Cod Liver Oil

Cod Liver Oil

“Cod liver oil provides a rich source of omega-3 fatty acids, namely EPA and DHA,” explains nutritionist Robert Hobson. “However, unlike other fish oils, cod liver oil also contains vitamins A and D.

“These days, cod liver oil is taken for its omega 3 content,” Robert continues. “Omega-3 fatty acids cannot be produced in the body so we need to obtain them from our diet.”

  • Benefits for the joints

    While cod liver oil may be taken as a supplement by those who don’t eat oily fish, it also has a number of other benefits that could help with overall health.

    The anti-inflammatory properties in cod liver oil mean it could be beneficial for joint health and the symptoms of arthritis. “In the over 50's, cod liver oil may be taken to help relieve joint pain,” says Robert. “Evidence suggests fish oil (including cod liver oil) helps to maintain joint mobility and flexibility and diminish morning stiffness.”

  • Benefits for the brain

    In 2008, UCLA's Brain Research Institute and Brain Injury Research Centre analysed more than 160 studies which looked at the effects different foods had on brain function. The results showed omega 3 had a beneficial effect on the learning and memory functions of the brain. It was also thought to help with depression and mood disorders.

  • Benefits for the heart

    The omega 3 content in cod liver oil could also be beneficial for your heart as it is thought to lower cholesterol levels, a major contributor to heart disease. “Fish oil could reduce the risk of heart disease and stroke, especially in those who have already had a heart attack or are at increased cardiovascular risk,” Robert says.

  • Benefits for the bones

    For strong healthy bones, our body needs vitamin D, the main source of which is sunlight. However, as we age our body’s ability to absorb vitamin D declines, leaving us susceptible to conditions such as Osteomalacia (softening of the bones) and Osteoporosis (increase risk of fracture). Cod liver oil is a rich source of vitamin D and, when taken with vitamins A and C, could promote a healthy immune system.

  • Benefits for the eyes

    Not only could vitamin A be beneficial for the immune system, it could also be good for eye health. The Royal National Institute of Blind People (RNIB) reports many studies have revealed vitamin A, found in fruit and vegetables such as tomatoes, raw carrots, green beans and oranges, as well as in cod liver oil, could help maintain healthy cells and tissues in the eye.
