In a beneficial multicenter, double-blind, placebo-managed demo, 672 fit men (indicate age 61

Up until the relationships ranging from calcium and you can prostate cancer are explained, it is practical for males to consume a maximum of step 1,000 to just one,200 milligrams/day’s calcium (dieting and supplements combined), that is needed by Food and Nutrition Panel of your own Institute of Treatments (pick RDA) (9)

8 decades) was basically randomized so you’re able to everyday calcium supplements supplements (1,two hundred mg) to possess several years. While no rise in the danger to possess prostate cancer tumors might have been said during the a ten.3-year pursue-up, calcium supplementation lead to a life threatening risk loss of the period comprising out-of 24 months shortly after medication started to two years after medication ended (150). Into the a review of the brand new literary works composed during 2009, the usa Institution getting Health care Research and you can High quality revealed that maybe not all of the epidemiological knowledge discover a link anywhere between calcium supplements intake and you may prostate disease (151). The fresh new remark stated that six away from 11 observational training failed to track down statistically extreme confident relationships between prostate cancer tumors and you can calcium intake. But really, from inside the five studies, everyday consumption out-of 921 to dos,000 mg out of calcium was discovered to be of a keen improved danger of development prostate malignant tumors in comparison with consumption varying out of 455 to 1,100000 milligrams/day (151). Inconsistencies certainly knowledge strongly recommend state-of-the-art interactions between the chance facts having prostate cancer tumors, and additionally mirror the issues away from examining the result out-of calcium supplements consumption into the totally free-life style some one. Such as for example, that people with high milk products and you may/otherwise calcium consumption was seen to be more likely to end up being engaged in compliment life-style or even more browsing find medical assistance is also mitigate the fresh mathematical importance of an association with prostate cancers exposure (152).

Create calcium supplements boost the chance to own cardiovascular illnesses?

Multiple observational studies and you can randomized managed trials have raised inquiries out of the potential negative effects out-of calcium into cardiovascular exposure. The study of information regarding Kuopio Weakening of bones Exposure Grounds and you may Avoidance (OSTPRE) potential analysis found that users from calcium amongst ten,555 Finnish people (ages 52-62 decades) got a beneficial 14% higher risk of creating coronary artery problem than the non-complement profiles throughout a mean realize-up out of 6.75 age (153). The prospective study of 23,980 users (35-64 years of age) of your own Heidelberg cohort of your own Eu Potential Studies towards Disease and you may Nutrients cohort (EPIC-Heidelberg) noticed that extra calcium consumption are definitely in the chance out of myocardial infarction (coronary attack) but not with the risk of stroke or heart disease (CVD)-related mortality just after a hateful realize-up out-of eleven age (154). But really, the application of calcium supplements (?eight hundred mg/go out against. 0 mg/day) is with the an elevated chance of CVD-relevant mortality when you look at the 219,059 boys, however from inside the 169,170 ladies, as part of the Federal Institute of Wellness (NIH)-AARP Dieting and Wellness investigation and you may adopted to possess a hateful period off a dozen ages. CVD mortality into the men was also seen to be somewhat higher with total (fat reduction including supplemental) calcium supplements consumption of 1,500 mg/date and you may significantly more than (155).

In addition, the secondary analyses of two randomized placebo-controlled trials initially designed to assess the effect of calcium on bone health outcomes also suggested an increased risk of CVD in participants daily supplemented with 1,000 mg of calcium for five to seven years (156, 157). In the Auckland Calcium Study of 1,471 healthy postmenopausal women (ages ?55 years), calcium supplementation resulted in increased risks of myocardial infarction and of a composite cardiovascular endpoint, including myocardial infarction, stroke, or sudden death (156). The analysis of data from 36,282 healthy postmenopausal women randomized to receive a combination of calcium (1,000 mg/day) and vitamin D (400 IU/day) or a placebo in the Women’s Health Initiative/Calcium-Vitamin D supplementation study (WHI/CaD study) initially reported no adverse effect on any cardiovascular endpoints with calcium (and vitamin D) compared to placebo (158). A re-analysis was performed with data from 16,718 women who did not take personal calcium supplements (outside protocol) during the five-year study (157). Although criticized on the approach taken (134, 159), the investigators estimated that women supplemented with calcium and vitamin D had a 16% increased risk of clinical myocardial infarction or stroke and a 21% increased risk of myocardial infarction compared to those who received a placebo (157). However, in another randomized, double-blind, placebo-controlled trial – the Calcium Intake Fracture Outcome (CAIFOS) study – in elderly women (median age, 75.1 years), the supplementation of 1,200 mg/day of calcium for five years was not found to increase the risk of vascular disease or related mortality (160). The WHI/CaD data re-analysis also failed to show an increased risk of mortality due to myocardial infarction or coronary artery disease with calcium therapy (156). Also, after an additional follow-up of 4.5 years at the end of the treatment period in the CAIFOS trial, the investigators reported fewer cases of heart failure-related deaths with supplemental calcium compared to placebo (160). In another randomized, placebo-controlled trial of calcium and/or vitamin D3 (RECORD trial), the evaluation of the effect of 1,000 mg/day of calcium (alone or with 800 IU/day of vitamin D) reported no significant increase in the rate of mortality due to vascular disease in 5,292 participants ages 70 years and older (161). A recent cross-sectional analysis of the Third National Health and Nutrition Examination Survey (NHANES III) evaluated the association between calcium intakes and cardiovascular mortality in 18,714 adults with no history of heart disease. No evidence of an association was observed between dietary calcium intake, supplemental calcium intake, or total calcium intake and cardiovascular mortality in either men or women (162).
