Everything you need to know about the product: Vitamin B12

For healthy blood and healthy nerves

Vitamin B12 is a component of important enzymes and is involved in fundamental metabolic processes in the body, primarily in the formation of red blood cells (erythrocytes). B12 also supports healthy nerve function, as it is essential for the formation of myelin, the protective membranes of nerve cells. Vitamin B12 is also able to convert the amino acid homocysteine to methionine, thereby lowering the concentration of homocysteine in the blood, which helps prevent cardiovascular diseases. Vitamin B12 can only be produced by microorganisms and is mainly found in animal foods. Because the human body can store considerable reserves in the liver, a lack of vitamin B12 in adults only leads to deficiency symptoms after months or years.

Which foods contain vitamin B12?

Significant amounts of the vitamin are found in meat (especially liver), fish and seafood, milk, cheese, and eggs. Since vitamin B12 is produced by microorganisms, it is also found in fermented foods such as sauerkraut.

The effects of a vitamin B12 deficiency

Vitamin B12 deficiency can lead to anemia, damage to the nervous system, and other serious health problems. Symptoms include fatigue, weakness, difficulty concentrating, numbness and tingling in the extremities, and memory impairment. A long-term vitamin B12 deficiency can have serious consequences and should therefore be prevented by ensuring adequate intake of the vitamin.

The use of vitamin B12

Because vitamin B12 plays a central role in the body's energy metabolism, it is absorbed by cells in greater quantities to provide the missing energy, especially when dietary energy intake is insufficient. Vitamin B12 also contributes to the body's detoxification by supporting the conversion of homocysteine to methionine, thereby breaking down toxic metabolic products.

Energy supplier and detoxifier

Vitamin B12 plays an important role in the body's energy supply. It is required for the production of ATP (adenosine triphosphate), the cell's main energy molecule. Without sufficient vitamin B12, the body may struggle to produce enough energy, which can lead to tiredness and fatigue. Vitamin B12 also supports the body in detoxifying toxins by aiding in the conversion of homocysteine to methionine, thus reducing the body's exposure to toxic metabolic products.

Tagesdosis (1 Tablette) enthält:

Vitamin B12: 30 µg

Vitamin B12 tablets

Energy supplier

Vitamin B12 is a vital vitamin that your body cannot produce itself and must obtain from food. To function optimally, every single cell in your body constantly requires small amounts of vitamin B12. By taking vitamin B12, you can prevent fatigue and lack of energy, support your immune system and energy metabolism, and prevent deficiency symptoms. If you often feel tired and exhausted, a vitamin B12 deficiency may be the cause. We offer you high-dose vitamin B12. One tablet contains 30 µg of vitamin B12.

Against fatigue and for more energy

Energy vitamin B12

Since this vitamin is found almost exclusively in animal foods such as meat, fish, milk and eggs (an exception being fermented foods such as sauerkraut), vegetarians and especially vegans are dependent on an external supply of vitamin B12.

You ask – we answer

What exactly is vitamin B12?

Vitamin B12is a water-soluble vitamin from the cobalamin group (vitamin B12 group). This biologically inactive vitamin cannot be produced by the body and must be ingested through food. It is then converted in the body into the biologically active coenzyme B12. In this form, vitamin B12 plays an important role in various metabolic processes, including the breakdown of certain fatty acids and blood formation. Vitamin B12 supports cell division, the function of the nervous system, and energy metabolism, and is an important building block of a healthy immune system.

Which foods contain a lot of vitamin B12?

Significant amounts of the vitamin are found in meat (especially liver), fish and seafood, milk, cheese, and eggs. Since vitamin B12 is produced by microorganisms, it is also present in trace amounts in fermented foods such as sauerkraut.

How much vitamin B12 does my body need?

The German Nutrition Society (DGE) provides a table showing the recommended daily intake of vitamin B12 depending on age. From the age of 13, the recommended intake of the vitamin is 4 µg per day, which corresponds to 0.004 milligrams. There is no difference between men and women. However, the requirement is increased to 4.5 µg for pregnant women and 5.5 µg for breastfeeding women. With a mixed diet, only about 50 percent of the vitamin B12 contained in food is absorbed by the body. Absorption can be even lower with age – so it is not surprising that vitamin B12 deficiency occurs particularly in older people.

Am I lacking vitamin B12?

If at least one of the following applies to you, supplementing with vitamin B12 may be beneficial for you:

• Do you eat (almost) exclusively plant-based foods?
• Are you over 60 years old?
• Do you do a lot of sport?
• Do you often feel tired and exhausted?
• Do you suffer from a lot of stress?
• Are you pregnant or breastfeeding?
• Do you suffer from poor intestinal health (disturbed intestinal flora)?
• Do you suffer from chronic inflammation of the gastric mucosa?
• Do you have Crohn’s disease?
• Do you suffer from a funicular spinal disease?
• Have you had stomach surgery?
• Do you take medication that prevents the production of stomach acid?

For vitamin B12 to even pass from the intestine into the body, it must be bound to a specific transport substance produced in the stomach, the so-called intrinsic factor. If this is only produced insufficiently, for example due to stomach diseases, it can lead to long-term vitamin B12 deficiency. It should also be noted that vitamin B12 is very sensitive to light and oxygen. Significant amounts of the vitamin are usually lost during food preparation. Milk should therefore always be stored in containers protected from light and air. If milk is boiled for two minutes, it loses up to 30% of its vitamin B12 content.

What are the effects of a vitamin B12 deficiency?

A deficiency in this vitamin is usually manifested by pale skin, chronic fatigue, listlessness, and poor concentration – the typical symptoms of anemia. Furthermore, a vitamin B12 deficiency can cause neurological symptoms. These include, for example, unsteadiness when walking, discomfort, and muscle paralysis. Symptoms such as burning tongue, tingling, or numbness sometimes indicate a vitamin B12 deficiency. Furthermore, psychological symptoms such as depression or forgetfulness can be associated with a vitamin B12 deficiency in the human body. Vitamin B12 and folic acid are closely related. If there is a vitamin B12 deficiency, the folic acid stores in the tissue remain inactive, resulting in an additional deficiency of active folic acid.

What should I keep in mind when taking vitamin B12?

There are no known adverse effects from an overdose. If the body absorbs more vitamin B12 than it needs and can store, the remainder is excreted unprocessed in the urine. If deficiency symptoms occur, you should take significantly more vitamin B12 than the recommended daily dose.
