Cod liver oil is a widely used nutritional supplement which is derived from liver of Atlantic cod fish. It is an essential oil which abounds in omega-3 fatty acids – eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is also a source of significant sources of vitamin A and vitamin D. Health benefits of the cod liver oil have been known since 18th century. It is then that a physician from Manchester England named Darbey gave the oil to the patients suffering with rheumatism. In 1820th the oil started being prescribed to children to prevent rickets and help with vitamin D deficiency. One of the best varieties is blue ice cod liver oil.
Various studies have found that cod liver oil may be beneficial for a variety of conditions:
BLUE ICE COD LIVER OIL ALLEVIATES SYMPTOMS OF ARTHRITIS
A study conducted in Germany evaluated how patients who suffered with arthritis respond to taking 1 gram of cod liver oil daily over the period of three months. The findings showed that the level of pain was reduced with the consistent oil intake. Another study at Cardiff University in Wales found that cod liver oil alleviated pain and cartilage damage caused by osteoarthritis among a number of patients. The researchers also saw a decline in the need for joint replacement.
COD LIVER OIL REDUCES THE RISK OF CORONARY ATHEROSCLEROSIS
A research conducted by Dr. Schacky and other researchers from Munchen University in Germany revealed that taking of one and a half grams of n-3 fatty acids slowed down progression of established coronary artery disease.
MAY HELP WOUNDS HEAL FASTER
The scientists at the Aarhus University Hospital conducted an experiment using the hairless mouse ear wound model. After applying cod liver oil based ointment to wounds they detected faster wound healing. In the opinion of the Danish scientists: “Vitamin A seems to have an important role in accelerating wound healing and could be the active component in cod liver oil”.
VITAMIN D IN THE OIL MAY HELP COGNITIVE PERFORMANCE
The study conducted by the researchers at Manchester University in England found that the levels of vitamin D are linked to brain performance among middle-aged and older people. The findings suggested that the people who had low levels of vitamin D had poorer brain function. This vitamin is abundantly found in cod liver oil. For example, according to Weston A. Price Foundation 1 mL of blue ice cod liver oil contains approximately 390 IU (international units). By taking a teaspoon this oil an estimated 1950 IU of vitamin D can be taken.
There are many other benefits which are linked to fatty acids and vitamins contained in cod liver oil which are still being researched. According to WebMD.com taking the blue ice cod liver oil orally may help some people lower triglycerides, the blood fats which if elevated may lead to heart diseases. According to the same site the oil may help people suffering with high blood pressure to lower it. In addition, the cod liver oil (such as blue ice cod liver oil) can be beneficial for kidney health of the people with type 2 diabetes.
You can find a large variety of cod liver oil supplement brands on the market. However not all of them are made equal. According to theWeston A. Price foundation, some brands undergo manufacturing processes which eliminate all of the vitamins. Such products lack sufficient levels of vitamin A and contain virtually no Vitamin D. Certain manufacturers have even added synthetically derived vitamin A and D to the purified cod liver oil. Fortunately, currently there are several manufacturers which produce fermented high-vitamin cod liver oil naturally without using any heating (which decreases nutritional value).
The following is the list of recommended high-vitamin fermented cod liver oil based on the Weston A. Price foundation review. The list of the best cod liver oil brands is topped by blue ice cod liver oil variety. You can find the list of the best brands and product descriptions below:
