Manufacturing of NOW Supplements

Testing is the difference

Purchasing the best quality ingredients is just the first step in the manufacturing process. Once our ingredients are received, our quality team begins testing to verify their identity and purity in our state-of-the-art, in-house analytical laboratories.

Very few companies have the facilities, instrumentation, and staff to test their products and ingredients in-house. At NOW we perform approximately 16,000 tests on a monthly basis, all of them in our own facilities using our own instrumentation and performed by our own technicians.

The tests they perform include screening to ensure the absence of adulterants and contaminants, and analyses to verify identity and potency. Once the ingredients have been combined in a product, the finished product is tested for attributes such as absorption, bioavailability and break-down after ingestion.

From beginning to end NOW takes the necessary steps during manufacturing to ensure purity, potency and safety.

Good manufacturing practices

Since 1968 we’ve been meeting and exceeding natural product manufacturing regulations, even when none existed. We were one of the first manufacturers to seek certification through the Natural Products Association’s (then the NNFA) inaugural GMP (good manufacturing practices) program in 2000, for which we received an ‘A’ rating, and we’ve been recertified with an ‘A’ rating every year since.

The NPA GMP program is a voluntary certification program comprised of standardized manufacturing and quality control practices. Companies seeking certification must undergo intense and thorough audits of their manufacturing, quality control and quality assurance processes and procedures, and must do so annually to maintain their good standing.

NOW is also in full compliance with the Food and Drug Administration’s more recent Current Good Manufacturing Practices, or cGMP. Introduced in 2007, federal cGMPs are published federal requirements for companies engaging in the manufacture, packaging, labeling or holding of dietary supplements.

These cGMP requirements assure the proper design, monitoring and control of manufacturing processes and facilities. They also establish minimum requirements for sanitation, record-keeping, packaging and labeling operations, and more.

Our adherence to manufacturing GMPs, our insistence on choosing only the best ingredients, and our commitment to testing and safety are what set us apart from other natural product companies.

With our own state-of-the-art manufacturing facilities and in-house laboratories, we’re well-equipped to ensure the quality and safety of all NOW® products.
