Douglas Laboratories Cal/Mag 1001
Cal/Mag 1001 tablets provide 500 mg of elemental calcium and 500 mg of elemental magnesium to provide a 1:1 dose ratio of calcium to magnesium. Other nutrients including boron, glutamic acid, Vitamin C and D3 are also included to assist the body in maintaining a healthy bone structure.
Each serving contains:
Vitamin C - 150 mg
Vitamin D3 - 75 IU
Calcium - 500 mg
(from Calcium Citrate/Carbonate/Ascorbate Complex)
Magnesium - 500 mg
(from Magnesium Aspartate/Ascorbate/Oxide Complex)
Boron (from Boron Citrate Complex) - 3 mg
Glutamic Acid - 150 mg
Other ingredients: Cellulose and vegetable stearate.
As a dietary supplement, adults take 3 tablets daily or as directed by your healthcare professional.
The adult human body contains approximately 1,200 g of calcium, about 99% of which is present in the skeleton, and 20-30 g of magnesium with about 60% located in bone. Bone is constantly turning over, a continuous process of formation and resorption. In children and adolescents, the rate of formation of bone mineral predominates over the rate of resorption. In later life, resorption predominates over formation. Therefore, in normal aging, there is a gradual loss of bone. Intestinal calcium absorption ranges from 15 to 75% of ingested calcium.
Vitamin D is a key regulatory hormone for calcium and bone metabolism. Adequate vitamin D status is essential for ensuring normal calcium absorption and maintenance of healthy calcium plasma levels. Magnesium absorption is independent of vitamin D status and ranges from 30 to 60% of ingested magnesium. Caucasian and Asian women typically have low peak bone densities, and therefore, are at the greatest risk of developing osteoporosis. It is generally accepted that obtaining enough dietary calcium throughout life can significantly decrease the risk of developing osteoporosis. Among other factors, such as regular exercise, gender and race, calcium supplementation during childhood and adolescence appears to be a prerequisite for maintaining adequate bone density later in life. But even elderly patients can benefit significantly from supplementation with dietary calcium and magnesium. Cal/Mag 1001 provides a beneficial source of dietary calcium together with other nutrients that assist in the maintenance of healthy bone structure and function. For example, boron affects the composition, structure, and strength of bone. It appears to be necessary for calcium and magnesium absorption, their adequate renal reabsorption, and their incorporation into the bone matrix.
