She found that people who took fish-oil supplements for four months did not have longer telomeres than people who took a placebo. However, across all the groups, the greater the increases in omega-3s in the blood relative to their levels of omega-6 fatty acids, the greater the telomere lengthening over that period.8 The omega supplementation also reduced inflammation, and the greater decreases in inflammation were associated with increases in telomere length.
