since containers vary in size and servings contain different amounts of actual protein, the retail price can be misleading. We normalize the cost by calculating how much you pay specifically for 25 grams of protein from each product, revealing the true value and helping you find the most cost-efficient option.

How many products are in the WheyIndex database?

WheyIndex maintains a curated and constantly updated portfolio of over 400 verified protein supplements. This includes a wide range of brands, from mainstream bestsellers to niche, clean-label options, covering whey concentrates, isolates, blends, and plant-based vegan proteins to cater to diverse needs and preferences.

Can I trust that the product data is accurate?
