Calcium is the most abundant mineral in the body and it plays a crucial role in maintaining physical strength and vitality. Without adequate levels, we become frail, vulnerable to the bumps and bruises of a healthy, active life. However, calcium supplements can help restore strength to your bones and protect the long-term health of you and your family.

Ninety-nine percent of the body's calcium is found in the skeletal structure. Our bones not only support us, but they act as calcium banks, providing a reserve of the mineral in case blood calcium levels drop. Our bodies know it's essential to maintain adequate blood calcium. When our diets are calcium-deficient, the mineral must be taken from our bones. Over time, loss of calcium from the bones can lead to osteoporosis, a condition in which the bones become fragile and easily breakable. This is one reason why it is so important to include adequate calcium in your diet.

Of course, Calcium supplementation is not just for the elderly. It is particularly important that children and young adults receive adequate calcium, so they can build strong bones and have something "in the bank," for later withdrawal.

Bone density peaks around age 30. Achieving a dense bone mass before your middle years is the best protection against later age-related bone loss. For this reason, the RDI has been set at 1,200 mg of calcium for ages 11 through 24. For women, who are most likely to suffer osteoporosis, many healthcare professionals recommend a calcium intake of 1,500 mg daily until the onset of menopause and during pregnancy.

The one percent of our body's calcium which circulates through the blood plays an important role, as well. Recent research indicates a strong correlation between low calcium intake and high blood pressure. Studies suggest that increased calcium intake may provide protection against carcinogens in the colon. Calcium functions in the transmission of nerve impulses and the formation of strong teeth, and it works to regulate the contraction and relaxation of muscles, including our most vital muscle - the heart. In other words, it's indispensable.

Calcium supplementation is advisable for anyone who does not closely monitor dietary calcium intake. Consider how difficult it is to consume adequate sources of this mineral. More than three cups of milk or tofu is needed to supply 1,000 mg of calcium. Although green vegetables, like broccoli, kale and Brussels sprouts, are highly absorbable sources of calcium, you would have to eat over 10 cups of these vegetables to achieve one day's requirement.

Calcium-rich foods are part of a healthy diet, so eat your greens… just don't forget to take a daily supplement. Protect yourself and the ones you love from a dangerous deficiency of this essential mineral.
