Overview
Magnesium is a vital mineral that is crucial for the proper functioning of the human body, participating in over 300 metabolic reactions. Its wide-ranging benefits include reducing stress, preventing cramps and protecting against bone demineralization.
A deficiency in magnesium can manifest through symptoms such as twitching, cramping, loss of appetite, nausea, impaired cognitive function, fatigue, weakness, and irregular heart rhythms.
To promote optimal health, it’s advised that men consume 420 mg and women consume 320 mg of magnesium daily. Thankfully, these intakes can be easily met through dietary choices, with vegetables emerging as notable contributors among various food groups.
This article delves into the world of magnesium-rich vegetables, highlighting the top 12 sources that can help you meet your daily magnesium needs.

1. Spinach
Spinach tops the list of magnesium-rich vegetables, with an impressive 157 mg per 1-cup serving, which equates to 37% of the Daily Value (DV). Beyond their rich magnesium content, these dark, wrinkled greens are a nutritional powerhouse, providing essential nutrients such as iron, vitamin K, vitamin A, manganese and folate.
Additionally, spinach offers a plant-based source of omega-3 fatty acids, particularly in the form of alpha-linolenic acid (ALA). Although not as concentrated as in fish or seeds, including spinach in your diet provides a boost of these essential fatty acids, which contribute significantly to enhancing both heart and cognitive function.
Spinach is more than just a leafy green; it’s a vision booster too. Packed with the antioxidants lutein and zeaxanthin, spinach contributes to promote and protect eye health. These compounds are known to accumulate in the retina, where they help filter harmful high-energy light and protect against oxidative stress.
Furthermore, spinach is considered an excellent source of iron and folate, making it a valuable addition to a diet aimed at preventing or treating anemia. Iron is crucial for the production of red blood cells, while folate supports their maturation.
2. Swiss chard
Swiss chard, a vibrant member of the Goosefoot family alongside spinach and beets, is not only visually striking with its bright stems but also a nutritional powerhouse. These colorful leaves offer a diverse array of nutrients, making Swiss chard a low-calorie and weight-loss friendly addition to your diet.
In terms of nutrition, a one-cup serving of cooked Swiss chard provides 36% of the recommended magnesium intake. This serving size also meets your daily needs for vitamins K and A, nearly half of vitamin C, and substantial portions of potassium, calcium, iron, and vitamin E.
What's more, Swiss chard has a remarkable array of antioxidants, including alpha and beta carotene, vitamins C and E, and polyphenols and flavonoids. These potent antioxidants play a crucial role in boosting the body's antioxidant capacity and immune system, as well as reducing the risk of certain cancers and neurodegenerative diseases.
3. Beet Greens
Beet greens have a texture similar to chard and spinach, and their nutritional profile rivals that of beets. One cup of these vibrant greens (144 grams) provides an impressive 98 mg of magnesium, or 23% of the DV.
As part of the league of dark leafy greens, beet greens contribute significantly to bone health, with the same serving size reportedly providing a staggering 581% of the DV for vitamin K, an essential mineral that plays a crucial role in preserving bone mass by securing calcium molecules within the bones.
4. Acorn Squash
Acorn squash, a winter variety known for its distinctive longitudinal ridges and sweet yellow-orange flesh, stands out not only for its delightful sweetness but also as a nutritional powerhouse. Packed with a myriad of vitamins, minerals, and plant compounds, acorn squash significantly contributes to overall health.
Magnesium abounds in acorn squash, as a one-cup (205 grams) serving delivers 88 mg, covering 21% of the recommended daily intake.
In the same acorn squash family, butternut squash appears to be another promising option for squash lovers, providing up to 14% of the DV in a comparable serving.
5. Artichokes
Often mistaken for a vegetable, the artichoke is, in fact, a type of thistle, and it brings more to the table than just its unique flavor.
Beyond their culinary use, artichokes have long been recognized for their potential medicinal benefits. Regular consumption of these earthy thistles can help with various aspects of health. They’ve been linked to potential reductions in blood sugar levels, improved digestion, lowered LDL cholesterol, and support for liver and heart health.

Okra is a flowering pod-shaped plant that is commonly referred to as “Lady’s Fingers” in many English-speaking countries. Okra is renowned for its potent antioxidant activity, low-calorie content, and distinctive flavor. It also contains key nutrients, including magnesium, manganese, and vitamin K.
For example, a one-cup (160-gram) serving of cooked okra would provide 14% of the recommended daily intake of magnesium, 29% of vitamin C, 53% of vitamin K, and 20% of manganese.
8. Kale
Kale is a very nutritious and versatile vegetable that is high in important minerals, vitamins, and antioxidants while being low calories. This cruciferous gem has around 33 mg of magnesium per 100 grams serving, accounting for 8% of the DV.

9. Potato and sweet potato
Potatoes and sweet potatoes, while distinct in flavor and appearance, share common nutritional benefits. Both are good sources of essential nutrients, including magnesium, though the exact content may vary based on factors like variety and preparation.
According to the USDA data, one medium sweet potato (114-gram) contains around 31 mg of magnesium. On the other hand, a similar regular potato (173-gram) has about 46 mg.
Regular potatoes, versatile and widely consumed, provide a filling dose of carbohydrates, potassium, and vitamin C. On the flip side, sweet potatoes boast a vibrant orange hue indicative of their high beta-carotene content, contributing to a rich supply of vitamin A. Additionally, sweet potatoes offer a slightly sweet taste and a significant amount of dietary fiber.
10. Collard greens
Collard greens are best known for their solid nutritional profile, particularly rich in vitamins and minerals. They are an excellent source of vitamin A, vitamin C, vitamin K and folate. Additionally, collard greens are known for their high fiber content, which benefits digestive health.
These nutrient-packed greens also contain magnesium, with one cup serving providing approximately 40 mg of this essential mineral. Their versatility in cooking, often used in Southern cuisine and various international dishes, also adds to their popularity.
11. Brussels sprouts
Brussels sprouts, often thought of as miniature cabbages, are another magnesium-rich cruciferous vegetable that provides about 23 mg of magnesium per cup as well as a powerful, unique flavor to enrich your culinary experience.
Beyond their richness in magnesium, Brussels sprouts are like a mine of vitamins, notably vitamin C and vitamin K, which greatly contribute to supporting the immune system and bone health. They're also recognized for their potential cancer-fighting properties due to antioxidants and sulfur-containing compounds.
