"Question Does vitamin D3 supplementation reduce the risk of developing advanced (metastatic or fatal) cancer among adults without a diagnosis of cancer at baseline?
Findings In this secondary analysis of a randomized clinical trial with 25 871 patients, supplementation with vitamin D3 reduced the incidence of advanced (metastatic or fatal) cancer in the overall cohort, with strongest risk reduction in individuals with normal weight and no reduction among individuals with overweight or obesity.
Meaning These findings suggest that vitamin D3 may reduce the risk of developing advanced cancer among adults without a diagnosis of cancer at baseline; this protective effect is apparent for those who have normal but not elevated body mass index."
