Scoring criteria

Quantity
100 / 100
The labelled 750 mg daily calcium serving is within a reasonable supplemental maintenance range for general adults.
Form
75 / 100
The product combines ordinary calcium carbonate with bone-meal hydroxyapatite, without an established broad practical advantage over standard calcium forms.

The label directs one 2.8-gram measured teaspoon daily, and the container provides 162 servings.
Label accuracy
100 / 100
The matched panel gives internally consistent serving, mineral, and container quantities without an established contradiction.
Purity
75 / 100
The label lists no unnecessary additives, but it provides no product-specific contaminant or quality-control evidence.
Cofactors
50 / 100
The declared 250 mg phosphorus provides a meaningful complementary bone-mineral role, while the 5 mg magnesium is token.
