  Purpose

The VITamin D and OmegA-3 Trial (VITAL; NCT 01169259) is a randomized clinical trial in 20,000 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among participants in VITAL and will examine whether vitamin D or omega-3 fatty acids, compared to placebo, reduce the incidence and/or progression of age-related macular degeneration (AMD).

Detailed Description:

This ancillary study to the VITamin D and OmegA-3 TriaL (VITAL) will examine whether vitamin D3 and omega-3 fatty acids can help prevent the onset or progression of age-related macular degeneration (AMD). The study will also examine whether vitamin D3 and omega-3 fatty acids interact with each other, or with specific genes associated with AMD or vitamin D3 or omega-3 fatty acid metabolic activity, to affect the risk of developing AMD.
