Did you know almost 1 in 10 supplements is contaminated with ingredients or compounds prohibited in sports? This research has discovered that some dietary supplement products contain low levels of substances prohibited by the World Anti-Doping Agency (WADA) and other sporting organizations.
The Prohibited List contains three categories of restricted substances and is considered one of the foundations of the World Anti-Doping Code. It is reviewed annually through an extensive consultation process facilitated by WADA. The three categories of prohibited substances include:
- Prohibited at All Times
- Prohibited In-Competition
- Prohibited in Particular Sports
Sources of Contaminated Products
- Cross-contamination usually occurs due to inadequate cleaning procedures. In manufacturing, a variety of different products can be produced within the same facility, causing some products to pick up ingredients from previous production runs.
- Poor quality sourcing for raw materials could unknowingly lead to contamination because of varying quality control regulations among different areas around the world. These imported raw ingredients may arrive contaminated, affecting the full production.
Many athletes have had their careers end early from not realizing they were using products containing prohibited substances. To ensure the safety and integrity of all athletes from inadvertent doping, Paragon Laboratories has continued its mission of providing the highest quality dietary supplements by receiving the Informed-Sport Certification.

Working closely with supplement manufacturers and suppliers, the Informed-Sport certification program comprises:
- Product testing with ISO17025 accredited methods
- Thorough manufacturing quality control and product labeling audits
- Pre-registration testing of products before program entry
- Regular testing to maintain certification
With over two decades of analysis from tens of thousands of supplement and raw material samples, LGC has proven that the risk of using regularly tested products is better than products that undergo no testing. There are currently 225 certified brands, totaling over 1,000 products globally.
