Hypomagnesemia: What Foods to Eat for Magnesium Deficiency?

Hypomagnesemia is a condition where a person has lower levels of magnesium in the blood. Magnesium is an electrolyte important for nerve conduction, energy production, regulating blood pressure, and immune function.Reports show that magnesium is needed for about 300 biochemical reactions in the human body. 

A deficiency of magnesium is when your blood has less than0.75 mmol/L of this electrolyte. But if a person is magnesium deficient, odds are that he’ll also be deficient in other electrolytes such as calcium and potassium. 

Hypomagnesemia occurs due to kidney problems, gut issues, or lack of magnesium in the diet. Treatment is possible with supplements and dietary changes. 

Reports show that up to 15% of people are magnesium deficient at some point in their lives. Hypomagnesemia is more common in critically ill or hospitalized patients.

How Do You Know You Are Magnesium Deficient? 

Some people with magnesium deficiency don’t experience any prominent symptoms.Studies show that hypomagnesemia mostly results in neuromuscular and heart-related symptoms.

Symptoms can vary depending on the severity of the deficiency. Symptoms for mild hypomagnesemia include: 

Severe hypomagnesemia can cause the following symptoms:

  • Seizures
  • Irregular heart rhythms

What Causes Hypomagnesemia?

The most common causes why you develop magnesium deficiency include: 

  • Magnesium Deficient Dietis a common cause of hypomagnesemia. This usually means inadequate intake of foods rich in magnesium like nuts and leafy green vegetables. 

    People who eat a lot of processed foods that typically lack magnesium end up developing this deficiency.
  • Gut Problemscan result in poor absorption of nutrients. And so, even if you eat enough magnesium-rich foods, you may end up being magnesium deficient. 

    A 2022 study shows that digestive issues likechronic diarrhea can deplete magnesium levels in the body.
  • Kidney Problemscan also result in magnesium deficiency. It’s because your kidneys regulate your electrolytes by excreting the excess amounts. 

    However, if kidneys aren’t working well due to conditions like chronic kidney disease, they lose too much magnesium through urine. This loss can lead to low magnesium levels and related symptoms.

Why Magnesium Deficiency is So Common?

Not everyone but many people are magnesium deficient because modern diets lack magnesium-rich foods.Processed foods which are common in modern-day diets - often lack magnesium. 

A2022 study shows that modern farming practices have also reduced the magnesium content in the soil, so even fruits and vegetables may have less of this mineral. 

Stress, certain medications, and health conditions can also contribute to theloss of magnesium and therefore, its deficiency.

How to Check Magnesium Deficiency?

You can check magnesium deficiency in the following ways:

  • Blood Test is the most common way to check for magnesium deficiency. The test measures the amount of magnesium in your blood. Doctors take a small sample of your blood and send it to a lab. Even though only 1% of total body magnesium is in the blood, this test can still show if levels are too low.
  • The Magnesium RBC Testlooks at the magnesium inside red blood cells. This test can provide more accurate information about long-term magnesium levels. It’s often used if a regular blood test doesn’t show a clear result.
  • Urine Tests can also help check magnesium levels. This test measures how much magnesium your body gets rid of through urine. It can show if your body is losing too much magnesium.

How to Deal with Hypomagnesemia?

Treatment option depends on the cause behind magnesium deficiency. If it is because the gut is not absorbing magnesium from the diet, the treatment focuses on improvinggut health. If the renal system or kidneys are responsible for excess loss of magnesium, treatment is focused on improving renal functioning. 

Aside from addressing the underlying cause, doctors will also recommend magnesium supplements or diet to cure hypomagnesemia. 

Some practical ways to improve magnesium deficiency are:

1. Supplements

For mild deficiency, where symptoms are not severe, doctors usually recommend getting magnesium in the diet. However, when the deficiency is severe, doctors will prescribe you magnesium supplements to normalize magnesium levels in the body. 

In some severe cases, you may also be given magnesium through IV drips to prevent serious complications. 

2. Foods To Eat For Hypomagnesemia

Dietary changes are a major component in the treatment and long-term management of magnesium deficiency. The diet should focus on getting the recommended amount of magnesium daily. 

Experts suggest that an adult man should get 400 to 420 mg of magnesium and an adult woman should get 310 to 320 mg of magnesium daily.

 Here are some foods you can eat with magnesium deficiency:

  • Leafy Green Vegetables can be your great partner in fighting against magnesium deficiency. Spinach and Swiss chard are some of the magnesium-rich leafy green vegetables to add to your diet.

