Potassium malate is the dipotassium salt of malic acid (CAS 585-09-1; C4H4K2O5, MW 210.27), recognised as food additive E351. As an organic-acid salt it delivers about 37% elemental potassium, above the gluconate and orotate but below the inorganic chloride, sulfate and phosphate salts of the family. It is freely water-soluble and near-neutral in reaction, which separates it from the alkaline carbonate and bicarbonate forms. We manufacture it as a white to off-white powder in tablets, capsules and powder blends.
