ESSENTIAL for health: Omega 3 ; 6 are essential fatty acids, meaning they are necessary for good health. It is interesting that you ask snake oil, as that is also a good source of omega 3's ; thus very beneficial to those who were deficient. Some get enough omega 3's from flax, hemp or other oils but some can't convert those to the epa/dha found in fish oil. For summary of research on benefits see http://bit.Ly/1cpbzsb.
