Principal results of the VITamin D and OmegA-3 TriaL (VITAL) and updated meta-analyses of relevant vitamin D trials
Open accessAbstract
Whether supplemental vitamin D reduces risk of cancer or cardiovascular disease (CVD) is relatively unexplored in randomized trial settings. The VITamin D and OmegA-3 TriaL (VITAL) was a nationwide, randomized, placebo-controlled, 2 × 2 factorial trial of daily vitamin D 3 (2000 IU) and marine omega-3 fatty acids (1 g) in the primary prevention of cancer and CVD among 25,871 U.S. men aged ≥50 and women aged ≥55, including 5106 African Americans. Median treatment duration was 5.3 years. Vitamin D did not significantly reduce the primary endpoint of total invasive cancer incidence (hazard ratio [HR] = 0.96 [95% confidence interval 0.88-1.06]) but showed a promising signal for reduction in total cancer mortality (HR = 0.83 [0.67-1.02]), especially in analyses that accounted for latency by excluding the first year (HR = 0.79 [0.63-0.99]) or first 2 years (HR = 0.75 [0.59-0.96]) of follow-up. Vitamin D did not significantly reduce the co-primary endpoint of major CVD events (HR = 0.97 [0.85-1.12]), other cardiovascular endpoints, or all-cause mortality (HR = 0.99 [0.87-1.12]). Updated meta-analyses that include VITAL and other recent vitamin D trials indicate a significant reduction in cancer mortality but not in cancer incidence or CVD endpoints. Additional research is needed to determine which individuals may be most likely to derive a net benefit from vitamin D supplementation. (VITAL clinicaltrials.gov identifier: NCT01169259).

The VITAL study, which included more than 25,000 healthy individuals, failed to show significant reductions in major cardiovascular events with EPA + DHA supplementation.
“Similarly, both the ASCEND trial [90], conducted in 15,480 diabetic patients without known cardiovascular disease, and the VITAL study [91], which included > 25,000 healthy individuals, failed to show significant reductions in major cardiovascular events with EPA + DHA supplementation.”
From Targeting triglycerides for cardiovascular risk reduction (2026) · cites this paper as [91]
The VITAL Overview (Design; page unavailable) confirms that 25,871 participants were randomized to receive, among other treatments, an EPA+DHA supplement. The VITAL Results and Conclusion (pages unavailable) report no significant reduction in major cardiovascular events for vitamin D, but the passages found do not report that outcome for EPA+DHA. (LLM, conf=0.86)
Experimental — accuracy not yet measuredThe VITAL trial noted a modest reduction in myocardial infarction, but overall cardiovascular risk was unaffected.
“Although results from the VITAL trial noted a modest reduction in myocardial infarction, the overall cardiovascular risk was unaffected [91].”
From Targeting triglycerides for cardiovascular risk reduction (2026) · cites this paper as [91]
The ‘Vitamin D and Cardiovascular Disease—VITAL results’ section reports no reduction in major cardiovascular events, supporting the overall-risk portion of the claim. It also says vitamin D did not reduce myocardial infarction (HR 0.96, 95% CI 0.78–1.19), so the claim’s suggestion of a myocardial-infarction benefit is not supported by the results reported here.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
