The National Formulary (NF) and the United States Pharmacopeia (USP) are the official references and approved manufacturing guides for drugs, dietary supplements and other products. The NF (published under the same cover with the USP) contains over 380 published standards (monographs) for dietary supplements. When a standard is published in the USP-NF, federal and state government agencies have the authority to enforce these standards to ensure that the ingredients or supplements match these stringent standards. Chromax chromium picolinate is manufactured to these standards.
When purchasing a chromium picolinate supplement, you want to be sure that the product carries the Chromax ® logo and the following US Patent Nos. 5,087,623; 5,087,624; and 5,175,156. The Chromax logo ensures that the supplement you are buying contains a patented form of chromium that has been manufactured according to Good Manufacturing Practices (GMPs) and extensively tested for purity and quality.
