Hi I have Hashimotos Thyroid disease plus symptoms of tingling,insomnia very tired involuntary twitches, very dry eyes/nose mouth, brusing bad healing, confusion forgetfull ness does anyone think these symptoms are related to B12? my serum B12 is 752 . and Endrocinologist say it is fine and wont do active B12 tst and a couple of Thyroid Uk members have suggested I should get this done.
Can anyone tell me hre else I can get Active B12 done?
Any advice appreciated
