Yes, many plant-based protein powders are gluten-free, as they are typically made from gluten-free ingredients such as peas, brown rice, soy, or hemp. However, protein powders can contain added ingredients which include gluten, or there can be cross-contamination during production. For example, some protein powders may have added barley malt or other gluten-containing ingredients, while others may have been processed on equipment that also processes gluten-containing products.
Therefore, it's important to check the ingredient list and to look for a "gluten-free" label or certification on the product, or to contact the manufacturer to confirm whether the protein powder is gluten-free or not. If you have celiac disease or a gluten intolerance, it's particularly important to choose a protein powder that has been certified gluten-free to ensure that it meets strict standards for gluten content.
