Effects of calcium supplementation on body weight: a meta-analysis. For rickets and osteomalacia, the requirements for calcium and vitamin D appear to be interrelated in that the lower the serum vitamin D level (measured as 25-hydroxyvitamin D [25(OH)D]), the more calcium is needed to prevent these diseases [21]. The recommended daily allowances (RDA) for calcium are: Boys 9-18: 1300 mg Men 19-70: 1000 mg Men 71+: 1200 mg Girls 9-18: 1300 mg Women 19-50: 1000 mg Women 51+: 1200 mg Of course, more isn't always better - excessive supplement intake has been tied to potential cardiovascular events. [, Cormick G, Betrn AP, Metz F, Palacios C, Beltrn-Velazquez F, Garca-Casal MLN, et al. A meta-analysis of 23 RCTs in 4,071 participants showed that calcium supplements providing 162 to 2,000 mg/day (combined with vitamin D in 10 RCTs) for 2 weeks to 5 years was associated with low-density lipoprotein cholesterol levels that were 4.6 mg/dL lower and high-density lipoprotein cholesterol levels that were 1.9 mg/dL higher [68]. Calcium. [, Ananth CV, Keyes KM, Wapner RJ. Over time, postmenopausal women can develop osteoporosis, in which bone strength is compromised because of lower BMD and bone quality [1]. On average, women lost 1.28 mm/year of height in the supplementation group and 1.26 mm/year in the placebo group. Subgroup analyses suggested that the inverse association between dietary calcium intakes and metabolic syndrome risk was stronger in women than men. The following groups are among those most likely to need extra calcium. Supplementation with both calcium and vitamin D or consumption of dairy products fortified with both nutrients increased total BMD as well as BMD at the lumbar spine, arms, and femoral neck. High doses of iron may also inhibit zinc absorption. In addition, some calcium supplements are combined with vitamins and other minerals. However, not all research supports this claim.

In this meta-analysis, ovarian cancer risk was 20% lower in participants in the highest category of dietary calcium intakes (more than 8201,500 mg/day, depending on the study) than the lowest intake category (less than 362800 mg/day, depending on the study).

Adult men 51-70 years: 1,000 mg. . Be sure to tell your doctor if you're taking calcium supplements. According to 20092012 NHANES data, rates of calcium inadequacy (intakes below the EAR) are higher among non-Hispanic Blacks and non-Hispanic Asians (4748%) than among Hispanics (30%) and non-Hispanic Whites (24%) in the United States [19]. However, findings were negative in another systematic review and meta-analysis that included 14 RCTs of calcium supplementation and 13 trials comparing calcium and vitamin D supplements with hormone therapy, placebo, or no treatment in participants older than 50 years [38].

An expert panel convened by the National Osteoporosis Foundation and American Society for Preventive Cardiology determined, on the basis of moderate-quality evidence, that calcium intakes with or without vitamin D from foods or supplements neither increase nor decrease the risk of CVD or CVD mortality [73]. Total calcium levels can be measured in serum or plasma; serum levels are typically 8.8 to 10.4 mg/dL (2. Dietary calcium intake and the risk of metabolic syndrome: a systematic review and meta-analysis. A prospective cohort study that followed 41,514 adults aged 40 to 69 years in Australia for 13 years found a 25% lower rate of stroke in adults in the highest calcium intake quartile (mean of 1,076 mg/day) than in the lowest quartile (mean of 641 mg/day) [63]. The labels approved by the FDA for dolutegravir advise patients to take dolutegravir 2 hours before or 6 hours after taking calcium supplements [101,102]. Declining levels of estrogen in women during menopause and for approximately 5 years afterward lead to rates of bone resorption that are higher than rates of bone formation, resulting in a rapid decrease in bone mass [7].
