1. Cycling women both taking or not taking oral contraceptives and menopausal women on replacement estrogen ingested 3 g daily of marine fish oil for 30 days.

2. Triglycerides decreased in the contraceptive users, cholesterol and LDL increased in the non-contraceptive user; while LDL decreased in the menopausal women.

3. After 14 days removal of the fish oil, lipid profiles generally returned to a pattern generally thought to be harmful.

4. Fish oil appears to alter lipids favorably in women receiving exogenous estrogens compared to natural circulating estrogen.
