Magnesium is a vital mineral that supports many bodily functions, including muscle and nerve function, and blood pressure regulation [3]. Deficiency can have serious health consequences, and dietary changes can help prevent or correct the issue [2]. Focusing on whole, unprocessed foods is the most effective way to get enough.
Top Food Sources to Boost Your Magnesium Intake
Leafy Green Vegetables
Green, leafy vegetables are some of the most concentrated food sources of magnesium, with spinach being a particularly potent option [4]. Magnesium is a central component of chlorophyll, the pigment that gives these plants their color [3]. Cooking these vegetables can sometimes increase their magnesium content per serving [4].
- Spinach: A half-cup of boiled spinach provides a significant portion of the recommended daily value (DV) [3].
- Swiss chard: Swiss chard is an excellent source of magnesium and can be added to salads or sautéed [4].
- Beet greens: This green can be cooked and served as a nutritious side dish [4].
Nuts and Seeds
Nuts and seeds are convenient and powerful sources of magnesium [5].
- Pumpkin seeds: One ounce of roasted pumpkin seeds contains a high amount of magnesium [3].
- Chia seeds: An ounce of chia seeds provides a significant amount of magnesium and can be used in puddings or as a topping [3].
- Almonds: A one-ounce serving of dry-roasted almonds offers a good amount of magnesium [3].
- Cashews: Dry-roasted cashews are another great option [3].
Legumes
Legumes, including beans, lentils, and peas, are highly nutritious [6].
- Black beans: Cooked black beans contain a good amount of magnesium per half-cup serving [3].
- Edamame: A half-cup of shelled and cooked edamame provides magnesium [3].
- Lentils: These can be added to soups, stews, or salads [4].
Whole Grains
Unlike refined grains, whole grains retain their nutrient-rich bran and germ, which are high in magnesium [3].
- Brown rice: A half-cup of cooked brown rice contains magnesium [3].
- Whole wheat bread: One slice of whole wheat bread offers magnesium [3].
- Whole grain cereals: Many breakfast cereals are fortified with magnesium; check the nutrition label for content [3].
Other Excellent Sources
Several other foods are great for boosting magnesium intake.
- Dark chocolate: A one-ounce square of dark chocolate can contain magnesium [7].
- Avocado: A medium avocado is a good source of magnesium [5].
- Bananas: A medium banana contains magnesium [3].
- Salmon: A three-ounce serving of cooked Atlantic salmon offers magnesium [3].
- Tofu: Tofu can provide a substantial amount of magnesium [6].
Strategies for Maximum Absorption
To get the most out of your magnesium-rich foods, consider these tips:
- Pair with Vitamin D: Magnesium helps convert Vitamin D into its active form, and Vitamin D can help with magnesium absorption [8]. Eating magnesium-rich foods with a source of Vitamin D (like salmon) can be beneficial.
- Minimize Processed Foods: The refining process for grains and other foods removes a significant portion of their magnesium content [3]. Prioritize whole foods over processed options.
- Proper Cooking Methods: Steaming or baking vegetables helps to preserve their magnesium content more effectively than boiling, which can cause some of the mineral to leach into the water [5].

Conclusion: Making Magnesium-Rich Choices
Incorporating a variety of magnesium-rich foods is a simple way to support your overall health. By prioritizing nuts, seeds, legumes, and leafy greens, you can ensure your body receives the necessary magnesium for optimal function. Getting this essential mineral from a diverse diet of whole foods is the best approach, providing a full spectrum of nutrients [7]. Making mindful food choices, such as opting for whole grains over refined ones and snacking on nuts instead of chips, will naturally lead to higher magnesium intake over time.
