How do you measure quality?

When it comes to guaranteeing the unsurpassed quality of our 1,500+ natural products, testing and scientific analysis make the difference. Our dedication to comprehensive testing in the most extensive in-house labs in the industry sets us apart from other natural products manufacturers. Did you know that NOW performs more than 31,000 analyses and tests each month? We test incoming raw materials and ingredients, in-process ingredients, and finished goods to ensure our products meet or exceed CGMP standards established by the U.S. Food and Drug Administration (FDA) in our ISO-certified, world-class labs.

 

We have one of the few manufacturers in the natural products industry to own and operate its own in-house laboratories. In fact, we don’t just have one, we have several:

• Sample Preparation Lab – Analytical chemists employ a wide range of extraction procedures and equipment to separate compounds of interest from diverse sample matrices in preparation for subsequent analysis using a variety of analytical instruments.

 

• Physical Testing Lab – Our physical testing laboratory serves as the hub for all of physical attribute testing. Here, we meticulously analyze key ingredient attributes including weight, thickness, density, dissolution, and melting point, among others, to uphold the standards of identity and quality.

 

• Analytical Testing Labs – In our analytical testing laboratories, we house some of the most advanced analytical instrumentation, which includes gas chromatography, high-performance liquid chromatography, and other sophisticated equipment. We employ a diverse range of analytical techniques and instruments to identify chemical constituents and to guarantee the absence of contaminants and adulterants in raw materials and finished products.

 

• Research & Development Lab and Pilot Plant– We engage in the continual development and testing of new formulations and product concepts. Our ongoing objective is to identify novel combinations of complementary ingredients that can effectively contribute to the enhancement of overall health.

 

• Microbiology Lab – Microbiological screening stands as a critical step in ensuring the safety and quality of our natural products, encompassing supplements and natural foods. Our meticulous testing program is specifically tailored to uphold the safety standards of all our products.

Additionally, We have a dedicated Method Development team that focuses on developing and validating in-house testing methods that are suitable for the materials being tested. The team is also involved in research projects that concentrate on new approaches for testing chemical constituents and contaminants.
