Potassium gluconate is the potassium salt of the conjugate base of gluconic acid. 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% potassium by mass. Thus 5.99 g of potassium gluconate contains 1 g of potassium.
It has a density of 1.73 g/cm3.
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 mEq 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.
