Full Answer

WebMD explains that potassium is important in nerve signal transmission, fluid balance, muscle contractions and numerous chemical reactions. Some people use this mineral for treating infant colic, insulin resistance, thallium poisoning, Meniere’s disease, high calcium levels and symptoms of menopause. Additionally, people use it to treat headaches, allergies, alcoholism, acne and Alzheimer’s disease among other diseases and conditions. Health care providers treat and prevent low potassium levels, heart attack and irregular heartbeats by supplying potassium intravenously to a patient.

Potassium is also possibly effective for lowering high blood pressure and preventing stroke, says WebMD. It lowers systolic blood pressure and diastolic blood pressure. It is most effective among people with low potassium levels or high daily sodium intake. Potassium derived from food sources, not supplements, potentially helps prevent high blood pressure. This mineral likely decreases the risk of stroke, medical evidence suggests. Some studies reveal that foods providing at least 350 mg of potassium in each serving help reduce risks of stroke. Food sources of potassium include fruits, vegetables, milk, beans and cereals.
