A recent study indicates that daily multivitamin supplements could slow biological aging by approximately four months. Researchers observed this effect over a two-year period in healthy adults around age 70.
The study, published in Nature Medicine, involved nearly 1,000 participants. Those taking a daily multivitamin-multimineral (MVM) supplement showed a reduced rate of biological aging, as measured by specific methylation markers on DNA, compared to placebo groups. This effect was more pronounced in individuals who started with a higher biological age relative to their chronological age.
However, experts emphasize that multivitamins are not a sole solution for healthy aging. They stress the critical importance of a balanced diet rich in fruits and vegetables, alongside regular exercise. While MVMs can help address potential micronutrient deficiencies, they are seen as a complementary approach rather than a standalone intervention.
Some specialists remain skeptical, pointing to a lack of conclusive clinical benefits for the general public and suggesting that commercial interests may drive supplement consumption without sufficient evidence.
