I have posted before . I had feet and hands dumbness p, pins and needles for months, years probably. Although my first B12 was 422? I without checking paper work , I was advised to top up by thyroid UK. Had TT last year.
Also had burning mouth and tongue which used to drive me mad😡
Used B12 plus b complex and, wow, lost those awful symptoms. Last blood test put me at 1250mcg so was advised to maybe ease back, take 4 or 5 times a week.
I had used 5000mcg til about late November when I continued on 1000mcg.
Anyway within 2 days I had hints of a hot mouth and slight pins and needles with some cramping in toes, that was a thing of the past also.
I had Sub total colectomy 15 yrs ago and then right hemicolectomy 10 yrs ago.
Question is , I think , would this account for my high need to supplement ??
I understand overdoses isn't a problem? Obviously my course of action is to continue and keep symptoms at bay. Just wondered about any comments from this wise forum
Thank you
