Daily Multivitamin-Mineral May Lower Risk of Heart Disease in Women
A recent study suggests that taking a daily multivitamin and mineral supplement may lower the risk of heart disease by more than 35% in women. No similar effect was seen in men or for multivitamin supplements.
Participants in the study included 8,678 people age 40 and older who took part in the third National Health and Nutrition Examination Survey, which had an average 18 years of follow-up. After analyzing the data, the researchers found that there was no general association between taking multivitamin and mineral supplements and cardiovascular disease risk.
However, when they narrowed the data down to look specifically at length of supplementation the researchers found that women had a 35% lower risk of developing cardiovascular disease if they took the supplements for more than three years.
On the other hand, the researchers observed a slightly lower risk for men who took the supplements for between one and three years but cautioned that the sample size was not large enough to draw a conclusion.
Researchers from the Office of Dietary Supplements at the US National Institutes of Health conducted the study. It was published online ahead of print on January 7, 2015, in The Journal of Nutrition.
Multivitamin-mineral supplements contain minerals such as calcium, magnesium, zinc, phosphorous, manganese and copper. They may also contain iron, selenium, iodine, chromium or molybdenum.
Previous studies have shown that multivitamin-mineral supplements may aid in weight loss, reduce the risk of cardiovascular disease, and boost general physical health. Other studies have also shown that the cells of people who routinely take multivitamins have a younger biological age.
