Key element for energy, focus & vitality

Vitamin B12 (Cobalamin) is an essential, water-soluble vitamin that plays a key role in energy and vitality – both in everyday life and in the long term. It supports the normal formation of red blood cells¹⁰, which are essential for oxygen transport in the body, and contributes to the function of a healthy nervous system². This promotes mental resilience and lays the foundation for an active life. Vitamin B12 is also involved in energy metabolism⁶, which helps reduce tiredness and fatigue⁹. It also makes an important contribution to psychological function³ and the maintenance of a healthy immune system¹. Through its role in homocysteine metabolism, vitamin B12 supports cardiovascular health¹¹ and contributes to a vital and balanced life in the long term.

In the context of healthy aging and longevity, vitamin B12 is increasingly coming into focus because it plays a central role in epigenetic processes. Epigenetics describes how environmental factors and lifestyle influence gene activity without altering the DNA sequence—that is, whether genes are "switched on" or "switched off." With age, dysregulated patterns of this switching on and off become increasingly common, which is considered one of the early molecular hallmarks of aging. (López-Otín et al., 2023)

Vitamin B12 – along with other methyl group donors – is directly involved in methylation reactions that are important for one-carbon metabolism, orderly DNA methylation, and normal cell division. (Mandaviya et al., 2019; Zeisel, 2017)

DNA methylation acts like cellular switches and is closely linked to cell division and DNA integrity. By supporting these processes and contributing to normal cell division, vitamin B12 helps maintain the stability of the genome – a mechanism that is particularly important for slowing down cellular aging processes and preserving healthy cell functions in the long term.

Since vitamin B12 is found almost exclusively in animal products such as meat, fish, eggs, and dairy products, targeted supplementation can be beneficial for vegetarians and vegans. In our All in One Complex, Vitamin B12 is used in the form of bioactive methylcobalamin.
