Summary

Story summary

The National Cancer Institute studied more than 390,000 U.S. adults, published in JAMA Network Open, finding no mortality reduction from daily multivitamins over 20 years.
Early analyses showed a 4% higher death risk among multivitamin users, likely reflecting underlying health differences rather than a causal effect.
Some groups may benefit from specific supplements, but a diet rich in fruits, vegetables, and whole grains better supports longevity.
