so that you can quickly laugh again:

acts quickly on heartburn and protects the mucous membranes of the esophagus

Heartburn - many of us have already had their experiences with the burning sensation behind the breastbone. It is often a direct reaction of the body after a greasy or heavily spiced meal, but stress can also lead to acid-induced stomach pain.

In this case, the acid in the stomach flows back into the esophagus and causes irritation there. The result is a burning sensation called heartburn.

The ingredients in Doppelherz Sodbrennen akut + protect are already released during chewing and develop their physical effect in the stomach. Thus, the chewable tablets can be used for the treatment of gastroesophageal reflux to relieve associated symptoms such as heartburn, heartburn during pregnancy, reflux esophagitis, acid regurgitation, indigestion, nocturnal reflux symptoms, cough and inflammation of the larynx and pharynx.

Doppelherz Heartburn acute + protect - the advantages at a glance:Laughing couple with pizza

  • Fast action for heartburn and acid reflux
  • Protects the mucous membranes of the esophagus
  • Convenient chewable tablets - also ideal for on the go
  • Pleasant mint taste
  • Physical effect - no habituation effect

Physical effect:

Doppelherz Heartburn acute + protect is based on sodium alginate and carbonates. Sodium alginate (a natural polymer from brown algae), together with the carbonates, forms a protective layer that (mechanically) prevents stomach acid from rising into the esophagus. This protects the mucous membranes of the esophagus and quickly relieves discomfort.
In addition, bicarbonate helps to reduce the acidity of the stomach. Due to its special properties, the product protects the mucous membrane of the esophagus from the attack of acids with a barrier effect. This promotes regeneration and helps prevent the risk of recurrence of reflux esophagitis.

Is there a difference between heartburn and reflux?

Actually, heartburn and acid reflux are two different things.
"Reflux" is the backflow of corrosive stomach acid into the esophagus. Normally, this is prevented by a sphincter between the stomach and the esophagus. However, when the sphincter no longer fulfills its function for a variety of reasons, the gastric juice rises into the esophagus.

Once the gastric juice has reached the esophagus and irritates the mucous membranes there, we speak of "heartburn". So heartburn is basically a symptom of reflux. The pain, often described as burning, can be located behind the breastbone, but can also radiate into the throat and pharynx.
In fact, acid reflux or heartburn can significantly affect quality of life. If these problems occur more frequently, a doctor should be consulted to be on the safe side.

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.

What foods can trigger heartburn?

The causes of heartburn can be very diverse. Both our lifestyle and our diet, for example, can literally hit our stomachs with lavish and late meals and lead to heartburn.

Woman feeds man with pizzaThe following foods and beverages can stimulate acid production in the stomach:

  • Promote acid production: Coffee, black tea, sweets, as well as highly spiced foods
  • Contain a lot of acid: Citrus fruits, fruit juices or carbonated drinks
  • Fatty foods: Fried foods, high-fat meats or cold cuts, baked goods such as cream pies or croissants, rich sauces, and mayonnaise
  • Hard to digest: Legumes, onions, flatulent cabbage, but also fresh bread or yeast products can take a long time todigest

Other causes of heartburn


A very nice cause of heartburn can be pregnancy. In fact, in a large part of expectant mothers heartburn occurs during pregnancy . Often, the change in hormones during pregnancy causes the muscles to relax. This can lead to the sphincter between the esophagus and stomach also being less tense, allowing stomach acid to rise more easily.

Especially in the last trimester, heartburn often occurs during pregnancy because the growing baby in the uterus presses on the internal organs - and thus also on the stomach.

Stress and worries

Who doesn't know that stressful times or psychological burdens hit the stomach? In stressful situations, hormones are produced in the body that slow down digestion. In addition, the production of gastric acid is increased - often unnoticed. We then often eat too quickly, which in turn can promote heartburn.


Sometimes medications can also trigger heartburn. Some cause an increase in stomach acid production, while others affect the tension of muscles in the body - which can also affect the sphincter between the stomach and esophagus. In this case, please talk to your doctor or pharmacist.

Excess weight

Excess pounds can also result in heartburn, as increased pressure on the stomach makes it easier for the acidic food pulp to enter the esophagus. By the way, too tight clothes or belts can have a similar effect.
