- A recent study discovered that daily multivitamin intake may slow biological aging.
- The researchers state that while multivitamins may not extend life expectancy, they can enhance long-term health.
- While not a cure-all, multivitamins can support a healthier lifestyle when combined with good habits.
People choose to take multivitamins for a multitude of reasons. These supplements can offer various health benefits,
A recent publication in
This study received funding from Haleon (formerly Pfizer Consumer Healthcare) and Mars Inc., both of which provided multivitamins and cocoa extracts. Notably, two authors of the study were financed by these entities, who did not influence the research design.
According to the study’s findings, participants who took a daily multivitamin exhibited a reduction in biological aging by up to 4 months.
“While aging is inevitable, there may be practical methods to postpone the aging process and enhance our quality of life,” remarked study author Sidong Li, MD, PhD, a postdoctoral researcher in the Division of Preventive Medicine at Brigham and Women’s Hospital, Boston, MA, in an interview with Healthline.
“Our research indicates that daily multivitamin-multimineral supplementation may be a cost-effective and accessible approach that promotes healthier aging, especially for those who are already biologically older,” Li added.
The study analyzed 958 individuals aged 60 and above over two years. Participants were randomly distributed into four groups, each consuming different combinations of pills:
- cocoa extract and a multivitamin
- a multivitamin and a placebo
- cocoa extract and a placebo
- two placebos
The research team found that those taking a daily multivitamin experienced a slight reduction in biological aging, equating to approximately 4 months. In essence, these participants aged about 20 months at the cellular level over the 24-month study period.
Researchers utilized five different “epigenetic clocks” to estimate participants’ biological age.
Comparing the findings with the placebo group, individuals consuming multivitamins displayed slower aging as indicated by two of the five clocks.
Interestingly, participants who initially exhibited signs of accelerated biological aging appeared to benefit more significantly from the multivitamins.
“It’s essential to contextualize the significance of these findings,” explained Michelle Routhenstein, a preventive cardiology dietitian at Entirely Nourished, who was not involved in the study.
“These changes reflect biomarker adjustments, not direct evidence suggesting fewer heart attacks, cancers, or an extended lifespan. Therefore, I view the results as promising, yet still in early stages,” Routhenstein informed Healthline.
The study also indicated that cocoa extract did not influence any biological aging measures.
The researchers emphasize that while multivitamins may not necessarily extend life, they could positively impact one’s future health trajectory. Still, individuals who are not currently taking multivitamins should consult healthcare professionals before starting any supplementation.
“It’s encouraging to observe that multivitamins can influence the biological aging process in older adults. However, maintaining a healthy lifestyle is crucial for achieving better quality aging,” stated Li.
Ultimately, the choice to take supplements, including multivitamins, should involve a discussion between individuals and their healthcare providers.
Choosing the right multivitamin involves many factors.
One critical aspect to consider is that multivitamins and supplements are not strictly regulated by the Food and Drug Administration (FDA). Consequently, some products may contain nutrient levels that differ from the amounts stated on their labels.

Furthermore, some multivitamins and supplements may contain ingredients that
“Supplements should supplement, not replace, a nutritious diet. Multivitamins tend to be most beneficial for individuals with dietary gaps, restricted eating habits, or heightened nutrient requirements,” advised Routhenstein.
She also urged individuals to “Choose a formulation that aligns with your age and health status while focusing on correct dosing.”
However, the guidelines indicate that while some older adults may require fewer calories, they still need equal or greater amounts of crucial nutrients.
This suggests a need to emphasize protein intake. Many older adults also lack Vitamin B12, calcium, and vitamin D.
These individuals might want to have a conversation with their healthcare provider regarding multivitamins or other supplements, as dietary requirements can vary significantly between men and women.
“The most significant factors contributing to healthy aging are well recognized,” stated Routhenstein.
She concluded by noting that these lifestyle components have a far more profound impact on long-term health than any single supplement.
