Brief Summary
This study will examine whether an intervention with vitamin D or fish oil supplements can reduce the risk of heart failure among adult men and women during a follow up period of up to five years (starting from the time of randomization into the parent VITAL trial). The investigators hypotheses are that both vitamin D and fish oil supplements will each reduce the risk of heart failure.

Outcome Measures
Primary Outcomes (1)
Number of Participants With New Heart Failure Hospitalization
We will consider any hospitalization for heart failure among participants enrolled in the parent VITAL trial for this ancillary study. Incident heart failure are initially captured through annual questionnaires with subsequent validation by a team of physicians with expertise in cardiovascular medicine and epidemiology. We excluded 36 participants with prevalent heart failure at the time of randomization for the primary analysis.
