Only one in five adults with migraine consumed their recommended magnesium levels (RDA) through the diet in this study; this number improved to one in four when including dietary supplement intake. Those who achieved their RDA through diet and supplements had 17% lower odds of reporting migraine than those who did not. Furthermore, adults in the highest Q of magnesium consumption through diet had 24% lower odds of reporting migraine than those in the lowest consumption Q. These findings suggest that inadequate magnesium consumption through the diet is associated with migraine in adults and support further investigation of this association. Prospective observations of the relationship between magnesium intake and migraine are needed.
