In general, beef protein powder is gluten-free as it is derived from beef and gluten is a protein found in wheat, rye, and barley. However, it is important to check the ingredient label or manufacturer information to ensure that no gluten-containing ingredients have been added to the product. Some manufacturers may process their beef protein powder in a facility that also processes gluten-containing products, which could lead to cross-contamination. If you have a gluten intolerance or celiac disease, it is best to consult with your healthcare provider before using any protein powder products.
