MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Interest in a possible role for vitamin D deficiency as a risk factor for cardiovascular disease was stimulated by studies showing a seasonal variation in cardiovascular disease, which is much higher in winter, when body levels of vitamin D are low, than in summer.
Main findings are that bolus monthly doses of vitamin D supplementation do not prevent against cardiovascular disease, even in people with low levels of vitamin D.
MedicalResearch.com: What should readers take away from your report?
Response: That monthly doses of vitamin D do not prevent against cardiovascular disease.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Response: We don’t know whether or not daily doses prevent against cardiovascular disease. We will have to await the results of other large clinical trials currently underway which are giving daily doses. However, these will not report their findings for 2-3 years.
