Is Optimum Nutrition Protein Powder 100% Gold Standard Gluten-Free?

Optimum Nutrition is part of Glanbia, a cheese and nutritional manufacturer. It offers nutritional products in every category, including protein powders, nutrition bars and vitamin supplements, according to the Optimum Nutrition website. While many of these products are gluten-free, including most of the 100 Percent Gold Standard protein powder flavors, the manufacturing plant is not a gluten-free facility. If you require a gluten-free diet, use caution when considering the 100 Percent Gold Standard Protein powder from Optimum Nutrition.


Gluten is a protein found in wheat, barley and rye and any food products containing these ingredients. Most people can safely consume gluten without any problems. If you have a condition such as celiac disease or gluten-intolerance, however, you need to avoid foods containing gluten to prevent illness. When you consume foods containing gluten, your body will react by attacking and damaging your digestive system, causing malabsorption and malnutrition.

If you have to follow a gluten-free diet you need to avoid all foods containing wheat, barley and rye. This includes most breads, pasta, crackers and processed foods. Eating even a small amount of gluten is harmful to your digestive system and health. Reading food labels can help you identify foods you need to avoid. It is also important that you avoid foods that may have come in contact with gluten, causing cross-contamination. For example, a toaster used to toast regular wheat bread is considered contaminated with gluten, and a separate toaster should be used to toast your bread.

Because the protein powder comes in a variety of different flavors, it is important that you check the label and ingredients of each mix to determine if it contains gluten. According to Optimum Nutrition, the only flavor of the protein powder that contains gluten is Cookies and Cream, all other flavors are gluten-free. Though the other protein powders do not have any added gluten, the company cannot 100 percent guarantee that they are gluten-free because the same equipment is used to make both the gluten-free and gluten-containing products.
