About 48% of Americans do not get enough magnesium, according to National Institutes of Health fact sheets summarizing U.S. intake data. That gap matters because magnesium supports nerve function, muscle relaxation, and sleep-related body processes, the NIH stated. Here are 10 food-first tips built around common grocery items sold nationwide.
1. Add pumpkin seeds to an evening snack
A 1-ounce serving of pumpkin seeds provides about 156 milligrams of magnesium, according to the National Institutes of Health Office of Dietary Supplements. That makes it one of the most concentrated common food sources in a small portion.
Try them around 7 or 8 p.m. as part of a simple snack instead of heavily salted chips. The USDA lists roasted pumpkin seeds as a widely available pantry food, and the crunch makes them easy to pair with fruit.
2. Build dinner around cooked spinach
A half-cup of boiled spinach contains about 78 milligrams of magnesium, per NIH data. Spinach also delivers folate and potassium, two nutrients often discussed in USDA dietary guidance.
A practical option is folding spinach into pasta, soup, or eggs at dinner. Frozen spinach is sold in most U.S. supermarkets year-round, and it usually costs less per ounce than fresh bunches.
3. Use black beans in tacos, bowls, or soups
A half-cup of black beans offers roughly 60 milligrams of magnesium, according to the NIH. Beans also provide fiber, which the FDA notes most Americans do not get enough of.
Black beans fit easily into weeknight meals in Texas, California, or New York without changing much else on the plate. Canned versions are common nationwide, and lower-sodium labels are easy to find.
4. Keep almonds on hand for a steady snack
One ounce of dry roasted almonds has about 80 milligrams of magnesium, per the NIH Office of Dietary Supplements. That serving is roughly 23 almonds, a portion many people can estimate without a scale.
Almonds also bring protein and unsaturated fat, according to USDA nutrition data. Eating a measured handful in the evening may feel more satisfying than sweets that add sugar close to bedtime.
5. Choose plain yogurt with magnesium pairings
Yogurt is not the highest magnesium food, but an 8-ounce serving of plain low-fat yogurt contains about 42 milligrams, according to USDA FoodData Central. It also supplies calcium and protein.
Pair it with pumpkin seeds or sliced banana to raise the total magnesium in one bowl. That combination can work as a 9 p.m. snack that feels light but still substantial.
6. Try oatmeal as a late dinner or bedtime bite
One cup of cooked oatmeal provides about 63 milligrams of magnesium, according to USDA nutrition data. Oats are also a whole grain, which the 2020-2025 Dietary Guidelines for Americans recommends emphasizing.
For a calmer evening routine, keep toppings simple and lower in added sugar. Bananas, almonds, or peanut butter can raise magnesium without turning one bowl into a dessert-heavy meal.
7. Work avocado into toast, salads, or rice bowls
One medium avocado contains about 58 milligrams of magnesium, according to NIH food tables. Avocados are also a source of fiber and monounsaturated fat, which USDA guidance includes in healthy eating patterns.
In states like California and Florida, avocados are especially common in stores, but they are sold nationally all year. A half avocado at dinner is an easy way to add magnesium without much prep.
8. Pick edamame for a simple freezer staple
A half-cup of shelled edamame provides about 50 milligrams of magnesium, according to NIH data. It also contains protein, making it useful for people who want a more filling evening snack.
Frozen edamame is stocked in many major chains from Kroger to Safeway. A quick microwave serving with light seasoning takes about 5 minutes and adds a measurable amount of magnesium.
9. Use dark chocolate carefully, not heavily
One ounce of dark chocolate with 70% to 85% cacao contains about 64 milligrams of magnesium, according to the NIH. It can fit into a magnesium-focused diet, but portion size still matters.
The FDA recommends paying attention to added sugar and total calories on packaged foods. A small square after dinner can add magnesium without replacing more nutrient-dense staples like beans or greens.
10. Make tofu part of a regular dinner rotation
A 3.5-ounce serving of firm tofu contains about 35 milligrams of magnesium, according to USDA FoodData Central. Tofu also supplies protein and is widely available in refrigerated sections across the U.S.
Stir-fries, grain bowls, and soups make tofu easy to use once or twice a week. The NIH states food sources are generally preferred for routine magnesium intake unless a clinician recommends supplements.
