Effect of omega-3 fatty acids supplementation on insulin resistance in women with polycystic ovary syndrome: Meta-analysis of randomized controlled trials.

Background: Several studies have shown that omega-3 polyunsaturated fatty acids (PUFA) may improve insulin resistance in various diseases. However, the possible effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation on insulin resistance in PCOS still remains unclear. We evaluated the effect of omega-3 PUFA supplementation on insulin resistance in women with PCOS in a meta-analysis.
