Double Heart Banner Immune System

2-capsule system with immune-active nutrients for day + night

A sufficient supply of nutrients plays an important role for the body's own defences. Restful sleep, during which the body can relax and regenerate, is the prerequisite for a good day.

The dietary supplement Double Heart Defense Duo Day + Night contains two different capsules with vitamins (C, B6, D) and trace elements (zinc, selenium) to support a normal function of the immune system during day + night.

Double Heart Good Mood Breakfast

The capsule for the day is intended to be taken in the morning.

  • Vitamin C and vitamin D as well as zinc and selenium support the normal function of the immune system.
  • Vitamin B12 helps reduce fatigue and tiredness.
  • Caffeine helps to increase alertness and concentration.
  • Vitamin B2 helps to maintain normal mucous membranes and normal energy metabolism.

Capsule for the night:

The capsule for the night is intended to be taken in the evening.

  • Vitamin C + zinc + B6 contribute to the normal functioning of the immune system.
  • Vitamin B6 contributes to the regulation of hormonal activity.
  • Magnesium supports normal nervous system and muscle function.
  • The capsules also contain lemon balm leaf extract.

Double heart immune system

The daily dosage (2 capsules) of Double Heart Defense Duo Day + Night provides the following immune-active micronutrients: 400 mg vitamin
C + 10 mg zinc + 1000 I.U. vitamin D3 + 55 µg selenium + 25 µg vitamin B12 to support normal immune system function. Other ingredients are caffeine, magnesium, lemon balm leaf extract and vitamins B2 and B6.

Restful sleep is important for the immune system

It is a well-known wisdom that good sleep is important for our well-being. When we feel groggy, the desire for sleep is triggered by our immune system. invading pathogens alert our immune system and send our brain the signal to need sleep.

But why is sleep at night so important for the immune system?
In fact, our body's defence system can only produce so-called immune-active cells during sleep - and this is related to our hormones adrenaline, noradrenaline and prostaglandin.
These hormones keep the body from activating an immune response when awake, but during sleep the level of these hormones drops, leaving the immune cells time to work in peace.

At night, during deep sleep, the deepest sleep state is reached and physical recovery is at full speed, so deep sleep is particularly important for the regeneration of the immune system.

A regular supply of vitamins and minerals can help to support natural beauty from within.
Skin and connective tissue significantly influence our appearance and are a sign of good looks and attractiveness. With increasing age our skin tends to become thinner. This happens when the collagen content of the skin decreases and the skin elasticity decreases.

In recent years, the product range has been steadily expanded to include innovative products, including the development of a wide range of vitamin and mineral preparations, which are characterized by ever new and intelligent compositions. Every day, customers opt for the company's quality products and make Doppelherz products one of the best-selling nutritional supplements in Germany.

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.

Why Schafi-Shop and Doppelherz fit together so perfectly

The sheeps have been striving for years to use resources as sparingly as possible through small and large efforts. Of course, manufacturers that are climate-friendly or environmentally friendly fit perfectly into our portfolio.

Schafi-Shop has been implementing the reduction of climate-damaging behaviour in many commitments for years. Here are some examples:

Alliance We Save Food and Sheep Shop Within the framework of the initiative "We save food!" we have achieved that we actively avoid the destruction of food by displaying the best-before dates both visibly for our customers on and in our warehouses. The exact data on the best-before date for each product enables us to intelligently control replenishment, launch sales campaigns before a product reaches the end of its best-before date and thus successfully avoid the disposal of food.
Energy saving at Schafi-Shop We have been able to significantly reduce the consumption of electricity by paying attention to maximum energy efficiency when renewing our servers. We have been able to reduce consumption by as much as 47% compared to the old servers. Saving electricity is at least as important as promoting "green electricity". Together with our partner Vattenfall we promote regenerative power sources (EEG promoted).
German Recycling and Sheep Shop Sustainability in packaging starts with the consistent avoidance of new packaging material. For example, we use a high proportion of material received from suppliers - this not only reduces packaging waste, for which we pay taxes in accordance with the Packaging Act via our partner Deutsche Recycling, but also allows us to use packaging more than once.
LED lighting at Schafi-Shop Over the last few years we have replaced the old tube lighting in the entire logistics hall with a highly efficient and energy-saving lighting system with LED technology. And not only there, but also in many office rooms we use the latest lighting technologies to save our resources.

What's coming in the future?

We have many projects. An intelligent packaging that can be used approx. 1000 times, without padding material inside and yet perfectly protects the contents is currently being tested as a pilot.
Machine Learning to optimise the first delivery of parcels so that return transport or second delivery is avoided.
We at Schafi-Shop try to take all reasonable measures permanently - for the environment, for all of us. Thank you
for supporting us in this - by your purchase at Schafi-Shop!


Doppelherz is climate neutralWe are climate neutral

All products from Queisser Pharma GmbH & Co KG are climate neutral. The long-term goal is an even greater saving of packaging material and the use of sustainable materials for product packaging. With the savings achieved so far and the long-term reduction of packaging material, we are already making an active contribution to environmental and climate protection.

Carbon dioxide is emitted during the production of packaging, and we intend to further reduce the amount of this in the future. Unfortunately, it is not possible to completely avoid CO2 emissions during production. Together with our climate expert ClimatePartner, we fully compensate for this burden on the environment by promoting sustainable projects.

We are continuously working on a solution to offer more environmentally friendly packaging materials for our products.

Ingredients and sustainability

For our products, the high quality of the ingredients is the highest criterion. Various quality seals and standards confirm the purity and sustainability of the raw materials and ingredients.

Double heart ECO-Harvesting process

The PureMax* seal certifies that the sea fish oil is of high quality and sustainable. The omega-3 fatty acids are also produced with special care to ensure purity. Only fish from sustainable fisheries are used to produce the concentrate. Regular checks and assessments of the concentrates and also of the prescribed quality parameters confirm the extremely high quality of the omega-3 concentrate.

* PureMax is a brand of Croda International PLC, England

ECO-Harvesting process
ECO-Harvesting® Technology** effectively prevents larger by-catches when fishing for krill using special nets. The krill is thus caught particularly gently in the Antarctic Ocean. The entire catch is immediately processed on board the vessels, resulting in a very pure krill oil. The ECO-Harvesting® process** is one of the only processes in the Antarctic that has been proven to have no negative impact on the krill population and ecosystem.

** ECO-Harvesting® is a brand of Aker BioMarine
