The U.S. Food and Drug Administration (FDA) developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet. The DV for potassium is 4,700 mg for adults and children age 4 years and older //

Mild hypokalemia is characterized by constipation, fatigue, muscle weakness, and malaise //

Magnesium depletion can contribute to hypokalemia by increasing urinary potassium losses [1,33,34]. It can also increase the risk of cardiac arrhythmias by decreasing intracellular potassium concentrations. More than 50% of individuals with clinically significant hypokalemia might have magnesium deficiency //

Kidney stones are most common in people aged 40 to 60 [52]. Stones containing calcium—in the form of calcium oxalate or calcium phosphate—are the most common type of kidney stone. Low potassium intakes impair calcium reabsorption within the kidney, increasing urinary calcium excretion and potentially causing hypercalciuria and kidney stones [16,37]. Low urinary levels of citrate also contribute to kidney stone development. //

there is no evidence that high intakes of potassium cause hyperkalemia in adults with normal kidney function or other adverse effects. Therefore, the committee did not set a UL for potassium.
