Data from the 2007–2008 National Health and Nutrition Examination Survey (NHANES) suggested that nearly half of the US adults age 20 to 69 reported taking at least one dietary supplement in the past month. The following factors were associated with a greater likelihood of supplement use: females, older adults, people with a higher level of education, non‐Supplemental Nutrition Assistance Program (SNAP) participants, and those in food secure households. In order to compare nutrient intakes between supplement users and non‐supplement users, daily intakes of eight nutrients were analyzed. When only considering nutrients from food, supplement users tended to consume greater amounts of Vitamin A, Vitamin C, Vitamin E, Folic acid, and Calcium; whereas, there was no association between supplement use and the remaining nutrients: Vitamin B‐12, Zinc and Iron. After including daily supplement use, supplement users consumed greater amounts of all eight nutrients. Therefore, supplement users were more likely to meet their Daily Reference Intakes (DRIs) both from only their food, and from their food and supplements. However, supplement users also experienced a higher risk of excessive nutrient intakes.
