Dr. Dünner Vitamin B12

Vitamin B12 helps to reduce tiredness and fatigue. It cannot be produced in sufficient quantities by the body and must therefore be obtained from food. As animal-based foods are the main source of vitamin B12, a predominantly plant-based or vegan diet can lead to a vitamin B12 deficiency. Older people, pregnant and breastfeeding women and people with gastrointestinal complaints should also make sure they have a sufficient supply of vitamin B12, as they are more frequently affected by a deficiency. Vitamin B12 is involved in various metabolic processes in the body. Vitamin B12 contributes to the normal function of the nervous system and the immune system, helps to reduce tiredness and fatigue and supports the normal formation of red blood cells.
