Calcium is not only beneficial in the development of strong bones and teeth, but also helps in the proper functioning of muscles and nerves. Calcium is also known to assist in blood clotting and keeping the heart healthy. The main reason for fragile bones (especially) in older people is, when the body does not get the required calcium it begins to supplement its calcium needs by drawing calcium from the bones.

The daily requirement of calcium can be met by consuming diary products and vegetables such as broccoli, grains such as oats and every form of nuts. A natural calcium supplement is coral calcium. Coral calcium is the salt of calcium obtained from fossilized coral reefs. Coral calcium is also rich in magnesium and other trace minerals.

Calcium as a vitamin needs to be metabolized and to assist in calcium metabolism one should also take vitamin D supplements to ensure the proper absorption of calcium.

The daily requirement of calcium in adults is between 1000 to 1300 mg per day. Since it is quite difficult to achieve this requirement through a normal diet, calcium supplements are a viable option. Some of th best calcium supplements are-calcium citrate, calcium carbonate, oyster shell or bone meat based calcium supplements.
