JoAnn E. Manson, MD, DrPH, Principal Investigator, VITAL Main Study and Chief, Division of Preventive Medicine at Brigham and Women’s Hospital describes the goals of the vitamin D and omega-3 Trial (VITAL) trial. VITAL is a randomized, double-blind, placebo-controlled trial in 26,000 participants investigating whether taking daily dietary supplements of vitamin D (about 2000 IU) or fish oil (about 1 gram of omega-3 fatty acids) reduces the risk of developing cancer, heart disease, and stroke in people without a prior history of these illnesses.

Secondary goals of the VITAL trial include study of the role of vitamin D and omega-3s in improving cognitive function, preventing diabetes and reducing the risk of developing insulin resistance or glucose intolerance, and autoimmune diseases such as lupus.
