Do You Get Menstrual Migraines?

Do your headaches show up like clockwork right before your period starts? And they’re not just any headache—they’re the kind that throbs, makes light unbearable, and sometimes comes with nausea? Most likely, you're likely dealing with a menstrual migraine. As the founders of beeya, we know them well (they used to plague us, too).

When we dove into the research, we were surprised by just how common the connection between migraines and the menstrual cycle really is. More than half of women who experience migraines report that their attacks are linked to their period. In fact, menstrual migraine is one of the most common patterns of hormone-related migraine, yet it can still go unrecognized or undiagnosed. If this sounds familiar, we’re breaking down why menstrual migraines happen and what you can do about them.

Estrogen’s role in menstrual migraines

For context, menstrual migraines are triggered by the sharp drop in estrogen that happens in the late luteal phase, right before your period begins. It's not low estrogen itself that causes the problem. It's the speed of the decline. And because estrogen influences serotonin—and serotonin plays a key role in regulating pain—when estrogen drops steeply, serotonin drops with it. That sudden dip can cause blood vessels in the brain to constrict and then dilate rapidly. Enter: that characteristic pounding, throbbing migraine pain.

Estrogen also has anti-inflammatory properties, so when it falls, your body loses some of that protective buffer. Inflammatory prostaglandins (the same ones we talked about in our cramps newsletter) increase, and inflammation in the brain and surrounding tissues can contribute to migraine severity.

How magnesium impacts headaches

There's a magnesium piece here, too. Magnesium levels tend to dip during the late luteal phase and menstruation, and low magnesium has been consistently linked to migraine susceptibility. Magnesium helps regulate blood vessel tone, supports nerve function, and reduces the inflammatory response—all of which are directly involved in whether a migraine takes hold. So you've got not just one but three things converging at once: a steep estrogen drop pulling serotonin down with it, rising inflammatory prostaglandins, and depleted magnesium. It’s the perfect storm.

Other factors that make them worse

The hormonal shift is the primary driver, but a few things can make the threshold lower and the migraines more frequent or intense:

1. Blood sugar instability - This one comes up in nearly every newsletter we write because it touches everything! Blood sugar crashes trigger cortisol and adrenaline release, which can act as migraine triggers on their own. During the luteal phase, when insulin resistance is already slightly higher, skipping meals or going too long without eating makes this significantly worse.

2. Dehydration - Even mild dehydration can trigger migraines in susceptible people. Your brain is roughly 75% water, and when hydration drops, brain volume can temporarily decrease, pulling away from the skull and triggering pain receptors. Pair that with the estrogen withdrawal happening at the same time and you've got a recipe for a brutal headache.

3. Poor sleep - Sleep disruption is both a trigger and a symptom of the late luteal phase (thanks to dropping progesterone). And inadequate sleep lowers your migraine threshold, meaning triggers that your brain could normally handle become enough to set one off.

4. Chronic stress - Elevated cortisol increases inflammation, disrupts blood vessel regulation, and depletes magnesium faster. If you're going into the late luteal phase already stressed and depleted, there's less runway before a migraine hits.

5. Histamine - This is a less commonly discussed factor, but estrogen and histamine have a bidirectional relationship. Estrogen can increase histamine release, and histamine can increase estrogen production. If your migraines worsen when you consume high-histamine foods (aged cheese, red wine, fermented foods, cured meats) in the days before your period, it's worth experimenting with reducing histamine-rich foods during that window.

What can help

Menstrual migraines respond best to a preventive approach rather than only treating them once they arrive. The goal is to make the estrogen drop less steep, keep inflammation lower, and make sure your brain has the nutrients it needs to handle the transition.

1. Magnesium—start now, not when the migraine hits. Consistent daily magnesium intake is one of the most well-supported preventive strategies for menstrual migraines. It helps regulate blood vessel tone, calms the nervous system, and reduces inflammatory prostaglandins. Studies show that regular magnesium supplementation can reduce both the frequency and severity of migraines. Our beeyavibe magnesium powder makes it easy to stay consistent!

2. Stabilize blood sugar aggressively in the late luteal phase. Eat every three to four hours. Don't skip breakfast. Make protein the anchor of every meal (25 grams minimum). Pair carbs with protein and fat. The fewer blood sugar crashes your body has to deal with during this window, the fewer additional triggers your brain is exposed to.

3. Stay on top of hydration. Increase your water intake in the days leading up to your period. Add a pinch of sea salt for electrolyte support (this mocktail is delicious). Eat water-rich foods like cucumber, watermelon, and citrus. If you notice migraines tend to hit on the first day of your period, front-loading hydration in the two to three days before can make a noticeable difference.

4. Omega-3 fatty acids. EPA and DHA (from fatty fish, walnuts, and flaxseeds) help manage inflammation and support healthy blood vessel function. Some research suggests that higher omega-3 intake is associated with fewer and less severe migraines. If you're seed cycling with us, your daily flaxseeds during the follicular phase are contributing omega-3s, and adding fatty fish 2-3x/week covers the rest.

5. B2 (riboflavin). Riboflavin has solid evidence behind it for migraine prevention. It supports mitochondrial energy production in brain cells, which may help the brain handle the metabolic demands of the hormonal shift more effectively. Eggs, dairy, almonds, spinach, and mushrooms are good food sources. Talk to your provider about whether adding a B2 supplement makes sense for you.

6. Reduce stimulation when you can. Bright lights, loud environments, strong smells, and screen time can all lower your migraine threshold. During the 2-3 days when you're most vulnerable, dimming your screens, wearing sunglasses outdoors, and giving yourself quieter mornings and evenings isn't key. When possible, go to bed earlier!

The mind-body piece worth trying

There's growing recognition that migraines aren't purely a physical event. They're deeply tied to your nervous system, and your nervous system is deeply tied to your emotional state. Repressed stress, unexpressed frustration, bottled-up resentment, etc. All of it gets stored in the body, and for many people, it shows up as pain. Migraines included.

One practice worth experimenting with: expressive journaling. Set a timer for 15-20 minutes and write freely about whatever feels heavy, stressful, or unresolved. Don't edit, don't filter, don't worry about it making sense. The point is to give those emotions somewhere to go besides your body. Research shows that this kind of writing can lower stress hormones, reduce inflammation, and improve pain outcomes. Some women notice a shift within weeks of making it a regular habit, especially in the days leading up to their period when the nervous system is already more reactive.

Your migraines are telling you something

If your migraines follow a predictable cyclical pattern, that's not bad luck. It's your body responding to a specific hormonal event, and it's giving you a clear window to intervene. You don't have to accept a handful of lost days every month. Start with magnesium, blood sugar regulation, and hydration. Track whether the pattern shifts over 2-3 cycles. And consider bringing the data to your provider! A migraine diary that maps to your cycle is some of the most useful information you can walk into an appointment with.
