    I take great concern in regards to the conclusions that this and multiple other previous cardiology articles have laid claim to in regards to calcium supplementation. Many providers read these articles and tell patients to stop taking calcium, this then results in osteoporosis and fractures which also has a high mortality rate. There must be significant caution in making the conclusions that this article makes. The amount of calcium the patients were taking was quite varied between 500-2,000 mg a day, patients with bone disease need 1200 mg a day in order to maintain normal bone turnover and rebuilding by the osteoblast. There needs to be data from this study showing the poor outcome patient’s calcium supplement amounts. To insinuate that all calcium supplements are bad is not only a disservice but a detriment to our patients. Patients now have access to articles more than ever and will read this and now won’t take their calcium supplements, this means that anyone treating osteoporosis will now have to explain this and other articles. Patients are more likely to believe bad data than good data. The truth is that calcium is needed for good bone health and there is a safe amount that is not a risk to cardiac health. This article amongst others does not bring in that side of the story.

    Conflict of Interest:
    This article is claiming that calcium is detrimental when it is necessary to treat bone disease. Rheumatology amongst many other specialties treat bone disease. I also speak for Amgen products that treat osteoporosis.
