You are in a store, considering what to buy and you see a claim on a product -- maybe your cleaning product bears the Green Seal label, or a claim on the carton says the eggs are "Animal Welfare Approved." What's it mean? Is it backed up by good standards? Can you trust it? Check it out on Label Lookup on this web site or in our updated iPhone app, available here. We've researched roughly 200 different claims that can be found on product labels and gathered what we learned into this tool so that you can make informed product choices.
