Research has found that women ages 65 to 80 with omega-3 blood levels in the highest quartile were 20 percent less likely to die from any cause than those in the lowest quartile.

A study published in the Journal of Clinical Lipidology found that higher levels of EPA and DHA omega-3 polyunsaturated fatty acids (PUFA) in red blood cells were associated with a lower risk of all-cause mortality in postmenopausal women. The study specifically examined associations with the omega-3 index, a measure of EPA and DHA levels in red blood cells. Over a 15-year period, the research found that women ages 65 to 80 with omega-3 blood levels in the highest quartile were 20 percent less likely to die from any cause than those in the lowest quartile.

The study analyzed data from more than 6,500 women aged 65-80 who participated in the Women’s Health Initiative Memory Study, which began in 1996.
