Is Whey Protein Gluten Free?

If you’ve got a gluten allergy, then you probably realised pretty early on that it can be in quite a few unsuspecting foods. So, is it in your beloved protein shake?

The answer’s no, whey protein isn't made with gluten containing ingredients. Although gluten is a protein, it’s quite different to the one found in your shake. Gluten is found in cereal grains, particularly wheat and is responsible for giving dough its shape during the baking process. Sources of gluten include wheat, barley, rye and oats.

However, you need to pay attention to the ingredients as a lot of different whey protein powders will contain additional ingredients, including flavourings that may contain gluten (e.g. wheat).

You also want to think about the risk of cross-contamination, as some products will be manufactured in a facility that handles other gluten-containing products.

What is whey protein?

Whey protein is one of the by-products in the cheese making process.¹ It’s commonly used as a dietary supplement that can help with muscle growth and repair.² It can be purchased in different forms including protein bars and shakes.

Gluten-free proteins

The majority of people who need to exclude gluten from their diet are individuals with an autoimmune condition called Coeliac disease. Gluten intolerance/sensitivity does exist but data suggests approximately 0.5-0.6% of the global population to have this.³

Gluten-free protein includes whey concentrate, whey isolate, or hydrolysed whey. All of these are gluten-free and safe for people avoiding gluten to consume. Nevertheless, not all whey protein powders are gluten-free. Some have additional ingredients including flavourings that can be derived from allergens including gluten.

Some products are also manufactured in a facility that also handles other gluten-containing products. And some are made with no gluten containing ingredients. If a product is naturally gluten-free, it’s still important to check if it has been tested to be below the (<20ppm) threshold, so it’s a certified gluten-free product as cross-contamination is still a risk.

Take home message

For the majority of people excluding gluten from their diet, reading labels will be of second nature to you. Making sure that you are able to read ingredients lists to confirm any possible gluten-containing ingredients is essential.

If you do have a serious condition like Coeliac disease, do opt for products only containing ‘gluten-free’ stamp as these have been certified.
