What the research says

2 studies
  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 1 gram of omega-3 fish oil every day for three years helped slow down the body’s internal aging clock by about 3 to 4 months, according to this big study of older adults.

  2. Study: Dose–response relationship of dietary Omega-3 fatty acids on slowing phenotypic age acceleration: a cross-sectional study

    This study found that people who eat more omega-3 fatty acids (like from fish) tend to have bodies that age more slowly, based on blood tests. Eating about 1 gram a day seems to help, which matches what the claim says.
