I’d asked the same question in coeliac network (i’ve recently moved to ibs network).
Do you see any reason why it causes loose bm? Do any of you experience the same?
Thoughts crossing my mind: Casein allergy would be more serious i reckon/casein intolerance-if there is such a thing?/dairy fat?/sugar, although it’s lactose free there’s still some sugar in it-even plain sugar can throw me off sometimes?/galactose perhaps?/something to do with my thyroid condition?...
