The Claim

Daily supplementation with 1 gram of omega-3 fatty acids (330 mg EPA + 660 mg DHA) for three years significantly slows biological aging as measured by epigenetic clocks in healthy older adults aged 70 and older, reducing PhenoAge, GrimAge2, and DunedinPACE by standardized effect sizes of 0.16 to 0.32 units (equivalent to 2.9–3.8 months of reduced biological aging).

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.

In plain English

Taking a daily omega-3 supplement for three years might help slow down how fast your body ages at the cellular level, making you biologically younger by a few months compared to people who don’t take it.

See the scientific wording

Daily supplementation with 1 gram of omega-3 fatty acids (330 mg EPA + 660 mg DHA) for three years significantly slows biological aging as measured by epigenetic clocks in healthy older adults aged 70 and older, reducing PhenoAge, GrimAge2, and DunedinPACE by standardized effect sizes of 0.16 to 0.32 units (equivalent to 2.9–3.8 months of reduced biological aging), suggesting omega-3 may be a targeted intervention to modulate molecular aging processes.

What the research says

1 study
  1. Study: Individual and additive effects of vitamin D, omega-3 and exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial

    Taking a daily omega-3 supplement for three years helped slow down the body’s biological aging process in older adults, as measured by special molecular clocks. It’s like the supplement helped their cells stay younger longer.
