Comprehensive, high calcium bone support formula OsteoBalance provides 514 mg of calcium per serving from calcium citrate/malate and calcium malate, along with 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. 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 excretion. Like boron, vitamin D3 reduces urinary calcium loss but is also a key nutrient because it enhances calcium absorption.
