gluconic acid Gluconic acid is an organic compound with molecular formula C6H12O7 and condensed structural formula HOCH2(CHOH)4CO2H. A white solid, it forms the gluconate anion in neutral aqueous solution. The salts of gluconic acid are known as "gluconates" ...

. It is also referred to as 2,3,4,5,6-pentahydroxycaproic acid potassium salt, D-gluconic acid potassium salt, or potassium D-gluconate. It contains 16.69% elemental potassium by mass. Thus 5.99 g of potassium gluconate contains 1 g of potassium. It has a density of 1.73 g/cm³.

Dietary uses

Potassium gluconate is used as a mineral supplement and sequestrant. It is sold over-the-counter as tablets or capsules providing up to 593 mg of potassium gluconate, thereby containing 99 mg or 2.53 milliequivalents of elemental potassium. This is the permissible upper limit for each tablet or capsule of over-the-counter potassium supplements sold in the US. Potassium gluconate is also sold over-the-counter as bulk powder. As a
