Does Fish Oil Interact With Birth Control?

Taking fish oil supplements may prove beneficial for many people. It effectively lowers high triglyceride levels and seems to help people maintain good heart health. It also may treat a variety of conditions, including high blood pressure, attention-deficit disorder, dyspraxia, IgA nephropathy, bipolar disorder, Raynaud’s syndrome, rheumatoid arthritis, asthma, psoriasis and developmental coordination disorders. However, women who take birth control pills may not see the full effect of at least one of these benefits.

Fish Oil and Birth Control Medications

Although more research needs to be done, birth control pills may interfere with fish oil’s effectiveness in lowering triglyceride levels. For women who are interested in taking fish oil supplements for other purposes, this may not be a cause for concern. No other known drug interactions exist between fish oil supplements and birth control medications. However, this does not necessarily mean that no other interactions exist. Always ask your doctor before taking a fish oil supplement while on birth control medications.
