In patients suffering from multiple sclerosis, the immune system damages the protective sheath surrounding the nerves, which sometimes is so debilitating it makes walking difficult because this damage inhibits the ability of the brain and the body to talk to each other. Omega-3 fatty acids are important nutrients that everyone needs, but people with multiple sclerosis may benefit more than others.
Benefits
Many studies have been done to test the effectiveness of omega-3 fatty acids with differing results, according to NutritionMD, a website operated by the Physicians Committee for Responsible Medicine. The general amount given to multiple sclerosis patients in these trials ranged from 6 to 10 g of omega-3 fatty acid supplements. The Agency for Healthcare Research and Quality reviewed the data and found that even though some trials showed a decrease in multiple sclerosis progression or incidence, more evidence is needed for a conclusion that these amounts of omega-3s are beneficial for multiple sclerosis sufferers.
Sources
Omega-3 supplements come in pill or liquid form. Fish oil is known as the richest source of omega-3s, but people who do not eat fish or have allergies can also get omega-3 supplements from flax seeds or flax oil. Some types of fish are also sources of omega-3, such as herring, sardines, salmon, and mackerel. Other food sources include walnuts and canola oil. Consuming up to 3 g of omega-3 fatty acids is typically safe.
Warnings
Some prescription drugs interact with omega-3s, possibly decreasing the effectiveness of the drugs, according to the National Multiple Sclerosis Society. There is a possibility that omega-3s render the multiple sclerosis drugs Rebif, Betaseron, Avonex, and Copaxone less potent, though this is not conclusive. Anticoagulant drugs, including aspirin and similar medications, may also interact unfavorably with omega-3s. Consult a physician if you are on any medication.
Considerations
Although supplements may benefit multiple sclerosis patients, they cannot take the place of a proper diet. A well-balanced diet that is low in fat and high in fiber helps people with multiple sclerosis remain in good health. Avoid special diets that are said to treat multiple sclerosis as there is little evidence that any are effective. Also, some special diets may recommend toxic levels of some vitamins while including too few or none at all of other important nutrients. Ask your physician for diet recommendations.
