Hi everyone,
Is this something anybody has dealt with and may know why it's happening? I've been getting monthly injections for B12 since 2017 or so. I stopped for a few months between then and now, but still... this is what my levels have been:
July 2017: levels were 148 pmol/L
July 2017: Monthly injections started (CYANOCOBALAMIN 1000 ug/ml)
October 2017: levels were 900-ish pmol/L
October 2017: Injections stopped
September 2019: levels were 263 pmol/L
September 2019: Monthly injections started (METHYLCOBALAMIN)
December 2019: levels were 1150 pmol/L
February 2020: Injections stopped
May 2020: Feeling ill again, hematologist said to resume monthly injections for life (without testing my levels based on previous levels)
(2 monthly injections of CYANOCOBALAMIN 1000 ug/ml)
July 2020: levels were 725 pmol/L
(2 monthly injections of CYANOCOBALAMIN 1000 ug/ml)
November 2020: levels were 564 pmol/L
Why is it that my levels are DROPPING while getting monthly injections? They increased for a bit, and then started decreasing again... but I haven't stopped the monthly injections since June 2020. Can anyone shed light on this? I wondered if it was Methylcobalamin versus Cyanocobalamin, but doesn’t seem to make a difference when looking at my body’s response above.
Thanks a lot,
Anna
