Omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), have a moderate level of scientific evidence supporting their role in the prevention or slowing of aging-related decline, primarily through cardiovascular, cognitive, and anti-inflammatory effects. Multiple epidemiological studies have associated higher intake of omega-3 fatty acids with reduced risk of cardiovascular disease, a major aging concern. Randomized controlled trials (RCTs) and meta-analyses suggest modest benefits for heart health, including reduced triglycerides and lowered risk of cardiac events, although the effect on overall mortality in the elderly is still debated.

In terms of cognitive aging, some studies indicate that omega-3 supplementation may slow cognitive decline in older adults, particularly those with mild cognitive impairment, but results are mixed, and benefits are less pronounced in those with established dementia. The anti-inflammatory properties of omega-3s are also theorized to contribute to healthier aging by reducing systemic inflammation, a process linked to age-related diseases. However, the evidence here is considered moderate, not definitive.

Overall, omega-3 fatty acids are not a cure-all for aging, but there is a reasonable scientific rationale and moderate clinical evidence for their use in supporting healthy aging, especially in the context of heart and brain health. Their use is supported by dietary guidelines and recommended for most adults, particularly those at risk for cardiovascular disease.
