Pure Encapsulations Potassium Magnesium (Aspartate), 90 Capsules

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.

The aspartate forms are conventional mineral forms with no established comparative absorption or tolerability advantage for this use.

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.

The matched high-confidence panel gives consistent per-capsule amounts and serving directions, with no evident contradiction.

The paired mineral formula has no evident compatibility concern at the labelled amounts, and no specific synergistic advantage is established.

The listed excipients are ordinary, and no product-specific testing or contaminant information supports a higher or lower mark.

Both minerals are co-primary ingredients, so neither qualifies as a separately supporting cofactor.
