<p>This medicine&nbsp;is an absolute bone health formula with more than half a dozen key nutrients. Calcium decreases the rate of bone loss from the femoral neck, the spine and the total body. Since calcium is a nutrient, not a drug, the positive effects of supplemental calcium are most pronounced among women with low to moderate calcium intake. Vitamin D3 helps the body to absorb calcium which helps to reduce age-related bone loss and bone fractures related to osteoporosis. Magnesium helps the body to absorb both calcium and vitamin D3. It also helps to synthesize proteins. Low magnesium status has been associated with postmenopausal osteoporosis. The trace minerals Zinc, Copper and Manganese all play a role in bone development. Zinc is a part of an antioxidant enzyme that helps to prevent cellular destruction, which can cause problems with bone growth and maturation. Copper keeps bones free from thinning. Fifty percent of the total copper content in the body is in the bones and muscles. Manganese, in combination with other trace minerals, helps to prevent bone loss and osteoporosis. Boron works with magnesium and vitamin D3 to enhance calcium absorption and helps to maintain calcium levels in the body. Vitamin C works as an antioxidant. It is also essential for the formation of collagen and aids in iron absorption. Vitamin E serves as an antioxidant, protects biological membranes and stabilizes cellular functions.</p>
