Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Fish, particularly oily fish such as salmon, mackerel, and sardines, are sources of omega-3 polyunsaturated fatty acids (PUFAs), which have been investigated for their potential role in migraine prevention and management. Scientific studies have explored the relationship between dietary intake of omega-3 fatty acids and migraine frequency or severity, with some evidence suggesting modest benefits. For example, a randomized controlled trial published in BMJ (2021) demonstrated that increasing dietary omega-3s while reducing omega-6 fatty acids led to a reduction in the frequency and severity of headaches in people with chronic migraines. The proposed mechanism involves the anti-inflammatory properties of omega-3 fatty acids, which may reduce neurogenic inflammation implicated in migraine pathophysiology. However, the overall evidence is mixed, with several studies showing only small or non-significant effects, and meta-analyses cautioning about heterogeneity among trials. Current clinical guidelines do not universally recommend fish oil or increased fish consumption as a primary treatment for migraines, but it may be considered as an adjunctive or preventive measure for some individuals. Thus, while there is scientific interest and some supportive data, the evidence base is not robust, and fish or fish-derived supplements should not replace established migraine therapies.
