Dietary deficiency of potassium frequently goes undiagnosed because the element is ubiquitous in fruits and vegetables, and symptoms are generally vague and non-specific. Consuming a diet high in processed foods and sodium, can easily result in a mild or chronic Potassium deficiency called hypokalemia. Having too much potassium in the blood is called hyperkalemia.

Potassium is an  electrolyte and conducts electricity in the body, along with sodium, chloride, calcium, and magnesium. Potassium is crucial to heart function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function.
