A recent study found that older adults who took a daily multivitamin for two years showed about four months slower biological aging compared to those who did not. The research analyzed blood samples from 958 participants with an average age of 70 and used several measures of biological age, which reflects cellular health rather than actual age. Researchers say the results are promising but note it’s too early to know if this leads to longer or healthier lives.
