Hypocalcemia can be asymptomatic, especially when it is mild or chronic [23]. Average daily calcium intakes from both foods and supplements are 1,156 mg for men, 1,009 mg for women, and 968 to 1,020 mg for children [18]. But evidence about such health benefits is not definitive. Furthermore, women who met the RDA for calcium for adults (1,000 to 1,200 mg/day, depending on age) had an 18% lower risk of metabolic syndrome, but the association was not statistically significant in men who met the RDA for calcium. Some scientists have questioned these findings because of the lack of statistical power (the studies were designed to detect differences in bone health measures, not cancer incidence), details from the investigators on the study sample and randomization procedures [45,46].

Other forms of calcium in supplements include gluconate and lactate. Another effect of chronic calcium deficiency is osteomalacia, or defective bone mineralization and bone softening, which can occur in adults and children [1]. Age-related bone loss can also occur in men and lead to osteoporosis, but fracture risk tends to increase in older men about 5 to 10 years later than in older women [1]. In a systematic review and meta-analysis of 9 cohort studies in 750,275 men, the risk of prostate cancer was 2% higher for each 400 mg/day increment in total dietary and supplemental calcium intake, but nondairy and supplemental calcium intakes were not associated with prostate cancer risk [58]. Several observational studies have shown that the risk of prostate cancer might be higher with higher calcium intakes, but possibly only when the calcium comes from dairy foods.

Calcium citrate is less dependent on stomach acid for absorption than calcium carbonate, so it can be taken without food [1]. [, Yao X, Hu J, Kong X, Zhu Z.

Evidence on dose-response relationships between calcium intakes and risk of stroke or stroke mortality was inconsistent. Calcium supplementation during pregnancy might reduce the risk of preeclampsia, but the benefits might apply only to women with inadequate calcium intakes, and much of this evidence comes from studies with methodological weaknesses [76,77]. The evidence is mixed and more research is needed before doctors know the effect calcium supplements may have on heart attack risk. Bone remodeling is required to change bone size during growth, repair damage, maintain serum calcium levels, and provide a source of other minerals [4]. Calcium deficiency can reduce bone strength and lead to osteoporosis, which is characterized by fragile bones and an increased risk of falling [1]. Average daily intakes of calcium from foods and beverages are 1,083 mg for men aged 20 and older and 842 mg for women [ 18 ].

For example, a longitudinal cohort study of 1,490 women aged 42 to 52 years at baseline who were followed for 1012 years found that fracture risk was not significantly different in calcium supplement users (some of whom also took vitamin D supplements) and nonusers, even though supplement use was associated with less BMD loss throughout the study period [36]. It is a leading cause of maternal and neonatal morbidity and mortality that affects about 4% of pregnancies in the United States [75]. Br J Nutr 2013;110:1384-93. Dual x-ray absorptiometry testing of bone mineral density can be used to assess cumulative calcium status over the lifetime because the skeleton stores almost all calcium in the body [3].
