Doctors from the nonprofit organization Northwestern Medicine questioned the health benefits of the widespread use of multivitamins. In particular, they believe that taking vitamins by healthy people is a waste of money and will not protect them from the development of cardiovascular, oncological and other diseases. The findings are published in the Journal of the American Medical Association (JAMA).
In the course of the work, experts analyzed data from 84 studies, and came to the conclusion that there is not enough evidence that taking multivitamins can help prevent disease in healthy adults. Also, scientists do not recommend supplementing with beta-carotene due to an increased risk of lung cancer, and do not recommend supplementing with vitamin E, since it does not offer any benefit in reducing mortality.
However, doctors emphasize that eating fruits and vegetables is associated with a reduced chance of developing cardiovascular disease and cancer, so many believe that extracting key vitamins and minerals from them will have the same effect. However, health benefits can only be observed with a balanced diet, as these substances work synergistically, and individual micronutrients may act differently in the body.
However, supplementation may be beneficial for people with specific vitamin deficiencies, such as calcium or vitamin D, but should be taken as directed by a physician. Also, an additional intake of trace elements is necessary for pregnant women or those who are just planning to become a mother.
