Omega-3 Supplements Shown to Slow Biological Aging in Older Adults

A three-year study found that daily omega-3 intake, especially when combined with vitamin D and exercise, modestly reduced biological aging markers in participants aged 70 and older.

The study, involving 777 participants aged 70 and above, demonstrated that taking 1 gram of omega-3 daily slowed biological aging by approximately 3 to 4 months over three years.
Combining omega-3 with 2,000 IU of vitamin D and 30 minutes of exercise three times a week enhanced the effect, reducing biological aging by nearly four months.
The research utilized epigenetic clocks, which measure biological aging through DNA methylation, to assess the impact of the interventions.
Participants who followed the combined regimen also saw reduced risks of frailty and invasive cancers, with a 39% lower risk of pre-frailty and a 61% reduction in cancer incidence.
While the findings are promising, experts caution that the results are modest and more research is needed to confirm long-term health benefits and applicability to diverse populations.
