CALCIUM –   Its not all cracked up like we thought it was

There was a meta analysis done which found that there is a 30 percent increased risk of myocardial infarction for those taking 500 mg or more of elemental calcium

2010 meta-analysis showed calcium supplements (without coadministered vitamin D) are associated with increased risk for heart attack (BMJ 2010)

2008 study found calcium supplements are associated with a greater number of heart attacks in postmenopausal women (BMJ 2008)

2004 study showed that people with excess calcium in their coronary artery and who take statins have a 17-fold higher risk of heart attacks than do those with lower arterial calcium levels; researchers concluded that the two most definitive indicators of heart attack were LDL levels and calcium build-up.       Osteoporosis and Bone Density

2010 article presented evidence for a total lack of support in the research for calcium supplements reducing fracture risk (Clin J Am Soc Nephrol 2010)

2007 study showed that calcium from dietary sources has more favorable effects on bone health than calcium from supplements in postmenopausal women (Am J Clin Nutr 2007)

2009 study of postmenopausal women using calcium supplements showed that, although calcium loss from bone was slowed, bone loss was still occurring (Osteoporosis Int. 2009)

2000 study showed that it’s exercise, not calcium, that builds strong bones in teenagers (Pediatrics 2000)
1997 study showed women with the highest consumption of calcium from dairy products had the highest risk of fractures, and those who took calcium supplements had the highest risk for kidney stones (Nurse’s Health Study, Ann Intern Med 1997)

Prostate Cancer 2001 study found men who consumed more than 600mg calcium a day from dairy products showed a 32 percent higher risk of prostate cancer than men consuming less than 150mg per day, and each additional increase of 500mg calcium from dairy was associated with another 16 percent increase in prostate cancer risk (Physicians’ Health Study, Amer J Clin Nutri 2001)

Longevity 2009 study found men consuming the most calcium from food were 25 percent less likely to die over the next decade (Amer J Epidem 2009)
