Omega-3 fatty acids (EPA and DHA) are known to lower elevated triglycerides. Some small trials in people with PCOS have reported changes in inflammation markers, hormones or insulin measures, but results are mixed and benefits for PCOS symptoms or fertility are not established.
People with PCOS who are discussing cholesterol and triglyceride management with a clinician. Whether it suits you depends on your health, medicines and test results — ask a clinician.
Trials have used roughly 1–4 g of combined EPA + DHA daily. This is not a recommendation; ask your clinician. Doses vary by product and person; this is not personal medical advice.
Triglyceride changes have been seen in weeks to months in studies.
Fishy aftertaste, burping, nausea or loose stools. Avoid fish-oil products if you have a fish allergy unless your doctor agrees.
Choose reputable brands that test for contaminants. Avoid cod liver oil in pregnancy (high vitamin A).
Evidence level (our editorial summary, not a formal grading): Limited to moderate.
Pregnancy & breastfeeding: Omega-3s are commonly advised in pregnancy; talk to your provider about type and dose.
Medication interactions: High doses may add to the effect of blood thinners.
Talk to a healthcare professional before use if you are pregnant, breastfeeding, planning pregnancy, have a medical condition, take any medicine, or are scheduled for surgery.
