Potassium is a mineral of great importance to the body. The adult RDA for potassium at 4,700 mg (the equivalent of 13 half-cup servings of fruits and vegetables a day) is nearly four times that of calcium (at 1,200 mg). While it is widely known that potassium serves along with sodium to maintain critical fluid balance within the body, its role in bone health is less well appreciated. The role of potassium in bone health relates to the ability of selected potassium salts to neutralize bone-depleting metabolic acids. If these mineral salts are not consumed in the diet in adequate amounts, alkalizing mineral compounds are drawn from the bone to help reduce the acid state.
