From the archived source record

Based on the inspectional findings we have identified serious violations of the Federal Food, Drug, and Cosmetic Act (the Act) and applicable regulations. The inspection of your facility revealed serious violations of FDA’s regulations for Current Good Manufacturing Practice (CGMP) in Manufacturing, Packaging, Labeling, or Holding Operations for Dietary Supplements under Title 21, Code of Federal Regulations (CFR), Part 111 (21 CFR Part 111). These violations cause your dietary supplement products to be adulterated within the meaning of section 402(g)(1) of the Act [21 United States Code (U.S.C.) § 342(g)(1)] because they have been prepared, packed, or held under conditions that do not meet CGMP requirements for dietary supplements. We address your response below, in relation to each of the noted violations. Dietary Supplement CGMP Violations: Your significant violations of CGMP requirements are as follows: 1. You stated that you cannot retain reserve samples using the same container-closure system in which the packaged and labeled dietary supplement is distributed due to facility space concerns. This letter is not intended to be an all-inclusive statement of violations that may exist in connection with your products. You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations. This letter notifies you of our concerns and provides you an opportunity to address them. Failure to adequately address this matter may result in legal action including, without limitation, seizure, and injunction. Please notify FDA in writing, within 15 working days of receipt of this letter, of the specific steps you have taken to address any violations. Include an explanation of each step being taken to prevent the recurrence of violations, as well as copies of related documentation.
