Natrol - Quality Uncompromised®

Quality Materials Used In Natrol Products

Natrol buys raw materials from companies located in the U.S. and abroad. Regardless of the country of origin, our extensive quality procedures ensure that Natrol’s products are safe, pure, and meet label claims. Natrol’s Quality Assurance Program involves the following key components:

  1. Vendor Qualification: Natrol’s strict vendor qualification program includes screening by a GMP audit questionnaire, followed by facility audits to ensure we select reliable suppliers. As a result, Natrol has close working relationships with a group of trusted vendors who consistently furnish the highest quality materials.
  2. Ingredient Testing: All ingredients are carefully inspected upon receipt, sampled, and held under quarantine until analytical testing is completed to confirm that they meet all specifications for purity, activity, and physical characteristics. All materials undergo thorough testing prior to release for manufacturing. Any material that does not meet all specifications is rejected. Natrol’s reputation for having strict acceptance criteria and rejecting unsuitable materials is well known throughout the nutraceutical industry.
  3. In-Process Testing: During the manufacturing process, testing is also conducted to assure that each product conforms to the specifications established for it.
  4. Finished Product Testing: All manufactured products undergo final analytical testing to ensure their safety, purity, and activity levels. Final testing includes physical and chemical analyses and microbiological testing to guarantee each Natrol product meets all quality specifications. Sensitive analytical testing is also performed to ensure that our products are below the legal limit (California Proposition 65) for heavy metals (Lead, Cadmium, Arsenic, and Mercury).
  5. Document Control: All aspects of the quality program and test results are thoroughly documented. Traceability of every ingredient used in each of our products is an absolute requirement of our system.
  6. Record Retention: All production and testing records are maintained in safekeeping for several years.
  7. Regular Quality Audits: Natrol undergoes regular quality audits by its licensing and certifying agencies. We also conduct internal audits of our procedures and processes to ensure compliance within our organization.

Our consumers can be assured of the safety and effectiveness of Natrol’s products no matter where the raw materials originate because of the extensive testing and GMP quality procedures we maintain.
