Hi All. Hope i don't go on to much. For a number of years i have had a lot of the symptoms that are connected with a vit b12 deficiency .After reading all the forums I finally asked my GP for a blood test. I rang today and spoke to him and asked what my levels were, her said the are in normal range of 230? I then went on explaining how exhausted , brain foggy, aches pains etc.. plus i have been on antidepressants for many years for these symptoms may i add! I practically begged him for a therapeutic dose to see if i would feel any better, but his reply was a very firm NO, as it is line with the NHS guidelines . However he did say that if i felt that strongly i could have them done privately within the practice, but it won't make any difference .. frustrated!!
