This directory lists selected official guidance, scientific assessment bodies and research resources relevant to nutrition and food supplements. They are used according to their remit and do not endorse Nutri-MiAmo. A source directory is not a claim that every organisation has reviewed or approved this service.
How evidence is interpreted: WHO guidelines are informed by systematic reviews and a structured assessment of benefits, harms, certainty, values and implementation. A university affiliation or a single experiment does not by itself establish a recommendation. Individual studies are assessed by design, registration, risk of bias, applicability, consistency and conflicts of interest. Trial registries help locate studies; registration alone is not proof of efficacy.
International guidance and evidence methods
Research literature and clinical trial records
Peer-reviewed university and hospital research is considered study by study. Searches may use PubMed, Cochrane, ClinicalTrials.gov, WHO ICTRP, EU CTIS and NIHR resources. A registry entry is not an independent assessment of a study, and a university name is not a substitute for critical appraisal.
Directory reviewed: 31 October 2026. Links identify selected sources relevant to the current scope; this is not an exhaustive list of every public authority, university or research institution. Recommendations and clinical thresholds must be traced to the specific source, population, context, publication date and evidence assessment that supports each rule.
