    Data from the National Health and Nutrition Examination Survey

    • Among U.S. adults aged 20 and over, 57.6% used any dietary supplement in the past 30 days, and use was higher among women (63.8%) than men (50.8%).

    • Dietary supplement use increased with age, overall and in both sexes, and was highest among women aged 60 and over (80.2%).

    • The use of two, three, and four or more dietary supplements increased with age, while the percentage of adults not using any dietary supplement decreased with age.

    • The most common types of dietary supplements used by all age groups were multivitamin-mineral supplements, followed by vitamin D and omega-3 fatty acid supplements.

    • From 2007–2008 through 2017–2018, the prevalence of dietary supplement use increased in all age groups among U.S. adults.

    Dietary supplement use is common in the United States (1). The additional nutrients provided by dietary supplements can help meet recommended nutrient targets but can also potentially lead to excess intakes (2,3). This report describes recent prevalence estimates for dietary supplement use among U.S. adults, the distribution of the number of dietary supplements used, and the most common types of dietary supplements used. Trends in dietary supplement use from 2007–2008 through 2017–2018 are also reported.
