Potassium

Potassium is a mineral that must be obtained in the diet and is required for life. It is one of the seven essential “macrominerals” that need to be provided by the diet in quantities of at least 100 milligrams per day.

Potassium is an electrolyte, which are minerals that conduct electrical impulses throughout the body, including in nerves, muscle, and cardiac conduction tissue.

Potassium deficiency, known as hypokalemia, is relatively common, and can occur under a variety of different conditions. Deficiency can result in fatigue, muscle symptoms (cramping, spasms, weakness), gastrointestinal symptoms (nausea, vomiting, constipation), and cardiac symptoms (arrhythmia, sudden death).

Potassium is not expected to be of specific utility in the treatment of ASD.

Potassium is supplemented in a wide variety of conditions including cardiovascular and gastrointestinal disorders, infertility, diuretic use, extreme exercise, and eating disorders.

Too much potassium can result in hyperkalemia, a potentially dangerous condition that can include abnormal heart rhythms.

Laboratory testing can reveal the presence of a deficiency of this nutrient, as often can an EKG.
