This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
Thirty pages cover 10–150 nmol/L with paired ng/mL, clearly separating severe deficiency definitions, bone-health adequacy, assay variation and thresholds promoted without consensus. Each section states which authority uses which boundary, why more is not always better, and that a result plus medical context belongs with a clinician; it never generates a loading dose.
How to use it
Use Vitamin D blood values across units and disputed thresholds as an index across related cases. The consolidated page establishes the shared method first; narrower pages should appear only when they can add case-specific data rather than repeat a template.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.
| Language | Example phrase |
|---|---|
| Estonian | D vitamiin 45 nmol madal |
| Finnish | D-vitamiini 45 nmol/l |
| Russian | витамин D 18 нг мл что значит |
| English | vitamin D 45 nmol to ng ml |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.

Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
Scope and boundaries
/rda asks how much vitamin D to consume; these pages explain one laboratory result and the lack of one universal “optimal” number.
