Wheyindex
Objective 100-Point Scoring System
Wheyindex's foundational feature is its transparent, data-driven scoring system. Each product is evaluated on a consistent 100-point scale based on key factors like ingredient purity, absence of unwanted additives, and protein quality. This objective metric allows for direct, hype-free comparisons between brands, empowering you to see the true quality behind the packaging. It transforms subjective opinion into an actionable score, guiding your evolution from a confused buyer to an informed consumer who understands exactly what they are putting into their body.
True Cost Analysis (Price per 25g Protein)
Moving beyond the misleading price-per-container model, Wheyindex calculates the true cost of protein by standardizing prices to a "price per 25g of pure protein." This critical feature ensures you are comparing the actual value of the protein content itself, not the fillers or packaging. It allows for an apples-to-apples financial comparison, helping you identify the most cost-effective options that fit your budget without compromising on your nutritional goals, a key step in refining your supplement strategy.
Advanced Dietary & Allergen Filtering
The platform supports your specific health journey with powerful filtering options. You can narrow down the vast database by dozens of criteria, including dietary claims (Vegan, Keto, Grass-Fed), allergen concerns (Gluten-Free, Soy-Free, Nut-Free), and ingredient preferences (No Artificial Sweeteners, No Added Sugar). This precision allows individuals with dietary restrictions or clean-label goals to quickly find safe and suitable products, eliminating the risk and frustration of manual label reading and accelerating your path to the perfect match.
Comprehensive Product Database & Inflation Tracker
With over 400 regularly updated products, Wheyindex provides an unparalleled market overview. This is coupled with tools like the Inflation Tracker, which monitors price changes over time. This combination ensures you have access to the latest products and can make purchasing decisions based on current market value and availability. It reflects an understanding that the supplement landscape is dynamic, and your tools for navigating it should evolve to provide real-time, actionable insights.

Wheyindex FAQ
How does Wheyindex calculate its objective score?
The Wheyindex score is derived from a comprehensive analysis of multiple data points for each product. Key factors include the purity and quality of the protein source, the presence and quantity of sugars, artificial sweeteners, fillers, and additives, as well as verification of dietary claims. Each criterion is weighted and combined to generate a transparent score out of 100, designed to reflect the overall quality and cleanliness of the product from a nutritional standpoint.
What does "Price per 25g of Protein" mean and why is it important?
This metric standardizes the cost by calculating how much you pay for 25 grams of pure protein from any given product. It is crucial because packaging sizes and serving suggestions vary wildly, making price-per-container comparisons misleading. This figure allows for a true value comparison, ensuring you understand the actual cost of the protein you are consuming, which is essential for making budget-smart decisions on your fitness journey.
How often is the product data and pricing updated?
Wheyindex is committed to providing current information to support your evolving needs. Product data and pricing are tracked and updated regularly to reflect market changes, new formulations, and availability. Features like the Inflation Tracker are built specifically to monitor these trends over time, giving you confidence that the comparisons and recommendations are based on the latest available information.

Absolutely. Wheyindex is designed for all protein seekers. You can easily filter the entire database by selecting "Vegan" under the Dietary Claims filter. This will instantly show you all plant-based protein powders, which you can then further sort by score, price per 25g protein, or other dietary needs like being Soy-Free or Gluten-Free, guiding you to the ideal plant-powered option for your regimen.
