Why magnesium is essential for your health
Magnesium is one of the body’s most important minerals, vital for over 300 enzymatic reactions. It is key to energy metabolism, electrolyte balance, bone strength and numerous physiological processes – from muscle contraction and proper nerve signalling to maintaining stable blood sugar and healthy blood pressure.
A lack of magnesium can lead to muscle cramps, fatigue, restlessness, headaches, constipation and sleeplessness. Around 60 % of the body’s magnesium is stored in bones, the rest in muscles and soft tissue, where it helps regulate calcium, potassium and sodium ions – crucial for normal heart rhythm and muscle performance.
Modern diets low in leafy greens, seeds and legumes, combined with daily stress and sweat loss (10–15 % of stores lost daily in active people), mean deficiency is common. Regular, high-quality supplementation is therefore essential for long-term vitality, steady energy and a good night’s sleep.
Magnesium supports bone health, muscle and nervous system function.
It Contributes to electrolyte balance, normal psychological function, normal energy-yielding metabolism and the reduction of tiredness and fatigue.

FAQ
Frequently asked questions
What is Acuraflex® Magnesium Citrate 400?
How is it different from other magnesium supplements?
What are the beneficial effects of magnesium on the human body?
How many capsules should I take daily?
When is the best time to take it?
How long can magnesium supplements be taken?
Magnesium can be taken daily and even continuously over longer periods of time, as it is an essential mineral for the human body and, compared to other nutrients (such as calcium), it is more difficult to obtain in sufficient amounts from food alone.
If you do not suffer from any specific medical conditions, it can be beneficial to supplement magnesium during periods of stress, seasonal changes, summer heat, before menstruation, during pregnancy and breastfeeding, as well as throughout menopause.
Do athletes need an increased intake of magnesium?
Prolonged periods of physical activity can cause increased loss of minerals through sweating and excretion. The excretion of magnesium in urine rises after exercise due to elevated levels of lactic acid. Surface loss through sweat can be a significant factor contributing to magnesium deficiency, especially under “extreme conditions” such as high summer temperatures or interval training.
Athletes and physically active individuals are advised to consume 10–20% more magnesium than the recommended daily intake for their sex and age group. For male athletes, an intake below 260 mg/day, and for female athletes below 220 mg/day, may negatively affect sports performance.
Why does magnesium deficiency occur in the body?
In women, for example, magnesium deficiency may occur during pregnancy and menopause, in premenstrual phases, or during periods of increased stress. In athletes, low magnesium levels can result from mineral loss through sweating or prolonged muscular effort. Magnesium deficiency is also often associated with strict diets, long-term use of certain medications, and conditions that impair magnesium absorption, such as chronic diarrhea related to inflammatory bowel disease or celiac disease.
What are the signs of magnesium deficiency?
Symptoms of magnesium deficiency vary and are often non-specific. Some of the most common include fatigue, muscle cramps, weakness, constipation, and low mood or depression.
Signs that should be taken more seriously include frequent headaches accompanied by mood changes, irritability, and insomnia. Muscle cramps, tremors, or involuntary muscle contractions may also occur. Due to the close connection between magnesium and heart function, a common consequence of severe magnesium deficiency is arrhythmia.
Is Acuraflex® Magnesium Citrate 400 suitable for vegetarians and vegans?
Yes – completely plant-based and vegan-friendly.
Does it contain allergens like gluten, lactose or artificial additives?
No – it is entirely free from gluten, lactose, GMOs, colourings, flavourings and preservatives.
Can I combine it with other supplements or medication?
