Prevalence of Leading Types of Dietary Supplements Used in the Third National Health and Nutrition Examination Survey, 1988-94
This report presents the prevalence of the leading types of dietary supplements taken during the third National Health and Nutrition Examination Survey (NHANES III), 1988-94. To some extent, the leading types of supplements and order changed after stratifying the results by sex and age groups. Other major contributors were multivitamins with iron or fluoride taken by children, iron taken by adolescent and young adult females, and calcium taken by middle-aged and elderly females. There was also a high prevalence of use of potassium among middle-aged and elderly adults but this probably reflects its use as a medication rather than as a dietary supplement.
