CONCLUSIONS Dietary calcium intake is not associated with risk of fracture , and there is no clinical trial evidence that increasing calcium intake from dietary sources prevents fractures .
OBJECTIVE To examine the evidence underpinning recommendations to increase calcium intake through dietary sources or calcium supplements to prevent fractures .
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
