The Claim
Omega-3 supplementation significantly reduces the DNA methylation-based surrogate biomarkers of plasma proteins linked to mortality risk—specifically PAI-1, leptin, and TIMP-1—by standardized effect sizes of 0.31 to 0.42 units over a three-year period in healthy older adults, indicating a direct molecular effect on inflammation, metabolic dysfunction, and tissue remodeling pathways.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking omega-3 supplements for three years may help lower certain biological markers in the blood that are tied to aging and death risk, like those related to inflammation and tissue repair, by a small but measurable amount.
See the scientific wording
Omega-3 supplementation significantly reduces three of seven DNAm-based surrogate biomarkers of plasma proteins linked to mortality risk—PAI-1, leptin, and TIMP-1—by standardized effect sizes of 0.31 to 0.42 units over three years in healthy older adults, indicating a direct molecular effect on inflammation, metabolic dysfunction, and tissue remodeling pathways.
What the research says
1 studyThis study found that taking omega-3 supplements for three years helped slow down biological aging markers in older adults, which is similar to what the claim says—though it looked at slightly different signs of aging. Still, it supports the idea that omega-3 helps at a molecular level.
