Quality in Dietary Supplements

Certain categories of products that are frequently incriminated (e.g. sexual enhancement, weight management and sports nutrition dietary supplements) are subject to special monitoring to ensure the absence of prohibited pharmaceutical ingredients. In this catalogue, AXIO has summarized all the proficiency testing samples that laboratories may require to meet their proficiency testing requirements. Read on to see our extensive analyte lists – from nutritional testing and element testing, to authenticity and compliance labelling, and the huge range of matrices we offer, from raw materials to finished products.

It is increasingly common for people to supplement their diets with vitamins, minerals, botanicals, or fatty acids to positively affect various aspects of their health. This trend is driving a boom in the supplements industry, but recent scrutiny has also called into question the safety and effectiveness of many of these products. Still too frequently, dietary supplements are in the spotlight for the wrong reasons. These include discrepancies between advertised and actual concentrations of active ingredients, as well as the presence of contaminants and toxic compounds in some products. To better meet the demand for quality and safety, some retailers require their selling partners to verify that their dietary supplement products meet their policy through testing conducted by a third- party testing, inspection and certification organisation.
