Empiric vitamin D supplementation is recommended for children/adolescents (1-18 years), adults ≥75 years, pregnant individuals, and those with high-risk prediabetes to prevent specific adverse outcomes, whereas supplementation beyond Dietary Reference Intakes (DRI) is not recommended for healthy adults under 75.

If you are pregnant, over 75, have high-risk prediabetes, or are a child/teen, take daily vitamin D (typically 600-3500 IU depending on group) via food or supplements. If you are a healthy adult under 75, stick to the standard Dietary Reference Intake (600-800 IU) and do not test your levels or take extra doses, as there is no evidence it prevents disease in you.

ModerateQualifiesMEDIUM confidence
The panel suggests empiric vitamin D supplementation for children and adolescents aged 1 to 18 years... for those aged 75 years and older... for those who are pregnant... and for those with high-risk prediabetes... The panel suggests against empiric vitamin D supplementation above the current DRI to lower the risk of disease in healthy adults younger than 75 years.
