hi I have Hashimotos and I am currently pregnant.
I had my bloods done at my first midwife appointment and my b12 came back low.
the lab must have done further testing because another test came back called Methylmalonic Acid and the level shows at 677 which is very high? - does anyone know what this means and is it normal in pregnancy?
congratulations on your pregnancy
Did you get FULL Thyroid and vitamin testing as detailed in previous post 6 months ago
Exactly what vitamin supplements are you taking

B vitamins are Goldilocks vitamins when pregnant, you don’t want to be supplementing too much or too little
High methylmalonic acid often means inadequate B12.
Methylmalonic Acid
Also Known As
MMA

It is not normal in any circumstances.
My personal take is that if it has already been determined that your B12 is low, you should have immediately been started on treatment. The question being whether that should be an injection or oral. And, also test for Intrinsic Factor antibodies (though that test often produces false negatives).
It is important to know why your B12 is low.
Maybe look here:
Hi ChloeEllen. Congrats on your pregnancy! Sometimes the Methylmalonic Acid is added to verify B12. High Methylmalonic Acid reveals a true B12 deficiency. My B12 isn't low, but is lower than optimal. I just got a bottle of sublingual B-complex drops to raise my levels.
How low was B12
They should also have tested folate and ferritin
Any obvious reason for low B12
Are you vegetarian or vegan
Or are thyroid levels not very good
What are your current TSH, Ft4 and Ft3
Mine was as high as that, it means low B12. I also had enlarged red blood cells. I have to be on B12 injections. It is not good to be that high. Mine is now just scraping in at an 8 which is top of ok range.
Hi, no it is not normal and you should be given B12 injections frequently at least until MMA comes down, then regularly. The pregnancy may add to the high MMA, but in combination with low serum B12, you are deficient and the B12 needs treating. You do not want to be breastfeeding with a B12 deficiency. Best wishes
