According to the following peer reviewed journal, Confirmation of Gluten-Free Status of Wheatgrass, “Codex Alimentarius (a collection of internationally adopted food standards) sets the threshold level at 20 mg/kg gluten for gluten-free foods and this threshold has been adopted by many regulatory agencies such as the European Commission and the FDA.” The barley grass and wheatgrass found in our Organic Super Green Energy Booster is classified as gluten-free due to the way the materials are processed. All products are handled in a USDA Certified Organic, FDA registered facility and our global suppliers adhere to the FDA’s Foreign Supplier Verification Program. Our sourcing facility is registered and inspected for food safety by the State of Florida Department of Agriculture and Consumer Services and adhere to Good Manufacturing Practices, (cGMPs) and the Hazard Analysis Critical Control Points (HACCP) management system.
