The health benefits of adding cod liver oil to your diet for the purposes of improved physical well-being have been well-documented, but did you know that cod liver oil could also be beneficial to your mental health and well-being?
Cod liver oil is massively nutritious, containing omega-3 fatty acids, Vitamin A and Vitamin D. It is generally recognised as having the potential to provide a variety of health benefits, the best-known being stronger bones, reduced inflammation and less joint pain, but there are also arguments claiming that cod liver oil also improves brain function, can reduce symptoms of depression and anxiety, improves cognitive function and impacts on mood. The arguments for the miraculous properties of cod liver oil are as follows:
- Inflammation
Cod liver oil contains omega-3 fatty acids which could suppress the production of bodily proteins which create chronic inflammation. Vitamins A and D possess high antioxidant properties, which can reduce inflammation by impacting on harmful free radicals.
- Bone Health
Bone mass begins to decrease at around the age of 30; this can become problematic in later life and the possibility of bone fractures can increase, especially in post-menopausal women. It has been argued that Vitamin D can decrease the likelihood of age-related bone loss because it facilitates the absorption of calcium into the body.
- Joint Pain
A variety of studies into Rheumatoid Arthritis and joint pain have revealed that patients who regularly take cod liver oil supplements reported a reduced level of joint pain and were subsequently able to reduce their intake of prescription anti-inflammatory medication.
- Symptoms of Anxiety and Depression
Research into the impact of cod liver oil on mental state is on-going and inconclusive; however, what the research does suggest is that there is ‘something’ in cod liver oil which can alleviate symptoms to some extent. It seems more plausible that this is due to the Vitamin D content which, it has been argued, can stimulate the production of hormones such as seratonin, and it is generally accepted that higher levels of Vitamin D in the blood can reduce minor symptoms of depression.

It has also been argued that there is a link between chronic inflammation and anxiety or depression, and although some studies claim that cod liver oil could reduce symptoms of low mood, more research is needed before a reasonable conclusion can be reached; although inflammation can decrease and some improvement in mood has been acknowledged, the level of improvement is very small.
- Other health benefits
Eye Health: The omega-3 fatty acids and Vitamin A present in cod liver oil have been shown to offer some level of protection against, for example, glaucoma and age-related macular degeneration, by reducing inflammation in the body.
Heart Disease: incorporating omega-3 fatty acids into the diet can reduce the risk factors of heart disease, although it is important to note that it cannot prevent heart disease developing. The presence of omega-3 fatty acids can lower blood pressure, increase HDL cholesterol (the ‘goodie’), prevent plaques forming in the arteries, and reduce the production of triglycerides.
Stomach and Gut Ulcers: results of animal studies are suggesting that cod liver oil could enable the healing of stomach ulcers by reducing inflammation in the gut, and it has also been argued that cod liver oil can suppress genes which create inflammation of the gut. Users of prescription anti-inflammatory medication can be at risk of developing stomach ulcers, as can smokers and individuals who experience acid reflux.
Ok, so how much should I take?
One teaspoon of cod liver oil contains 90% of the RDI for vitamin A, and 113% of the RDA for Vitamin D. Taking 1000mg capsule has long been the advisable daily dose for individuals with arthritic conditions, however, research from 2005 has concluded that higher doses appear to be extremely beneficial to individuals awaiting joint replacement surgery. In this study, the higher dose resulted in two specific changes in the body: firstly, a huge reduction in the production of an enzyme which can cause damage to the cartilage, and secondly, a reduction in certain enzymes which cause joint pain.
