Magnesium is an essential mineral that plays a vital role in numerous bodily functions, from maintaining nerve and muscle function to regulating blood pressure and supporting a healthy immune system. Despite its importance, many adults don’t get enough magnesium through their diet alone. Incorporating magnesium-rich foods into your daily meals is a delicious and effective way to boost your intake and reap the health benefits. Let’s explore the top food sources of magnesium and how this mineral contributes to your overall well-being.
Top 10 Magnesium-Rich Foods to Include in Your Diet
To ensure you’re getting enough of this crucial mineral, focus on including a variety of magnesium-rich foods in your diet. Here are ten excellent sources to consider:
1. Seeds: Tiny Powerhouses of Magnesium
Seeds, though small, are packed with nutrients, including a significant amount of magnesium. Adding seeds to your breakfast, snacks, or salads is an easy way to increase your magnesium intake.
- Pumpkin Seeds: A single ounce of pumpkin seeds provides a whopping 156 mg of magnesium, which is about 37% of the daily recommended value (DV). They are also a great source of zinc and healthy fats.
- Chia Seeds: Offering 111 mg of magnesium per ounce (26% DV), chia seeds are incredibly versatile. Sprinkle them on yogurt, blend them into smoothies, or use them to make chia seed pudding.
- Sunflower Seeds: While containing less magnesium than pumpkin and chia seeds, sunflower seeds still contribute a respectable 36 mg per ounce (9% DV). They are also rich in vitamin E and linoleic acid.
Seeds, in general, are excellent sources of fiber, protein, and unsaturated fats, making them a heart-healthy addition to any diet.

Nut butters, like peanut butter and almond butter, are also convenient ways to get your magnesium fix. Just two tablespoons of peanut butter contain the same amount of magnesium as a serving of whole peanuts. The unsaturated fats in nuts contribute to cardiovascular health, making them a smart dietary choice.
3. Beans: Legumes Loaded with Magnesium and More
Beans are nutritional powerhouses, offering a wealth of nutrients, including a good dose of magnesium. Incorporating beans into your meals several times a week can significantly increase your magnesium intake.
- Lima Beans: Cooked lima beans stand out with 126 mg of magnesium per cup (30% DV), making them an exceptional source.

- Milk: One cup of milk contains 24-27 mg of magnesium (6% DV). Milk is well-known for its calcium content and also provides protein and potassium.
Dairy products are among the best sources of calcium and contribute to your daily protein and potassium intake.
10. Dark Chocolate: A Deliciously Indulgent Magnesium Source
Dark chocolate is not only a treat but also a surprisingly good source of magnesium, especially varieties with a higher cocoa content.
- Dark Chocolate (70-85% Cacao): One ounce of dark chocolate with 70% to 85% cacao solids provides approximately 64.6 mg of magnesium, about 20% of the daily recommended amount for a 35-year-old woman.
Dark chocolate is made from cocoa beans, which are rich in beneficial plant compounds called flavonoids. Flavonoids may have anti-inflammatory properties and may help protect against heart disease and certain cancers. The higher the cocoa content, the more flavonoids and magnesium you’ll find in your dark chocolate.
Magnesium-Rich Beverages to Hydrate and Nourish
In addition to foods, certain beverages can also contribute to your daily magnesium intake:

- Heart attack and stroke
- Type 2 diabetes
- Osteoporosis
- Migraine headaches
- Asthma (in children)
- Certain cancers
While more research is needed, the evidence highlights the importance of magnesium for long-term health.
Magnesium Supplementation: When Diet Isn’t Enough
While obtaining magnesium from food is ideal, supplements may be necessary for some individuals to meet their daily requirements.
Recommended Daily Allowance of Magnesium (RDA):
| Age | Male | Female | Pregnancy |
|---|---|---|---|
| 19-30 | 400 mg | 310 mg | 350 mg |
| 31-50 | 420 mg | 320 mg | 360 mg |
| 51+ | 420 mg | 320 mg | 360 mg |
Types of Magnesium Supplements:
- Magnesium Citrate: Well-absorbed and often used for general magnesium supplementation and constipation relief.
- Magnesium Oxide: Commonly used for magnesium deficiency and constipation.
- Magnesium Chloride: Easily absorbed and may be beneficial for boosting magnesium levels and supporting prediabetes management.
Tolerable Upper Intake Levels (UL) for Magnesium Supplements:
| Age | Male | Female |
|---|---|---|
| 1-3 years | 65 mg | 65 mg |
| 4-8 years | 110 mg | 110 mg |
| 9-18 years | 350 mg | 350 mg |
| 19+ years | 350 mg | 350 mg |
Exceeding the UL for magnesium supplements can lead to side effects like diarrhea, dizziness, and in severe cases, heart arrhythmias. Consult with a healthcare provider before starting magnesium supplementation.
Improving Magnesium Absorption:
To optimize magnesium absorption:
- Avoid taking zinc supplements at the same time as magnesium.
- Choose magnesium citrate, lactate, or aspartate supplements for better absorption.
- Consider time-release magnesium supplements.
- Ensure adequate B vitamin intake, as vitamin B6 aids magnesium absorption.
