Experts at the University of Florida say that 16 key minerals are essential for human biochemical processes: Potassium What it does - a systemic affects entire body electrolyte, essential in co-regulating ATP an important carrier of energy in cells in the body, also key in making RNA with sodium. Deficiency - hypokalemia - can profoundly affect the nervous system and heart. Excess - hyperkalemia - can also profoundly affect the nervous system and heart.

Chloride What it does - key for producing stomach acid, important in the transport of molecules between cells, and vital for the proper functioning of nerves. Deficiency - hypochloremia - low salt levels, which, if severe, can be very dangerous.

Excess - hyperchloremia - usually no symptoms, linked with excessive fluid loss. Sodium What it does - a systemic electrolyte, and essential in regulating ATP with potassium.

Important for nerve function and regulating body fluid levels. Deficiency - hyponatremia - causes cells to malfunction; extremely low sodium can be fatal. Excess - hypernatremia - can also cause cells to malfunction, extremely high levels can be fatal. Calcium What it does - important for muscle, heart, and digestive health.

Excess - hypermagnesemia - nausea, vomiting, impaired breathing, low blood pressure. Very rare, but may occur if patient has renal problems. Zinc What it does - required by many enzymes.
