We understood 59 randomised controlled samples of calcium consumption that advertised BMD since a consequence

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 calcium, 10 used milk or milk powder, two used dairy products, and three used hydroxyapatite loveandseek návštěvníků 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.

Number one analyses

Table 5 ? summarises the outcome of meta-analyses. Increasing calcium intake of dieting sources improved BMD of the 0.6-step one.0% within overall cool and you can overall looks during the 12 months and from the 0.7-step 1.8% during the the web sites together with lumbar lower back and you will femoral neck on 2 years (figs step 1 and you may 2 ? ? . There’s no effect on BMD on forearm.

As soon as we restricted brand new analyses towards 12 randomised regulated samples out-of milk otherwise dairy products, because of the excluding about three products regarding hydroxyapatite, there was nothing change in the results. Calcium supplements improved BMD at all four skeletal websites by the 0.7-1.4% during the 12 months (figs step three and you will cuatro ? ? ), from the 0.8-step one.5% at 24 months (figs 5 and you will six ? ? ), by 0.8-step one.8% on more than two-and-a-half decades (fig seven ? ) (a number of duration of products was three to five age).
