Osteoporosis is not caused by a lack of limestone, oyster shell or bone meal. Heart attack, however, may be caused by supplementation with these exact same "elemental" forms of calcium, according to two meta-analyses published last year in the British Medical Journal.
Back in July of 2011, the British Medical Journal published the results of a high-powered meta-analysis which looked at whether or not calcium supplementation had any effect on cardiovascular disease risk. Indeed, this groundbreaking report, which was based on the results of five clinical trials conducted in the US, Britain and New Zealand, involving over 8,000 people, showed that taking elemental calcium supplements of 500 mg or more increased the relative risk of heart attack by 27%.
