Wheyindex FAQ
How does Wheyindex calculate its product scores?
Our proprietary 100-point scoring algorithm is based on a health-first framework. We analyze key factors including ingredient quality and cleanliness, sugar and artificial additive content, protein concentration per serving, and the verification of dietary claims. The system applies consistent weights to these categories to generate an objective, comparable score for every product.
What is "Price per 25g of Pure Protein" and why is it important?
This is a standardized metric we calculate by determining the actual amount of pure protein in a serving, then working out how much it costs to get 25 grams of that protein. It's crucial because packaging and serving sizes vary wildly, making direct price comparisons misleading. This metric reveals the true cost efficiency of any product.
How often is the data on Wheyindex updated?
We are built on a scalable, continuous data model. Our product database and pricing information are updated regularly to reflect new product launches, formula changes, and current market prices from major retailers. Our "Inflation Tracker" feature is powered by this live data, providing insights into price trends over time.
Does Wheyindex only review whey protein?
While our name and foundation are in whey protein analysis, our platform has scaled to include a wide range of protein types. You can filter and compare plant-based proteins (pea, soy, rice blends), egg white, beef, and casein products, applying the same rigorous, objective scoring system across all categories for a comprehensive view.
