A ranked list of the most practical, nutrient-dense magnesium foods widely available in the US, with serving sizes, absorption notes, and easy use cases.
Cooked spinach and pumpkin seeds deliver the highest magnesium per typical serving.
Beans and nuts provide magnesium plus protein, fiber, and heart-healthy fats.
Bioavailability is influenced by phytates and oxalates; simple prep methods can help.
Choosing diverse sources makes it easy to meet daily needs without supplements.
We ranked foods by: 1) magnesium per typical US serving, 2) practicality (nationwide availability, cost, convenience), 3) nutrient co-benefits (fiber, protein, healthy fats), and 4) absorption considerations (phytates/oxalates). Weighting: magnesium per serving 50%, practicality 25%, co-benefits 15%, absorption 10%. Fortified products and supplements were excluded.
Magnesium supports muscle function, heart rhythm, nerve signaling, and energy metabolism. Many Americans fall short of daily needs; focusing on high-yield, accessible foods helps close the gap efficiently.
Exceptional magnesium per common portion, very low calories, widely available fresh or frozen, and versatile in meals. Oxalates may modestly reduce absorption, but net intake from a full cup is still high.
Great for
High magnesium density in a small, portable portion; simple to sprinkle on salads, yogurt, or oatmeal. Phytates can reduce absorption somewhat; soaking or roasting can help.
Great for
Magnesium density and practicality drive the ranking: cooked spinach and pumpkin seeds deliver the most per typical portion with wide availability.
Phytates in seeds, nuts, and legumes can modestly reduce absorption. Simple methods like soaking beans, roasting seeds, and eating magnesium sources across meals help mitigate this.
Balancing calories matters: leafy greens and beans offer higher magnesium per calorie, while seeds, nuts, and chocolate pack more calories—portion control keeps intake efficient.
Diversity wins: combining greens, legumes, and small portions of nuts/seeds or dark chocolate makes meeting daily needs straightforward without relying on supplements.
Frequently Asked Questions
General recommendations are about 400–420 mg for adult men and 310–320 mg for adult women. Needs increase during pregnancy and may vary with medical conditions; consult a clinician if unsure.
It’s uncommon to reach harmful levels from food alone because the kidneys regulate excess. High-dose supplements can cause diarrhea or more serious issues; follow healthcare guidance for supplement use.
Magnesium is relatively stable to heat. However, boiling leafy greens can lead to some mineral loss into cooking water; use minimal water or consume the cooking liquid. Soaking and rinsing beans can reduce phytates and improve tolerance.
Phytates in seeds, nuts, and legumes can lower absorption somewhat. Very high intakes of calcium or zinc supplements may compete. Spreading magnesium-rich foods across meals and varied sources supports steady intake.
Most people can meet needs through food by including greens, legumes, nuts/seeds, and whole grains. Supplements may be appropriate for diagnosed deficiency or specific clinical cases; seek medical advice before starting.
To boost magnesium intake efficiently, prioritize cooked spinach and pumpkin seeds, then layer in beans, almonds, and a square of dark chocolate. Combine these across meals, use simple prep methods, and manage portions to meet daily needs comfortably.

Strong magnesium yield with protein, fiber, and potassium at a low cost. Available canned or dry nationwide. Soaking and rinsing reduce phytates and improve tolerance.
Great for
Reliable, portable source with healthy monounsaturated fats and vitamin E. Bioavailability can be moderated by phytates, but regular small portions contribute meaningfully.
Great for
Solid magnesium with polyphenols and flavor satisfaction. Higher cacao means more magnesium and less sugar. Best framed as a smart treat due to calories.
