This is critical for making informed, timely decisions on pricing, marketing spend, and product profitability without manual data reconciliation.
Retention Intelligence & Churn Prediction
The AI continuously analyzes customer behavior patterns to identify at-risk subscribers before they cancel.

This is essential for maintaining efficient ad spend and acquiring customers profitably without constant manual intervention.
Wheyindex
Objective 100-Point Scoring System
This is the cornerstone feature you cannot do without. Every protein powder is evaluated against a strict, health-first algorithm that analyzes ingredient quality, additives, and nutritional profile. The resulting score, from 0 to 100, provides an immediate, unbiased benchmark. This eliminates guesswork and marketing hype, giving you a clear, numerical truth about a product's purity and nutritional value, so you can prioritize what truly matters for your body.
True Cost Per Protein Calculator
Price tags are deceptive. WheyIndex provides the essential metric of "Price per 25g of Pure Protein," standardizing cost across all brands and container sizes. This critical feature allows for direct, apples-to-apples financial comparisons, ensuring you identify the most cost-effective source of quality protein. It is a fundamental tool for smart budgeting, preventing you from overpaying for fillers, water, or clever packaging.
Advanced Filtering & Dietary Compliance
With over 50 specific filters, finding your perfect match is not just easy—it's precise and necessary. You can filter by protein type (isolate, concentrate, vegan blend), dietary needs (gluten-free, dairy-free, soy-free, rBGH-free), ingredient preferences (no artificial sweeteners, no added sugar), and brand. This level of granular control is vital for anyone with allergies, dietary restrictions, or specific health philosophies, saving hours of manual label reading.
Inflation & Price Tracking
In today's economic climate, tracking cost changes is essential. WheyIndex's inflation tracker monitors price fluctuations over time, providing crucial market insight. This feature allows you to identify the best time to buy, understand long-term value, and avoid purchasing during price spikes. It transforms you from a passive consumer into an informed buyer, protecting your investment in your health.
Use Cases
Finsi OS
Reducing Customer Churn Proactively

Wheyindex FAQ
How does WheyIndex calculate its objective score?
The score is derived from a proprietary, health-first algorithm that analyzes multiple data points. Key factors include the purity and quality of protein sources, the presence and quantity of unwanted additives like fillers, gums, artificial sweeteners, and sugars, as well as verification of dietary claims. A higher score indicates a cleaner, more transparent, and nutritionally superior product based on these consistent criteria.
What does "Price per 25g of Pure Protein" mean?
This is a standardized metric that calculates the actual cost of the protein content alone, excluding other ingredients. It is calculated by determining the total price of the container and the total grams of protein it contains, then normalizing it to a 25-gram protein cost. This is the essential figure for true cost comparison, as it neutralizes the effect of varying serving sizes and filler content across different products.
How often is the product data and pricing updated?
WheyIndex is committed to providing current and accurate information. The platform's data, including prices and product availability from retailers like Amazon, is updated regularly. The "Last Updated" date on the website indicates the most recent data refresh, ensuring users are making decisions based on the latest market information.
Can I use WheyIndex to find vegan or plant-based protein powders?
Absolutely. WheyIndex is a comprehensive comparison tool for all protein supplements. You can use the "Protein Type" filter to select "Vegan" blends or use the "Dietary Claims" filter to select "Vegan." The platform will then show you all plant-based powders, complete with their objective health scores and true cost analysis, making it an essential resource for vegan athletes and consumers.
