Fish oil for the treatment of migraine headaches: an introduction
Fish oil, as the name implies, comes from fish. It contains omega-3 fatty acids, which is also found in nuts, seeds and vegetable oils.
Fish oils have been touted for their positive impact on heart health because research on omega-3 fatty acids shows it reduces the risk of abnormal heart risks, slows the rate of hardening of the ateries. Fish, as opposed to supplements, carry a risk of being contaminated with mercury.
A 2002 survey from the Centers for Disease Control and Prevention’s National Health Interview Survey found that 12% of the 30,000 people polled have tried fish oil or omega fatty acids.

Fish oil for migraines – how does it work
According to the American Heart Association the ingredients of fish oil help reduce inflammation, reduces blood clotting, lowers blood pressure and steadies the heart rhythm. These actions, particularly the reduction of inflammation or swelling, may be helpful in reducing the head pain and other migraine symptoms of migraine attacks because it may reduce migraine head inflammation.
Studies on Fish oil and Migraines
Some research suggests that since Fish Oil prevents constriction of blood vessel, it can prevent the actions in the brain that lead to migraine attacks.
A 2002 study of 27 adolescents who took fish oil found that they had fewer migraines, shorter headaches and less severe migraine headaches.
