Vitamin C and vitamin D - for strengthening the immune system
For a strong immune system and a healthy immune system, an adequate supply of nutrients plays an important role. Our bodies are often unable to produce these nutrients themselves. They must therefore be ingested with food. This also applies to vitamin C.
Double heart vitamin C 1000 + vitamin D DEPOT provides 1000 mg vitamin C in combination with 800 I.E. vitamin D3 to support a normal function of the immune system.
Vitamin C also contributes to a normal functioning of the immune system during and after intense physical activity. The positive effect occurs when 200 mg of vitamin C is taken daily in addition to the recommended daily dose.
Besides its function for the immune system, vitamin C contributes to the protection of the cells against oxidative stress. In addition, the vitamin increases iron uptake and contributes to normal collagen formation for normal gum and tooth function.
An adequate supply of nutrients plays an important role for health and performance.
Vitamin D - the all-rounder for your health - contributes to normal bone maintenance and normal muscle function. It also contributes to the normal functioning of the immune system. One DEPOT tablet contains 20 μg vitamin D3. This corresponds to 800 I.E. (International Units) vitamin D3. Our body can produce vitamin D through the regular exposure of the skin to sunlight. However, this self-production is often not sufficient in our latitudes. Especially in the autumn and winter months, when the metabolism is stressed and demanded, the body produces less vitamin D.
If there is no or low production of vitamin D, an increased supply of vitamin D via the diet is required. The body cannot store certain vitamins for long. If, for example, large amounts of vitamin C are absorbed at once, the body excretes part of it unused.

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.

If, for example, large amounts of vitamin C are absorbed at once, the body excretes part of it unused. The DEPOT tablet by Doppelherz works like a "nutrient reservoir" due to a specially developed manufacturing process. The valuable nutrients are gradually released from this "nutrient store" over hours and are thus available to the body for longer. |
