So i took a B12 serum test that was (see below) , i spoke to my GP who requested their own test, which the lady on the phone just said they are normal.
i asked for a copy and i need to go pick them up but im tired of waiting, the doctors notes on the test below which i got done privately says 400-500 is adequte etc and anything lower may cause symptoms so i think im going to start my methyl b12 lozenges.
Is there anything i need to be aware of as iv herd of people getting side effects because of methyl problems and things like that? im worried to be honest, i hate taking anything new incase it reacts badly and makes me even worse
B12 166 250-725
