Cracked tongue

[precious78]

Does anyone know the cause of a crack down the centre of your tongue? I read it was vitamin deficiencies but not sure which and if this is correct. Dos anyone else have this?

I think it is vit b12 but can't be sure. Could you have a blood test done to find out if your lacking in something.
Take care:yesyes:

I have the low b12 and i get the cracks down my tongue sometimes, might be worth getting checked for it.
