Calcium supplements  increased BMD by 0.7 - 1.8 % at all five skeletal sites at one , two , and over two and a half years , but the size of the increase in BMD at later time points was similar to the increase at one year .
Increasing calcium intake from dietary sources or by taking calcium supplements produces small non-progressive increases in BMD , which are unlikely to lead to a clinical ly significant reduction in risk of fracture
OBJECTIVE To determine whether increasing calcium intake from dietary sources affects  bone mineral density ( BMD ) and , if so , whether the effects are similar to those of calcium supplements .
Calcium supplementation and bone loss in middle-aged women.
This 4-y study investigated the effects of a calcium carbonate supplement on  bone loss in 169 women aged 35 - 65 y , r and omly assigned to placebo and treatment ( 1500 mg Ca/d ) groups in a double-blind design . Bone mineral content ( BMC ) and width ( W ) were measured bilaterally on the radius , ulna , and humerus . BMC and BMC /W loss rates were consistently lower in treatment than in control subjects . Loss was significantly reduced in the left and right humerus and the right radius . In premenopausal subjects , only left humerus BMC loss was significantly reduced by Ca supplementation . In postmenopausal treatment subjects , BMC and BMC /W bone loss was reduced in all 12 ( bilateral radius , ulna , and humerus ) of the bone variables measured , 5 at p less than 0.01 and 2 at p less than 0.05 . Ca supplementation counteracted a large portion of the additional bone loss attributable to menopause in this population
