Symptoms of magnesium deficiency

Symptoms of magnesium deficiency

A mild magnesium deficiency often causes no clear symptoms. However, with a more severe deficiency, you may experience various symptoms, such as:

  • Persistent headaches
  • Irregular heartbeat
  • Nausea
  • Muscle twitching or stiff muscles
  • Tingling or numbness in the arms or legs

If you recognise one or more of these symptoms, it may be useful to have your magnesium level checked.

Risks of excess magnesium

A high magnesium level in the blood is called hypermagnesemia. In mild cases, you may notice few or no symptoms, but with a more severe excess, the following symptoms can occur:

  • Persistent headaches
  • Lack of energy or drowsiness
  • Nausea and vomiting
  • Flushed face
  • Palpitations
  • Low blood pressure (hypotension)
  • Reduced muscle strength

In extreme cases, severe magnesium excess can lead to breathing problems or even cardiac arrest. It is therefore important not to take magnesium supplements without due consideration. Always consult a doctor first, especially if you are also taking medications that contain magnesium.

Biomarker summary

The importance of magnesium

Magnesium is an essential mineral that plays a key role in various processes in your body. Among other things, it supports the functioning of your muscles and nerves, helps regulate blood pressure and is important for bone formation and DNA production. Magnesium also contributes to normal muscle performance and plays a role in muscle relaxation and recovery after exercise.

The effects of magnesium deficiency

A magnesium deficiency can cause various symptoms, such as:

  • Fatigue or drowsiness
  • Muscle twitching or muscle cramps
  • Weakened bones
  • An increased risk of irregular heartbeat or palpitations

You may need more magnesium if you have an active lifestyle or exercise intensively.
A simple test can help determine whether you are getting enough magnesium through your diet or whether taking a supplement may be appropriate.

Lab results

Interpretation of your laboratory results

Understanding medical test results can sometimes be confusing. That is why it is important to know exactly what your results mean and what you can do if necessary. Test results provide a snapshot in time and can be influenced by factors such as diet, lifestyle, medication and the time of sample collection. Abnormal values do not automatically mean that you have a medical condition.

What is a healthy magnesium level?

A magnesium level between 0.66 mmol/L and 1.07 mmol/L is considered normal. Within this range, your body generally functions optimally.

Magnesium deficiency: causes and solutions

A magnesium deficiency can have various causes, such as:

  • Insufficient dietary intake
  • Poor absorption in the intestines
  • Increased loss through urine or sweat (for example due to stress or intense exercise)
  • Certain medications or medical conditions

If your test results show that your magnesium level is low, it is advisable to contact your doctor.

Some people can improve their magnesium levels by adjusting their diet, while others may benefit from supplements. In some cases, there may be an underlying cause that requires further medical attention.

Foods rich in magnesium include:

  • Almonds
  • Peanuts
  • Spinach
  • Dark chocolate
  • Quinoa
  • Pumpkin seeds
  • Chia seeds

Regularly eating these foods can help support your magnesium levels naturally.

High magnesium levels

High magnesium levels are uncommon because healthy kidneys usually excrete excess magnesium. However, elevated levels can occur due to:

  • Kidney failure
  • Addison’s disease
  • Hypothyroidism (underactive thyroid)
  • Excessive use of magnesium supplements
  • Frequent use of laxatives or antacids containing magnesium

If your magnesium level is too high, contact your doctor promptly. You may need to temporarily stop taking supplements or other magnesium-containing products, but always do so in consultation with a doctor.

Frequently Asked Questions Everything about Magnesium test

There are several types of magnesium supplements, each with their own characteristics and absorption in the body. Which type suits you best depends on your symptoms and health situation.

Common forms of magnesium:

  • Magnesium citrate: Well absorbed by the body. Helps with a magnesium deficiency and may have a mild laxative effect at higher doses.
  • Magnesium oxide: Less well absorbed, but contains a high amount of magnesium. It is mainly used for constipation.
  • Magnesium glycinate: Well absorbed and gentle on the stomach. Suitable for a deficiency without a laxative effect.
  • Magnesium malate: Well absorbed and usually does not cause digestive complaints.
  • Magnesium threonate: Well absorbed in the brain. May have potential benefits for memory and concentration.
  • Magnesium taurate: Combines magnesium with taurine. May be beneficial for blood pressure and blood sugar regulation.

Please note: Too much magnesium, especially from supplements, can cause diarrhea or other side effects. Always consult a doctor before choosing a supplement.**

EHaving too much magnesium in your body (hypermagnesemia) is rare, but it can occur in people with kidney problems or when using high amounts of magnesium supplements, laxatives, or antacids containing magnesium.

With a mild increase, you often do not notice any symptoms. However, higher levels may cause symptoms such as:

  • Abdominal pain or nausea
  • A warm feeling in the face
  • Dizziness and fatigue
  • Low blood pressure
  • Irregular heartbeat
  • Muscle weakness

In severe cases, it can lead to breathing problems or heart failure. It is therefore important to maintain a healthy balance and always consult your doctor before starting magnesium supplements or medications containing magnesium.

Most people get enough magnesium from a healthy and varied diet. Good sources include kale, sunflower seeds, cashew nuts, lentils, buckwheat, and dark chocolate.

You can improve your magnesium levels through your diet and, if needed, with supplements.

Diet

Eat magnesium-rich foods regularly, such as whole grains, nuts, seeds, legumes, and green vegetables.

Supplements

If you have a deficiency, a supplement may help. There are different types available, such as magnesium citrate and magnesium glycinate. Each type is absorbed by the body in a slightly different way. High doses may cause side effects, so always consult your doctor or pharmacist before taking supplements.

Yes, especially through supplements or laxatives containing high doses of magnesium. This condition is called hypermagnesemia. It is rare because your kidneys normally remove excess magnesium through your urine. However, in people with kidney problems, the body may not be able to eliminate magnesium effectively, which can lead to symptoms. It is very unlikely to get too much magnesium from food alone. If you are considering taking magnesium supplements, consult your doctor or pharmacist first to determine a safe dose that is suitable for your situation.
