Effects of potassium supplements on glucose metabolism in African Americans with prediabetes: a pilot trial

Low potassium has been identified both as a risk factor for type 2 diabetes and as a mediator of the racial disparity in diabetes risk. Low potassium could be a potentially modifiable risk factor, particularly for African Americans. We sought to determine the effects of potassium chloride (KCl) supplements, at a commonly prescribed dose, on measures of potassium and glucose metabolism. Among African-American adults with prediabetes, we conducted...
