Vitamin D and Kidney Disease
Why vitamin D levels matter in kidney disease, and how it is managed.
Last updated: 2026-09-24
The kidneys activate vitamin D, so kidney disease often causes low active vitamin D, affecting bones.
Management
If levels are low, a doctor may prescribe the active form of vitamin D — do not self-supplement.
