Overview
Whey is a liquid by-product of cheese or yogurt production. It contains proteins, lactose, vitamins, and minerals. Whey protein is commonly used in sports nutrition, baked goods, and dairy products.
Sources & Production
Whey is derived from milk during the cheese-making process. While milk itself is halal, the halal status of whey depends on the rennet used to make the cheese.
Islamic Ruling
Whey is classified as Mushbooh (Doubtful) because:
- If the cheese was made with microbial or vegetable rennet, the whey is Halal
- If the cheese was made with animal rennet from a non-halal slaughtered animal, the whey is Haram
- Most commercial whey does not specify the rennet source
Conservative Advice: Unless the product carries a Halal certification or specifies vegetable/microbial rennet, it is safer to avoid.
Conclusion
Whey is Mushbooh due to uncertainty about rennet source. Look for Halal-certified whey products.
