There is no clear confirmation that Profull Protein Powder is gluten-free based on the available information. It may not contain gluten ingredients, but there could still be traces of gluten from added ingredients or cross-contamination during manufacturing. If you have gluten sensitivity or coeliac disease (a condition where the immune system reacts to gluten and mistakenly damages the small intestine when it is eaten), it is safest to use this product only if the label clearly states it is gluten-free or after confirming with the manufacturer.
