Taking a daily multivitamin slows biological aging and cognitive decline in older adults.

This advice is based on recent publications from the COSMOS (COcoa Supplement and Multivitamin Outcomes Study), a large-scale randomized controlled trial (RCT). The research did observe a reduction in the epigenetic clock (biological aging) of approximately 2.7 to 5.1 months over two years, as well as a slowing of cognitive decline as reported by the study researchers. However, it is important to note that these results specifically concern elderly populations, who are often prone to micronutrient deficiencies, and cannot be directly extrapolated to young or healthy individuals. The idea of a 'cumulative effect' over 50 years remains a speculative hypothesis, as no study has tracked individuals over such a long period with this precise protocol. Furthermore, the correlation between epigenetic clock biological markers and actual long-term functional health remains a subject of active scientific debate. In short, while the data are encouraging for addressing nutritional gaps, they do not guarantee overall rejuvenation for all ages.
