How do I know if I have an absorption problem??

[Sarahlouise1980]

Hi,

Im trying to decide between taking the 1000mcg Jarrows sublinguals or the 50mcg cyanocobalamin tablets. I’ve been taking the Jarrows for three weeks and have come out in an itchy acne type rash.

How do I know if I have an absorption problem? I’m hypothyroid and tested negative for the intrinsic factor.

Thank you!

If you have an absorption problem then oral B12 will not fix your symptoms.

If you do not have an absorption problem then oral B12 should fix any symptoms caused by a B12 deficiency.

There is no difference in absorption between oral and sublingual B12. ncbi.nlm.nih.gov/pmc/articl...
