Nutraceuticals and migraine: further strategy for the treatment of specific conditions.

Nutraceuticals might be defined as food or dietary supplements that provide medicinal or health benefits. Current preventive treatment of migraine includes nutraceuticals as well as conventional drugs. These non-pharmacological therapies, such as magnesium, coenzyme Q10, feverfew, riboflavin, and phycocyanins, are particularly useful in certain categories of patients (adolescents, pregnant or breastfeeding women, the elderly with complex drug therapy, the patient with contraindication to the usual pharmacological therapies) when a conventional drug therapy cannot be prescribed or may be not well tolerated. The evidence currently available confirms a modest efficacy but a very good safety and tolerability profile.
