Q: I would like to know if Seven Seas - Cod Liver Oil, available in medical shops, is a good source of DHA?

A:Seven seas is the most common brand for Cod Liver oil in the market and it is true that it is a rich source of DHA. Most fish oils supply about 10%-15% DHA, thus upgrading the supply to the body of omega 3 fatty acids. Although cod liver oil is not the only source of DHA, it can be considered an important source, definitely.
