Omega-3 has been found to be helpful in a number of areas particular to women. From reducing the pain of dysmenorrhoea(1) (in combination with other fatty acids) to increasing uterine blood flow and facilitating pregnancy(2). Supplementation with omega-3 during pregnancy lowers the risk of premature birth and can increase the length of pregnancy and birth weight by promoting foetal growth by improving placental blood flow. Intake of omega-3 fatty acids during pregnancy and breast feeding may facilitate the child’s brain development. There is also some evidence that supplementation with omega-3 might help to prevent pre-eclampsia, postpartum depression, menopausal problems, postmenopausal osteoporosis, and breast cancer.

A study into hot flushes in menopausal women found a significant reduction in the group taking omega-3 compared to those taking the placebo (6). Research looking at omega-3 and omega-6 content of adipose tissue in patients with breast cancer found lower levels of omega-3 in cases than controls. The ratio of omega-6 to omega-3 was also found to be significantly higher in breast cancer cases. (7) This was confirmed by the Sinapore Chinese Women trial; a prospective trial of 35,000 women in Sinapore. In this study, those with the lowest intake of omega 3 had an increased risk of breast cancer.(8) Furthermore, because elevated triglyceride levels are associated with cardiovascular disease, especially in women; and because omega-3 FA have powerful effects on triglycerides, women in particular gain from an increased intake of these fatty acids. This is especially important in women receiving hormone therapy, which can increase triglyceride levels (9)
