Potassium orotate capsules, manufactured by Atrium, Inc., provide 99 milligrams elemental potassium combined with 401 milligrams orotic acid. Orotates are the mineral salts of orotic acid, a substance found in the body and in a number of foods, whose use was developed by the German physician Hans Nieper. Orotic acid acts as a mineral carrier, which may provide improved delivery of minerals throughout the body compared to other mineral compounds.
