Cod Liver Oil
There are many forms of fatty acid supplementation to get the needed Omega-3s, Omega-6s, DHEA, etc. Cod liver oil is one form of essential fatty acid supplementation that can help benefit one's overall health. It contains certain "fatty acids" that prevent the blood from clotting easily. These fatty acids also reduce pain and swelling. Cod liver oil is also a source of vitamin A and vitamin D. It is also used as a source of fat called omega-3 for heart health, depression, arthritis, and other conditions, but there is no good scientific evidence to any use.
