No, one banana a day isn't enough magnesium for most adults, as it provides only about 32-37 mg (around 8-9% of the Recommended Daily Intake, or RDI), while adults need 310-420 mg daily, so you need to eat many more magnesium-rich foods like leafy greens, nuts, seeds, legumes, and whole grains to meet your needs.
Achieving 100% of the daily recommended magnesium intake can be accomplished by eating foods rich in magnesium, such as:
Bananas are the richest fruit in magnesium. If eaten dried, its magnesium content is higher. More generally, dried fruits such as figs, dates and apricots are an important source of magnesium. Recipe idea: Try a banana-spinach smoothie.
Magnesium-Rich Foods
The relationship between magnesium supplements and heartburn is complex, with potential benefits and side effects to consider. While magnesium can aid digestion and may help alleviate heartburn symptoms for some, it can also cause discomfort in sensitive individuals, particularly when taken in certain forms or dosages.
Milk of magnesia (magnesium hydroxide) is a popular OTC acid reflux treatment. Dosage recommendations for adults are 5–15 milliliters (ml) at a time, which can be repeated up to 4 times daily as needed. The dose should not exceed more than 60 ml in any 24 hours.
Signs of low magnesium
For drinks high in magnesium, opt for mineral waters, fruit juices (especially orange, cherry, watermelon), plant-based milks (soy, almond), and homemade concoctions using raw cacao, coconut milk, or magnesium powders mixed with water or smoothies, with hot chocolate (made with raw cacao) and herbal teas (like nettle) also being good choices.
But some foods and drinks can make it harder for your body to absorb magnesium or even increase magnesium loss, so timing and pairing matter.
Good sources of magnesium include green leafy vegetables, legumes, nuts, seeds, whole grains, and certain beverages. Magnesium may also be added to some breakfast cereals and other fortified foods. In general, approximately 30% to 40% of the magnesium obtained from food and beverages is absorbed by the body.
Cantaloupe: 428 mg per cup. Spinach: 271 mg per cup, cooked. Asparagus: 271 mg per cup, cooked. Tomato: 292 mg per medium tomato.
Which form of magnesium is best? “The form — whether it's a capsule, powder or gummy — has a low impact on how the magnesium is absorbed,” Turke says. “What matters most is the type, dose and how often you take it.” In general, forms like citrate, glycinate and malate are absorbed better than oxide or sulfate.
It's recommended that you eat two servings of fruit per day as part of a healthy diet. Consider these to check that box plus the one for magnesium: Avocados: One whole avocado = 58 mg of magnesium. Bananas: One medium banana = 32 mg of magnesium.
"Little baby plants—if you can plant it and expect it to grow—like beans, nuts, seeds, and legumes are good sources of magnesium,” Boi says. “Peanut butter is also going to get you a lot of magnesium.” Leafy vegetables, meanwhile, include those with smaller leaves, like spinach.
A high-saturated fat diet reduces magnesium absorption in the intestines. High sugar intake increases excretion of magnesium by the kidneys. Phosphates found in carbonated beverages such as dark-colored sodas bind magnesium, rendering it unusable by the body.
Eat magnesium-rich foods – Include leafy green vegetables, legumes, nuts, seeds, whole grains like brown rice, bananas, and milk products in your daily diet.
And taking vitamin D in large doses can also deplete magnesium, leading to a magnesium deficiency — or making an existing one worse.
Your body needs magnesium to function normally. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms. A blood test or urine test can be used to diagnose magnesium deficiency. Magnesium deficiency is usually treated with supplements.
Yes, magnesium can help you sleep better by calming the nervous system, relaxing muscles, and supporting melatonin production, with some studies showing it improves sleep quality, duration, and efficiency, particularly for those with low levels or sleep issues like restless legs. While more research is needed, magnesium glycinate is often recommended for sleep due to its gentle absorption, and you can find it in foods like leafy greens, nuts, seeds, and whole grains, or as a supplement.
There's no questioning the health benefits of broccoli, but we're expanding the list by mentioning that it's an excellent magnesium food. Keep your heart healthy with one small stalk of broccoli, which packs not only 5 g of filling fiber but also a significant amount of magnesium: 29.4 mg for just 50 calories.
Culprit medications linked to hypomagnesemia include antibiotics (e.g. aminoglycosides, amphotericin B), diuretics, antineoplastic drugs (cisplatin and cetuximab), calcineurin inhibitors, and proton pump inhibitors.
