B-Komplex
- High-dose combination of all eight B vitamins
- DEPOT tablets for sustained release over many hours
- Vitamin B5 contributes to normal mental performance
- Vitamins B2, B6, and B12 contribute to normal energy metabolism
For energy, nerves, and mental performance
A significant portion of the water-soluble B vitamins can only be absorbed by the body in limited amounts and cannot be stored for long. For instance, if large quantities of vitamin B1 are consumed at once, the body will excrete part of it unused.
"Vitamin B" is not only a colloquial, tongue-in-cheek term for helpful social contacts, but it also represents an entire group of vitamins.

- Vitamin B1 (Thiamine)
- Vitamin B2 (Riboflavin)
- Vitamin B3 (Niacin, Nicotinamide)
- Vitamin B5 (Pantothenic Acid)
- Vitamin B6 (Pyridoxine)
- Vitamin B7 (Biotin, Vitamin H)
- Vitamin B9 (Folic Acid, Folate, Pteroylglutamic Acid)
- Vitamin B12 (Cobalamin)
The numbering of the 8 B-vitamins is not consecutive, as some additional substances were originally classified within this complex. However, over the years, it was determined that some of these substances did not exhibit the characteristics of a vitamin, leaving a series of B-vitamins with missing numbers.
B-vitamins perform many functions in the body, particularly concerning energy metabolism, the nervous system, and mental performance.
Functions of individual B-vitamins:
Biotin (Vitamin B7), Niacin (Vitamin B3), Vitamin B1, B2, B6, and B12 contribute to normal energy metabolism and support the normal function of the nervous system.
Pantothenic Acid (Vitamin B5) plays a role in normal mental performance.
Vitamin B12 helps reduce tiredness and fatigue.
Folic Acid (Vitamin B9) contributes to normal blood formation and plays a role in cell division.
Vitamins B6, B12, and Folic Acid contribute to normal homocysteine metabolism.
Vitamin B1 supports normal heart function.
The B-COMPLEX DEPOT tablet from Doppelherz system acts like a "nutrient reservoir" due to a specially developed manufacturing process. From this "nutrient reservoir," nutrients are gradually released over hours, providing the body with a sustained supply.
Despite the differing chemical structures and functions of the 8 B-vitamins for the human body, it is vital to supply all of them in sufficient amounts. This is because the B-vitamins interlock like cogs in a machine and complement each other’s functions perfectly. As components of coenzymes, B-vitamins play a crucial role in the "energy production from food."
If any part of this delicate system is missing, essential metabolic processes such as the utilisation of fats (lipids), carbohydrates (sugars), and proteins cannot proceed as usual.

Biotin (Vitamin B7), Niacin (Vitamin B3), Vitamin B1, B2, B5, B6, and B12 support normal energy metabolism, with Vitamin B6 specifically contributing to normal protein and glycogen metabolism.
Folic Acid (Vitamin B9) aids in maintaining a normal homocysteine level. Homocysteine is an intermediate product in amino acid metabolism.
Individual B-Vitamins (B9, B6, B12) also contribute to the normal function of the immune system.
To maintain a healthy and well-functioning body, it is essential to ensure an adequate supply of the entire B-complex vitamins.
With the high-dose Doppelherz system VITAMIN B-COMPLEX with DEPOT function, you are fully supported: Just one tablet per day provides you with all the B-vitamins!
B-vitamins are water-soluble and, for the most part, cannot be stored in the body for long. Vitamin B12 is an exception, as it can be stored for extended periods. Therefore, it is essential to consume adequate amounts of B-vitamins regularly through diet. With the exception of Vitamin B12, the B-complex is found in both plant-based and animal-based foods. Vitamin B12, however, is present in significant quantities only in animal-derived foods.
