Fund the Next Study
Clean Label Project buys products off the shelf the way any shopper does, and sends them to an independent, ISO 17025–accredited laboratory. Donations help pay for that testing. Our category studies analyze the category as a whole to identify areas of concern and establish meaningful benchmarks.
Our published studies already cover protein powder, infant formula, pet food, coffee, cereal, snacks and pediatric OTC medicines. What we test next is partly up to you.
