Labdoor is a testing lab that publicly verifies the quality of consumer products, starting with supplements. On Labdoor.com, consumers can find scientific product reviews and shop for hundreds of quality-tested supplements all in one place. They also offer a "Labdoor Certified" program to companies who submit every lot of their products to us for quality control testing. From their chemistry lab in South San Francisco, Labdoor analyzes the purity and potency of popular products to find out which ones have what they claim and if they have any harmful ingredients or contaminants. Then, they grade and rank those products, write reports, and publish that information for free, so consumers can confidently buy the best supplements for their needs.Something looks off?
