Long-Term Study Finds Daily Multivitamins Do Not Boost Longevity
A 20+ year analysis of 390,000+ generally healthy U.S. adults found that daily multivitamin use does not lower overall mortality or deaths from cancer, heart disease, or stroke. An initial slight (about 4%) higher death risk among users likely reflects underlying lifestyle differences rather than a harmful effect. While certain groups may benefit from specific supplements (folic acid in pregnancy, post-bariatric surgery, and some eye-disease nutrient combinations), for most adults a daily multivitamin is unlikely to extend lifespan. Emphasis remains on diets rich in vegetables, fruits, legumes, and whole grains, which are consistently linked to longer life.
