A major study found no evidence that daily multivitamin use reduces the risk of death, with some data suggesting a slightly higher chance of earlier death among users. Beta-carotene supplements may increase risks of lung cancer and heart disease, while excess iron from multivitamins can lead to overload, raising risks of heart disease, diabetes, and dementia. Most essential nutrients are better absorbed through a balanced diet rather than supplements. The multivitamin industry is a multi-billion-dollar market, often promoting supplements without medical necessity. Experts recommend supplements only for specific nutrient deficiencies, pregnancy, or restricted diets, and always under medical guidance. Prioritizing a nutrient-rich, balanced diet with whole foods is advised over routine multivitamin use, which is not a guaranteed way to improve longevity and may carry health risks.
