OsteoBalance

†High  calcium osteoporosis support with broad spectrum cofactors
  Now with 1,000 i.u. vitamin D3 per serving (previously 400 i.u.)

OsteoBalance provides 1,200 mg of calcium per serving from calcium  citrate/malate and calcium microcrystalline hydoxyapatite (MCHA).  This formula also includes a comprehensive profile of important  bone building nutrients. Calcium citrate/malate has excellent  bioavailability and provided bone mass support for postmenopausal  women with low dietary calcium intake in a two-year, double-blind  placebo-controlled trial. In a separate two-year trial, calcium  MCHA maintained healthy bone mineral content in volunteers. One  study indicated that concomitant supplementation of the trace  minerals zinc, copper, and manganese with calcium citrate/malate  helped to promote healthy bone metabolism in postmenopausal subjects.  Magnesium supports healthy bone mineral density and boron plays  an important role in reducing urinary calcium and magnesium excret
