You may feel like you’ve been hearing a lot about how vitamins can help prevent migraines or even reduce the pain that comes along with the attacks. But which claims are real and which are just bogus?
We did the research for you and found out that magnesium is one of the few nutrients that are clinically proven to help cut down migraine frequency.
Here’s everything you need to know about this natural migraine treatment.
Let’s start with the basics. Magnesium is a mineral that you need to stay healthy, just like calcium or iron. Specifically, magnesium helps your body do things like regulate muscle and nerve function, keep your blood pressure normal, and make protein, bone, and DNA.
It’s found in many foods, as well as in supplement form.
The amount of magnesium a person should be getting depends on age and sex, but for adult men, the average recommended amount is around 400-420mg per day, and 310-320mg for women. Most people in the U.S. don’t get enough magnesium from their diets, but older men and teenage girls are especially likely to have low magnesium levels.
How can you tell if you’re not getting enough? Unless your magnesium deficiency is severe, you probably won’t be able to tell. Even blood tests reveal less than 2% of the full amount of magnesium in your body, because most of it is stored in bones and cells.
Symptoms of magnesium deficiency include: loss of appetite, fatigue, nausea, and weakness, which are all fairly easy to chalk up to a different cause. Migraine sufferers are especially likely to be lacking in 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.
How does it help? 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.
Research suggests that it’s especially helpful for people who have migraines with aura or menstrual migraines. Scientists believe it may help prevent aura by stopping your brain from producing the signals that cause it, but they aren’t quite sure why it’s so effective against menstrual migraines.
Magnesium isn’t just beneficial for migraineurs. People with the conditions listed below may also be helped by this powerful mineral.
By now you might be thinking that it’s a good idea to get more magnesium in your diet, so you may be wondering what you should eat to make that happen.
Foods that are rich in magnesium include:
Okay, you probably should eat more spinach, but that doesn’t mean you want to eat it every night. So, how else can you make sure you’re getting plenty of magnesium?
The answer, as you may’ve guessed, is supplements. Magnesium is included in many multivitamins and other dietary supplements. Even when the whole purpose of the supplement is to give you more magnesium, it’s usually still combined with other nutrients because it’s easier for your body to absorb it that way. The most easily-absorbed supplements combine magnesium with aspartate, chloride, citrate, glycinate, or lactate. If you’re taking magnesium for migraine prevention, you’ll typically want the dosage to between 400-500mg per day.
Magnesium supplements are relatively safe (even for pregnant women, so long as the dose isn’t higher than 400mg), but that doesn’t mean they’re for everyone. People with reduced kidney function or certain neurological disorders (such as myasthenia gravis) should not take magnesium without first discussing it with their doctor.
In addition, magnesium supplements can interfere with your body’s ability to absorb some medications, so talk to your doctor before starting if you’re taking any of these medications:
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.
Taking too much magnesium can cause stomach cramps, diarrhea, and nausea, and extremely high intake can cause irregular heartbeat and even cardiac arrest. That said, it’s very difficult for someone to accidentally take enough magnesium to induce the most severe side effects.
Prescription medications come with side effects, and everyone’s different when it comes to which side effects aren’t too bad and which are just too much. One of the advantages of magnesium is that it doesn’t come with as many side effects. But the flipside of that is that it also may not be as effective.
Yes, magnesium is usually safe to take with preventative or acute migraine medications, but it’s best to talk to your doctor if you have any questions.
So there you have it: everything you need to know about magnesium. That may have been a lot of information, but the main takeaway is that magnesium is a relatively safe way to reduce the frequency of your migraines, either on its own or in addition to other preventative medications.
