Product Quality
Quality begins in selection, where only the finest herbs and raw materials are obtained. The companys global sourcing of raw materials ensures that the highest quality products are chosen from each harvest season. After being harvested, these materials are shipped to the manufacturing facility, where they are subjected to a series of in-depth quality control tests to ensure purity, potency and cleanliness. Nature's Sunshine meticulously tests all of the raw materials we receive. Our QA testing continues throughout the entire production process. In all, we use more than 300 tests and procedures to ensure the quality of the raw materials we use and the finished products we sell.

Once a product has been produced, it undergoes a battery of tests to assure consistency, quality and potency. The finished product is audited by inspectors for bulk weight, liquid volume, bottle count, bottle sealing and legible lot number. Samples are then given to the QA labs so scientists can complete testing according to finished product specifications. After all tests are completed and the product has passed the inspections, Quality Assurance will release the product. The batch record and a sample of the finished product are retained for future reference. If a customer has a question about a product, QA can refer to the retention sample of the lot in question.

Every test we conduct leads to better product quality, and excellence in product quality is what has put our products where they are today--at the top of the industry. You can be assured that with each new product we develop and manufacture, our commitment to excellence will continue. The following represents a few of the important tests we conduct:

• Disintegration testing (tablet)
• Dissolution testing
• Foreign Organic/Inorganic Matter
• Heavy Metals testing
• High Performance Liquid Chromatography (HPLC)
• Microbiological Testing
• Organoleptic testing
