Category average: 57.7 / 100

A reasonable magnesium amount comes with only 99 mg of potassium per serving, so this is a modest potassium contribution rather than a substantial source of both minerals.

Scoring criteria

Quantity
50 / 100
The evaluated routine provides a reasonable 250 mg of magnesium but only 99 mg of potassium, a small contribution for a formula presented as magnesium and potassium supplementation.
Form
75 / 100
The identified magnesium and potassium aspartate forms have no established relevant absorption or tolerability advantage over ordinary alternatives.
Convenience
85 / 100
Use one serving of two capsules once daily: it provides 250 mg magnesium and 99 mg potassium, while two daily servings would provide 500 mg supplemental magnesium, above the U.S. adult supplemental UL of 350 mg.
Label accuracy
100 / 100
The stated mineral amounts and directions are internally consistent, with no established contradiction or misleading claim.
Formula balance
75 / 100
The two mineral forms are an ordinary combined formula, with no established compatibility issue or distinctive balance advantage.
Purity
75 / 100
The ingredients and excipients are listed, but the GMP statement alone does not establish product-specific purity controls.
Cofactors
0 / 100
The 100 mg of taurine is quantified but does not establish a meaningful complementary benefit at this amount.
