Hi Laura,

Have your brother stop eating rice immediately.


You might consider a phone call with me.  This topic is far too broad to discuss in forum format.  That being said, I would encourage you to have B12 injections every two weeks for 6 months.  It is possible that your GI tract is damaged to a great enough extent that absorbing this vitamin from food may be challenging. 

Remember to also be patient.  Nerve damage typically takes the longest to heal.

All the best,

Dr. O
