What Is Whey?

Whey is a type of protein that comes from milk. After milk has been through the straining process, the remaining liquid is whey. It can be used to make cheese. It’s more commonly known as a protein supplement. It is great for a range of uses such as strength increase and bettering your athleticism. It’s also been proven to have positive effects on your immune system and nutrition.

Is Whey Gluten-Free?

In short – the answer is yes! Whey is naturally gluten-free. This is because the whey protein itself does not contain any form of gluten. You may see whey on packaging listed as “whey concentrate”, “whey hydrolysate” or “whey isolate”. All those variations of whey are gluten-free and are consumable on a gluten-free diet.

Does Whey Protein Have Gluten?

Whey protein is naturally gluten-free and suitable for consumption. However, whey protein powder is a different substance and one we must look at in more detail.

Is Whey Protein Powder Gluten-Free?

This is the ingredient you’ll most often see in your protein shakes and powders. It’s important to note that most whey protein powders are not usually gluten-free. They’re not usually made from just whey protein and often have many additional ingredients. Even if the packaging seems gluten-free, be sure to check the labels as protein powder can be sneaky!

Flavorings, preservatives, and thickeners are often ingredients in whey protein powder. So besides the obvious, rye, barley, and wheat, you may want to also look out for the following warning words on ingredient labels:

  • wheat protein
  • malt
  • spelt
  • bulgur
  • oats
  • modified food starch
  • artificial flavorings

Some of these may be safe, but the label will state if any of the above ingredients have derived from gluten.

Manufacturing Methods

Something to also bear in mind is manufacturing methods. While there may not be any gluten-containing ingredients, it may have come into cross-contact with such ingredients when being made. You can check this on the packaging, or if you’re still unsure – contact the company yourself. Whether it’s a phone call or an email, companies are usually more than happy to help.

Cross contact is always a risk if a product isn’t certified gluten-free, so if you’re super sensitive or live with celiac disease, it may be best opting for certified products only.
