Product score

80.2 / 100Very good

Category average: 75.4 / 100

This is a broad bone-support formula providing a useful calcium-hydroxyapatite base with vitamin D, vitamin K, magnesium, and other minerals, although its capsule routine is substantial.

Scoring criteria

Quantity
100 / 100
The labelled four-capsule routine provides a reasonable supplemental bone-support amount of calcium, hydroxyapatite, vitamin D, vitamin K, magnesium, and phosphorus.
Form
75 / 100
Microcrystalline hydroxyapatite is a recognized calcium-phosphate form relevant to bone support, but it has no clearly established substantial practical advantage over ordinary calcium forms.
Convenience
49.5 / 100
The label directs four capsules daily, taken in one or two divided doses, and provides 60 servings of 4 capsules.
Label accuracy
100 / 100
The quantified ingredients and serving directions are internally consistent with the published high-confidence label.
Formula balance
80 / 100
The formula covers calcium-phosphate bone mineral and several relevant supporting nutrients at useful amounts, without a clear formulation mismatch.
Purity
75 / 100
The product states manufacture in a GMP facility, but it provides no specific independent contaminant or identity testing evidence.
Cofactors
75 / 100
The declared vitamin D, vitamin K, magnesium, phosphorus, and trace minerals provide meaningful complementary support for bone metabolism.
