Over half of US adults and one-third of children take at least one dietary supplement. Combined with intakes of foods, total nutrient intake can be estimated and linked to health outcomes in etiologic research. Such population data can inform guidance, such as the Dietary Guidelines for Americans and Dietary Reference Intakes. Supplements may be warranted for sub-groups where nutritional requirements may not be met through diet alone. ODS’s Recommendation: 2-4 dietary recalls and 1 FFQ per year.
