Potassium is the third most abundant mineral in the human body. The importance of potassium should not be underestimated as it is required to keep the heart, brain, kidneys, muscle tissue, and other important organ systems of the body in good condition. Low potassium can be associated with an increased risk of hypertension, stroke, kidney stones, carbohydrate intolerance, osteoporosis, heart disease, cancer, arthritis, digestive disorders, and even infertility.
