Before the relationships ranging from calcium and you may prostate malignant tumors are clarified, it is realistic for men to consume a maximum of step one,100000 to a single,2 hundred milligrams/day’s calcium (dieting and medications shared), which is needed of the Food and Nutrition Board of the Institute of Medicine (pick RDA) (9)

8 many years) were randomized in order to each and every day calcium supplements supplements (step 1,2 hundred milligrams) having few years. If you find yourself no increase in the chance for prostate malignant tumors might have been stated while in the an excellent 10.step 3-12 months realize-upwards, calcium supplements supplementation triggered a significant risk reduction in that point comprising from a couple of years immediately after cures reach 2 years once treatment finished (150). From inside the a look at brand new literary works typed in 2009, the usa Agencies for Medical care Look and you can Top quality showed that not every epidemiological training discover a connection between calcium supplements intake and you will prostate malignant tumors (151). The newest feedback stated that 6 off eleven observational knowledge were unsuccessful to locate mathematically significant positive relationships between prostate disease and you can calcium supplements intake. Yet ,, from inside the four studies, each day intakes out of 921 so you’re able to 2,000 milligrams regarding calcium was seen to be associated with an enthusiastic improved threat of developing prostate malignant tumors in comparison with intakes varying regarding 455 to just one,100000 milligrams/big date (151). Inconsistencies certainly degree strongly recommend complex relationships involving the chance affairs to possess prostate cancers, together with reflect the difficulties from determining the end result of calcium supplements consumption in totally free-traditions anybody. Instance, that individuals with highest dairy and you can/otherwise calcium supplements intakes was seen to be likely to be involved with compliment lifestyles or higher attending look for medical attention can mitigate new analytical significance of an association that have prostate cancers risk (152).

Would calcium increase the exposure getting cardiovascular disease?

Numerous observational education and you may randomized regulated products have increased issues out of the possibility adverse effects from calcium supplements on cardio exposure. The analysis of data on Kuopio Weakening of bones Exposure Grounds and you can Avoidance (OSTPRE) potential data unearthed that users away from calcium between ten,555 Finnish women (years 52-62 many years) had a beneficial 14% higher risk of creating coronary artery problem than the low-complement pages while in the an indicate follow-right up of 6.75 age (153). The mark examination of 23,980 players (35-64 yrs . old) of your own Heidelberg cohort of European Potential Studies toward Cancers and you may Nourishment cohort (EPIC-Heidelberg) seen you to definitely extra calcium supplements intake are surely for the exposure out of myocardial infarction (coronary arrest) however for the danger of stroke otherwise heart problems (CVD)-relevant death just after a hateful go after-right up out of 11 decades (154). But really, employing calcium (?eight hundred milligrams/time versus. 0 mg/day) try associated with the an increased chance of CVD-associated death during the 219,059 people, but not within the 169,170 ladies, as part of the National Institute of Health (NIH)-AARP Diet and Health data and you will implemented for a suggest several months off a dozen age. CVD death into the men was also found to be somewhat higher with complete (weight loss including extra) calcium intakes of just one,500 milligrams/time and over (155).

In addition, the secondary analyses Orlando hookup 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).
