What Happens When You Have a Calcium Deficiency?

Calcium deficiency, which is clinically known as hypocalcemia is a condition in which the calcium intake is lower than the amount of calcium required by the body. Calcium is ingested through the food we eat. Calcium deficiency is a common condition with some estimates stating that more than 3 billion people in the world are suffering from this condition.

Why Does the Body Need Calcium?

Calcium plays a vital role in the body. Some major functions of calcium are:

  1. Bone Development: Calcium is an essential component of bone development and maintenance. Children require a large amount of calcium during their growing period.

  2. Contraction of Muscles: Calcium plays a major role in the contraction of muscles.

  3. Functions of the Cardiovascular system: Calcium helps in the formation of blood clots and also plays a direct role in the functioning of the heart muscle.

There are various studies which link calcium to other important functions including lowering blood pressure and maintaining dental health.

How Much Calcium Do I Need?
