Tables 2 and 3 show the study design and selected baseline characteristics for trials of calcium supplements, without and with additional vitamin D, respectively. ? ? Further details are in tables A-C in appendix 2. Of the 15 randomised controlled trials of dietary sources of servizi incontri over 50 calcium, 10 used milk or milk powder, two used dairy products, and three used hydroxyapatite preparations. Of the 51 trials of calcium supplements, 36 studied calcium monotherapy, 13 co-administered CaD, and two were multi-arm studies of both. Table 4 summarises other features of the trials ? . Most of them studied calcium without vitamin D in women aged <70 living in the community; the mean baseline dietary calcium intake was <800 mg/day; and most trials lasted ?2 years. A calcium dose of >500 mg/day was used in most trials, but a higher proportion of trials of calcium supplements used a dose of ?1000 mg/day. Table C in appendix 2 shows our assessment of risk of bias. Of the 15 trials of dietary sources of calcium, we assessed two as low risk of bias, six as moderate risk, and seven as high risk. Of the 51 trials of calcium supplements, we assessed 19 as low risk of bias, 12 as moderate risk, and 20 as high risk.

Dining table 5 ? summarises the outcomes of the meta-analyses. Broadening calcium supplements consumption off fat loss supply increased BMD of the 0.6-step 1.0% in the total stylish and you will complete system on 1 year and by the 0.7-step one.8% during the these sites and the lumbar lower back and you will femoral shoulder at the couple of years (figs step 1 and you can dos ? ? . There was zero affect BMD during the forearm.

As soon as we minimal this new analyses for the a dozen randomised regulated examples of milk products otherwise dairy products, by the leaving out three examples off hydroxyapatite, there is certainly absolutely nothing improvement in the results. Calcium enhanced BMD after all five skeletal internet sites by the 0.7-step 1.4% during the one year (figs 3 and you can cuatro ? ? ), by 0.8-step 1.5% in the a couple of years (figs 5 and 6 ? ? ), and by 0.8-1.8% at more than two-and-a-half ages (fig seven ? ) (set of duration of trials was three to five age).
