Bone growth is a gradual process that peaks around age 30. The process of bone loss will take longer if there is a good, strong bone foundation. This is why it is important to build and maintain strong bones while we are young. One of the most important minerals necessary to achieve this goal is calcium.

To Get Enough Calcium in Your Bones
The easiest way to ensure that you have adequate calcium stores is two-fold: dietary calcium and weight-bearing exercise. Weight-bearing exercise – like walking, for example – stimulates the mineralization of bone tissue. Moreover, the added benefit of eating a well-balanced diet will help combat bone demineralization in the future.

For some, however, exercise and diet are not sufficient insurance of long-term bone health. Calcium supplementation may be required.

Calcium, as well as other minerals, is stored in bone tissue. A low level of circulating blood calcium triggers bone to release the stored calcium, so that calcium can be utilized in critical areas:

• the heart
• nerve conduction
• muscle contraction of internal organs

Calcium leaching leaves the bone in a precarious position. As long as the body has enough circulating calcium, the bone can have its precious mineral.

Calcium Supplements
Calcium preparations come in a variety of compounds, strengths, and doses. Because of this, it is often confusing to determine which supplement is better. Additionally, since the body can only absorb calcium in small doses (500 mg), taking higher doses at one time is wasteful.

To determine the actual amount of calcium in a product, look on the label for elemental calcium. Different forms of calcium contain different amounts of elemental calcium. The following are some examples of different forms or compounds:

• Calcium Carbonate
• Calcium Citrate
• Calcium Gluconate
• Calcium Lactate

Calcium Carbonate
Calcium carbonate has the highest level of elemental calcium (40%) and is commonly used as an antacid to treat heartburn, acid indigestion, peptic ulcers, and reflux. For many the high level of elemental calcium makes it a good source of supplementation for the treatment of bone-mass-related issues, like osteoporosis.

To optimize absorption of calcium carbonate, it must be taken with an acidic beverage like orange juice or with a meal (because the meal will stimulate acid production in the stomach). Potential side effects are bloating, gas, and constipation. Some advise against the use of calcium carbonate because of its ability to lower stomach acid, something that is normally reduced (and needed) during aging.

Calcium Citrate
Calcium citrate has the second highest level of elemental calcium (20%) and is the most absorbable supplement. However, it is more expensive than carbonate. Calcium citrate is commonly used post-surgically for gastric bypass patients due to its effortless absorbability. Because of its propensity to bind to heavy metals, it is often used in water softeners. It is found in food as a preservative. As a supplement, it must be taken on an empty stomach to ensure adequate absorption.

Calcium Gluconate
Calcium gluconate contains 9% of elemental calcium. In the hospital setting, it is used intravenously to treat hypocalcemia. It is the antidote for magnesium sulfate overdose and is often administered to women who are in preterm labor. Lastly, due to its unique cardiac protective properties, it is used during episodes of hyperkalemia.

Calcium Lactate
Calcium lactate (baking soda) contains 13% of elemental calcium. Added to fresh fruit, it prolongs shelf life; added to sugar-free products, it prevents tooth decay. In this form, it can be taken with or without food because pH levels have little to no impact on its absorbability.

Forms of Calcium to Avoid
Some forms of calcium have the propensity to contain elevated levels of toxic metals such as lead and arsenic. Their usage for human consumption is highly debated.

• oyster shell
• dolomite
• bone meal

Conclusion
In conclusion, the best way to achieve strong bones is through dietary calcium and exercise. Realistically, these options may not be enough for some individuals. The use of calcium supplementation is appropriate and achievable in a variety of ways. Because individual needs and contraindications vary, it is best to consult a health care professional before embarking on a calcium supplement program.
