Among people who use multiple dietary supplements, fish oil/omega-3 supplements now top multivitamins in popularity, according to a recent survey by ConsumerLab.com. The survey also shows that vitamin D use jumped 30% since last year and resveratrol use surged by 66%. The ConsumerLab.com survey is based on 6,012 responses collected in November from a sampling of subscribers to the ConsumerLab.com free e-newsletter. Most respondents use multiple supplements.

“We conduct the annual survey to help direct our product testing toward categories and brands of greatest interest to our subscribers; but the survey also yields insight into the nutrition marketplace,” said Tod Cooperman, MD, President of ConsumerLab.com. Among the survey’s key findings:

· Fish oil/omega-3 supplements were used by 74.0% of respondents (up from 71.6% in 2008), followed in popularity by multivitamins, which were used by 72% (down from 73.8% in the prior year). Among the heaviest supplement users (10 or more per day), 87% used fish oil. The percentage of people using fish oil/omega-3 remained steady among those aged 35 through 74, dropping slightly among older people.
