Well-groomed hair and nails lend charm and underline the natural beauty of every woman.

Shiny, firm hair and healthy nails are an ideal of beauty for many people. But hair is not only a sign of attractiveness, but also a mirror of health. That is why a lot of time and money is often spent on styling and care from the outside.
But enough exercise, a lot of sleep, the renunciation of alcohol and cigarettes and a balanced diet make a decisive contribution to a fresh appearance.

Naturally, over the years, nail growth will diminish and hair may become thinner and less. In order to support the beauty of hair and nails, a healthy lifestyle with regular exercise and the renunciation of alcohol and nicotine is helpful.

A varied and wholesome diet is also important for an attractive appearance. The vitamins, minerals and other substances contained in fruit and vegetables are all-rounders for beauty.

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.

Double heart hairHair and nails are working hard every day!

Hair and nails need nutrients and building blocks, which must be supplied regularly and sufficiently through food. Because they deliver top performance every day through renewal and growth. For example, a hair grows about one centimetre per month. If all the hairs were added together, this would result in hair growth of 30 metres per day.

Biotin (vitamin H) and the trace elements zinc and selenium, for example, contribute to the maintenance of normal hair. Our natural hair colour (natural hair pigmentation) is supported by copper.

field horsetail
Horsetails are among the oldest plants in the world. Already in ancient times they were appreciated by the Greeks and Arabs. Horsetail is grown as a vegetable in Asia today.

L-cysteine and L-methionine
L-cysteine and L-methionine are sulphurous amino acids. L-cysteine is mainly found in the protein keratin in hair and nails. Methionine serves the body to form cysteine.

Taurine is a substance in the body that is formed from the amino acid cysteine. Taurine itself is a building block for other amino acids. It has become known as a component of some energy drinks.

Lignans are found in cereals, pulses or vegetables as well as fruit. Linseed is particularly rich in lignans. The seeds contain 75 to 800 times more lignans than other plant sources.

Double heart system HAAR PLUS contains selected B vitamins as well as magnesium and 4 trace elements. It also contains 10 mg lignans from 40 mg linseed extract, 100 mg horsetail powder, 50 mg silica, 50 mg L-cysteine, 150 mg L-methionine and 100 mg taurine.
