Cal-Mag uses only minerals that are guaranteed to be of superior quality for maximum absorption. Independent research suggests that chelated minerals may be more bioavailable than regular ionic minerals. We use pure calcium extracted from Calcium Hydroxide and Calcium Carbonate for Calcium AAC. Calcium is one of the most abundant substances found in the body. Over 99% of all the calcium found in the body is located in the bones and teeth. The primary function of calcium is in the development and maintenance of strong bones and healthy teeth and gums. A constant supply of this mineral is required throughout life, especially during periods of growth, such as childhood, pregnancy and lactation. It is also important in the maintenance of a healthy heart. Calcium may help prevent cardiovascular disease, lower cholesterol levels, is essential in blood clotting and may lower blood pressure. Calcium may prevent bone loss associated with osteoporosis. Osteoporosis is a debilitating disease in which bones become fragile and more vulnerable to breaking and fracturing. If not prevented or if left untreated, osteoporosis can progress until a bone breaks, making the condition painfully evident. These broken bones, also known as fractures, occur typically in the hip, spine, and wrist and often require extensive recovery.Osteoporosis is a major public health threat for more than 28 million Americans, 80 percent of whom are women. In the U.S. today, 10 million individuals already have the disease and 18 million more have low bone mass, placing them at increased risk for osteoporosis. One in two women and one in eight men over age 50 will have an osteoporosis-related fracture in their lifetime. Post-menopausal women are often more susceptible to osteoporosis as a result of possible hormonal imbalance. An insufficient amount of nutrients, poor diet and lack of weight-bearing exercise can also contribute to the onset of osteoporosis.Magnesium is one of the most abundant minerals in sof
