These impulses use the nervous system as the transmission lines. The nervous system, like a telephone line, carries messages to and from the brain. The minerals are the switches that allow the electric impulses to flow without disruption or disturbance. Minerals are engaged in almost every physical contraction in the body. You could not breathe, eat or drink without the aid of minerals.
Minerals are absolutely for health.
Other functions of calcium include its influence in blood coagulation, neuromuscular excitability, cellular adhesiveness, transmission of nerve impulses, maintenance and function of cell membranes and activation of enzyme reactions and hormone secretion. When calcium levels in the blood are abnormally low, hypocalcemia can occur. Some symptoms of hypocalcemia are tetany, increased neuromuscular irritability, seizures and cardiac cramps. Low levels of calcium can also lead to reduced skeletal mass. Calcium absorption is dependent on the amount of exposure a person has to ultraviolet light, vitamin D intake, the sex and age of the individual and the bio-availability of calcium.
