You’re probably tired. Not just "I stayed up too late watching Netflix" tired, but that deep, cellular dragging feeling that a third espresso can't quite fix. It might be the stress. It might be the lack of sleep. But honestly, there is a massive chance it is just a lack of magnesium.
Most people have no clue how to actually get magnesium in your diet without just swallowing a massive pill and hoping for the best.

It’s the "forgotten mineral." We obsess over protein macros and vitamin C during flu season, yet magnesium is quietly running over 300 biochemical reactions in your body right now. It helps your muscles relax. It keeps your heart rhythm steady. It even helps regulate your blood sugar. Despite all that, the USDA suggests about half of the US population isn't hitting their daily requirements.
The Soil Problem Nobody Likes to Talk About
Here is the frustrating reality: even if you eat your greens, you might be getting less than your grandparents did.
Modern intensive farming has sort of stripped the soil. We use fertilizers that prioritize yield and size over mineral density. A study published in the Journal of the American College of Nutrition compared USDA food composition data from 1950 and 1999. They found reliable declines in the amount of magnesium (and other minerals) in 43 different garden crops.
It’s not just you. It’s the dirt.
Because of this, you have to be more intentional. You can't just "eat healthy" and assume you're covered. You need to target specific, high-density sources and understand how your body actually absorbs the stuff.
Seeds and Nuts Are Your Secret Weapon
If you want the biggest bang for your buck, look at seeds.
Pumpkin seeds (pepitas) are basically the gold standard. A single ounce—roughly a small handful—contains about 150mg of magnesium. That’s nearly 40% of what an average adult needs in a day. It’s incredibly efficient.
Chia seeds are another heavy hitter. They aren't just for making weird pudding; they pack about 111mg per ounce.
Then you’ve got almonds and cashews. Cashews are great because they’re creamy and easy to snack on, providing roughly 80mg per ounce. But here’s the kicker: phytates. Many nuts and grains contain phytic acid, which can bind to minerals and prevent your gut from absorbing them. If you’re serious about getting magnesium in your diet, consider "activating" your nuts by soaking them or just ensuring you have enough vitamin D, which helps with overall mineral transport.
The Leafy Green Logic
We’ve all been told to eat our spinach. Popeye was onto something, but maybe not for the reasons he thought.
Magnesium is the central atom in the chlorophyll molecule. Basically, if it’s green, it has magnesium. Spinach, Swiss chard, and kale are your primary sources here. One cup of cooked spinach delivers about 157mg.
Why cooked?
Volume. You can eat a massive pile of cooked spinach much easier than a mountain of raw leaves. Plus, cooking can help break down some of those oxalic acids that might interfere with absorption.
Can You Eat Chocolate for Health? Sorta.
This is the one everyone loves to hear. Dark chocolate is genuinely high in magnesium.
A 100-gram bar of 70-85% dark chocolate has about 230mg of magnesium. That is huge. But let’s be real—eating an entire large bar of dark chocolate every day isn't exactly a "health hack" due to the sugar and calorie content.
Stick to a square or two of the darkest stuff you can find. The darker it is, the more mineral-rich cacao you’re getting and the less filler sugar you’re dealing with. It’s a legitimate way to boost your levels while satisfying a craving.
Don't Forget the Beans
Legumes are the unsung heroes of the pantry.
- Black beans: About 120mg per cup.
- Edamame: Roughly 100mg per cup.
- Lentils: About 70mg per cup.
They are cheap. They last forever. They provide fiber. If you're trying to figure out how to get magnesium in your diet on a budget, beans are the answer.
The Absorption Thieves
You could be eating all the pumpkin seeds in the world and still be deficient if you’re "leaking" magnesium.

Alcohol is a major culprit. It’s a diuretic, and it specifically signals your kidneys to dump magnesium. If you have a few drinks, you’re essentially flushing your mineral stores down the toilet.
High sugar intake does the same thing. Processing sugar requires magnesium, and it also increases urinary excretion. Then you have phosphoric acid in sodas, which binds to magnesium in the digestive tract, making it unavailable.
Basically, the "Standard American Diet" is a magnesium-depleting machine.
Water: The Missing Link
Not all water is created equal.
Depending on where you live, your tap water might be "hard." That usually means it has a high mineral content, including magnesium and calcium. In some regions, drinking two liters of tap water can provide up to 100mg of magnesium.
However, if you use a reverse osmosis filter or a water softener, you’re stripping those minerals out. If you use those systems, you might want to add mineral drops back into your water. It’s a simple way to passively increase your intake throughout the day without thinking about it.
Is Supplementing Necessary?
Sometimes, food isn't enough.
If you’re dealing with chronic stress, your body uses magnesium faster. Adrenaline and cortisol production are "expensive" in terms of mineral cost.
If you decide to supplement, don't just grab the first bottle you see. Magnesium Oxide is common and cheap, but it has terrible bioavailability—only about 4% is actually absorbed. It mostly just acts as a laxative.
Look for:
- Magnesium Glycinate: Highly absorbable and less likely to cause digestive upset. Great for sleep.
- Magnesium Citrate: Decently absorbed, but can have a mild laxative effect.
- Magnesium Malate: Often recommended for people with fatigue or muscle soreness.
Always check with a doctor like Dr. Rhonda Patrick or a functional medicine expert who understands mineral balance before dumping high doses into your system, especially if you have kidney issues.
Real-World Action Steps
Stop overcomplicating it. You don't need a gourmet chef to fix a deficiency.
Start by swapping your morning cereal for oatmeal topped with pumpkin seeds and chia seeds. That’s a massive magnesium hit before 9 AM.
At lunch, throw a handful of spinach into whatever you’re eating. It wilts down to almost nothing, so you won't even notice the texture change in a soup or stir-fry.
Replace your afternoon soda with sparkling mineral water. Brands like Gerolsteiner are famously high in naturally occurring minerals.
Finally, check your medications. Some common drugs, like Proton Pump Inhibitors (PPIs) for acid reflux, are notorious for blocking magnesium absorption over the long term. If you're on those, your diet needs to be even more dialed in.

Focus on whole, unprocessed foods. If it comes in a box with a long list of ingredients, the magnesium has probably been processed out. Stick to the edges of the grocery store—the produce, the bulk bins, and the fish counter.
Getting your magnesium levels right won't change your life overnight, but in a few weeks, you might just notice that the "unexplained" muscle twitches are gone and you're actually waking up feeling refreshed for once.
Immediate Next Steps for Better Magnesium Intake:
- Audit your snacks: Swap crackers or chips for an ounce of dry-roasted almonds or pumpkin seeds today.
- Go green at dinner: Add one cup of cooked Swiss chard or spinach to your evening meal to immediately net over 100mg of magnesium.
- Check your water: If you use a heavy filtration system, look into trace mineral drops to restore the magnesium removed during filtration.
- Watch the "thieves": Limit processed sugar and alcohol for the next 48 hours to allow your body to retain the minerals you are consuming.
