To our knowledge, no—and we have searched the web for similar projects. We believe we are the only organization and website to undertake a comprehensive survey of consumer knowledge about the quality of specific products and brands of supplements.

Several organizations do give information on brands and products that "pass the test" of various quality measures. ConsumerLab.com compares brands with formulas that show good results in clinical research. NNFA, NSF International and USP all have programs for inspecting manufacturing plants for compliance with good manufacturing practice (GMP) standards, and for testing individual products. These four organizations offer quality seals that help consumers see at a glance whether a brand or product has passed such testing.

In the spring of 2003, ConsumerLab began publishing the names of brands that "flunk" their tests—but is the only organization so far to do so. However, such information is limited to those products and brands tested by ConsumerLab. Knowledge about other shoddy brands does exist—and this survey makes it possible for people to share such knowledge with the public.
