90.3 / 100Excellent

This is a reasonably dosed two-mineral formula when taken as two capsules daily, but its potassium contribution remains modest.

Scoring criteria

Quantity
100 / 100
Two capsules provide a reasonable maintenance amount of magnesium and a meaningful modest supplemental amount of potassium for general adult use.
Form
85 / 100
The minerals are supplied as aspartate salts, with magnesium aspartate offering a recognized organic-salt absorption advantage over poorly absorbed inorganic forms without guaranteeing superior clinical results.
Convenience
76.5 / 100
Two capsules daily, taken as one capsule with two meals, provide 140 mg magnesium and 198 mg potassium while remaining below the adult supplemental magnesium UL.
Label accuracy
100 / 100
The matched label gives consistent serving, container, magnesium, potassium, and ingredient information without an established contradiction.
Formula balance
75 / 100
The two minerals are compatible in this formula, but no strong evidence establishes a clinically meaningful added benefit from their combination or the aspartate ligand.
Purity
75 / 100
The label shows a simple capsule formulation with no documented contaminant or additive concern, but it provides no product-specific testing evidence.
Cofactors
0 / 100
There is no separately declared non-principal cofactor with an established complementary role.
