I don't know. It was sheep milk, so afaik it has A2 protein only. I don't get this inflamation from cheese tho. I had a frankfurt with havarti cheese, didn't feel anything relevant. Same with pizzas.is that the casein ? ive had thyroid inflammation from using iodine or pregnenolone and certain herbs like tribulus or something. never from milk. i use A2 jersey milk and it doesnt seem to cause any issues
