Purity & Quality

In-House Laboratory Testing

The key to comprehensive quality control is the use of an in-house laboratory. Having an in-house, state-of-the-art laboratory is absolutely necessary to manufacture superior dietary supplements. Thorne Research's laboratory is a primary component to achieve our mission of maintaining strict control over every aspect of manufacture and quality and is an integral piece of our TGA certification. Our in-house laboratory allows for timely, accurate, cost-effective testing that ensures every product, from raw material to finished goods, meets all quality requirements.

Thorne Research's state-of-the art lab equipment includes:

• Inductively Coupled Plasma Spectrometer (ICP)
• High Pressure Liquid Chromatograph (HPLC) with Series 200 Diode Array Detectors and Series 200 Fluorescence Detectors
• Gas Chromatograph/Mass Spectrometer (GCMS) with Flame Fluorescence Detector and Electron Capture Detector
• Near-Infrared Spectrophotometer
• Microbiology lab
• Peroxide analysis
• U.S.P. dissolution

Every batch of every ingredient we receive is quarantined and tested for identity and purity before being allowed to be used in any Thorne Research product. Some of our products are tested again after the mixing phase of manufacturing to ensure a homogenous mix of ingredients has been obtained. Then, every finished product is tested again before being released for sale. Such stringent attention to quality control is extremely difficult to accomplish without a state-of-the-art, in-house laboratory.
