How to Choose Halal Whey Protein and Supplements

Why whey needs checking

Whey is a by-product of cheese-making, and cheese is set using rennet. If animal rennet of unknown origin (potentially non-halal) was used, the whey becomes doubtful. On top of that, protein supplements often contain extra additives that can be problematic.

What makes whey halal

• Rennet source, microbial or plant-based rennet is halal. Animal rennet is halal only from a halal-slaughtered animal. Most industrial cheese uses undisclosed rennet, which is why certification matters.
• No doubtful additives, watch for added gelatin, alcohol-based flavorings, or L-cysteine (E920) from non-halal sources.

How to choose, step by step

• Look for a halal certification logo from a recognised body (for example IFANCA, HMC, HFA, JAKIM). This is the only definitive check, it verifies the rennet and the whole supply chain.
• Scan the ingredients for gelatin, alcohol-based flavours and L-cysteine.
• Consider plant-based protein (pea, soy, rice, hemp), halal by default, a simple alternative.
• Contact the brand if the rennet source isn't stated and there's no certification.

Note: "suitable for vegetarians" on cheese refers to rennet, but this label rarely appears on protein powders, rely on halal certification instead.
