Calcium is the most abundant mineral in our body and is involved not only in bone and teeth formation, but also in cardiac function, muscle contraction and other important functions. Adequate calcium can be supplied by daily foods, such as milk, yogurt, cheese, tofu, almonds, sardines, broccoli and oranges. For example, one 8 ounce glass of milk contains about 300mg of calcium. Calcium supplementation, however, may be required if you do not eat those calcium-rich foods regularly, especially if you are lactose intolerant.

Calcium supplements come in many different salt forms, including citrate, carbonate and gluconate. They contain different amounts of elemental calcium. For example, 600mg of calcium citrate only contains 126mg of the elemental calcium. Therefore, you should check the type of calcium salt when you choose your calcium supplement products. Calcium carbonate, for example, contains more elemental calcium but has to be taken with food for better absorption. Taking a calcium product with vitamin D will improve absorption.

Adequate calcium in the body is extremely important for your health. Having enough calcium may prevent many diseases and discomforts, such as osteoporosis and arthritis. If you have any questions about calcium, talk to your pharmacist.
