NOW® Foods Continues to Employ Industry-Leading Adulterant Testing Method to Safeguard Product Safety and Purity
Bloomingdale, IL (July 26, 2013) - NOW Foods continues to be dedicated to providing safe and high quality products to consumers and, in 2009, began developing and validating a rapid, inexpensive, and sensitive tool to identify potential adulterants in dietary supplement raw materials that can be used to screen for both known and emerging adulterants. Understanding the importance of industry-wide testing, NOW Foods published their method in the peer-reviewed journal, Vibrational Spectroscopy (Champagne and Emmel, 2011), so that it would be available to the industry as a whole.
The method continues to be a valuable tool for adulteration testing today. In fact, two recently published methods have adapted NOW Foods’ method to distinguish between counterfeit and authentic prescription drugs (Ortiz et al., 2013; Anzanello et al., 2013). These utilize similar analytical FTIR (Fourier Transform Infrared) techniques with the addition of a mathematical process called Principal Component Analysis (PCA). These methods are an extension of the work initiated by NOW Foods, further demonstrating the utility and value of the methodology developed by NOW scientists. Anzanello et al. (2013) state that NOW Foods’ method “…[becomes] fundamental for detecting the presence of multiple PDE-5 inhibitors with a single test,” an integral step in identifying adulterated materials.
Since its inception in 2010, NOW Foods’ method for adulteration screening has been used to test over 1,400 incoming lots of specific raw material for the presence of adulterants, including erectile dysfunction drugs, weight-loss drugs, melamine and steroids. NOW Foods’ scientists continue to adapt the method to include novel adulterants as they appear, helping to ensure the quality and safety of the dietary supplements manufactured by NOW Foods and the entire natural products industry.
NOW Foods considers the safety and quality of natural products to be of the utmost importance, and will continue to employ every means at their disposal to ensure the identity, purity and safety of every product that they produce.
