Vitamin B12 is essential for blood formation, nerves, and cell division. Because it is found almost exclusively in animal foods, vegans and strict vegetarians are the main risk group for a deficiency.
Why Vitamin B12 is so important
B12 is involved in the formation of red blood cells and the function of the nervous system. A deficiency develops slowly because the body stores reserves – symptoms often appear only after years. More on this on our page Vitamin B12: Energy for Body and Mind.
Symptoms of B12 Deficiency
- Fatigue and Pallor
- Tingling or Numbness in Hands and Feet
- Concentration and Memory Problems
- Anemia (Anemia)
- Burning Tongue
Risk Groups
In addition to vegans, older people, individuals with gastrointestinal diseases, and users of certain stomach acid blockers are at risk. The German Nutrition Society recommends targeted B12 supplementation for a vegan diet.
Compensating for Deficiency
Those who consume animal products usually meet their needs through food. For a vegan diet, supplements or fortified foods are necessary. The appropriate dosage ideally depends on the measured value.
