We know for a fact that the benefits that fish oil can give are numerous. It is now being studied if fish oil can even be used to treat a certain kind of arthritis among other things. Fish oil needs to be consumed because the body cannot really produce Omega-3 fatty acids on its own.
Among the finest sources of Omega 3 is fish oil. This is because fish oil provides both EPA and DHA. The chance for toxic contamination is very high right now because of the various toxins in the ocean nowadays. To still get Omega 3 without the poisonous things that you can get from fish oil, supplements are advisable.
