Vitamin D and Omega-3 Fatty Acids in Primary Prevention of Cancer and Cardiovascular Disease
The purpose of this five-year study is to determine the role of vitamin D, marine omega-3 fatty acids, or the combination of vitamin D and omega-3 fatty acids, as compared to placebo in the primary prevention of cancer and cardiovascular disease. Nationwide, 20,000 people will be recruited for this study, including 5,000 African-Americans. At Rush University Medical Center, we anticipate recruiting approximately 1,500 African Americans.
