Magnesium for muscle and nerve function, energy metabolism and bone maintenance - in case of increased need - only 1 x daily

Magnesium is a vital mineral that the body cannot produce itself. Storage is only possible to a limited extent

Swimmer in the seaThe mineral plays a tremendously important role in many processes that take place in our body.
Most people are aware of its influence on our muscles. In fact, magnesium has a great influence on muscle tone, which means the state of tension of a muscle. In order to ensure a balance between tension and relaxation of the muscles, it is important to pay attention to an adequate magnesium supply.

Magnesium has many functions in the human body

  • Supporting the normal function of muscles
  • Supports the normal function of the nervous system
  • Contributes to normal energy metabolism
  • Contributes to the maintenance of normal bones

Magnesium 500 2-phase tablets from Doppelherz contain 200 mg magnesium from the immediate phase and 300 mg magnesium from the depot phase.

What does the 2-phase depot system offer?

The 2-phase system from Doppelherz consists of two different tablet layers due to a specially developed manufacturing process. It works on the principle of "rapid nutrient release" and "long-term nutrient release".

The principle of immediate release phase 1 and depot phase 2

In the 2nd phase as the "depot phase", the magnesium contained is released gradually over many hours and thus made available to the body on a sustained basis through smaller "portions" distributed throughout the day. In the "immediate phase", on the other hand, the magnesium is released quickly. It is thus available to the body more quickly.

Magnesium requirements

Increased physical stress at work and in sports puts strain on muscles and nerves. This can lead to an increased need for magnesium.
Many life circumstances can additionally influence the magnesium requirement. For example, older age, stress, heavy physical strain during sports or work can lead to an increased magnesium requirement.

Magnesium requirements for sports

In fact, a sufficient supply of magnesium is doubly important for athletes, because on the one hand they sweat out the important mineral, and on the other hand they need it for normal muscle function.

In order for our muscles to do their work, the body needs energy in the form of glucose. In order to metabolize glucose from our food, our body needs enzymes - and they in turn need magnesium - to function.
In addition, during athletic activities, our bodies often operate in the anaerobic zone, or oxygen debt. In this case, the body forms lactate in the muscle cell, which reduces the load capacity and must therefore be removed as quickly as possible. And it is precisely for this removal that the body needs the mineral magnesium. This makes it clear how important an adequate supply of magnesium is for athletes.

Magnesium requirements during stress610141-Double heart mother and child reading

In fact, there is a close interplay between the body and the psyche, and stress can result in physical as well as psychological complaints.

People who are stressed have an increased basal metabolic rate and can suffer from nervous overload. Often our body then reacts to longer periods of stress, magnesium can then have a supporting function on the nervous function.
Since the body can excrete more magnesium during stressful periods, it is precisely then that care should be taken to ensure an adequate magnesium supply.

Magnesium requirements in old age

With increasing age, the body's ability and effectiveness to absorb magnesium and store it in the body's own depots decreases.
In addition, some medications, for example diuretic drugs, can increase magnesium excretion. In addition, older people in particular tend to eat an unbalanced diet and drink insufficiently, so this can also lead to an inadequate magnesium intake.

The company history of Queisser Pharma

The company Queisser Pharma can look back on more than 100 years of company history. Comprehensive knowledge about health has a long tradition here.

The history of Queisser Pharma begins in 1897 in a small pharmaceutical factory in Hamburg. The graduate pharmacist Alfred Queisser had come from Lusatia in the district of Dresden to Hamburg to make his fortune as a manufacturer. He focused on the production of health and care products such as creams, liquid soap and toothpaste. Despite difficult circumstances, Alfred Queisser managed to continuously expand the company. He owed this to his extensive talents as a businessman, scientist and imaginative advertising expert, whom he united in one person.

The second root of today's Queisser Pharma was created by the Essen pharmacist Josef Peter Hennes. In 1919, he developed the original formula of today's Doppelherz® energy tonic from herbs and other natural ingredients. The tonic was produced and successfully marketed in the eponymous company founded by him.

Both houses eventually merged into "Queisser Pharma", which has been part of HGDF Familienholding Ltd. since the end of the 1970s. & Co. KG, a long-established Flensburg family business, whose parent company was founded in 1738 in Flensburg.

Queisser Pharma today

Since 1987, Queisser Pharma has its headquarters in Flensburg in the former production areas of a Rumherstellung. In addition to other brand products from Queisser, about 1 million liters of Doppelherz energy tonic are produced, bottled, packed and shipped in line with the market.

Queisser Pharma is guided by tradition and at the same time modern - with much grown experience and specialist knowledge, modern and innovative health products are regularly created. 

Demand for health products has been increasing for many decades. Our headquarters in Flensburg has therefore been continuously adapted and expanded to meet the steadily growing popularity. Here many of our products are manufactured, packed and shipped in modern production lines. From Flensburg the products reach all over Germany and all over the world. To date, we have grown to about 300 employees. This makes Queisser Pharma one of the biggest employers in the city of Flensburg.

The future of Queisser Pharma

The market for health is constantly changing. Health is becoming more and more important for every individual as well as for the social institutions.

The self-responsibility for the health increases as well as the consciousness to be able to influence the health and their continuance actively and independently. Increasing life expectancy and the rising share of older people are setting new trends and presenting the healthcare industry with new challenges. For a company involved in health products, there are great opportunities for the future.

Health awareness and demographic change

A modern medium-sized company like Queisser Pharma must actively change in this fast-paced world. A change that is characterized by major market changes, which are caused not least by the demographic development of the population structure in all countries of the world.

Never before have so many people become so old, while at the same time remaining so young, healthy and actively involved in social life. The proportion of over-60s to 100 people between the ages of 20 and 60 will almost double by 2030. In 2050, 78 out of 100 people will be over 60 years old.

Health care and personal responsibility

Life expectancy increases from generation to generation. Even today, the sixty-year-olds can look forward to more than 20 more years of life. With age, there is an interesting trend towards active health care, prophylaxis and personal responsibility. Clearly recognizable is the endeavor to provide your body with everything necessary to achieve a strong and active old age. People know that they can not leave their health today alone to the doctors. They have to take their health into their own hands and act on their own initiative and responsibility.
