Magnesium is an important mineral for the nervous system, muscles, and bones. Many familiar leafy green vegetables still provide a significant amount of magnesium, helping to supplement the body's natural nutrition...
Magnesium is an essential mineral involved in over 300 biochemical reactions in the body. It plays a crucial role in the functioning of the nervous system, muscle function, heart rhythm, blood sugar control, and maintaining bone structure. According to nutritional recommendations for adults, the daily magnesium requirement is approximately 310-360 mg for women and 400-420 mg for men, depending on age and health status.
Magnesium deficiency can cause a number of symptoms such as fatigue, muscle cramps, sleep disturbances, decreased concentration, or an increased risk of metabolic disorders. Meanwhile, supplementing magnesium from natural foods is generally recommended over the overuse of supplements.
Leafy green vegetables are one of the best natural sources of magnesium, easy to prepare, and suitable for daily meals. Here are 5 magnesium-rich green vegetables you can add to your diet:
1. Rainbow chard – a rich source of magnesium among leafy vegetables.
Swiss chard is one of the leafy green vegetables that is rich in magnesium.
Swiss chard is one of the leafy green vegetables that is rich in magnesium. Just one cup of cooked Swiss chard contains about 150 mg – a relatively high amount of magnesium compared to many other vegetables.
This vegetable has large leaves and thick stems, and is usually red, yellow, or purple. When cooked, the stems and leaves can cook at different rates, so many people separate them for cooking. In addition to magnesium, rainbow chard also contains vitamin A, vitamin C, and antioxidants that are beneficial for the immune system.
However, rainbow chard also contains oxalates, a compound that can reduce the absorption of certain minerals such as calcium and magnesium. Studies show that boiling the vegetable can reduce its content. The significant oxalate content helps the body absorb minerals better compared to steaming or baking.
2. Spinach
Spinach is rich in magnesium.
Spinach is a popular leafy green vegetable in many cuisines . It is a food rich in magnesium, iron, folate, and vitamin K. One cup of cooked spinach contains approximately 87 mg of magnesium.
Spinach can be eaten raw in salads or cooked in many dishes such as soups, noodles, and stir-fries. When cooked, the vegetable reduces significantly in volume, helping to increase the amount of nutrients absorbed per serving.
Like kale, spinach also contains oxalates. Therefore, to balance nutrition, spinach should be combined with foods rich in vitamin C such as oranges, bell peppers, broccoli, or berries. Vitamin C helps increase iron absorption from vegetables.
Including a variety of magnesium-rich foods in your diet also helps ensure your body gets enough of this essential mineral.
3. Kale
Kale.
Kale belongs to the cruciferous vegetable family. This vegetable provides many bioactive compounds called glucosinolates – substances that have been studied for their potential to help prevent certain chronic diseases. One cup of cooked kale contains approximately 38 mg of magnesium.
Besides magnesium, kale is also rich in calcium and vitamin K, two nutrients important for bone health. In traditional cuisine in many countries, kale is often cooked in soups, boiled, or stewed until tender. The leaf veins are quite thick, so they are sometimes separated for longer cooking times. Some people add apple cider vinegar or lemon juice during preparation to enhance the flavor and make the dish more palatable.
4. Bok choy

Bok choy is a mild-flavored vegetable with a high water content and is easy to prepare in many dishes such as soups, stir-fries, or stews. Compared to some other leafy green vegetables, bok choy contains less oxalate, so the body can absorb calcium and magnesium from it more easily. One cup of cooked bok choy contains approximately 34 mg of magnesium.
Besides magnesium, bok choy also provides vitamin C, vitamin A, and antioxidants. These nutrients play a role in supporting immunity and protecting cells. When cooking, you can cut the bok choy in half lengthwise and lightly pan-fry it to maintain its crispness and minimize nutrient loss.
5. Mustard greens
Chinese cabbage.
Mustard greens are a familiar vegetable in many Asian cuisines, including Vietnam. This vegetable has a slightly spicy taste and a distinctive aroma. Mustard greens contain many plant compounds with anti-inflammatory and antioxidant effects, contributing to cardiovascular health and the immune system.
One cup of boiled mustard greens contains approximately 18 mg of magnesium. While the magnesium content in mustard greens is lower than some other vegetables, when combined with other magnesium-rich foods such as beans, nuts, and whole grains, it still contributes significantly to the total magnesium intake in the diet.
If you're not used to the mild spiciness of mustard greens, you can cook them longer or combine them with other ingredients to mellow the flavor.
Magnesium is found in many foods such as leafy green vegetables, legumes, seeds and nuts, whole grains, fish, and some seafood. Therefore, it is recommended to prioritize magnesium intake from natural foods before considering supplements. Eating a diverse diet not only provides magnesium but also many other vitamins, minerals, and antioxidants beneficial to health. In addition, to ensure optimal mineral absorption, maintain a balanced diet, limit processed foods, and ensure adequate exercise and sleep.
In cases of suspected persistent magnesium deficiency symptoms such as frequent muscle cramps, fatigue, or irregular heartbeat, people should seek medical advice and appropriate nutritional assessment.
