Magnesium Deficiency: 5 Warning Signs

Magnesium is an essential mineral that is crucial in maintaining your overall health. It involves various bodily functions, including regulating blood pressure, blood sugar levels, and muscle and nerve function. 

However, many people unknowingly suffer from hypomagnesemia, also known as magnesium deficiency, which can negatively impact their well-being.

In this article, we will discuss seven signs and symptoms of magnesium deficiency that you should be aware of. 

Recognizing these indicators early on can help you take the necessary steps to address the issue and ensure your body has adequate magnesium levels for optimal health and functioning.

Magnesium Deficiency Manifestations

Magnesium deficiency often goes unnoticed until it becomes severe. This essential mineral plays a crucial role in hundreds of biochemical reactions in your body and its deficiency can lead to health issues. 

Should you suspect a magnesium deficiency, it’s important to consult with a healthcare provider.

Muscle Twitches and Cramps

Muscle twitches and cramps can be painful symptoms of magnesium deficiency. When your magnesium levels deplete, it’s harder for muscles to relax, leading to spasms and cramps.

This deficiency commonly contributes to muscle weakness and fatigue. You may experience sudden, involuntary muscle contractions, which can be quite uncomfortable.

Mental Health Conditions

Deficiency in magnesium can contribute to various mental health conditions.

Anxiety is one mental health condition closely related to magnesium deficiency. Low magnesium levels can exacerbate feelings of stress and unease. Boosting magnesium intake may help alleviate some anxiety symptoms.

Depression can also be influenced by magnesium levels. Insufficient magnesium might worsen depressive symptoms while increasing magnesium intake could offer some relief.

Stress is yet another aspect of mental health that can be affected by magnesium deficiency. Remaining attentive to magnesium levels during periods of high stress can be essential for maintaining mental well-being.

It’s important to monitor your magnesium levels and intake to maintain your mental health. 


Osteoporosis is a condition where your bones become weak and brittle due to a lack of essential minerals, such as calcium and magnesium. As you age, the risk of developing osteoporosis increases, especially if you have a magnesium or vitamin D deficiency.

Magnesium plays a vital role in bone health, as it helps with the absorption and metabolism of calcium. A magnesium deficiency can lead to a decrease in bone density, making them more susceptible to fractures.

Vitamin D is also crucial in maintaining strong bones, as it aids in calcium absorption. A deficiency in vitamin D can further exacerbate the effects of a magnesium deficiency on your bone health.

Maintaining an adequate intake of magnesium and calcium, along with sufficient levels of vitamin D, is essential for maintaining strong and healthy bones and reducing the risk of osteoporosis.

Fatigue and Muscle Weakness

When you have a magnesium deficiency, fatigue and muscle weakness can often occur. Low magnesium levels can affect your body’s ability to contract and relax muscles properly.

One common symptom of magnesium deficiency is a condition called hypokalemia, which involves low levels of potassium in the blood. 

Potassium and magnesium work together to ensure healthy nerve and muscle functioning. If you experience constant fatigue and weakness, it may be an indication that your magnesium levels are low. 

High Blood Pressure

Magnesium plays a crucial role in regulating blood pressure. Hypomagnesemia can lead to high blood pressure. This is because magnesium helps to relax and dilate blood vessels, allowing for proper blood flow. 

Keep in mind that high blood pressure can also result from factors other than magnesium deficiency. Nonetheless, maintaining adequate magnesium levels is one aspect of supporting overall heart health and controlling blood pressure.


Asthma is a condition that can be affected by magnesium deficiency. 

Magnesium plays a crucial role in the function of your respiratory system by helping relax the bronchial muscles and expanding the airways. This allows more air to flow in and out of your lungs.

The benefits of magnesium for asthma come from its properties as a bronchodilator, which helps reduce constriction and inflammation in the airways.

Irregular Heartbeat

Irregular heartbeat or arrhythmias are abnormal heart rhythms that can result from low magnesium levels in your blood.

Magnesium plays a crucial role in maintaining a healthy heart. It helps in proper nerve conduction and cellular function, both of which are essential for maintaining a regular heartbeat.

When you experience a magnesium deficiency, your heart may not function as efficiently. This can lead to palpitations or the sensation of skipped heartbeats. In severe cases, magnesium deficiency can result in cardiac arrest.

Magnesium Deficiency, Age, and Gender

As you age, your body’s magnesium absorption rate decreases, making older adults more susceptible to magnesium deficiency. This lowered absorption becomes more prominent as you enter your 50s and beyond.

In addition to age, gender plays a crucial role in magnesium deficiency. Women, especially during pregnancy, require higher magnesium levels to support the developing fetus.

Moreover, women going through menopause often experience hormonal fluctuations, leading to a higher risk of developing a magnesium deficiency. It’s essential for women of all ages to monitor their magnesium intake to maintain overall health.

Magnesium Deficiency in Chronic Conditions

Certain chronic conditions can increase your risk of developing magnesium deficiency.


Low magnesium levels are common in people with type 2 diabetes. Poorly controlled diabetes increases the risk of magnesium loss in your urine.

Conversely, magnesium deficiency can worsen insulin resistance, a hallmark of type 2 diabetes.

Celiac Disease 

This autoimmune disorder impairs the absorption of nutrients, including magnesium, in your small intestine.

This can lead to a deficiency despite adequate dietary intake.

Chronic Diarrhea 

Persistent diarrhea can cause magnesium depletion, especially if you are losing large amounts of fluids.

If not replenished, it can result in a magnesium deficiency, leading to various related health issues over time.


This inflammation of the pancreas can contribute to magnesium deficiency. 

It interferes with the body’s ability to absorb nutrients, including magnesium, leading to potential deficiency.

Medication Affecting Magnesium Levels

Certain medications can impact your magnesium levels. Proton pump inhibitors (PPIs) are a common culprit, as they reduce stomach acid production and may interfere with magnesium absorption. 

If you’re taking PPIs, monitor your magnesium levels closely.

Diuretics, used to manage high blood pressure or fluid retention, can lead to increased magnesium excretion. This may result in lowered magnesium levels. Pay attention to your magnesium intake while using diuretics.

Antibiotics, particularly aminoglycosides and tetracyclines, can negatively affect magnesium levels. They can interfere with magnesium absorption in the gastrointestinal tract or increase its excretion. Consult your healthcare provider if you’re on long-term antibiotic therapy.

Alcohol and Magnesium Deficiency

Alcohol consumption can negatively impact your magnesium levels. This is particularly true for those with alcohol use disorder.

Excessive alcohol intake can cause your kidneys to excrete more magnesium in your urine. This results in a depletion of your body’s magnesium stores.

It’s essential to consume alcohol in moderation and maintain a balanced diet to avoid this issue. 

If you have concerns about your magnesium levels or alcohol consumption, consult a healthcare professional for guidance.

How to Get Enough Magnesium

To ensure adequate magnesium intake, include a variety of magnesium-rich foods in your diet. Leafy green vegetables such as spinach, nuts, seeds, beans, whole grains, potatoes, avocados, bananas, milk, salmon, and halibut are excellent sources of magnesium.

Protein-rich foods can also enhance magnesium absorption, so incorporating them into your meals may help you reach the recommended dietary allowance (RDA) or adequate intake levels.

When choosing magnesium supplements, consider the different types available: magnesium sulfate, magnesium citrate, magnesium oxide, and magnesium chloride. Each form has its own absorption rate, so consult a healthcare professional for guidance.

Remember, it is always best to prioritize food sources over supplements for obtaining magnesium. By incorporating a diverse range of magnesium-rich foods into your meals, you are well on your way to optimal health.
