Which Promax protein bars are gluten-free?

All Promax bars are certified gluten-free by the GFCO (Gluten Free Certifying Organization). The GFCO defines the standard for gluten-free as less than 10 ppm which is half the proposed FDA standard of 20 ppm gluten. GFCO certification requires that each ingredient has been evaluated and approved by the GFCO as gluten-free. In addition, strict standards have been set in the manufacturing facility to assure no cross-contamination. Finally, the finished product is tested as final assurance that Promax bars comply with the GFCO certification.
