Pushky To everyone who suffers from migraine please know that a study was done using magnesium oxide 500 mg supplement daily. Results were significant showing prevention and reduction in intensity of migraines and headaches. Upon further research I found out that low levels of magnesium in our brain causes headaches and migraines. Especially vulnerable are people on blood pressure diuretic meds. Diuretics flush out magnesium and many other minerals from our body creating imbalance. Do not stop BP meds! They are important to take. Instead supplement with minerals. I personally use a combination of different types of magnesium daily 500 mg. Hope this info helps some one🙏🏻
