    Could I be B12 deficient?

    Related Topics
    For 7 months now I have had the following symptoms: Tingling in arms/feet Fullness in right ear Off balance/dizziness/ light headed (this is my major concern) I've had neurological nerve tests, MRI's, CT scans of brain and auditory canal. All have came back normal. However, had my bloods done and my B12 total is 203 pmol/L Active B12 106 pmol/L. Although, GP isn't concerned, from what I have read this is very low and could be why I'm getting symptoms.

    My research interests include immunology and the mechanisms of amyloid formation. The latter has implications for people who are dealing with Alzheimer's Disease, Parkinson's Disease … View Profile

    The current cut-off for Vitamin B12 is about 400 pg/mL (about 300 pmol/L) - anything lower than that probably needs taking it as a supplement.

    It is preferable to take it as methylcobalamin on an empty stomach with no food for about an hour afterwards.

    An Accredited Practising Dietitian whose knowledge is up-to-date should be able to help you with this.
