Score before rubric limits: 81.5 / 100.

Scoring criteria

  • Quantity

    100 / 100

    The labelled routine supplies substantial magnesium and meaningful calcium with complementary vitamin D3 and zinc for the stated general nerve and bone role.

  • Form

    65 / 100

    The label identifies the minerals but does not disclose their chemical forms, leaving relevant absorption and tolerability properties unresolved.

  • Convenience

    70 / 100

    The label directs three tablets daily, while divided dosing is preferred rather than required, and the package states 250 tablets.

  • Label accuracy

    100 / 100

    The supplied panel is internally consistent about the listed serving amounts and directions, with no established principal-dose contradiction.

  • Formula balance

    75 / 100

    The formula combines relevant nutrients without a demonstrated compatibility problem, although the high magnesium exposure makes the overall balance less clearly advantageous.

  • Purity

    75 / 100

    The product lists ordinary excipients and provides no product-specific contaminant or manufacturing-control evidence that warrants a higher or lower mark.

  • Cofactors

    75 / 100

    Vitamin D3 and zinc are declared at meaningful amounts and have established complementary roles in bone-related physiology.
