MigraMAXX contains three ingredients for support of cerebral blood bessels and nerves. Butterbur (Petasites hybridus), standardized for petasins content and processed to remove undesirable pyrrolizidine alkaloids, has emerged as a powerful support on vascular tone and nerve function. Magnesium participates in the regulation of vascular tone and reactivity by influencing platelet function, acting as a mild calcium channel blocker, and helping regulate the effects of serotonin and other neurotransmitters. Riboflavin may help correct certain mitochondrial dysfunctions related to instability of cerebral vasculature.
