Did you know that before advancements in pharmaceutical processing allowed for the creation of ultra refined fish oil, health care providers have always advocated intake of natural fish oil for good health. Fish oil has been proven to be beneficial to the human body because it contains essential omega 3 fatty acids, DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid,) ounces in a liter all of which can help suppress any kind of physiological inflammation. Additionally, experts believe that the omega 3 fatty acids in the fish oil help regulate bad cholesterol in the body - which in turn, is great for keeping the heart healthy, pumping and whole.

Omega 3 fatty acids can also improve the conditions of people who may be suffering from cardiac arrhythmias and rheumatoid arthritis. A steady increase of this supplement is said to reduce the occurrence of anxiety, depression, stroke and even the onset of certain types of cancer as well. As such, fish oil is usually derived from "fatty" fish sources like flounder, herring, lake trout, mackerel, salmon, sardines and tuna. However, recent studies have shown that the best sources of fish oils are those extracted from the bodies of the fish, instead of the livers ?

which was traditionally used. 1. Apparently, fish oils extracted from the liver contain Vitamin A, which can be a good addition to anyone's diet. But since the person is taking in concentrated forms of fish oil, there is also a concentration of Vitamin A. Unfortunately, Vitamin A overdose or hypervitaminosis A leads to abdominal pains, blurry vision, drowsiness, headaches, irritability, jaundice, muscle pains, nausea, vomiting, and overall weakness. In extreme cases, too much Vitamin A in the system can lead to serious medical complications like: diarrhoea, drying of mucous membranes all over the body, fatigue, hair loss, insomnia, unrelenting fever, weight loss and the higher probability of bone fractures.

This condition can also be extremely fatal to developing foetuses, and may cause orange-yellow skin discoloration in very young children. Therefore, to limit the possibility of overdosing with Vitamin A, health care providers prefer to prescribe ultra refined supplements instead. ounces in a liter order ounces in a liter to make the grade, these pharmaceutical grade fish oils are certified as extracted only from the bodies of the fish sources, and not the liver or other internal organs. At the same time, these ultra refined sources are purified to such a degree that "contaminants" (in this case, other minerals) remain absent.

2. Although it is a valuable mineral, mercury is also present in concentrated forms with some fish oil supplements. In fact, there are greater numbers of similar supplements out there that are being marketed despite having high levels of mercury. The bad news is that concentrated ounces in a liter forms of mercury is not only toxic to the human system, it can be fatal as well. Burning sensations on the skin, dead skin peeling off in layers (desquamation,) high blood pressure, itching, kidney dysfunction, pink skin discoloration, profuse sweating, swelling (oedema), and unnatural heart beat are all classic signs of mercury poisoning.
