Higher Increases in Plasma n‐3 Polyunsaturated Fatty Acids Following Fish Oil Supplementation in Postmenopausal Females Compared With Age‐Matched Males

Lipids, EarlyView.
ABSTRACT The effects of fish oil supplementation on omega‐3 (n‐3) polyunsaturated fatty acids, particularly intermediates between eicosapentaenoic acid (EPA, 20:5n‐3) and docosahexaenoic acid (DHA, 22:6n‐3), that may provide valuable metabolic information, have not been fully characterized in older populations.
