Top Magnesium-Rich Foods to Add to Your Diet

The top magnesium-rich foods include pumpkin seeds, chia seeds, almonds, cashews, spinach, Swiss chard, black beans, lentils, edamame, dark chocolate, avocado, yoghurt, and salmon. However, the same food can feel like it works for one person and does nothing for another, depending on portion size, how often you eat it, what else is on your plate, and even how you cook it.

Here is your complete list of magnesium-rich foods with realistic serving sizes and practical tips.

Daily targets

Most adults do well with 7-10 mg of magnesium per kg of body weight per day. If you're healthy with no obvious issues, aim for the lower end. If you're experiencing symptoms, training hard, or under significant stress, aim for the higher end. For specific guidance, see our magnesium dosage guide.

"Per 100g" numbers can mislead — use portions instead.

Food databases list magnesium per 100g, but nobody eats that way. Cocoa powder shows 430 mg per 100g, which sounds extraordinary - but 100g is three-quarters of a cup of pure cocoa. A realistic serving of 1-2 tablespoons gives you 25-50 mg. Pumpkin seeds show 550 mg per 100g, but a typical snack is 28g, which gives you 150 mg. Throughout this guide, all figures use realistic serving sizes.

Even with a clean diet, you can still fall short on magnesium. There are a few very common reasons this happens.

Soil depletion. Modern farming practices have depleted soil quality over the past 50-70 years, meaning the produce you buy today can contain less magnesium than the same foods did decades ago, even if you're eating well. This is documented across multiple agricultural studies.

Refined grains. As noted above, white rice, white bread, and regular pasta lose 75-90% of their magnesium during processing. If these are staples in your diet, you may be missing a major magnesium source without realising it.

Calcium-magnesium imbalance. Many people focus heavily on calcium for bone health — through dairy, fortified foods, and supplements — but neglect magnesium. Too much calcium relative to magnesium can interfere with absorption.

Higher demand from lifestyle. Stress, hard training, and regular alcohol consumption all increase your magnesium needs. If you're highly active or chronically stressed, your body burns through magnesium faster than someone living a lower-demand lifestyle. For more on this, see our guide on magnesium deficiency symptoms.

Relying on one "superfood" and quitting after a few days.

Someone learns that pumpkin seeds are high in magnesium, goes all-in for a few days, then gets sick of them and drops the whole idea. The issue isn't pumpkin seeds - it's the "one food will save me" mindset. Magnesium intake is a weekly habit, and when your strategy depends on a single food, you've basically built your plan on boredom.

The fix: Rotate your magnesium sources across categories - nuts and seeds, leafy greens, legumes, whole grains, and dark chocolate. Build a system where you can swap one source for another without restarting your diet every week.

Ultra-processed "health" foods that crowd out real food.

Protein bars, meal replacement shakes, flavoured yoghurts, and fortified cereals may seem like responsible choices. But the bigger issue is what they replace. When these become daily staples, they crowd out the foods that naturally carry magnesium alongside fibre, water, and a richer nutrient profile.

Fortified doesn't always mean absorbed, either. Magnesium is one of those nutrients where your gut environment plays a large role. If your overall diet is low in fibre or heavy in additives, your digestion can undermine absorption even when you're technically consuming enough.

The fix: Prioritise whole foods first. A bowl with beans, greens, and whole grains will do more for you long-term than relying on bars and shakes.

Ignoring the basics: sleep, hydration, and sufficient calories.

If you're under-eating, dehydrated, or sleep-deprived, your magnesium needs go up while your body becomes less efficient at using what it gets. Under-eating is especially common. When calories drop too low, magnesium intake usually drops with it, and stress hormones can rise - amplifying the symptoms you're trying to fix.

Hydration matters too. Magnesium works closely with electrolytes, and dehydration can throw off balance and amplify symptoms like fatigue, headaches, or cramps. Sleep is where your body does most of its repair work. If sleep is consistently poor, the whole "supplement one thing and feel great" expectation becomes unrealistic.

The fix: Hit your calorie needs, drink enough water, and prioritise 7-8 hours of sleep. Fixing the basics makes magnesium strategies work better, not just "more."

Sometimes diet alone doesn't cut it. Supplementation makes practical sense in a few scenarios:

• Diagnosed deficiency or clear symptoms — if you're noticing the classic signs that match magnesium deficiency symptoms, waiting for food alone to fix it is slow.
• Athletes and highly active people — training increases demand, and you can burn through magnesium faster than food intake replaces it. See our guide on magnesium for exercise.
• Absorption issues — if digestive problems impair absorption, you can eat all the right foods and still fall short.
• Specific health conditions — conditions such as migraines or high blood pressure are contexts where magnesium is commonly part of the discussion.
• Restricted diets — dairy-free, grain-free, or nut-free diets remove several of the easiest food sources, making it harder to hit targets consistently.
