Calcium is one of the most important nutrients in the body. The main role of calcium is to build and maintain a strong skeletal system. 

In addition, calcium is also important for muscle contraction, blood pressure regulation, nerve transmission and blood clotting.

Over 99 percent of the body’s calcium is found in bones and teeth. However, our bodies cannot produce their own calcium and must get it from food.

However, many people have unbalanced eating habits which can easily cause a calcium deficiency.

Moreover, the rate of bone loss continues to accelerate with age. Over time, calcium deficiency can lead to a “bone crisis.”

Therefore, it’s important to add calcium-rich foods to your diet, to make your bones strong.
