A practical, ranked guide to the highest-impact foods for boosting magnesium intake using per-serving amounts, bioavailability, and US accessibility.
Pumpkin seeds and cooked spinach deliver the most magnesium per common serving.
Beans and nuts add magnesium plus fiber, protein, and heart-healthy fats.
Dark chocolate is useful but best as an occasional, higher-cacao choice.
Cooking, soaking, or sprouting can modestly improve magnesium absorption.
Mix these foods across meals to reliably meet daily magnesium needs.
We ranked foods by magnesium per typical US serving (mg/serving), bioavailability (impact of oxalates/phytates and preparation), affordability, year-round grocery availability, and versatility in everyday meals. Values reflect commonly reported ranges from US food composition data; small brand-to-brand variations occur.
Magnesium supports energy metabolism, muscle and nerve function, blood pressure regulation, and bone health. Many Americans fall short of recommended intakes (roughly 310–320 mg/day for adult women and 400–420 mg/day for adult men). Choosing high-yield, accessible foods is a reliable way to close the gap.
Highest magnesium density per small serving; widely available and affordable; easy to add to meals and snacks. While seeds contain phytates, roasting/toasting and eating with vitamin C–rich foods may modestly improve absorption.
Great for
Very high magnesium per cooked cup and low cost. Spinach contains oxalates that can reduce absorption; cooking lowers oxalate content and improves practical yield. Easy to add to eggs, soups, and pasta.
Plant foods dominate magnesium sources; combining seeds, greens, beans, and nuts across meals is the simplest way to meet daily needs.
Preparation matters: cooking leafy greens and soaking/cooking legumes can reduce inhibitors like oxalates and phytates, modestly supporting absorption.
Affordability and availability are strong: canned beans, bagged spinach, and bulk seeds/nuts are year-round staples in US grocery stores.
Small portions add up: an ounce of seeds or nuts plus a cup of cooked greens can cover roughly half or more of many adults’ daily needs.
Frequently Asked Questions
Most adult women need about 310–320 mg/day and most adult men need about 400–420 mg/day. Needs rise during pregnancy and vary with age. Aim to spread intake across meals rather than relying on a single food.
Cooking leafy greens reduces oxalates; soaking and thoroughly cooking legumes reduces phytates; roasting seeds and nuts can help modestly. Pairing magnesium-rich foods with a varied meal pattern supports overall absorption.
It contributes, especially at 70–85% cacao, but serving sizes are small and sugar content varies. Treat it as a complementary source alongside seeds, greens, beans, and nuts.
Food-first is typically recommended because it delivers fiber and other nutrients. Supplements can help in specific situations; discuss your needs and possible interactions with a clinician before starting any supplement.
Top salads and oatmeal with pumpkin seeds or almonds, fold cooked spinach into eggs or pasta, add black beans to burritos, soups, and bowls, and enjoy a square of higher-cacao dark chocolate as a finishing touch.
To raise magnesium intake efficiently, anchor meals with pumpkin seeds, cooked spinach, black beans, and almonds, and use dark chocolate as a smart add-on. Plan simple, repeatable pairings—like a bean-and-spinach bowl topped with pepitas—to consistently meet daily needs without overhauling your routine.

Great for
Strong magnesium yield plus fiber and plant protein, excellent affordability, and consistent availability in canned and dry forms. Soaking and cooking reduce phytates, supporting absorption.
Great for
Dependable magnesium with healthy monounsaturated fats, good shelf life, and snack convenience. Phytates can slightly limit absorption; pairing with produce or fermented foods helps.
Great for
Respectable magnesium in small amounts and widely available. Higher cacao equals more magnesium but also varies in sugar; best used as a mindful addition rather than a primary source.
