Category average: 76 / 100
Average for similar products: 88.3 / 100

A straightforward, adequately dosed magnesium supplement at two capsules daily, though the label does not identify its magnesium form and the routine slightly exceeds the U.S. supplemental UL.

Scoring criteria

Quantity
100 / 100
The labelled 400 mg per daily serving is a reasonable supplemental amount for general magnesium support; the mineral amount is treated as elemental under the usual Supplement Facts convention.
Form
65 / 100
The label identifies magnesium but not its chemical form, leaving form-dependent absorption and gastrointestinal tolerability unresolved.
Convenience
85 / 100
The fixed direction is two capsules once daily, and the package provides 250 servings of two capsules.
Label accuracy
100 / 100
The 400 mg serving amount and 200 mg title amount are consistent with two capsules per serving, with no identified label contradiction.
Purity
75 / 100
No product-specific purity testing or contaminant information is supplied, and no concrete defect is established.
Cofactors
0 / 100
No separately quantified complementary supporting ingredient is declared.
