Increasing research indicates that magnesium deficiency may decrease the severity of PMS complaints, like headaches and migraines. In this 4 month double-blind, placebo-controlled study, magnesium supplementation at a dose of 360 milligrams a day was given for two months to determine in magnesium supplementation reduced menstrual migraine headaches. Indexes for headache pain indicated that magnesium supplementation did reduce symptoms. The Menstrual Distress Questionnaire (MDQ) scores were also reduced in the magnesium group.
According to researchers:
“These data point to magnesium supplementation as a further means for menstrual migraine prevention, and support the possibility that a lower migraine threshold could be related to magnesium deficiency.”
