Australian Clinical Nutritionist, Warren Maginn said scientists are now verifying the evidence behind the popular wholefood panacea that has endured for centuries.

“Our grandmothers swore by a spoonful of cod liver oil a day. Today resounding evidence shows that cod liver oil may be one of the safest, easiest ways to promote heart health, boost brain efficiency and support a healthy immune system” Mr Maginn said.

“Cod liver oil is making a renaissance as recent studies have shown its rich omega-3 fatty acid profile, along with its naturally occurring levels of Vitamin A and Vitamin D having a multitude of health benefits”.

A clinical trial which collected data from over 21,000 Norwegians has shown that regular use of cod liver oil is negatively associated with high levels of depressive symptoms in the general population.

Another clinical trial on 341 pregnant women found maternal intake of Cod Liver Oil during pregnancy and lactation may be favourable for later mental development of children.

Between 1998 and 2004, researchers followed nearly 40,000 Swedish men and recorded details of their diets. Men who consumed a moderate amount (about 0.3 grams a day) of omega-3 fatty acids in cod liver oil and other fish oils were less likely to develop heart failure than those who consumed little or no omega-3 fatty acids.

Mr Maginn says, “While both fish oil and Cod Liver Oil are both good sources of the two most active omega-3s, EPA and DHA, they each provide slightly different ratios—Cod Liver Oil generally contains about 50% more DHA than EPA, whereas fish oil generally contains about 50% more EPA than DHA”.

“This means that aside from its valuable Vitamin A and D content, Cod Liver Oil is particularly useful for supporting healthy brain and nervous system function, as well as the overall health of all body cells including those of the skin and glands that require more DHA in order to be at their best. Whilst Fish oils, with a higher EPA content, might lend themselves more specifically towards supporting inflammatory conditions such as arthritis and autoimmune diseases”.

“The natural Vitamin A and D content of Cod Liver Oil provides further benefits to eyesight, bone strength and overall immune balance, such as improved wound healing and increased resistance to allergies and infections”.

Three More Proven Nana Cures

  1. An apple a day! – Prescribing an apple a day to all adults aged 50 and over would prevent or delay around 8,500 vascular deaths such as heart attacks and strokes every year in the UK — similar to giving statins to everyone over 50 years who is not already taking them — according to a study.
  2. Chicken soup will cure your cold – it may not cure you but it may help. Scientists now believe that a bowl of the soup may reduce inflammation of the lungs. It is thought that chicken soup slows down the activity of white blood cells that can cause the inflammation.
  3. Honey for coughs – In a trial, honey did even better than the drug, coming out head and shoulders above the popular cough medication (dextromethorphan) at relieving cold and cough symptoms. Researchers believe the stickiness and viscosity of honey helps the cough, while the natural antioxidants can help in the healing process.

Unlike other “cod liver oils” on the market, Nordic Naturals Arctic Cod Liver Oil™ contains no fish body oils or synthetic vitamins or additives.

Nordic Naturals award-winning Arctic Cod Liver Oil™ is an ideal choice to help boost immune system health during the colder months. Vertically integrated from catch to finished product, Arctic Cod Liver Oil far surpasses the strict European Pharmacopoeia Standard for fish oil purity and freshness.
