Nutrient Recommendations and Databases – Office of Dietary Supplements

Summary

This resource, maintained by the NIH Office of Dietary Supplements, consolidates authoritative US Dietary Reference Intake values established by the National Academies of Sciences, Engineering, and Medicine, covering essential vitamins, minerals, and macronutrients across different age, sex, and physiological groups. It serves as a primary reference for researchers, clinicians, and policymakers seeking standardised intake benchmarks for dietary assessment and intervention design. The accompanying databases support nutrient intake analysis relative to established thresholds, making it a foundational tool in nutritional epidemiology and public health nutrition.

UK applicability

Although the DRI values are US- and Canadian-specific, they are broadly comparable to UK Dietary Reference Values (DRVs) set by the Scientific Advisory Committee on Nutrition (SACN), and are widely used internationally as reference benchmarks. UK researchers and practitioners should cross-reference with SACN guidance and the British Nutrition Foundation's DRV resources for UK-specific application.

Key measures

Dietary Reference Intakes (RDA, AI, UL, EAR) by nutrient and life-stage group; nutrient composition databases

Outcomes reported

This resource compiles and presents Dietary Reference Intakes (DRIs), including Recommended Dietary Allowances (RDAs), Adequate Intakes (AIs), Tolerable Upper Intake Levels (ULs), and Estimated Average Requirements (EARs) for vitamins, minerals, and macronutrients across population groups. It also provides access to associated nutrient databases used to support dietary assessment and policy guidance.
