Independent tests and reviews of vitamins, supplements, and nutrition products
ConsumerLab tests dietary supplements for quality, purity, and label accuracy using independent labs and publishes detailed reports behind a subscription paywall. It covers many of the same categories as Labdoor but adds clinical study references and updated lot testing. Unlike Labdoor's free public rankings funded by affiliate sales, ConsumerLab requires payment for full access, making it better suited for users who want frequent batch updates rather than one-time brand scores.
