Among people who use dietary supplements, the most popular products at the end of 2010 were fish oil, multivitamins, vitamin D, calcium and CoQ10 according to a survey by ConsumerLab.com. Use of vitamin D surged in 2010 to 56.2% of those surveyed, up from 47.9% in 2009 and 36.9% in 2008 – a 52% increase over the two-year period. The ConsumerLab.com survey is conducted each November and is based on more than 6,000 responses from a sampling of subscribers to the ConsumerLab.com free e-newsletter. Most respondents in the survey use multiple supplements.
Among the 2010 survey’s other key findings:

·         Fish oil continued its rise in popularity, used by 75.7% of those surveyed, up from 74% in 2009.
·         Multivitamin use declined to 70.1% last year from 72.0% in 2009 and 73.8% in 2008.
·         Women were much more likely than men to have taken vitamin D, calcium, or probiotics. Men were more likely than women to have taken coQ10, herbs and extracts, glucosamine/chondroitin, vitamin E, resveratrol, amino acids, nutrition drinks and powders, and several other supplements.
·         Younger adults were more likely to have used a multivitamin than older adults: 73.0% of people aged 35 to 44 used a multivitamin, compared to 67.9% of those aged 75 to 84. Younger adults were also more likely than older adults to have used amino acids, nutrition /protein drinks and powders, green tea, nutrition bars, iron, and several other supplements. 
·         Older adults were more likely than younger adults to have used vitamin D, calcium, CoQ10, vitamin C, vitamin E, resveratrol, vitamin K, and red yeast rice. For example, 64.9% of those aged 75 to 84 used vitamin D, compared to 48% of those 35 to 44.
·         Calcium was the fourth most popular supplement, used by 55.3% of respondents, up from 51.2% last year. 
·         Use of CoQ10, the fifth most popular supplement, fell in use from 55% to 53% of respondents.
·         Other than among the top five supplements, the largest changes since 2009 in the use of the other 26 types of supplements covered in the survey were the use of herbs and extracts (down from 44% to 37.6%) and glucosamine/chondroitin (down from 38.5% to 35.3%).
·         Among ten types of merchants from which people purchased their supplements, the most common was online stores, used by 46.5% of respondents – up from 44.1% in 2009 and 39.9% in 2008. The increase was offset by small declines in the use of vitamin stores, mass merchants, and direct distributors.
·         Respondents also rated 1,356 brands and 1,186 merchants they used. Among these, 70 brands and 33 merchants each received at least 100 to 1,707 consumer ratings. Those receiving the highest rating on overall consumer satisfaction within their specific market segment are listed on the ConsumerLab.com website.
