True Protein Collagen Grape 300g is mushbooh (doubtful): Hydrolysed bovine collagen (92.1%) — the manufacturer's response confirmed the doubt.
What's in doubt
Manufacturer reply
“If a particular flavour is not included on our list of Halal suitable products, it is usually because one or more of its raw materials has not been confirmed as Halal suitable by our suppliers. Until we receive that confirmation, we cannot classify the product as Halal suitable.”
Hydrolysed bovine collagen (92.1%)
Bovine collagen is animal-derived, and with this flavour off the maker's halal-suitable list its sourcing is unconfirmed.
