Category average: 68.3 / 100
Average for similar products: 63.8 / 100

A reasonable magnesium amount, but the potassium contribution is small for the stated combined-mineral role. The evaluated routine is 2 capsules once daily; the label's twice-daily option would exceed the adult supplemental magnesium UL.

Scoring criteria

Quantity
50 / 100
At the selected routine, magnesium is 250 mg, while potassium is only 99 mg, a clearly small contribution for a formula intended to provide both minerals.
Form
75 / 100
The title identifies magnesium and potassium as aspartates, conventional mineral forms with no clear, established practical advantage over ordinary alternatives for this use.
Convenience
85 / 100
The lowest labelled routine is 2 capsules once daily; this provides 250 mg magnesium, below the US adult supplemental magnesium UL. The twice-daily option would provide 500 mg magnesium, so it is not selected.
Label accuracy
100 / 100
The matched label gives consistent amounts and directions, with no evident contradiction or misleading completeness claim.
Formula balance
75 / 100
The combined mineral formula has no established compatibility advantage or defect beyond the potassium shortfall assessed under quantity.
Purity
75 / 100
The listed excipients are ordinary, and no product-specific purity testing or defect is established by the supplied information.
Cofactors
0 / 100
Taurine is separately quantified at 100 mg, but that is not a meaningful complementary amount for this role.
