It is believed that calcium and vitamin D may play a part in heart disease prevention. However, there are few studies done to actually verify this claim.
Researchers Wang, Manson, Song and Sesso analyzed existing studies done on calcium and vitamin D to see if there is any indication of cardiovascular protection from these two common supplements taken by millions of people. Despite this detailed analysis, the conclusion is made somewhat unclear because most of the existing studies were small and not originally designed to look at cardiovascular risks.
The bottom line? Calcium supplements do not reduce the risk of disease of the heart. Vitamin D at moderately high dose of 1,000 IU daily might help cut the risk down.
