NOW Calcium Hydroxyapatite
Calcium as microcrystalline hydroxyapatite (MCHA) from bovine bone matrix — commonly ~500 mg elemental calcium and ~200 mg phosphorus per 2-capsule serving. Shortlisted so the bone-matrix form is named, not marketed as a clinic. Bovine source; not a vegetarian lane.
Affiliate link via /go/cal-now-hydroxy (ASIN B000I4DLJK). Prefer Amazon.com or the brand-authorized seller. Serving is often two capsules — verify elemental calcium and phosphorus on the live label. Not medical advice.

Listing snapshot
Why it is on the shortlist
MCHA is a different salt family from citrate and carbonate. Naming it keeps the shortlist honest. Map: Calcium. Kitchen carbonate powder: NOW carbonate powder.
Boundaries
This is still food-second calcium — dairy and calcium-set tofu come first. Phosphorus on the label is part of the matrix, not a reason to add a separate phosphorus capsule. Seller bone-health copy stays on Amazon. Bone density is an index, not a clinic.
