Potassium

Potassium is one of the key macrominerals required by the body to maintain its normal daily functions. Potassium is essential to regulating the water balance within the body and its cells and is also essential to the healthy functioning of the brain, heart, muscles and kidneys. Potassium keeps the heat beating normally, helps the muscles to contract, and feeds the cells by controlling the transfer of nutrients from surrounding fluids. It helps the kidneys remove wastes products from the body, works with phosphorus to supply oxygen to the brain, and cooperates with calcium to regulate the nerves. 

Precautions

In most individuals, excess potassium intake is either excreted or stored in the intestines as a reservoir for future use. If you are taking large quantities of shark cartilage decrease your intake of supplements of certain minerals such as magnesium and potassium to maintain proper balance.
