The importance of omega 3 DHA fish oil - Omega 3 DHA fish oil

Natural fish oil comes in triglyceride form. This is the oil that you get when you "squezze" the fish and extract the natural oil from it. The drawback from this particular form of fish oil is that it usually has low overall omega-3 content because it's not concentrated and generally has high levels of contaminants such as heavy metals, PCBs, dioxins etc.
