Magnesium for muscle function + energy metabolism

The mineral magnesium is present in almost all cells and influences many important bodily functions. Magnesium is indispensable for muscle contractions and has a key role in the transmission of stimuli between muscle and nerve cells, as well as in the area of energy metabolism.

Magnesium is a vital mineral that the body cannot produce itself and can only store to a limited extent. Increased physical stress puts strain on muscles, energy metabolism and nerves. This can increase the need for magnesium.

  • Magnesium contributes to normal energy metabolism and normal functioning of muscles and nervous system.
  • Vitamin B12 contributes to the reduction of tiredness and fatigue.
  • Vitamin C and vitamin E contribute to protecting cells from oxidative stress.
  • Vitamin C additionally supports the normal function of the immune system.
  • Suitable for vegetarians + vegans
  • Lactose-free + gluten-free

Doppelherz tablets contain 400 mg magnesium in combination with 5 µg vitamin B12 as well as 120 mg vitamin C and 36 mg α-TE vitamin E.

Who should pay special attention to their magnesium balance?

Young woman doing home workout in living roomAthletes should pay particular attention to a sufficient magnesium supply, as they sweat out the important mineral on the one hand, and need it for muscle function on the other.
A small rule of thumb for athletes: during exertion lasting longer than half an hour, a small glass of low-carbonated mineral water should be drunk every 15 to 20 minutes. In addition, attention should be paid to a magnesium-rich diet with, for example, whole grain products, nuts or legumes. Dietary supplements can also help to cover the daily requirement.

Stress-ridden working people or mothers can also make good use of additional magnesium.
People over 60: In fact, our body no longer utilizes magnesium as effectively as it does in younger years - while the requirement remains the same.
Pregnant women should also pay attention to their magnesium balance, as they have to provide for the unborn child and its growing magnesium needs.

Whether during sports, when the muscles are under particular strain or under stress: in many areas, meeting the additional magnesium requirement can be an important prerequisite for an active life.

What is the V(eggie) label?

Would you like to eat a meat-free diet, consume only purely plant-based foods, or avoid certain animal ingredients for health reasons? Then keep an eye out for the V-label: it tells you whether a product meets your wishes or a restaurant offers suitable dishes.

Categories simplify orientation

The label awarded by the European Vegetarian Union (EVU) provides orientation when choosing food - as well as when buying food supplements. Thanks to the seal of approval, you can recognize vegetarian and vegan offerings at first glance when shopping and visiting restaurants.

There are 4 categories in total:

  • ovo-lacto-vegetarian (with milk and eggs)
  • ovo-vegetarian (with eggs, without milk)
  • lacto-vegetarian (with milk, without eggs)
  • vegan (completely without animal ingredients)

The food supplement Doppelherz Magnesium 400 + B12 + C + E has been awarded the vegan V-label.

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.
