Potassium

The body uses potassium for maintaining a regular heartbeat and keeping the nerve system healthy. A deficiency in this mineral can result in body fatigue, acne, dry skin, insomnia, impaired reflexes and an irregular heartbeat. Potassium also assists the body in some important _meta_bolic processes. It works with sodium to regulate the body's water balance and helps maintain stable blood pressure. Stress can increase the body's potassium requirements.
