Researchers from Harvard TH Chan School of Public Health, Karolinska Institute (Stockhilm) and Brinham and Women’s Hospital (Boston) investigated how multivitamin use is associated with the risk of CVD in men who were initially (as baseline) healthy. They studied over 18,500 male physicians (≥40 yrs) from the Physicians’ Health Study 1 cohort who were free of CVD and cancer at baseline. All self-reported lifestyle and clinical factors, plus intake of selected foods and dietary supplements. During a mean follow-up of 12.2 years, there were no significant associations observed among baseline multivitamin uses compared with nonusers for the risk of major CVD events. However, at a duration of 20 years or more, a 44% reduction of risk of major CVD events. There was no evidence of any safety concerns from long-term multivitamin use.
