Calcium Carbonate, 500 mg, 100 Tablets
Calcium is the most plentiful mineral in the body and is vital to the formation and health of teeth and bones. Once formed, bones and to a lesser degree, teeth, continue to rebuild and remodel by gaining and losing minerals, especially calcium. In fact, 98% of the body’s calcium is stored in bones and teeth, providing them with structure and rigidity.
Bones and teeth also serve as a readily available source of calcium for the blood, where it is needed for muscle contractions, blood clotting, transmitting nerve impulses, secreting hormones, and activating enzymatic reactions. Certain hormones maintain normal blood calcium levels by signaling a withdrawal from available bone stores.
In disease prevention, adequate calcium intake can lower elevated blood pressure, maintain healthy cholesterol levels, control blood sugar, and contribute to a healthy colon. Calcium may even support weight loss by burning more fat as fuel.
Since bones give up calcium throughout our lifetimes for a variety of biological needs, a deficit in later years may be present, leading to osteoporosis, a condition in which a rapid or gradual loss of bone occurs, causing breaks and fractures to the hips and joints. The disease can also lead to collapsed vertebrae in the spine causing intense pain and a stooped posture. It is estimated that more than 25 million people in the US, primarily women, suffer from osteoporosis.
The best way to prevent bone loss is to start early in life. Up to about age 20, people can still contribute dietary calcium to their bone stores for use later in life. During midlife, especially following menopause in women, bone loss begins to accelerate, and the onset of osteoporosis can begin. During this critical time when bone loss is at its peak, both men and women should increase calcium intake in the diet by eating (reduced fat) milk products, small fish with bones, tofu, and dark green vegetables.
Unfortunately, many people do not or can not consume enough calcium-rich food to provide the 1000 to 1200 mg RDA needed for adults over the age of 18. To make matters worse, even if the diet supplies adequate calcium, it is often inefficiently absorbed or excreted faster than it can be assimilated.
To offset this problem, supplements are highly recommended for most adults, especially postmenopausal women. Calcium carbonate is a popular and low-cost source of daily calcium. Aspen Naturally’s calcium carbonate is fortified with 400 IU of vitamin D for optimal absorption.
In order for dietary calcium to be properly absorbed, at least 400 IU of vitamin D must be taken per day.
