Can celiacs eat whey powder?

Yes, most people with celiac disease can safely consume whey powder, as long as it is pure and not contaminated with gluten. Whey is a protein derived from milk and does not contain gluten naturally. However, cross-contamination can occur during manufacturing or if gluten-containing ingredients are added to the whey powder.

When choosing whey powder, individuals with celiac disease should look for products that are certified gluten-free. This certification ensures that the product has been tested and contains less than 20 parts per million (ppm) of gluten, which is the safe threshold set by many health organizations for gluten-free products1. It is also important to read the ingredient label carefully to ensure no gluten-containing ingredients, such as wheat, barley, or rye, are included in the product.

Additionally, some whey protein powders may be labeled as 'gluten-free,' but it's crucial to ensure they are also free from cross-contamination risks. This can typically be confirmed by checking if the product is manufactured in a facility that follows strict gluten-free protocols or by looking for a third-party gluten-free certification on the packaging2.

For celiacs looking to incorporate whey protein into their diet, it is recommended to start with plain, unflavored whey protein isolates, which are less likely to contain any added ingredients that might include gluten. Always consult with a healthcare provider or a dietitian familiar with celiac disease to ensure the product is safe and suitable for your specific health needs3.
