Multivitamins don't increase longevity: 20-year study

A study published in the Journal of the American Medical Association found that daily multivitamin intake does not help increase longevity. The research, spanning 20 years and involving nearly 400,000 adults, showed no reduction in mortality risk. Dr. Neal Barnard highlighted potential harm from excess iron, copper, and beta-carotene in multivitamins. He recommended obtaining nutrients from food and suggested individual supplements for specific deficiencies like B-12 and vitamin D.
