Quality Control
Testing Methodologies
We utilize a variety of methods to test all raw materials upon receipt making sure that they meet our uncompromising standards. Tests confirm identity and potency and screen for impurities: heavy metals, insecticides and microbes. All raw materials are quarantined until accepted or rejected by the QC department. Finished products undergo final testing before being released for packaging.
Validation and Documentation
Validation helps us to assure that each batch meets predetermined specifications. Inspections are conducted throughout the manufacturing process monitoring weights, hardness, conformation, disintegration and color. Documentation is conducted on all procedures and maintained at Highland Laboratories.
Raw Material Procurement & Analysis
With over 38 years in the industry Highland has developed long term relationships with the best growers and manufacturers. Our vendor evaluation process includes auditing their facilities, processes and standards as well as verification of certificates of analysis. We maintain a complete track of lot/batch numbers providing a full history of each raw ingredient in any given formula throughout the life of the lot/batch number.
