*Highly absorbable form of calcium; combined with magnesium, vitamin D, boron, silica and xylitol Now with 400 i.u. vitamin D3 per serving (previously 200 i.u.)
Randomized, double blind, placebo-controlled studies have reported statistically significant benefits of calcium supplementation for bone health. Magnesium, like calcium, is an essential bone matrix mineral that promotes healthy bone metabolism. A trial involving 2,038 older individuals indicated that higher intakes of magnesium were positively associated with bone mineralization for certain individuals.
Vitamin D promotes intestinal calcium and phosphorous absorption and reduces urinary calcium loss, essential mechanisms for maintaining healthy calcium levels in the body and for healthy bone composition. A recent 7-year study involving 36,282 women indicated that combined supplementation of calcium and vitamin D promoted healthy hip bones. Boron supports calcium, phosphorous, magnesium and vitamin D metabolism and plays a role in reducing urinary calcium and magnesium excretion. In addition, it strengthens the connective structure in bone matrix. Silica is a component of co
