Prebiotics are food for the good bacteria in the intestines. They feed the intestinal flora, but also the probiotics (Karstadts Superbiotika). Karstadts Prebiotika therefore ensures maximum effectiveness of both supplied and existing intestinal bacteria. This is done through the main component: the resistant potato starch.

Resistant starch

This starch was subjected to a specific treatment to convert it into “resistant starch”. This starch cannot be digested in our gastrointestinal tract and migrates undigested into the intestine, where it then serves as food for our benign bacteria. The unwanted bacteria need a different kind of food. They cannot feed on these ingredients. Once our good bacteria are fed, they can multiply and perform their work optimally. Then they produce substances such as vitamin K3, biotin, folic acid, B12 and serotonin.

Butyric acid
We humans have about ten times more intestinal bacteria than body cells. It is important that this large amount of intestinal bacteria is also well nourished. Healthy intestinal bacteria form a resistant starch substance, namely butyric acid. Butyric acid is the best source of energy for the cells covering the intestinal wall.

Karstädts Prebiotika contains the following ingredients:

  • Resistant starch is the most important component of our prebiotics. It is starch treated in a special way that has not been heated. Due to its structure, it can enter the intestine undigested, where it then serves the intestinal bacteria as optimal food.
  • Calcium hydroxymethyl butyrate is one of the building blocks of butyric acid.
  • Inulin is another food source for intestinal bacteria. The intestinal bacteria are thus offered a wide range of food.
  • Humic acid is usually found in healthy soil. We use the purest humic acid powder available. Under the influence of humic acid, an intestinal wall can fully recover. The holes close, the inflammation subsides and the intestinal wall can recover and heal. Humic acid also has the ability to kill the disease-causing bacteria and strengthen the life-friendly microbiome.