    Reports show that 100 g of spinach contains 79 mg of magnesium. Similarly, 100 g of Swiss chard provides you with86 mg of magnesium
  • Incorporating nuts into your daily diet can significantly boost magnesium levels. Some nuts such as almonds and cashews are rich in magnesium and can fulfill your daily magnesium requirements.

    Reports show that 100 g of almonds provide you with 270 mg of magnesium which is more than half of your daily requirements. Similarly, 100 g of cashews contains292 mg of magnesium.
  • Seedssuch as pumpkin and chia seeds are another healthy food option for hypomagnesemia. According to reports, 100 g of pumpkin seeds provide you with262 mg of magnesium

    Chia seeds are also very rich in magnesium, containing 355 mg of magnesium per 100 g.
  • Whole Grains provide you with decent amounts of magnesium and also improve gut functioning. Replacing refined grains with whole grains willsupply many essential nutrients for your body in addition to magnesium. 

    Reports show that 100 g of whole grains such as oats contains 138 mg of magnesium. Some other examples of whole grains include brown rice, wheat, and millet. 
  • Legumesare nutrient-rich foods that provide healthy amounts of magnesium and some other nutrients such as potassium and iron. 

    Reports show that black beans which are legumes contain 70 mg of magnesium for each 100 g serving. Some other examples of legumes include lentils, peas, and chickpeas. 
  • Dark Chocolate is a very good snack to eat with magnesium deficiency. Studies show that 100 g of dark chocolate contains252 mg of magnesium. It is also a good source of iron and contains plenty ofantioxidants for overall health. 

3. Foods To Avoid For Hypomagnesemia

Eating certain foods with hypomagnesemia can worsen the deficiency. Some of these foods lack magnesium while others promote magnesium loss through urine.

Here are some foods to avoid with hypomagnesemia:  

  • Sugary Snacks like candy and pastries can lower magnesium levels in your body. High sugar intake makes yourkidneys release more urine which can result in more magnesium loss through urine.
  • Sodas or carbonated drinks are high in phosphate.Studies show that high levels of phosphate can block magnesium absorption. It's best to cut back on soft drinks to keep your magnesium levels up.
  • Chronic alcohol consumption can deplete magnesium levels by causing your body to lose more of it through frequent urination.Studies show that alcohol also impacts the absorption of magnesium from foods.
  • Processed foods such as fries, processed meat, and frozen meals often lack nutrients, including magnesium. They can make it harder to maintain healthy magnesium levels.
  • Caffeinated and energy drinksalso promote magnesium loss. Studies show that caffeinated drinks such as coffee can increase frequent urination, which may result in magnesium loss. Reducing caffeine intake may help improve your magnesium levels.

4. Home Remedies

Some home remedies that are common in practice for magnesium deficiency are:

  • Magnesium-Rich Smoothies:Blend magnesium-rich foods like spinach, bananas, and almonds into a smoothie. This makes it easy to get more magnesium in your diet. A daily smoothie with these ingredients helps boost magnesium levels and supports your overall health.
  • Magnesium Oil:Using magnesium oil on your skin is another effective home remedy. Somestudies claim that magnesium absorption through the skin is more efficient compared to the oral method.

    The oil can be sprayed directly onto the skin, allowing magnesium to absorb easily. It’s a quick way to increase magnesium levels, especially if you're having trouble absorbing it through food.
  • Epsom Salt Baths: Epsom salt baths can help boost magnesium levels. Epsom salt is rich in magnesium sulfate which can be absorbed through the skin. The working mechanism for Epsom bath suggests that a warm bath with a cup or two of Epsom salt can relax muscles and improve magnesium levels naturally.

Can I Take Fiber and Magnesium Together?

If you are taking magnesium supplements for hypomagnesemia but also want to take fiber supplements orfiber powder for gut health, you don't have to worry about taking them together. 

Fiber supplements don’t affect the absorption of magnesium in your body. Astudy in The Journal of Nutrition shows that fiber doesn’t interfere with how your body absorbs magnesium. In fact, astudy shows that taking fiber and magnesium together in your diet can reduce the risk of chronic diseases such as diabetes.

Both fiber and magnesium have their own benefits. Fibersupports digestion and helps with gut health, while magnesium is important for muscle and nerve function. So, you can safely include both in your daily routine for overall health improvement.
