comprehensive testing
NOW’s dedication to testing raw material through finished product sets us apart from many other manufacturers. We maintain in-house laboratories, instruments, and staff that allow us to analyze faster, be more adaptive, and provide fresher products, all at reduced costs for our customers.
NOW Performs Over 16,000 Analyses and Tests Each Month
When it comes to guaranteeing the quality of more than 1,400 clean, natural products, testing and scientific analysis make the difference. Very few companies, if any, have the facilities, instrumentation, and staff to test their ingredients and finished products in-house like NOW does. We perform approximately 16,000 tests on a monthly basis, all of them in our own facilities using our own cutting-edge instrumentation and performed by our own trained scientists.
