*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
