What is Calcium?
Calcium, as we all know, is one of the most important mineral needed by the human body. Not only is it vital for the growth and maintenance of healthy teeth and bones but also facilitates muscle contraction, nerve signaling and secretion of certain hormones and enzymes. This mineral plays an important role in human metabolism, constituting about 1 to 2 % of an adult human’s body weight. It helps to manage the acid and base balance in our blood stream. Nearly 99% of the calcium in our body is found in our bones and teeth. The table given below shows the recommended daily intake of calcium for people of different age groups.
The amount of calcium you need every day depends on your age and gender:
Women | |
Age 50 & younger | 1,000 mg* daily |
Age 51 & older | 1,200 mg* daily |
Men | |
Age 70 & younger | 1,000 mg* daily |
Age 71 & older | 1,200 mg* daily |
*This includes the total amount of calcium you get from various foods and supplements.
Each day we lose some amount of calcium through our nails, skin, hair, sweat, urine and faeces. Our bodies cannot produce new calcium and this requirement is fulfilled by extracting calcium from our bones. This adversely affects bone density causing the bones to become soft and weak. This increases the risk of fractures and osteoporosis. Deficiency of calcium can lead to health issues like muscle cramps, loss of appetite, lethargy, convulsions, numbness in fingers and toes and abnormal heart rhythms. Thus, the best way to fulfill this deficiency is to increase the intake of foods that are rich in calcium.
