Hi, friends!
If you’ve been waking up tired, snapping at your fiancé over nothing, craving chocolate like a banshee, or lying in bed wired but exhausted… it might not be your period, your job, or your zodiac sign. It could be magnesium. Yes, really. This overlooked mineral is working overtime behind the scenes—regulating your mood, sleep, hormones, stress, blood sugar, and more, and if you’re even a little deficient (spoiler: most women are), your body will start waving red flags fast. I'm talking weepy, snappy, crampy chaos. So let’s get real about why magnesium needs to be on your radar every single day.
Short Answer: Why you need magnesium every single day:
It supports over 300 biochemical reactions in your body, which is mind-blowing if you stop to think about it.
It helps regulate mood, sleep, stress, hormones, muscles, blood sugar, and so much more.
Deficiency is shockingly common, especially among women like us.
If you’re constantly stressed, glued to coffee, eating anything that comes in a box, or sweating it out like it’s your full-time job, your magnesium levels are probably in the trash. Cramps? Random anxiety? Sugar cravings that hit at 9 PM on the dot? That annoying 3 AM wake-up? Yeah. Magnesium might be behind all of it. I’ll explain it in real-human terms, zero science lecture. Plus, I’ll share the magnesium I use!
Magnesium for Your Mind
Something that blew my mind when I first learned about it: Magnesium is like rocket fuel for your brain. Seriously, let me break it down for you.
So, magnesium plays a crucial role in regulating neurotransmitters, those essential brain chemicals that decide how we feel, whether we’re cruising along in a calm state or caught up in a chaotic whirlwind of thoughts and anxiety. Imagine it as a balance, where magnesium helps modulate GABA, often called the brain’s chill switch, and glutamate, which is more like the brain’s gas pedal.
What’s fascinating is that magnesium is tied to our cognitive functions. It supports key areas like memory, learning, and focus, essentially everything that helps us navigate daily life effectively. If you’ve ever experienced that cloudy, frazzled feeling in your mind, it could very well be that you’re not getting enough magnesium.
Our brains are constantly working hard, processing information, and dealing with stress. Without adequate magnesium, this vital organ can struggle to keep up. So, if you’re finding it hard to concentrate or retain information, magnesium might just be the missing link. Incorporating magnesium-rich foods into your diet or even considering supplements could really make a difference.
Real-life benefits:
Less anxiety spiraling over texts you sent 4 days ago.
Falling asleep faster instead of mentally rearranging your living room at 2 a.m.
Better focus without having to chug 3 coffees and still feeling like a raccoon with a deadline.
I notice a huge difference in my own mental clarity and calm when I stay consistent. It’s subtle, but when it’s gone? Chaos. It’s like the mental version of running out of dry shampoo. You can go without it, but at what cost?
💪 Magnesium for Your Body
Magnesium is basically the backstage manager of your whole body. It’s juggling jobs like:
Relaxing your muscles (including your uterus, which we’ll get into).
Keeping your blood pressure from creeping up like an ex in your DMs.
Regulating blood sugar to avoid that 3 p.m. crash-then-binge cycle.
If you work out:
Magnesium helps your muscles contract and relax properly. So if you’re sore forever after leg day, or you cramp up during Pilates like your limbs are rebelling, it’s not just age. It might be low magnesium. It also plays a role in energy production, so it helps you have the stamina to work out in the first place.
If you have PMS:
Listen. I have tried everything for cramps. But magnesium has helped me more than most prescriptions. It relaxes the uterine muscles (bless), so PMS symptoms like cramps, headaches, and bloating don’t turn into a full Greek tragedy.
If you deal with inflammation or blood sugar drama:
Chronic inflammation is at the root of so many issues: acne, fatigue, anxiety, and hormonal imbalances. Magnesium helps cool that fire down. It’s also been shown to improve insulin sensitivity and support blood sugar regulation, which is huge if you crash after meals or constantly crave sugar.
Magnesium for Your Skin & Beauty Routine
This is the tea nobody’s spilling on TikTok: Your skin needs magnesium.
Here’s why:
It has anti-inflammatory properties that help reduce redness, acne, and irritation.
It can help lower cortisol levels, which = fewer breakouts and puffiness.
It’s key for keeping your skin cells hydrated and functioning well.
When I’m on top of my magnesium, my skin looks brighter, smoother, and I swear my under-eyes aren’t as puffy. When I fall off, I get these tiny little flare-ups that scream, “you’re stressed and you don’t even know it yet.”
Plus, low magnesium has been linked to increased free radical damage (aka aging). So, if you’re investing in serums but ignoring minerals? Babe, you’re just moisturizing the symptoms. For more on this: How to Repair Your Skin Barrier (Without Having a Mental Breakdown in the Process)
The Different Types of Magnesium (And What They’re For)
There are many types of magnesium, and they all do slightly different things. Here's a cheat sheet:
Not all forms absorb equally, and some (like oxide) are basically garbage. If a product lists “magnesium oxide” and nothing else, skip it.

Here’s what’s in my rotation right now, and why I love them:
🛁 Magnesium Bath Flakes
My holy grail for winding down at night. These are basically Epsom salts on steroids. I throw them into a warm bath with a little lavender essential oil and soak until my soul floats. Perfect for sore muscles, cramps, and general life overload.
🥤 Jigsaw Health MagSoothe
A clean-girl bedtime staple. This tastes like raspberry lemonade and helps your nervous system chill without sketchy additives. It’s got magnesium glycinate (super gentle on the gut), and honestly? You’ll sleep deeper, wake up less puffy, and feel less like a stressed-out gremlin by morning.
How to Add Magnesium to Your Routine
You don’t need to overthink this. Here’s what works for most people:
Nighttime: Take magnesium glycinate 1-2 hours before bed (bonus: it helps with sleep and muscle relaxation).
Workout recovery: Use magnesium flakes in your bath post-sweat.
Daily beauty boost: Mix a hydration powder with magnesium into your morning water or tea.
PMS week: Double down with both topical (sprays, baths) and oral magnesium.
Start slow, listen to your body, and adjust. Some people feel the benefits in a few days. Others need a week or two of consistency. But when it does kick in? You’ll wonder how you ever lived without it.
✨Magnesium is THAT Girl
It’s wild that one mineral can do so much, and yet, most of us don’t even think about it. If you’re anxious, tired, crampy, breaking out, or just don’t feel like yourself... start here.
Magnesium supports your mind (calm, clarity, mood), your body (muscles, hormones, sleep), and your beauty (skin, hydration, inflammation). It’s not a cure-all, but it’s pretty close to a foundation. Once that’s in place, everything else works better.
So yes, magnesium is still invited to the Sleepy Girl Mocktail party. But now, she’s also headlining your beauty cabinet, your supplement drawer, and your stress toolbox!
