Facts About Calcium: A to Z

Facts about calcium A to Z covers the common and sublime findings about one of the most heavily researched minerals in the world.  Calcium plays a role in most biological functions in the human bodyFacts-About-Calcium-A-to-Z | Review Article. Besides comprising much of bone, calcium has been linked to muscle activity --including the heart beat -- nervous system function and normal blood clotting. The body always maintains a small level of calcium in blood to perform these functions. The remaining calcium in the body is stored in the bones and teeth.

Scientific Calcium  Facts
Calcium is a common alkaline metal found in the earth and sea water. It is also naturally available in foods such as dairy, certain leafy green vegetables, seafood (sardines, clams, oysters) and tofu. There are numerous different forms of calcium salts; the most common is calcium carbonate, which is calcium and carbon. Calcium is typically mined or gathered from oyster shells.

Benefit Facts about Calcium
Bones, Muscles and Cramps
The most widely recognized function of calcium is to support our skeleton. Bone undergoes continuous remodeling, with constant removal (resorption) and deposition of calcium into new bone.  The balance between bone resorption and deposition changes as we age. Bone formation exceeds resorption in growing children, whereas in early and middle adulthood both processes are relatively equal. In aging adults, particularly among postmenopausal women, bone breakdown exceeds formation, resulting in bone loss. Throughout life, calcium is continually added to bones, with peak bone mass being achieved generally around 35 years of age. Dietary calcium intake from childhood through young adulthood is extremely important to preventing bone fractures.

With muscle activity, the brain sends an impulse to the muscle which stimulates the release of calcium. The calcium then bonds to the proteins within the muscle tissue, allowing them to contract, or move. Calcium deficiency may cause muscle spasm or cramps.

Blood Pressure
Studies suggest that high calcium diets contribute to controlled blood pressure. According to a study published in the Journal of Pediatrics, The American Heart Association’s   “DASH Diet contains a number of other important minerals, the positive results indicate that calcium does play some role in blood pressure control.

Weight Control
Published studies suggest a link between calcium and weight loss or weight control.. Some researchers suggested that dairy overall was the key link to weight control, but the consensus appears to be that adequate calcium from any source can assist with body weight. Of course, it must be noted, that calcium is only one component in managing weight.  Many factors, especially diet and lifestyle, contribute to body weight changes. Some researchers believe that calcium may help moderate appetite, although the area of weight loss is controversial and requires more research.

Differences Among Calcium Forms
Of course calcium can only be beneficial if it is well absorbed.  Some calcium forms, such as AdvaCAL Facts-About-Calcium-A-to-Z | Review Articlehave been especially beneficial in increasing bone density, suggesting a high rate of bioavailability.  Proper, consistent calcium intake and bioavailability are the keys to getting the needed bone benefits. That is perhaps one of the most important facts about calcium
