Magnesium is a vital mineral, which is often underestimated, but plays a key role in numerous functions in our body. From regulating energy metabolism to supporting muscle function and maintaining healthy cardiovascular function, magnesium is essential for our well-being. In this article, we'll take a closer look at the importance of magnesium, explore its various functions in the body and how you can ensure you're getting enough of this important mineral.
Magnesium in general
Magnesium is an essential mineral, which plays a crucial role in many bodily functions. It is the fourth most abundant mineral in the human body and is involved in over 300 biochemical reactions.
What is magnesium?
Magnesium is a naturally occurring mineral found in many different foods, in the human body and in the earth. In the body, it is mainly stored in the bones, muscles and soft tissue and contributes to energy production, protein synthesis, muscle and nerve function, blood sugar control and blood pressure regulation.
Important functions of magnesium in the body
Magnesium not only supports muscle and nerve functions, but is also essential for energy production and the synthesis of DNA and RNA. It also contributes to the structure of bones and cells and is important for the electrolyte balance in the body.
Sources of magnesium
An adequate intake of magnesium is essential for good health, and fortunately magnesium is naturally present in many foods.
Foods with a high magnesium content
Here are some of the best natural sources of magnesium:
- Green leafy vegetables: spinach and chard are particularly rich in magnesium.
- Nuts and seeds: Almonds, sunflower seeds and pumpkin seeds are excellent sources.
- Wholemeal products: Wholemeal bread, brown rice and quinoa contain considerable amounts of magnesium.
- Pulses: lentils, black beans and chickpeas are not only rich in protein, but also good sources of magnesium.
- Chocolate: chocolate is a delicious and healthy source of magnesium.
Magnesium supplements: advantages and disadvantages
While most people can meet their daily magnesium requirements through a balanced diet, supplements may be necessary or beneficial in some cases.
Advantages
- Practical: They are a quick and easy way to increase magnesium levels.
- Controlled dosage: Supplements allow precise control of magnesium intake, which can be particularly helpful in cases of deficiency.
Disadvantages
- Possible side effects: Excessive doses can lead to gastrointestinal complaints, such as diarrhoea.

Magnesium and your health
Magnesium plays a key role in overall health. In this section you will learn how magnesium contributes to heart health, its importance in diabetes and bone health and how it supports mental health and muscle function.
Heart health
Magnesium is known to play an important role in heart health. It helps regulate blood pressure, which is a key factor in preventing heart disease. Studies show that adequate magnesium intake is associated with a lower risk of various heart diseases, including heart attacks.
Diabetes
Magnesium plays an important role in diabetes by improving insulin sensitivity and supporting normal blood sugar regulation. Low magnesium levels can often be found in people with type 2 diabetes, which can exacerbate insulin resistance.
Bone health
Magnesium is essential for bone formation and maintenance. It influences the activity of osteoblasts and osteoclasts, which are responsible for bone formation and resorption. An adequate intake of magnesium can help to reduce the risk of bone diseases such as osteoporosis.
Mental health
Magnesium also has a calming effect on the nervous system, making it a valuable mineral for coping with stress and anxiety. It is also being researched for its role in the treatment of depression and other mental illnesses.
Muscle health and cramps
Magnesium is crucial for muscle contraction and relaxation. It helps to regulate the transmission of nerve signals and thus supports normal muscle movement. A magnesium deficiency can lead to unpleasant muscle cramps, twitching and general muscle stiffness. Regular intake of magnesium can help to alleviate these symptoms and plays an important role in the prevention and treatment of muscle cramps, especially in athletes and the elderly.
Daily magnesium requirement
In order to fully utilise the numerous health benefits of magnesium, it is important that you know and meet your daily magnesium requirements.
How much magnesium do you need?
The recommended daily intake of magnesium varies according to age, gender and stage of life. Here are some general guidelines:
- Adult men: 400-420 mg per day
- Adult women: 310-320 mg per day
- Pregnant women: 350-360 mg per day
- Breastfeeding women: 310-320 mg per day
- Children and adolescents: The recommended amount varies by age and gender, with recommendations ranging from 80 mg for young children to 360 mg for older teens.
It is important to note that certain conditions or lifestyles can increase your magnesium requirements. For example, athletes often need more of this mineral due to the loss of magnesium caused by sweating.
Differences in necessity: children, adults, senior citizens
Children and adolescents need sufficient magnesium for growth and development, while adults need it to maintain physical function and prevent disease.
Seniors, on the other hand, are often at risk of developing a magnesium deficiency, partly due to changes in dietary habits and partly due to altered body absorption, which can specifically adjust their requirements.
Magnesium deficiency
A magnesium deficiency can lead to a variety of health problems. Here we discuss how you can recognise whether you may be taking in too little magnesium.
Signs and symptoms of magnesium deficiency
Symptoms of magnesium deficiency can be subtle and develop over time, but some early signs may include:
- Muscle weakness and cramps
- Mental problems such as apathy or depression
- Rapid fatigue and weakness
- High blood pressure
- Cardiac arrhythmia
Risk factors for magnesium deficiency
Certain groups of people are more susceptible to magnesium deficiency, including:
- People with diseases that impair nutrient absorption, such as coeliac disease or chronic intestinal diseases.
- People who regularly take certain medications, such as diuretics or antibiotics, which can impair magnesium absorption.
- Older people, whose nutritional status is often not optimal.
- Athletes who sweat a lot and lose magnesium as a result.
The benefits of magnesium
Magnesium is not only important for basic bodily functions, but also offers a range of benefits that can significantly improve your quality of life.
Prevention of diseases
Magnesium contributes to the prevention of a number of chronic diseases. Studies have shown that adequate magnesium intake is associated with a reduced risk of several conditions, including:
- Cardiovascular diseases: Magnesium plays a key role in heart health due to its ability to lower blood pressure and prevent cardiac arrhythmia.
- Type 2 diabetes: Magnesium improves insulin sensitivity and can help regulate blood sugar levels.
- Stroke: Some research suggests that a higher magnesium intake is associated with a reduced risk of stroke.
Performance improvement and recovery for athletes
Magnesium can be particularly beneficial for athletes. Not only does it help to produce energy and reduce oxygen requirements during exercise, it also helps to prevent muscle cramps and reduce recovery time after exercise. Magnesium can also help to increase performance and minimise the risk of injury.
