Overview InformationCod liver oil can be obtained from eating fresh cod liver or by taking supplements.
Cod liver oil is used for high cholesterol, high triglycerides, kidney disease in people with diabetes, high blood pressure, heart disease, osteoarthritis, depression, an autoimmune disease called systemic lupus erythematosus (SLE), glaucoma, and middle ear infections (otitis media).
Some people put cod liver oil on their skin to speed wound healing.
When taken in appropriate doses by mouth, cod liver oil seems to help lower high triglycerides (a type of blood fat), lower high blood pressure, and treat some symptoms of kidney disease related to diabetes. It doesn’t seem to lower high cholesterol or reduce arthritis pain. Other uses are still under investigation.
How does it work?Cod liver oil contains certain "fatty acids" that prevent the blood from clotting easily. These fatty acids also reduce pain and swelling.
Uses & Effectiveness
Likely Effective for
- Lowering blood fats called triglycerides. Taking cod liver oil by mouth can reduce triglyceride levels by 20% to 50% in people with high triglyceride levels.
Possibly Effective for
- High blood pressure. Taking cod liver oil by mouth seems to lower blood pressure (both numbers) a small, but important, amount in people with mild high blood pressure.
- Kidney disease in people with type 2 diabetes. Taking cod liver oil seems to reduce protein in the urine, a marker for kidney disease severity.
Possibly Ineffective for
- Cholesterol disease that runs in families (familial hypercholesterolemia).
Insufficient Evidence for
- Depression. There is some evidence that people who take cod liver oil have fewer symptoms of depression than other people.
- Irregular heartbeat in people with heart disease. There is some early evidence that cod liver oil might help to prevent certain types of irregular heartbeat.
- Ear infections in young children. Preliminary research suggests that taking cod liver oil along with a children's multivitamin-mineral product containing selenium might prevent or decrease the number of ear infections in young children.
- Heart disease.
- Systemic lupus erythematosus (SLE).
- Wound healing.
- Other conditions.
Side Effects & SafetyCod liver oil is LIKELY SAFE for most adults and children when taken by mouth. It can cause side effects including belching, bad breath, heartburn, loose stools, and nausea. Taking cod liver oil with meals can often decrease these side effects.
High doses of cod liver oil are POSSIBLY UNSAFE. They might keep blood from clotting and can increase the chance of bleeding. Vitamin A and vitamin D levels might also become too high with high doses of cod liver oil.
The safety of cod liver oil when used on the skin is unknown.
Special Precautions & Warnings:Pregnancy and breast-feeding: Cod liver oil is POSSIBLY SAFE when used in amounts that provide no more than the recommended daily intakes of vitamin A and vitamin D. Cod liver oil is POSSIBLY UNSAFE when taken in larger amounts. Women who are pregnant or breast-feeding should not take cod liver oil that provides more than about 3000 mcg of vitamin A and 100 mcg of vitamin D.
Diabetes: There has been some concern that cod liver oil or other fish oils might increase blood sugar in people with diabetes. But there is no strong research that supports this concern. High blood pressure: Cod liver oil can lower blood pressure and might cause blood pressure to go too low if used along with medications for high blood pressure. Be careful when using cod liver oil if you are taking high blood pressure drugs.
Be cautious with this combination
Medications for high blood pressure (Antihypertensive drugs) interacts with COD LIVER OIL
Cod liver oil seems to decrease blood pressure. Taking cod liver oil along with medications for high blood pressure might cause your blood pressure to go too low.<br/><br/> Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.
Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs) interacts with COD LIVER OIL
Cod liver oil might slow blood clotting. Taking cod liver oil along with medications that also slow clotting might increase the chances of bruising and bleeding.<br/><br/> Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
The following doses have been studied in scientific research:
- For lowering triglycerides: 20 mL of cod liver oil per day.
- For high cholesterol: 30 mL of cod liver oil per day.
- For lowering blood pressure: 20 mL of cod liver oil per day.
