Effects of Vitamin D and Omega-3 on Cerebrovascular Disease

Summary

The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a completed randomized clinical trial in 25,875 U.S. men and women which investigated whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduced the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. Observational follow-up of participants is currently ongoing. The current study is being conducted among participants in VITAL who experience a stroke event during follow-up and will examine whether vitamin D or omega-3 fatty acid supplementation impact post-stroke outcomes.
