Multivitamins Aren’t for Everyone — Benefits May Be Smaller Than Many Think

A U.S. study involving 390,124 generally healthy adults found that taking a daily multivitamin was not associated with a lower risk of death after more than 20 years of follow-up across three large American cohorts. The findings were published in JAMA Network Open.
The result does not mean multivitamins have no useful role. The U.S. National Institutes of Health Office of Dietary Supplements says they can help people meet recommended vitamin and mineral intakes when diet alone falls short, but research has not established them as a general strategy for preventing chronic disease.
For cardiovascular disease and cancer, the U.S. Preventive Services Task Force says the evidence remains insufficient to determine whether multivitamins provide preventive benefits for healthy, nonpregnant adults. It specifically recommends against using vitamin E or beta-carotene for that purpose.
Supplement needs vary by individual. People who are pregnant or planning pregnancy, have a known nutritional deficiency or certain medical conditions may require different guidance, while excessive supplementation can push some nutrient intakes above safe levels.
