Magnesium levels in the body: why this trace element is so important for health

Magnesium is one of the key elements on which the functioning of the heart, nervous system, muscles, and even metabolism depends. According to WHO і Mayo Clinic, about 60% of the population gets less than the recommended amount of magnesium from food. Its deficiency can manifest itself in the form of cramps, chronic fatigue, increased anxiety or sleep problems.

What does magnesium level mean: how is the amount of this mineral in the body estimated?

Magnesium levels refer to the concentration of magnesium in the blood serum. However, only about 11% of the total magnesium in the body is found in the blood, the rest in the bones and muscles. Therefore, even with "normal" levels in analysis a hidden deficiency may be observed.

Magnesium is necessary for:

• stable functioning of the nervous system;

• muscle contraction, including cardiac;

• level adjustment blood glucose;

• protein and DNA synthesis;

• maintaining normal blood pressure.

Normal magnesium levels: what values are considered optimal

Small fluctuations in indicators are normal, but deviations beyond these values require consultation with a doctor.

When to take a magnesium test: main indications for testing

Your doctor may order a magnesium blood test if you experience:

• frequent cramps or muscle spasms;

• irregular heartbeat;

• fatigue, apathy, irritability;

• headache or dizziness;

• nausea for no apparent reason;

• prolonged diarrhea or vomiting.

The test is also recommended for people who take diuretics, antibiotics, or have kidney or endocrine system diseases.

How to prepare for a magnesium test: tips for an accurate result

1. Blood is donated in the morning on an empty stomach (no food for 8–12 hours).

2. You should stop taking magnesium supplements 2–3 days before the procedure.

3. Tell your doctor about all medications you are taking — some of them may affect the result.

4. It is not recommended to take the test after physical exertion or stress.

The test is performed by taking venous blood. The results are usually ready the next day.

Causes of magnesium level deviations: why it is underestimated or overestimated

Hypomagnesemia (low magnesium levels) may occur due to:

• improper nutrition or restrictive diets;

• intestinal malabsorption;

• chronic stress or emotional stress;

• alcohol or caffeine abuse;

• long-term use of diuretics or antibiotics.

Hypermagnesemia (elevated magnesium levels) occurs less frequently, most often in people with kidney disease or with excessive intake of magnesium supplements.

Symptoms of magnesium deficiency: how to recognize that the body lacks a trace element

• muscle spasms or twitching;

• insomnia, feeling anxious;

• fatigue, decreased concentration;

• headache, dizziness;

• heart failure;

• high blood pressure.

According to National Institutes of Health (NIH), long-term magnesium deficiency increases the risk of hypertension, type 2 diabetes, osteoporosis, and heart disease.

How to Increase Magnesium Levels Naturally: Products and Recommendations

Magnesium is found in a wide range of natural foods. Include in your diet:

• nuts (almonds, cashews, hazelnuts);

• pumpkin, sunflower, flax seeds;

• legumes (lentils, chickpeas, beans);

• dark green vegetables (spinach, chard, broccoli);

• whole grain products (oatmeal, buckwheat, quinoa);

• cocoa, dark chocolate.

If necessary, a doctor may prescribe magnesium preparations (citrate, lactate, glycinate), but taking them without the supervision of a specialist can be dangerous.

Magnesium Excess: What Are the Risks of Taking Too Much Supplementation?

Magnesium overdose most often occurs when taking large doses of drugs on your own. Symptoms of overdose:

• nausea, diarrhea;

• lowering blood pressure;

• drowsiness, slowed breathing;

• weakness and heart rhythm disturbances.

People with kidney failure should avoid uncontrolled intake of magnesium-containing products, as the kidneys cannot always effectively remove excess mineral.

How to maintain stable magnesium levels: prevention of deficiency

• consume foods rich in magnesium every day;

• maintain water balance;

• reduce alcohol and coffee consumption;

• reduce stress levels;

• Check your magnesium levels at least once a year.

Magnesium level — it’s not just a lab test, but an important marker of your overall health. By monitoring it, you help your body maintain energy, a stable mood, and a healthy heart.
