Studies show Cod Liver Oil can Reduce Joint Pain
Latest research now shows that cod liver oil may reduce joint pain.
If your joints are sore and stiff you may seek out supplements as an initial treatment, especially when some prescription medications can cause unwanted side effects.
Many nutritional supplements, vitamins and herbal treatments have been used for decades to ease the aches and pains that can accompany a host of health conditions.
It isn’t a big surprise that many patients now turn to these natural therapies and treatments to treat joint pain and inflammation.
Research shows that this process can work and that some of these non-medicinal treatments can really make a difference.
How Does Cod Liver Oil affect Joint Pain?
Cod liver oils contain the omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Studies have shown that these essential fatty acids may play a significant role in countering inflammatory joint conditions in the body. Cod liver oils are also a natural source of vitamin D. From a nutritional point-of-view, nutritionists and doctors agree that getting adequate levels of this vitamin can help your body produce stronger and healthier bone cells.
The Arthritis Foundation states that omega 3 fatty acids from fish may modify inflammation in rheumatoid arthritis without the gastrointestinal side effects seen with some traditional treatments.
The Foundation went on to further state that “….according to the results of at least 13 studies involving more than 500 participants, supplementation with omega-3 fatty acids significantly reduced RA symptoms. Research also suggests omega-3s may help arthritis patients lower their dose of NSAIDs….”
Review of Cod Liver Oil Joint Pain & Arthritis Studies
A number of these medical studies have shown cod liver oils can have a positive effect on joint pain, cartilage health and the amount of pain medication needed to manage symptoms.
The following is a brief review of some notable studies:
1. United Kingdom – In 2002, scientists released a study showing cod liver oils slowed down the destruction of joint cartilage in osteoarthritis.
In this particular study, researchers analyzed tissue samples of the patients’ cartilage and joint tissue from their knee joints.
Half of these patients had been taking 2 daily capsules of 1000 mg. extra high-strength cod liver oil and the other half received a placebo.
Researchers found 86% of patients taking cod liver oil had zero or significantly reduced levels of a cartilage-destroying enzyme.
Based on these results, researchers believe cod liver oil can reduce the enzymes associated with cartilage break-down and joint pain.
2. Cod liver oils may also help reduce non-steroidal drug usage in treating certain forms of arthritis. A study published in the May 2008 Rheumatology Journal showed omega 3 fatty acids in cod liver oils can be used as a non-steroidal anti-inflammatory drug sparing agent in rheumatoid arthritis.
97 patients were randomized to receive either 10 grams of cod liver oils containing 2.2 grams of essential fatty acids or air-filled placebo capsules.
Researchers discovered that 39% of patients taking cod liver oil reduced their steroid medications by over 30%, whereas only 5% of the patients taking the placebo were able to reduce steroid usage.
3. A study done at The Institute of Phytopharmaceuticals in Berlin, Germany concluded that cod liver oil can be recommended for the treatment of rheumatoid arthritis.
When doctors gave rheumatoid arthritis patients 1 gram capsule of cod liver oil every day for 3 months they experienced a 52% decrease in morning stiffness and swollen joints. These same patients also felt their joint pain reduced by over 60%.
4. A Norwegian study published in the European Journal of Clinical Nutrition showed cod liver oils may also reduce pain. A cross-sectional study using data from a 1985 Norwegian Health Survey showed people with musculo-skeletal pain experienced less pain when they took cod liver oil. Researchers found a 33% stronger association with the perception of less pain, compared to people that didn’t include cod liver oils in their diets.
The medical database, Pubmed.com also contains over a dozen published studies on cod liver oils and arthritis. These studies showed cod liver oil may offer the following benefits:
- Could help reduce the enzymes that destroy joint cartilage.
- May lower the amount of these enzymes that cause joint pain.
- Can decrease ‘morning stiffness’ and swollen joints.
- May help improve bone mineral density.
While this is only a small sampling of research studies, the overall data appears to be encouraging.
An alternative therapy to cod liver oils is using fish oils on arthritis. However, at this point, nutritional therapy for arthritis is still experimental.
A number of these studies used different dosages of fish oils and omega 3 fatty acids. Determining the best cod liver oil dosage for arthritis and joint pain still needs to be researched.
Following a healthy diet and moderate exercise can offer some benefits to maintaining and strengthening your bones and joints.
Please consult your doctor before making any changes to your treatment plan.
