Finding a protein powder that aligns with a halal diet can be confusing. While whey protein comes from milk (which is halal), the enzymes used during the cheese-making process (rennet) often come from animal sources, which may not be halal.

In this guide, we review the best halal-certified and halal-friendly protein powders available in the UK, from clear whey to vegan options.

1. Myprotein Impact Whey Protein

Myprotein is one of the few major UK brands that explicitly labels which of their flavours are halal-certified. They use microbial rennet (plant-based) rather than animal rennet for many of their whey products.

What makes a protein powder non-halal?

There are three main red flags to look out for when checking if a protein powder is halal:

  1. Rennet: Used to separate milk into curds and whey. If the rennet is from a non-halal slaughtered animal, the whey becomes non-halal.
  2. Gelatine: Sometimes added as a thickener or in clear protein formulations.
  3. Flavourings: Vanilla extract can sometimes contain alcohol, and some artificial colourings (like Carmine/E120) are derived from insects.

Vegan Protein: The Safest Bet?

If you want to be 100% sure without checking every label, vegan protein powders are an excellent choice. Since they are entirely plant-based (pea, soy, hemp, or brown rice protein), they naturally avoid issues with animal rennet or gelatine.

Disclaimer: Product formulations change frequently. We advise checking the packaging for the official halal certification logo or a 'suitable for vegetarians' label that confirms the absence of animal rennet.
