Sources: Sources of dietary potassium can be found in the consumption of green leafy vegetables. Wheat germ, milk products, lean meats, potatoes and beans, bananas, and oranges are an excellent source of potassium.

Importance for the human body: Potassium plays an integral role in the human body in controlling the water balance of the body. Potassium works in conjunction with sodium in order to keep water levels in the body consistent. Potassium keeps muscle and nerve activity normal by helping in the proper functioning of nerve impulses and the contraction of all muscle in the human body. Potassium also helps to maintain a regular, normal heart rhythm. Potassium’s other essential function in the human body is to store carbohydrates which then are broken down for energy.

Deficiency: Potassium deficiency occurs because potassium levels in foods are often decreased due to the processing methods of most manufactured food products. It’s first deficiency symptom is muscle disorder or muscle weakness and fatigue. Sufferers of potassium deficiency may also experience symptoms such as dizziness and mental confusion. In extreme cases, the starvation of potassium sources in the human body can cause impairment of nerve and muscle functions which results in abnormal heart rhythms. Additionally, potassium deficiency can cause the musculoskeletal system to essentially freeze up therefore constricting the bowl and causing constipation.

Recommended intakes of potassium vary, but the common agreement among professionals seems to be that between 4 and 6 grams of potassium a day will prevent deficiency. Typically, potassium levels in the blood are regulated by the kidneys and any excess potassium is eliminated in the urine. However, excess potassium can cause severe muscular paralysis and heart rhythm deficiencies. Of course, before starting any form of supplementation you should consult your health care practitioner.
