The following is an excerpt from the introduction of the article: In the United States, 53% of the population use dietary supplements. Of the people using supplements, 43% use calcium and 37% use vitamin D. However, 63% of women older than 60 years of age reported using dietary supplements (Park et al., 2009). Calcium supplementation, without co-administered vitamin D, increases the risk of myocardial infarction and cardiovascularrelated diseases among postmenopausal women. On the contrary, calcium supplementation with accompanied vitamin D may not produce similar effects.
