To get 100% of your dietary magnesium, focus on a variety of whole foods like leafy greens (spinach, swiss chard), nuts (almonds, cashews), seeds (pumpkin, chia), legumes (black beans, edamame), whole grains (quinoa, brown rice), avocados, dark chocolate, and even fortified cereals, as magnesium is widespread in plants and absorbed well from fiber-rich foods, with some water and fortified options also contributing.
Achieving 100% of the daily recommended magnesium intake can be accomplished by eating foods rich in magnesium, such as:
Magnesium-Rich Foods
Yes, magnesium can cause headaches, but usually only when you have too much (hypermagnesemia) from high-dose supplements or impaired kidneys, while a deficiency in magnesium is a common cause of headaches and migraines, making magnesium supplementation a popular treatment for prevention. So, headaches can signal either too little or too much magnesium, depending on the context.
Fruit
Magnesium deficiency symptoms start mild with fatigue, weakness, loss of appetite, nausea, vomiting, and headaches, but progress to more severe issues like muscle cramps/spasms, numbness, tingling, anxiety, insomnia, abnormal heart rhythms, and even seizures, affecting nerve, muscle, and brain function crucial for overall health.
Magnesium is a mineral involved in hundreds of processes in our bodies. One of the things that it does is to help relax our muscles, so magnesium can be effective in promoting relaxation before sleep.
Individuals with diabetes, intestinal disease, heart disease, or kidney disease should avoid magnesium unless specifically instructed by their healthcare provider. Overdose: Signs of a magnesium overdose include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue.
Let's dive into the top 10 foods that block magnesium absorption.
Foods high in magnesium are leafy greens, legumes, nuts, seeds and whole grains. A doctor can check your magnesium levels by a blood or urine (pee) test. If you have low magnesium levels, your doctor may recommend taking a supplement.
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.
Almonds and cashews are rich in magnesium. One ounce of almonds contains 80 milligrams for 19% of the DV. Cashews are almost as good, with 74 milligrams for 18% of the DV.
To increase your intake of this essential nutrient, try incorporating magnesium-rich vegetables, like spinach, kale, acorn squash, edamame, artichokes, and parsnips, into your diet.
Very pure magnesium oxide is obtained from ore contain-ing magnesium, more particularly ore containing magnesium carbon-ate, by calcining the ore and leaching the resulting magnesium oxide with carbon dioxide and calcium chloride solution to produce magnesium chloride solution.
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.
Health Risks from Excessive Magnesium
Although the risk of acquiring too much magnesium from food is low among healthy people, high doses of magnesium from dietary supplements or medications can cause diarrhea, nausea, and abdominal cramping.
You should not mix magnesium with certain antibiotics (tetracyclines, fluoroquinolones), bisphosphonates, diuretics, proton pump inhibitors, some blood pressure drugs, and diabetes medications, as it can block absorption or alter effects, requiring spacing or avoidance. Also, separate magnesium from high doses of zinc, iron, calcium, and high-fiber/phytate/oxalate foods to prevent interference with absorption.
Magnesium for Energy Production and Fighting Fatigue
Magnesium can also reduce feelings of stress, which can drain energy reserves. Best Time to Take: Morning or early afternoon. Taking magnesium in the morning with breakfast or in the early afternoon helps you take advantage of its energizing effects.
Magnesium is a Necessary Nutrient but It Does Not Perform Miracles. Our body cannot function without magnesium, but that does not mean we require supplements of the mineral.
1. Magnesium glycinate: Best absorbed form, bonded to glycine amino acids, gentle on the stomach, ideal for muscle cramps and sleep support, and considered the safest form with the least side effects.
Dietary magnesium — an essential mineral found in foods like beans, nuts and spinach — influences blood pressure. High circulating levels of magnesium are associated with lower blood pressure, suggesting that magnesium deficiency, which is common, may contribute to the pathogenesis of hypertension.
Among the known magnesium deficiency causes are prescription medications such as diuretics, antibiotics, painkillers and cortisone, which can deplete magnesium levels in the body by impairing absorption or by increasing excretion by the kidneys.
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.
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.
