An FDA 10/18-10/22/21 inspection at the NatureLab Corp. dietary supplement manufacturing facility in Carrollton, TX, found serious violations of the Federal Food, Drug, and Cosmetic Act and FDA regulations. A just-released 7/12 [Warning Letter](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/warning-letters/naturelab-corp-625768-07122022?ref=fdaweb.com) says the inspection found serious violations of FDA’s current good manufacturing practice (CGMP) regulations for dietary supplements that cause the firm’s supplements to be adulterated within the meaning of the law. Specific violations were:

- failing to establish the required specifications for points, stops, or stages in the manufacturing process where control is necessary to ensure the quality of the dietary supplement and that the dietary supplement is packaged and labeled as specified in the master manufacturing record (MMR);
- failing to prepare and follow an MMR for each unique formulation of dietary supplement that NatureLab manufactures, and for each batch size, to ensure uniformity in it finished batch from batch to batch, including all information required by regulations;
- the batch production record did not include complete information relating to the production and control of each batch;
- failing to examine, before packaging and labeling operations, packaging and labels for each batch of dietary supplement to determine whether the packaging and labels conform to the MMR; and
- failing to establish and follow written procedures to fulfill the requirements related to product complaints.

The letter also lists misbranding violations applicable to unidentified company products.

NatureLab was told to respond with a list of specific steps it has taken to address the violations and prevent their recurrence, with copies of related documentation and a schedule for completing the corrections.
