Magnesium deficiency can be diagnosed with a blood test and/or a urine test. If you have symptoms of magnesium deficiency or abnormal calcium or potassium levels, your doctor may refer you for a blood or urine test.
Magnesium deficiency is usually treated with magnesium supplements. Sometimes these can give you diarrhoea, so your doctor may need to adjust your dose. If your levels are very low, you may need magnesium through an intravenous (IV) drip in hospital.
If you are considering taking a magnesium supplement, speak to your doctor or pharmacist first, to make sure it's right for you.
Read more on the role of foods high in magnesium and how supplements can prevent magnesium deficiency.
Magnesium poisoning
Rarely, people experience magnesium poisoning, or toxicity, which is when they have too much magnesium. Symptoms of magnesium toxicity include vomiting, diarrhoea and abdominal (stomach) cramps. In extreme cases, too much magnesium can cause an irregular heartbeat and cardiac arrest (when the heart stops beating).
Magnesium toxicity usually only happens if you take large quantities of magnesium in the form of magnesium supplements, antacids or laxatives. You can reduce the chance of this happening by taking medicines exactly as directed by your doctor or pharmacist.
How is magnesium deficiency prevented?
To prevent magnesium deficiency, eat a healthy, balanced diet containing magnesium-rich foods. These include:
leafy green vegetables
legumes
nuts and seeds
whole grains
What are the complications of magnesium deficiency?
Health problems linked to magnesium deficiency are rare. If your magnesium levels are low for a long period of time, you may be at greater risk. This could be because of health conditions such as alcoholism or because you are taking certain medicines.
In the short-term, severe magnesium deficiency can lead to:
Health problems linked to magnesium deficiency are rare, but they can occur if you have low levels of magnesium in your body for a long time. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms.
Refining or processing of food may deplete magnesium content by nearly 85%. Furthermore, cooking, especially boiling of magnesium-rich foods, will result in significant loss of magnesium. The processing and cooking of food may therefore explain the apparently high prevalence of low magnesium intake in many populations.
In general rich sources of magnesium are greens, nuts, seeds, dry beans, whole grains, wheat germ, wheat and oat bran. The recommended dietary allowance for magnesium for adult men is 400-420 mg per day. The dietary allowance for adult women is 310-320 mg per day.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
Fruit juices such as orange juice, cherry juice, and watermelon juice are all good sources of magnesium, potassium, and phosphorus. According to the FNDDS, the average school container (124 grams) of 100% orange juice provides : 13.6 mg of magnesium.
Doses less than 350 mg daily are safe for most adults. In some people, magnesium might cause stomach upset, nausea, vomiting, diarrhea, and other side effects. When taken in very large amounts (greater than 350 mg daily), magnesium is POSSIBLY UNSAFE.
Coffee does not directly affect magnesium in your body. But it halts the further absorption of magnesium gradually in your intestines. The more coffee you consume, the less your magnesium absorption rate gets. But a heavy dose of coffee can lead to magnesium depletion.
Your brain, heart and muscles rely heavily on magnesium to do their job. Magnesium has a direct effect on the balance of other electrolytes, including sodium, calcium and potassium.
Foods that hinder magnesium absorption include: Non-fermentable or insoluble fiber, such as whole grain, bran and seeds. Foods high in phytates, such as whole flours and grains, bran, the hulls of seeds and nuts, and un-sprouted beans and soy.
Yes, studies show magnesium supplementation can help reduce belly fat storage. Magnesium modulates cortisol and metabolic pathways involved in fat distribution. Taking 200-400 mg/day of magnesium citrate as part of a healthy diet and exercise regimen may help target a reduction in abdominal fat.
Aside from medical conditions and medications that may cause it, your chances of having a magnesium deficiency go up if you have a stay in the hospital, have an alcohol use disorder, or your diabetes isn't well-controlled. Not having enough magnesium in your body can cause: Tremors. Muscle spasms.
Common magnesium-rich fruits include bananas, cherries, peaches, apricots, and blackberries. Magnesium deficiency can lead to health issues like fatigue, muscle cramps, and heart problems. Other magnesium-rich food sources include nuts, seeds, green leafy vegetables, whole grains, legumes, and seafood.
Although this does not necessarily mean low magnesium is a direct cause of weight gain, the strong correlation between increased magnesium levels and weight loss is also worth considering. Other signs of magnesium deficiency include muscle twitches, fatigue, asthma, high blood pressure, and an irregular heartbeat.
Symptoms of magnesium toxicity, which usually develop after serum concentrations exceed 1.74–2.61 mmol/L, can include hypotension, nausea, vomiting, facial flushing, retention of urine, ileus, depression, and lethargy before progressing to muscle weakness, difficulty breathing, extreme hypotension, irregular heartbeat, ...
Good advice includes reducing alcohol, coffee, sugar, dairy, and processed foods in your diet. You should also try to increase your consumption of fruits and vegetables, and consider taking a magnesium supplement.
Don't use calcium, zinc, or magnesium supplements at the same time. Also, these three minerals are easier on your tummy when you take them with food, so if your doctor recommends them, have them at different meals or snacks.
It's also claimed that magnesium supplementation increases vitamin D levels in people who are deficient in the vitamin, but causes a reduction in people whose intake is high. Too much vitamin D can increase calcium levels, which in turn can lead to certain health complications.
The benefits of magnesium supplementation in healthy individuals aren't clear, but Dr. Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.
Coffee isn't a great source of vitamins and minerals, but as a plant-based drink, it contains some, and a few that we should be getting more of. Let's start with magnesium. A cup of coffee contains about 7 mg, which is a drop in the daily-requirement bucket (420 mg for men, 320 mg for women).
Their inadequacy leads to absorption impairment, increased bleeding tendency, bone resorption, looseness, and premature tooth loss. Inadequacy of those essential minerals is associated with delayed tooth eruption and with enamel or dentin hypoplasia.
A blood test will be ordered to check your magnesium level. Normal range is 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L). Other blood and urine tests that may be done include: Calcium blood test.
