Nope! It's always a good idea to talk to your doctor before starting a new dietary supplement, but you don't need a prescription to take Magnesium.

According to multiple scientific studies, the American Headache Society, and the American Academy of Neurology, the answer is yes. Not every clinical trial has shown magnesium to be effective at preventing migraine headaches, but there's enough evidence that it helps that it's a good option to consider.

Experts think magnesium may help prevent the wave of brain signaling, called a cortical spreading depression, that is thought to cause migraines. It can also reduce pain during a migraine attack by blocking pain-transmitting chemicals in the brain.

Cove offers 400 mg magnesium citrate, glycinate and oxide tablets. After working with leading headache specialists, we chose this formulation because it's easily absorbed, calming, and most likely to be effective.

Typically, if people get too much magnesium, their kidneys will just get rid of the excess in their urine. Still, you should not take magnesium supplements more often than indicated on the packaging unless directed by your doctor.
