Scoring criteria

Quantity
100 / 100
Two tablets provide approximately 283 mg elemental magnesium, which is a reasonable maintenance supplemental dose for general adults.
Form
85 / 100
Magnesium malate is an organic magnesium salt with generally better solubility and tolerability than ordinary magnesium oxide, although it is not a uniquely proven superior form.
Convenience
85 / 100
Two of the labelled one-to-three tablets provide about 283 mg elemental magnesium once daily with meals, reaching a reasonable supplemental amount while remaining below the U.S. supplemental magnesium UL.
Label accuracy
100 / 100
The high-confidence FDA-matched label gives internally plausible elemental magnesium and magnesium malate amounts for the three-tablet serving.
Purity
75 / 100
The label discloses ordinary excipients and provides no product-specific contaminant or independent quality-control evidence.
Cofactors
0 / 100
The separately listed malic acid has no clearly established added benefit for general magnesium supplementation at this declared amount.
