Vitamin B12 Injection Vitamin B12 (cobalamin) is an essential water-soluble vitamin that plays a fundamental role in neurological function, red blood cell production, and DNA synthesis
Normal Dose of B12 Injection for Adults (100-1,000 mcg) The normal dose for adults ranges from 100 mcg to 1,000 mcg
Patients who have early Leber's disease (hereditary optic nerve atrophy) have been found to suffer severe and swift optic atrophy when treated with vitamin B12
The main reason that a doctor would prescribe vitamin B12 injections is if the patient is unable to obtain enough vitamin B12 on their own, whether they have pernicious anemia or are unable to get enough of the vitamin through their diet alone
However, following a balanced, nutrient-dense meal plan can improve results and make the body more responsive to metabolic interventions
Be aware that B12 may temporarily discolour urine red or orange, which is harmless
