What are the various brands available for vitamin B12?

I have read that Neurobion is banned in India. I am suffering from Vitamin B 12 deficiency (Anaemia). I am taking this injection once a month. Please recommend a reputed brand for this injection.

 

Injectable vitamin B12 preparations are: Aristoneurol (Astra), Bethadoxin-12 (Biological E), Macraberin Forte (Allenburys), Neurotrat (German remedies) etc. Please take these drugs only under the guidance of your treating doctor.
