Summary
This resource, produced by the National Institutes of Health Office of Dietary Supplements (NIH ODS), comprises a library of individual fact sheets summarising peer-reviewed evidence on vitamins, minerals, and other dietary supplements. Each fact sheet covers nutritional functions, dietary sources, intake recommendations, deficiency and toxicity risks, and evidence for health outcomes. The library serves as a reference tool for researchers, clinicians, and policymakers rather than presenting original empirical research.
UK applicability
Although produced by a US federal agency and referencing US dietary reference values, the underlying nutritional science is broadly applicable to UK practice; UK users should cross-reference with NHS and SACN guidance where recommended intake levels differ from US standards.
Key measures
Recommended dietary allowances (RDAs); tolerable upper intake levels (ULs); nutrient bioavailability; prevalence of deficiency; supplement usage rates
Outcomes reported
The library provides summaries of scientific evidence on the composition, physiological roles, health effects, recommended intakes, and safety of individual dietary supplements and nutrients. Each fact sheet reports on deficiency risks, upper tolerable intake levels, and interactions with medications or health conditions.
