Magnesium: The Power Mineral for Muscles, Nerves & Energy

You’ve likely heard of magnesium before, right? It’s one of the most well-known and essential minerals for our bodies. Hardly any other vital nutrient is involved in so many different processes – from the function of your muscles and nerves to energy production and the strength of your bones.

But what exactly makes magnesium so indispensable? How does it work in detail, and how can you ensure you’re always well-supplied? In this comprehensive guide, we take a close look at magnesium. You’ll learn all about its central roles in your body, the potential health benefits it offers, which foods are rich in it, and what you should look for when considering supplementation.

What exactly is magnesium?

Magnesium (Mg) is an essential mineral, which means that your body cannot produce it itself and is dependent on external sources. Chemically, it belongs to the alkaline earth metals. Magnesium is the fourth most abundant mineral in the human body (after calcium, potassium, and sodium). About 50-60% of the total magnesium in the body is stored in the bones, with the rest mainly found in the cells of muscles and soft tissue, and only a small amount circulating in the blood. This distribution alone shows how important it is for basic cell functions.

The Role of Magnesium in the Body: Why is it Important?

The significance of magnesium can hardly be overstated. It is a true all-rounder and acts as a so-called co-factor in over 300 enzymatic reactions. This means that many enzymes in our body simply cannot do their jobs properly without magnesium. Its most important tasks include:

Energy Metabolism: Magnesium is crucial for the production and utilization of ATP (adenosine triphosphate), the universal energy carrier of our cells. No magnesium, no energy! (EFSA Claim: Magnesium contributes to a normal energy-yielding metabolism).
Muscle Function: It plays a key role in muscle contraction and relaxation. While calcium is important for tension (contraction), magnesium ensures the necessary relaxation. (EFSA Claim: Magnesium contributes to normal muscle function).
Nervous System: Magnesium is essential for the normal functioning of the nervous system, including the transmission of nerve impulses. (EFSA Claim: Magnesium contributes to normal functioning of the nervous system).
Psychological Function: It contributes to normal psychological function. (EFSA Claim: Magnesium contributes to normal psychological function).
Protein Synthesis: Magnesium is required for the building of proteins in the body. (EFSA Claim: Magnesium contributes to normal protein synthesis).
Bones and Teeth: A large portion of the body’s magnesium is stored in the bones and contributes to the maintenance of normal bones and teeth. (EFSA Claim: Magnesium contributes to the maintenance of normal bones and teeth).
Electrolyte Balance: It helps maintain the balance of electrolytes (such as potassium and sodium) in the body. (EFSA Claim: Magnesium contributes to electrolyte balance).
Cell Division: Magnesium has a role in the process of cell division.
Reduction of Tiredness: It can help reduce tiredness and fatigue. (EFSA Claim: Magnesium contributes to a reduction of tiredness and fatigue).

How Magnesium Can Support Your Health

Due to its diverse roles, an adequate magnesium supply can positively support various aspects of your health:

Support for Muscles & Nerves: Since magnesium is essential for normal muscle relaxation and nerve function, a good supply ensures your muscles work smoothly and your nervous system fulfills its tasks. This is especially relevant after physical exertion or during phases of increased strain.
Energy & Fighting Fatigue: By supporting a normal energy-yielding metabolism, magnesium helps your body efficiently use energy from food. At the same time, it contributes to the reduction of tiredness and fatigue – a key factor for your daily well-being and performance.
Role in Psychological Well-being: Normal psychological function is closely linked to a balanced nervous system. Magnesium supports both, contributing to inner balance and stress resilience.
Importance for Bones & Teeth: Along with calcium and Vitamin D, magnesium is a vital building block for maintaining stable bones and healthy teeth. Adequate intake is therefore important throughout all stages of life.
Electrolyte Balance: The body loses electrolytes especially during heavy sweating (e.g., during sports or on hot days). Magnesium helps maintain the crucial balance of these minerals, which is important for many bodily functions, including muscle and nerve function.

Natural Sources: Where Can You Find Magnesium in Food?

