Prostate cancer (PCa) is the fifth leading cause of cancer-related death among men worldwide. While traditional risk factors (age, ethnicity, metabolic syndrome) are well established, the role of vitamins in prostate cancer prevention remains controversial. Some studies suggest a protective effect, while others indicate an increased risk depending on the form and amount of intake.
This cross-sectional study, based on NHANES data from 14,977 American men aged 18 years and older, evaluated the association between the intake of 10 vitamins (A, B1, B2, B6, B9, B12, C, D, E, K)—from diet or supplements—and the risk of prostate cancer.
