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.*''Dietary ConsiderationsWheat FreeDairy/ Milk FreeSoy FreeYeast FreeSugar FreePreservative FreeSalt FreeCorn FreeFree of Artificial Colors/Flavors''Serving Size:3 Capsule''Servings Per Container:30''Amount Per Serving Vitamin B2 (riboflavin) 200''mg ''Magnesium (aspartate) 600''mg ''Butterbur (Petasites hybridus) * 150''mg ''''Other ingredients: vegetarian capsule, vegetable stearate ''''''''Suggested use for adults: One capsule, with meals, three times daily, or as directed.
