The bodies needs potassium for correct cellular, tissue and organ functioning. Potassium plays a key role in being an electrolyte and an electrical conductor. This helps muscles to contract correctly. The muscle conducting abilities means that potassium also plays an important role in heart health. A deficiency of potassium may lead to congestive heart failure and arrhythmias. Potassium influences sodium levels and this may help to lower blood pressure.
Another symptom of potassium deficiency is muscle cramping and muscle fatigue.
