Summary
The VITamin D and OmegaA-3 TriaL (VITAL; NCT01169259) is a randomized clinical trial in
20,000 U.S. men and women studying 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 VITAL participants and will study
whether vitamin D or fish oil: (A) in the overall VITAL cohort, reduces the number of persons
diagnosed with anemia and (B) in a subcohort of 900 participants seen in Boston, effects
long-term changes of the proteins in blood in both anemic and non-anemic individuals who
provide blood samples at the start of the study and again 2 years later.
