Have just read about a factory making 1000mcg oc cynocobalamin in the UK so quality can be assured.
A larger comprehensive study /reserch if funds are got. To ascertain if b12 tablets can be of any use for PA Or b12 absorbtion issues as well as dietary.
In the current climate yes this is needed for guidance for Gps.
I do hope more is found out on injections too . Why we need different frequencies or different sorts or why we need more b12 once b12 once jections started . Also for the medical world to know so many more are self injecting making' their' problem go away by under treatment of infact withdrawing treatment!!
More reserch on PA treatment and symptoms all round .
