Magnesium deficiency often feels like persistent fatigue and weakness, coupled with symptoms like muscle cramps, spasms, and tremors, as well as nausea, loss of appetite, and headaches. More severe deficiency can lead to numbness, tingling, abnormal heart rhythms, personality changes, and even seizures, impacting nerves and heart function.
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.
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.
Some good sources of magnesium are:
For example, a magnesium deficiency causes nocturnal leg cramps in 5 to 30 per cent of pregnant women. Other symptoms include: Muscle cramps. Muscle spasms.
Early signs and symptoms of magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness. As magnesium deficiency worsens, numbness, tingling, muscle contractions and cramps, seizures, personality changes, abnormal heart rhythms, and coronary spasms can occur [1,2].
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.
Avocados: One whole avocado = 58 mg of magnesium. Bananas: One medium banana = 32 mg of magnesium. Papaya: One small papaya = 33 mg of magnesium. Blackberries: 1 cup = 29 mg of magnesium.
Common causes of low magnesium include:
The best magnesium supplement for pregnancy often depends on specific needs, with Magnesium Glycinate recommended for sleep/relaxation (gentle on stomach) and Magnesium Citrate for constipation relief due to high absorption, while Magnesium Bisglycinate is highly effective for pregnancy leg cramps, though always consult your doctor before starting any supplement. Magnesium is crucial, but aim for forms with high bioavailability like glycinate or citrate, as less absorbable forms like oxide aren't ideal for correcting deficiencies, and topical options (oils, Epsom salts) are great for cramps.
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.
These muscle cramps often occur in the calves. However, tension in the shoulder and neck area and eyelid twitching can also be signs of a magnesium deficiency. Cardiac arrhythmia, migraine attacks or tension headaches can also be caused by a lack of magnesium.
Magnesium (Mg) is involved in the regulation of metabolism and in the maintenance of the homeostasis of all the tissues, including the brain, where it harmonizes nerve signal transmission and preserves the integrity of the blood–brain barrier.
It also plays a role in the transportation of other electrolytes like calcium and potassium, which are responsible for nerve signalling and muscle contraction. Chest pain, breathlessness, dizziness, etc., can be caused by a lack of magnesium signs indicating irregular heartbeats.
For women especially, magnesium is important because it plays a role in hundreds of different functions involved in hormone regulation. Thankfully, increasing dietary magnesium intake and taking a daily supplement can reverse symptoms and optimize blood sugar levels, mood, sleep and menstrual cycles.
Achieving 100% of the daily recommended magnesium intake can be accomplished by eating foods rich in magnesium, such as:
The causes of magnesium deficiency include: Chronic diarrhea. Frequent vomiting. Malabsorption, due to a digestive condition, such as inflammatory bowel disease (IBD), or a procedure that removes part of the small intestine, namely weight loss surgery.
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.
Hypomagnesemia occurs with both loop diuretics (furosemide, bumetanide, torsemide, and ethacrynic acid) and thiazide diuretics (chlorothiazide, hydrochlorothiazide, indapamide, and metolazone).
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.
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.
Drinking enough water isn't always enough. Your body needs the right minerals to absorb and retain hydration properly. Magnesium is a key electrolyte that ensures efficient water absorption at a cellular level.
Magnesium-Rich Foods

Herbal Teas: Nettle tea, chamomile tea, and dandelion root tea are not only soothing but also magnesium-rich options. Mineral Water: Some mineral waters naturally contain magnesium.
