Multivitamin/mineral supplement contribution to micronutrient intakes in the United States (806.15)

Multivitamin/mineral supplements are the most common dietary supplements consumed in the United States; however, intake data specific to how multivitamin/mineral supplements use contributes to micronutrient intakes among Americans are absent from the current scientific literature. This analysis aimed to assess contributions of micronutrients to usual intakes derived from multivitamin/mineral supplements and to compare those intakes to the Dietary Reference Intakes for U.S. residents aged 蠅4 y according to National Health and Nutrition Examination Survey, 2007‐2010 (n = 16,444). We used the National Cancer Institute method to assess usual intakes of 21 micronutrients. Our results showed that 51% of Americans consumed multivitamin/mineral supplements containing 蠅9 micronutrients. Large portions of the population had total usual intakes (food and multivitamin/mineral supplement use) below the estimated average requirement for vitamins A (35%), C (31%), D (74%), E (67%), calcium (39%), and magnesium (46%). Only 0, 8%, and 33% of the population had total usual intakes of potassium, choline, and vitamin K above the adequate intake when food and multivitamin/mineral use was considered. The percentage of the population with total intakes greater than the tolerable upper intake level was low for all nutrients; excess intakes of zinc were the highest (3.5%) across the population of all the nutrients assessed.
