About

Labdoor is a marketplace where consumers research, find, and buy the best supplements. To verify the purity and potency of these products, Labdoor first buys and tests actual dietary supplement samples: • We send each product to an FDA-registered laboratory for a detailed chemical analysis. • Our scientists then collect the laboratory results and use internal algorithms to translate this data into simple grades and rankings for consumers. • Find a product you love? Click "buy it now" to activate in-app purchases.
