What are some natural vasodilators or things i can do to prevent vascular headaches?

Nutraceuticals: Nutrients in nutraceutical doses are sometimes vasodilators but many support energy production and downregulate neuroexitotoxity. Magnesium, riboflavin (b2) and coq10 are useful. Also anti-inflammatory herbs feverfew, butterbur. Melatonin and 5htp also sometimes useful. There are herbs and nutrients that can produce vasodilatation in other settings (like raynaud's) but they work less well.

No vasodilator: Vascular headaches result from vasodilation . Medications used to treat migraine headaches constrict blood vessels or block (beta) adrenergic (vasodilating) substances. Alternative medicine approaches include the use of omega 3 fish oil, feverfew, co-enzyme q10 and melatonin. Massage therapy, aromatherapy, acupuncture and acupressure have also been used. Feverfew has scientific support.
