The results are based on responses to the most recent ConsumerLab.com Survey of Vitamin and Supplement Users. The survey is conducted each year in November/December among readers of ConsumerLab.com's newsletter who use ConsumerLab's information when choosing and using supplements and health foods. The ConsumerLab.com Survey was first conducted in 2002. Respondents are active supplement users, with 83% taking at least four different supplements daily. 

“The annual survey gives us insight into what is happening in the supplement market. We’re seeing stability at the top of the market with rapid growth in select categories, but otherwise small changes,” said Tod Cooperman, M.D., ConsumerLab’s President and Founder. “These trends guide our selection of the types and brands of products we independently test and review each year.” 

An extensive 150+ page report based on the survey is available and includes results not only for supplement categories, but for supplement brands, merchants, and demographic analyses.
