Labdoor
Labdoor is an independent supplement testing company that buys products off retail shelves and online sites, then sends samples to FDA-registered laboratories for chemical analysis of active ingredients and contaminants. The company publishes free quality scores and rankings across 44 supplement categories, calculated from Label Accuracy, Product Purity, Nutritional Value, Ingredient Safety, and Projected Efficacy, so consumers can make evidence-based purchasing decisions. Labdoor funds its free consumer reports through a "verified commerce" model, keeping approximately 10% of each product sale made through its site.

Problem
Consumers purchasing vitamins and supplements often rely on marketing claims, celebrity endorsements, or user reviews rather than objective quality data. Many products on the market contain ingredients that do not match their labels or include harmful contaminants, yet consumers have no reliable way to identify which supplements are safe and effective.
Solution
Labdoor independently purchases supplements from retail stores and online sellers, then sends samples to FDA-registered laboratories for detailed chemical analysis measuring active ingredients and potential contaminants. The company calculates a Quality score for each product based on Label Accuracy, Product Purity, Nutritional Value, Ingredient Safety, and Projected Efficacy, then publishes results and expert reviews for free. Consumers can browse rankings across 44 supplement categories, compare products, and purchase recommended items directly through the site. Labdoor maintains independence by refusing manufacturer contributions or donations, and its "verified commerce" model uses revenue from product sales to fund additional testing and publishing.
Target Audience
Primary users are health-conscious consumers who purchase dietary supplements and want evidence-based quality information before buying, as well as supplement manufacturers seeking independent validation of their products through Labdoor's enterprise testing services.
