Will using sublingual or transdermal B12 help if someone is diagnosed with pernicious anaemia? I thought the body couldn't absorb B12 because of the lack of intrinsic factor - that's why taking B12 tablets is pointless.
My daughter has 12 weekly injections and the effects only last about 4 weeks but her GP won't increase the frequency.
Can anyone give us some advice please??
Thank you in advance.
