World Class Labs

The role of microbiology in quality control at NOW® Foods is expanding daily to encompass a wide variety of quality and safety issues.

Incoming raw materials and natural food products as well as any supplements formulated and manufactured off site are tested for the presence of undesirable microbes. Materials that do not meet NOW’s stringent specifications are returned to the vendor with an explanation detailing the reason for refusal.



To ensure all products manufactured at NOW remain free of biological contaminants, various sites throughout our manufacturing plant are monitored regularly for the presence of unwanted microbes. In addition to ensure quality, we are also directly involved in the formulation of active bacteria products such as probiotics containing acidophilus. Now Foods has made substantial investment in the development and staffing of an in-house laboratory to meet ever-increasing demands for accurate product analysis of herbal and nutritional raw materials as well as finished consumer products. Our expert team of highly qualified scientists and technicians work in tandem to develop new and improved analytical methods with the highest accuracy and precision possible to ensure NOW Foods’ products will remain among the best the market has to offer.

To assist in this mission, NOW’s recently renovated and expanded laboratory facilities feature state-of-the-art testing equipment including high performance liquid chromatographs (HPLC), a new Fourier transform infrared spectrophotometer (FTIR) and an ultraviolet/visible spectrometer (UV/VIS). Primary analyses are also performed in-house using Gas Chromatography (GC) and Gas Chromatography Mass Spectroscopy (GCMS).

NOW’s analytical chemists are also second to none and widely recognized as being among the industry’s best and most accomplished.
