A straightforward magnesium-malate tablet with a meaningful supplemental amount at two tablets daily; the label also permits a three-tablet routine that exceeds the U.S. supplemental magnesium UL.

Scoring criteria

Quantity
100 / 100
Two tablets provide about 283 mg elemental magnesium, a reasonable supplemental amount for the stated general role.
Form
75 / 100
Magnesium malate is a conventional organic magnesium salt, with no established practical absorption or tolerability advantage warranting a premium mark.
Convenience
85 / 100
The label allows 1–3 tablets daily; two tablets provide about 283 mg elemental magnesium, a reasonable supplemental amount below the U.S. adult supplemental UL of 350 mg.
Label accuracy
100 / 100
The listed 425 mg magnesium per three-tablet serving is broadly consistent with the stated 3.75 g magnesium malate trihydrate.
Purity
75 / 100
No product-specific purity testing or quality-control evidence is provided, so ordinary quality remains unresolved.
Cofactors
0 / 100
The separately listed malic acid has no established complementary role at this amount for general magnesium supplementation.
