Magnesium is a multi-purpose mineral and is responsible for initiating more than 300 metabolic reactions in the body. It is remarkable to note that appropriate doses of magnesium supplements works towards the reduction of the frequency of migraine attacks. The mineral is believed to show positive response on all the brain chemicals involved in aggravating migraines. It has been noticed that adequate stock of magnesium in the body affects the serotonin receptors as well as NMDA receptors held responsible for these painful episodes. Further, several studies have shown that both cluster headaches and migraines among the patients respond well to the shots of intravenous magnesium.  

In most of the cases, doctors recommend the concentration of 400mg-500mg of magnesium per day for the gradual alleviation of this problem. However, any sort of a migraine preventive medicine should be taken with utter precaution by heart, liver and kidney patients. Further, the dosage of this supplement should be taken in a right combination of calcium. Women takers must opt for those medicines in which the calcium content is double the content of magnesium. At last, it is advisable to look for magnesium supplements in combination with other salts like magnesium sulfate, magnesium oxide and magnesium citrate.
