You could try Guar gum instead of Xanthan gum. It has similar binding properties - though I have found that xanthan tends to work better - apparently guar can inhibit the yeasts action a little and xanthan is apparently better at keeping the air bubble in the dough.
Many people use guar instead of xanthan - guar is very cheap compared to xanthan.
