I have a friend who will undergo gallbladder removal. She was telling me there are supplements recommended to take after surgery, one of these is called ox bile supplement (from an ox). Is it permissible (halal) to take?
If the supplement is derived from an animal that is unlawful to eat or lawful but not slaughtered according to Islamic laws it is not permissible to consume. However, if there is no alternative to this supplement, and not taking it would pose unbearable hardship it is then permissible to consume the minimum amount that can remove hardship.
