Discover 5 suggestions for proven magnesium supplements to provide comprehensive support for health and well-being!
Magnesium is an essential ingredient for the health of the entire body. Its deficiencies lead to many health problems and complications. Magnesium accounts for nearly 0.05 % of the human body weight and is found in 60 % in bones, 30 % in muscles, nearly 10 % in other soft tissues and 1 % in intercellular fluids.
Magnesium is an activator of nearly 300 enzyme reactions. In addition, it protects the body against depression, stress, stroke, insulin resistance, helps to stabilise glucose levels in diabetics, acts to regulate blood pressure and proper heart function. It influences the normal course of pregnancy and prevents, among other things, early deliveries. Supplementation of this element in the event of deficiencies therefore has an impact on many important bodily functions.
Effects of magnesium on the body
The average amount of magnesium in the body is approximately 25 g. The largest amounts of this element are found in muscles and bones, smaller amounts in other soft tissues. The normal blood magnesium level is 0.54 - 0.67 mmol/l (millimoles per litre).
Magnesium has many important functions in the body and participates in the transport of calcium and potassium ions thus maintaining optimal muscle contractility, heart rhythm and nerve conduction. Other important functions of magnesium in the body are:
- - maintenance of normal teeth and bone health,
- - maintenance of normal energy metabolism,
- - reduction of feelings of tiredness and fatigue,
- - maintaining normal psychological functions,
- - support of protein synthesis processes,
- - participation in the process of cell division.
Magnesium deficiency in the body
Due to the very diverse role magnesium plays in the body, its deficiencies affect the dysfunction of many organs and systems. The most characteristic symptoms of magnesium deficiency are:
- - chronic fatigue,
- - heart rhythm disturbances,
- - painful muscle cramps and weakness of muscle strength,
- - dizziness,
- - trembling and tingling of the hands,
- - reduced resistance to stress,
- - impaired memory and concentration,
- - sleep disorders,
- - migraines,
- - hypertension,
- - nervous hyperactivity.
Magnesium - where to take it from?
The recommended daily intake of magnesium for an adult is approximately 300 - 400 mg. Such amounts can prevent deficiencies of this element. However, in order to minimise the risk of developing many diseases and to maintain very good health, this amount should be doubled. In a great many people, the intake of magnesium is much lower than the recommended amounts, not even exceeding 50% of the recommended daily intake. This is most often due to a magnesium-deficient diet and the presence of factors that increase the need for magnesium, such as pregnancy and breastfeeding, intensive mental effort, sports, and exposure to stress.
The richest sources of magnesium in the daily diet are:
- - pumpkin seeds,
- - wheat bran,
- - cocoa,
- - dark chocolate,
- - almonds,
- - whole-grain cereal products,
- - pulses,
- - raw leafy vegetables.
Even if you provide your body with many valuable nutrients, you may not provide enough magnesium. It is also important to bear in mind that magnesium is quite difficult to absorb and is quickly flushed out. A diet rich in vitamin D and B6 significantly improves the absorption of magnesium.
The best way to supply magnesium to the body is by eating the right ingredients, but of course this is not always possible. In such cases, supplementation may be helpful. The best results come from taking a variety of forms of magnesium and combining them with vitamin B6. Magnesium should be supplemented continuously for at least 3-4 months to balance magnesium levels.
Magnesium supplements
Due to the fact that magnesium is an essential element for the proper functioning of the entire body, its supplementation is one of the most common. Very many people struggle with magnesium deficiencies. However, in order for its use to have the desired effect, it is extremely important to choose the form of magnesium that is most assimilable. Then it will be possible to supplement deficiencies of this component and avoid health complications resulting from its low levels in the body.
There are many magnesium preparations available on the market. They differ primarily in the chemical form of magnesium, the dose, and the content of other active ingredients. Dietary supplements may use inorganic and organic magnesium compounds. Inorganic forms include chloride, nitrate, sulphate or carbonate. Organic magnesium salts, on the other hand, are malate, lactate, citrate, hydrogen citrate, aspartate and hydroaspartate. Organic forms of magnesium are better absorbed and it is therefore recommended to choose supplements containing magnesium in organic forms.
Another important feature of a supplement that you should definitely pay attention to is the magnesium ion content of the tablet, as well as the addition of vitamin B6. This is because this vitamin facilitates the absorption of magnesium from the digestive tract and, in addition, facilitates the transport of magnesium ions into target cells and the maintenance of magnesium stores.
Magnesium supplements - for whom?
In view of the serious consequences of magnesium deficiency in the body, magnesium supplementation is recommended for anyone whose blood magnesium level is below 0.54 mol/l. (hypomagnesaemia). However, to prevent such low levels, magnesium can also be supplemented prophylactically by including it in the daily diet.
Magnesium in supplement form should be taken by people who live under stress, are tired, experience sleep problems or experience frequent muscle cramps and twitches.
The elderly, pregnant women and people with diabetes are at high risk of magnesium deficiency.
If magnesium preparations are dosed as recommended, there is no possibility of overdosing on this nutrient. Regular magnesium supplementation comprehensively strengthens the entire organism and supports the maintenance of good health.
What are the effects of taking magnesium supplements?
Taking magnesium supplements can have a number of benefits for the overall health of the body. The most common effects of supplementation with this element include:
Improving the condition of the muscular and nervous systems: Magnesium plays a key role in the conduction of nerve impulses and muscle contractions.
Support for bone health: Magnesium is important for bone health and can affect bone mineral density. It also maintains the normal condition of teeth.
Blood pressure regulation: Some studies show that magnesium can affect the regulation of blood pressure.
Improving heart function: Magnesium is also involved in heart function and may support heart health.
Diabetes control: Magnesium may affect the sensitivity of cells to insulin, which may be beneficial for people with diabetes.
Reduction of migraine symptoms: Some studies indicate that magnesium supplementation may help reduce the frequency of migraines.
Improved sleep quality: Due to magnesium's effect on regulating the nervous system, it aids muscle relaxation, which in turn may contribute to better sleep and the maintenance of deep sleep.
Stress and tension reduction: By regulating the nervous system, magnesium plays a key role in stress reduction. It acts as an NMDA (N-methyl-D-aspartate) blocker, which can affect stress control by modulating neuronal activity.
Prevention of chronic fatigue: Magnesium is involved in the synthesis of many proteins including adenosine triphosphate, which is a source of energy for cells.
It is worth noting that the effects of taking magnesium supplements may vary depending on the body's needs and health status. Supplements should be taken in moderation and it is always a good idea to consult a doctor or nutritionist before starting to take them. Excessive supplementation is not recommended and can be harmful to the body. It is also important to choose quality products and recommended brands.
Key ingredients in magnesium supplements
Magnesium supplements may contain different forms of this element, such as chelates, organic salts (e.g. magnesium citrate, magnesium glycinate) or inorganic salts (e.g. magnesium chloride, magnesium oxide). Additional ingredients also vary depending on the specific preparation and include binders, anti-caking agents or vitamins and minerals. A very important ingredient in magnesium supplements is vitamin B6, which supports its action and absorption.
- Minerals with which it is not recommended to supplement magnesium are, for example, iron. This component, for better absorption, should be taken one hour before a meal. Magnesium, on the other hand, is recommended to be taken during or immediately after a meal. In addition, magnesium negatively affects the absorption of iron. For these reasons, it is better to take magnesium with iron separately, and at a considerable time interval.
- Calcium is another example of an element that is not recommended to be supplemented with magnesium. They may reduce each other's absorption.
- It is important to consult a doctor before starting supplementation in order to choose the right form, dose and composition of a magnesium supplement.
