Cod liver oil is rich in omega-3 fatty acids, which help promote heart health. Cod liver oil is also rich in vitamins A and D, which your body uses for healthy skin and bones. However, cod liver oil is not safe for everyone, and too much of it can cause serious complications.
Allergies
While cod liver oil allergies are not very common, they are more likely in people who already have a seafood or fish allergy, according Medline Plus. An allergic reaction could manifest itself as itching and hives, trouble breathing and swelling in your face, hands, mouth, and throat. If you have symptoms of an allergy, cease use and contact a physician immediately.
Possible Side Effects
While you may not be allergic to cod liver oil, you may occasionally experience such side effects as bad breath, rashes, intestinal problems and nausea. The gastrointestinal problems related to cod liver oil supplements can be minimized if the doses are taken with meals.
Vitamin Deficiency/Toxicity
According to the Mayo Clinic, fish oils can cause in a deficiency in vitamin E, so most contain added vitamin E to combat this effect. In addition, cod liver oil is high in vitamin A and D. As a result, vitamin toxicity can occur from the use of cod liver oil, especially when used with other vitamin supplements.
Drug Interactions
Cod liver oil may interact with heart medications, including hormone medicines, aspirin, and blood thinners like warfarin. This is particularly dangerous for people taking medicine to lower blood pressure, since cod liver oil has the same effect. If you combine blood pressure medication and cod liver oil, your blood pressure may drop to unsafe levels. If you are on prescription medication, you should ask your doctor if supplements like cod liver oil are safe for you.
Bleeding
The omega-3 fatty acids in cod liver oil may increase your risk of bleeding and hemorrhagic stroke when taken at a high dose. Cod liver oil seems to inhibit your body's ability to form blood clots. This effect is particularly dangerous for people suffering from hemophilia, a genetic defect in which your blood has trouble clotting.
