NEW YORK (Reuters Health) – The most common vitamin and mineral supplementation does not provide a health benefit or permanent damage, a new study suggests.
The study by scientists in Canada found that multivitamins, vitamin D, calcium and vitamin C, the most common supplements, showed no benefit or increased risk of cardiovascular disease, heart attack, stroke or premature death.
In general, vitamin and mineral supplements are taken to add nutrients to the food.
The scientists participating in the study say they were surprised to find very few positive effects of the most common supplements people consume. They did not find any obvious advantages of taking multivitamins, vitamin D, calcium or vitamin C.
The study found that folic acid alone and B vitamins with folic acid can reduce cardiovascular disease and stroke. At the same time, niacin and antioxidants have shown very little effect that may indicate an increased risk of death for any reason.
His team reviewed supplementary data that included vitamins A, B1, B2, B3, B6, B9 (folic acid), C, D and E. beta-carotene. Calcium Iron, zinc, magnesium, selenium.
The term “multivitamin” has been used in this review to describe dietary supplements that contain most of the vitamins and minerals, rather than a selection.
David Jenkins, author of the book said: “In the absence of significant positive data, regardless of the likelihood of low folic acid content in the risk of stroke and heart disease, it is very useful to have a healthy diet to obtain vitamins and minerals. ” The study was published in the Journal of the American College of Cardiology.
“Until now, no dietary supplement has proven to be better than healthy diets for less processed vegetable foods, such as vegetables, fruits and nuts.”
