Groups at risk of developing Vitamin B12 deficiency
Treatment
These signs and symptoms can be avoided if vegetarians chose products which are fortified with Vitamin B12. Fortified breakfast cereals are one of the few sources of Vitamin B12 from plants and can be used as a dietary source of Vitamin B12 for strict vegetarians.
If signs and symptoms develop, then treatment can be with Vitamin B12 injections given intramuscularly into your arm or buttocks or by high doses of Vitamin B12 given orally.
