Scoring criteria

Quantity
100 / 100
The labeled routine provides 600 mg calcium, 200 mg magnesium, and 50 mcg vitamin D3 daily, which is a reasonable supplemental maintenance amount for the stated bone-support role.
Form
65 / 100
Vitamin D3 is identified, but the calcium and magnesium chemical forms are not disclosed, leaving their comparative absorption and tolerability unresolved.
Convenience
49.5 / 100
The labeled routine is two capsules twice daily, and the container holds 120 capsules.
Label accuracy
75 / 100
The published panel is internally consistent, although it does not identify the calcium or magnesium forms.
Formula balance
75 / 100
The formula combines relevant bone nutrients without a clearly established compatibility problem at the labeled amounts, although its broader vitamin additions are not specifically targeted.
Purity
75 / 100
The label lists ordinary excipients and provides no product-specific contamination or quality-control evidence.
Cofactors
50 / 100
Boron and the declared B-vitamin amounts have complementary nutritional roles, but meaningful added bone benefit beyond the principal nutrients is uncertain.
