Women who used multi-vitamin and -mineral supplements for longer than three years reduced their risk of dying of cardiovascular disease (CVD) in a new study of U.S. adults (J. Nutr. 2015. Published online Jan. 7, 2015).
The study used data from more than 8, 600 subjects 40 years or older (from the NHANES III, 1988 to 1994) as well as mortality data reported by the National Death Index through 2011. While the researchers from the National Institutes of Health’s (NIH) Office of Dietary Supplements (ODS) observed no significant association between CVD mortality and multivitamin use in the overall data, they found a significant association with those who used the supplements for longer than three years compared with nonusers. This finding was largely driven by the significant association among women.
This research follows a number of studies showing multivitamins’ positive effects on heart health. In 2010, the use of multivitamins was inversely associated with heart attacks in women, especially those without a history of CVD who used the supplements for five years or longer (Am J Clin Nutr. 2010 Nov;92(5):1251-6). That study included 31,000 women with no history of CVD and 2,200 women with a history of CVD aged 49 to 83 years from Sweden.
Additionally, a 2003 study from Stockholm reported Low-dose multivitamins may prevent heart attacks in subjects aged 45 to 70, and another study from the same year found multivitamins with antioxidant properties had beneficial effects on homocysteine and low-density lipoprotein (LDL) oxidation measures.
The mounting evidence of multivitamin’s effect on heart health is interesting, especially with the recent legal battle Bayer is in on this front. The Center for Science in the Public Interest (CSPI) is seeking to prevent Bayer from making claims for its One A Day multivitamins. Specifically, CSPI accused Bayer of misleading consumers about its multivitamin’s effects on heart health, immunity and energy. CSPI alleged Bayer makes heart health claims based on products that contain vitamins B6, B12, C, E and folic acid, but the organization said studies have shown supplemented vitamins don’t prevent heart disease.
