Scoring criteria

Quantity
100 / 100
At four capsules, 280 mg magnesium and 396 mg potassium make a useful general supplemental amount for this paired formula, without implying replacement of dietary potassium.
Form
75 / 100
The aspartate forms are conventional mineral forms with no established comparative absorption or tolerability advantage for this use.
Convenience
49.5 / 100
The label permits one capsule 1–4 times daily; four capsules provide 280 mg magnesium and 396 mg potassium, with magnesium below the US adult supplemental UL of 350 mg.
Label accuracy
100 / 100
The matched high-confidence panel gives consistent per-capsule amounts and serving directions, with no evident contradiction.
Formula balance
75 / 100
The paired mineral formula has no evident compatibility concern at the labelled amounts, and no specific synergistic advantage is established.
Purity
75 / 100
The listed excipients are ordinary, and no product-specific testing or contaminant information supports a higher or lower mark.
Cofactors
0 / 100
Both minerals are co-primary ingredients, so neither qualifies as a separately supporting cofactor.
