A new study from Australia suggests that higher intakes of folic acid seem to decrease the frequency of migraine in women, especially in those with elevated homocysteine levels.
Based on data from an earlier randomized controlled trial (1), the dietary folate intakes and the frequency and severity of migraine attacks with aura were analyzed among 141 adult females with a history of migraine (2). The study results showed that women with higher folate and folic acid intakes had a significantly lower frequency of migraine attacks with aura compared to the women with lower intakes. In participants with elevated blood levels of homocysteine due to a genetic variation of the methylenetetrahydrofolate reductase (MTHFR) gene (relevant for homocysteine metabolism), migraine frequency was strongly related to the intake of the more bioavailable folic acid.
The scientists commented that folic acid, vitamin B6 and B12 supplementation have been previously shown to reduce migraine disability, frequency, and severity in patients with migraine with aura (3). Moreover, the B group vitamins are crucial coenzymes in the maintenance of homocysteine blood levels (4). Elevated homocysteine levels have been shown to be an independent risk factor for cardiovascular disease as well as being associated with endothelial dysfunction. Although alteration in vascular function and cerebral blood flow has been identified in people suffering from, the exact role vascular dysfunction plays in migraine development is yet unknown (5).

The number of people who exercise, and their understanding of the role of nutrition in sports performance, is increasing: The percentage of Americans and Europeans who are physically active increased significantly over the last decade (1-3). In addition, people are tending to stay active for longer (4). The body needs carbohydrates, protein, fats (especially polyunsaturated omega-3 fatty acids), vitamins and minerals in order to function properly. Prolonged exercise performed on a regular basis may result in increased micronutrient losses from the body or in an increased rate of turnover, resulting in the need for an increased dietary intake. Today’s science of sports nutrition is sophisticated, revealing new insights about the measurable benefits of micronutrients, the amounts needed thereof, and the appropriate timing of intake.
