<bot>: Hi, Thank you for posting your query. The normal range written in the lab report papers mention a value of 200-800 for normal vitamin B 12 level, as you have mentioned.  However, for the nervous system to function properly, it should be at least more than 450. So, your vitamin B 12 value is low, but not very low. Hence, you require treatment as advised by your neurologist. I hope it clarifies. Wishing you good health, Chat Doctor.
