Category average: 76 / 100
Average for similar products: 78.7 / 100

A straightforward magnesium supplement with a reasonable one-tablet routine, but the label does not identify its magnesium forms and the added B6 has no clearly established complementary benefit for general magnesium supplementation.

Scoring criteria

Quantity
100 / 100
The selected 200 mg magnesium routine is a reasonable supplemental maintenance amount for general adult use.
Form
65 / 100
The panel identifies magnesium but not its salt forms, leaving the relevant absorption and tolerability properties unresolved.
Convenience
100 / 100
The directions allow 1 or 2 tablets daily; one tablet provides 200 mg magnesium and is the smallest allowed routine that is reasonable for supplemental maintenance.
Label accuracy
100 / 100
The label clearly states the two-tablet serving amounts and directions, with no evident contradiction.
Purity
75 / 100
No product-specific purity controls or contaminant evidence are supplied, so purity remains ordinary and unresolved.
Cofactors
0 / 100
Vitamin B6 provides 15 mg at the selected dose, but the label does not establish a meaningful complementary benefit for general magnesium supplementation.
