Patient Education

Cod Liver Oil


What is it? Cod liver oil can be obtained from eating fresh cod liver or by taking supplements. It is a source of vitamins A and D and a fat called omega-3.

Cod liver oil contains certain "fatty acids" that prevent the blood from clotting easily. These fatty acids also reduce pain and swelling.

Cod liver oil is used for heart health, depression, arthritis, and many other conditions, but there is no good scientific evidence to support these uses.
