Is It Halal?
Is Whey Protein Halal?
Whey itself is a dairy by-product. The question is what happens during cheesemaking — specifically, which enzymes are used.

Whey is separated from milk during cheese production. That separation usually relies on rennet, and rennet can be microbial, plant-based, or animal-derived.
What to check
- Whether the rennet used was microbial or animal-derived
- Whether flavourings use alcohol-based carriers
- Whether the certification mark covers the batch you are buying
Manufacturers answer these questions more often than people expect. A short email is usually the fastest route to certainty.
