Vitamin D + Calcium: work well together and Calcium
Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.
Interaction
Vitamin D + Calcium: work well together
D improves calcium absorption; the bone benefit needs both.
Grade C0 graded outcomesrevised Jul 10, 2026
Assembled by the app from other entries in this library. It adds no evidence of its own — follow the links to the entries it draws on.
Compound or practice
Calcium
Food-first for bone; the supplement matters mainly when dairy is out — and megadosing may not be free of cardiovascular cost.
Grade B2 graded outcomesrevised Jul 10, 2026
A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.
Graded in both
Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.
No outcome has the same name in both entries. They may still overlap under different wording — read the two lists below.
Graded only in Vitamin D + Calcium: work well together

Both columns are read from the entries as they stand in this library. A comparison is not advice to take either one, and it is no substitute for a clinician who knows the person.