Fortunately, magnesium is found in many foods. Particularly good sources include:

Leafy Greens: Spinach, chard, kale (magnesium is a component of chlorophyll).
Nuts and Seeds: Pumpkin seeds, sunflower seeds, almonds, cashews, flaxseeds, chia seeds.
Whole Grains: Oats, whole-grain bread, brown rice, quinoa.
Legumes: Beans, lentils, chickpeas, peas.
Others: Bananas, avocados, dark chocolate (with high cocoa content), certain mineral waters.

Tip: A varied diet rich in vegetables, whole grains, nuts, and seeds is the best foundation for a good magnesium supply. Keep in mind that food processing (e.g., milling grain into white flour) can significantly reduce magnesium content.

Magnesium Deficiency: Signs and At-Risk Groups

A clinical magnesium deficiency is relatively rare in healthy individuals with a balanced diet in industrialized countries. However, suboptimal supply is much more common and is not always recognized immediately. Possible, yet non-specific signs that could indicate an inadequate supply include muscle cramps (especially calf cramps), muscle twitches (e.g., in the eyelid), general fatigue, irritability, or headaches.

Certain groups have a higher risk of inadequate supply or an increased requirement:

The Elderly: Often due to lower dietary intake and changes in intestinal absorption.
People with Gastrointestinal Disorders: Chronic conditions like Crohn's disease or celiac disease can impair absorption.
Individuals with Type 2 Diabetes: Increased excretion through the kidneys.
People with High Alcohol Consumption: Alcohol promotes the excretion of magnesium.
Individuals taking certain medications: E.g., some diuretics (water pills) or proton pump inhibitors (acid blockers).
Competitive Athletes: Higher requirement due to sweating and increased metabolism.

Important: The signs mentioned above are non-specific and can have many causes. If you suspect a deficiency, it is essential to consult a healthcare professional. A blood test (whole blood analysis is recommended, as serum levels can be less indicative) can provide clarity. Please avoid self-diagnosis!

When Does Magnesium Supplementation Make Sense?

Supplementing with magnesium may be considered in certain situations:

Clinically diagnosed deficiency or inadequate supply.
Low-magnesium diets over an extended period (e.g., due to highly restrictive diets).
Increased requirement (e.g., during pregnancy/breastfeeding after consulting a doctor, or during intensive sports).
Taking certain medications that affect magnesium absorption or excretion (always in consultation with your doctor!).

The golden rule: A food supplement should never replace a healthy and balanced diet; it is designed to specifically supplement it when needed.

Fifty Five Magnesium: Quality and Products

At Fifty Five, we prioritize high-quality and well-thought-out formulations. Our magnesium complex, CALM, is a prime example. It doesn't just provide a relevant daily dose of over 200 mg of elemental magnesium; it combines two exceptionally bioavailable organic forms:

Magnesium Bisglycinate (approx. 65%): In this form, magnesium is bound to the amino acid glycine. This chelated form is known for being particularly gentle on the gastrointestinal tract and is highly absorbable. It uses a "trick" by entering the cells through amino acid transporters.
Magnesium Citrate (approx. 35%): The salt of citric acid is also a highly bioavailable and well-researched form of magnesium.

This combination is designed to ensure both effective absorption and superior tolerance. Additionally, CALM contains Vitamin B6 (Pyridoxine). Vitamin B6 is involved in many metabolic processes (including the nervous system and energy metabolism), and evidence suggests it can further support the uptake of magnesium into the body's cells.

The daily dose is divided into just two capsules (approx. 100 mg elemental magnesium per capsule), which we recommend taking in the evening.

Here you can find our magnesium complex: CALM

Intake & Dosage: What You Should Keep in Mind

The German Nutrition Society (DGE) recommends a daily magnesium intake of 300 mg for women and 350 mg for men through diet. The Federal Institute for Risk Assessment (BfR) suggests not exceeding 250 mg of magnesium per day via food supplements to avoid potential side effects like diarrhea. (This value primarily refers to inorganic compounds or single high doses; tolerance is often superior with highly bioavailable organic forms, such as those used in our products.)

With just over 200 mg per daily dose, the dosage in our CALM magnesium complex sits within the optimal range for supplemental intake.

Important Note: Individuals with kidney disease should only take magnesium supplements after consulting a doctor. Likewise, if you take medication regularly, please consult your physician or pharmacist to rule out potential interactions.
