Calcium and Phosphorus: side effects, safety & interactions

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.

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.

Safety

Phosphorus: side effects, safety & interactions

Excess phosphate is harmful in kidney disease and may affect bone/vascular health generally. Don't supplement without a

Swap the two

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.

None — every outcome it grades is graded in both.

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.
