Researchers from Brazil studied the preventive effects of omega-3 fatty acids on migraine. To this end, they examined 60 chronic migraine patients who were divided into two groups. One group of patients received an omega-3-fatty acids supplement; the other group was administered a placebo in addition to conventional treatment. Two-thirds of the patients taking omega-3 fatty acids showed an 80% reduction in the number of headache days per month. In the placebo group, improvement was significantly lower. This indicates that omega-3 fatty acids are helpful in the prevention of migraine attacks. Further details can be found in the study.
