What is the ruling on consuming protein powder derived from pork products, and protein powder derived from meat about which it is unknown whether it was slaughtered according to Islamic, Christian, or Jewish law?

If porcine extracts are chemically treated and transformed from their original substance into another substance, then their use is permissible. However, if they do not undergo such a transformation, they remain impure and forbidden. As for meat whose slaughter is doubtful, if it undergoes transformation, it falls under the aforementioned ruling; if it does not, the preponderant opinion is to avoid it.
