Scoring criteria

Quantity
100 / 100
Three capsules provide approximately 212.5 mg elemental magnesium, which is a reasonable maintenance supplemental amount for general adults.
Form
75 / 100
Magnesium malate is a recognized organic magnesium salt with no established major practical advantage over ordinary well-tolerated magnesium forms.
Convenience
70 / 100
Three capsules provide approximately 212.5 mg elemental magnesium, the smallest labelled routine reaching a reasonable supplemental amount.
Label accuracy
100 / 100
The matched label clearly distinguishes 425 mg elemental magnesium per six-capsule serving from 2.5 g malic acid.
Purity
75 / 100
The label lists ordinary capsule excipients without documented contamination controls or product-specific purity evidence.
Cofactors
50 / 100
The declared malic acid may provide a complementary role, but meaningful added benefit beyond supplying magnesium is uncertain.
