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 .
The effect of fluoride and calcium on spinal bone mineral content: A controlled, prospective (3 years) study
Summary Daily treatment with 30 mg of sodium fluoride ( NaF ) and 1 g of calcium over a 3-year period increased the bone mineral content ( BMC ) in the spines of women ( n=25 ) with osteoporosis . Determination of the BMC was followed with dual photon absorptiometry ( 137Cs-241Am ) in the third lumbar vertebra . No increase in BMC was found with only 10 mg sodium fluoride in combination with calcium ( n=25 ) , with calcium alone ( n=25 ) , or with placebo ( n=25 ) . No serious side effects were registered . There was , however , minor gastrointestinal distress in one-fifth of the patients taking 30 mg NaF daily
