Welcome to the VITAL Study
Welcome to the Web site of the VITamin D and OmegA-3 TriaL (VITAL) at Brigham and Women’s Hospital, an affiliate of Harvard Medical School, in Boston, Massachusetts. VITAL is a research study
in 20,000 men and women across the U.S. investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk for developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. Recruitment for the study began in 2010 and is continuing throughout 2012. Please click on Study Q&A to learn more about participating in this important research endeavor.
During the course of the study, this website will be updated regularly to keep participants informed about the study’s progress, as well as health topics that we
hope will be of interest. We will also answer frequently asked questions from participants on this website.
Thank you for your interest!
