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.
