If nutritional supplements, then Cologne List®.

Cologne List® offers athletes and those around them help and advice with regard to the use of nutritional supplements. The list only includes products that have undergone rigorous tests for specific doping substances, minimizing the risk of an anti-doping rule violation.

Many athletes of different levels use nutritional supplements. Cologne List® evaluates neither the reasonableness nor the effect of taking nutritional supplements. Cologne List® aims to minimize the risk of committing an inadvertent anti-doping rule violation (for testing pool athletes) and reduce health risks.

Nutritional supplements are regulated as foods. Regulations and quality control standards for nutritional supplements are less strict than those for pharmaceuticals. As a result, there is an increased risk of contamination (contamination with substances that are not declared on the label) or adulteration (intentional addition of mostly banned substances).

Cologne List® minimizes the risk of doping.

A first study conducted in 2004 found that approximately 15 percent of nutritional supplements acquired in 13 different countries contained anabolic steroids (primarily prohormones) that were not declared on the label. In Germany, about 11 percent of the tested nutritional supplements contained prohibited anabolic steroids. The creation of Cologne List® led, amongst other things, to a fundamental improvement of the situation. Products that undergo voluntary laboratory testing by recognized anti-doping programs such as Cologne List® subsequently present a far lesser risk of contamination with banned substances.

Service for testing pool athletes

It is advisable for testing pool athletes to seek advice from a sports nutritionist or a medical doctor before taking any nutritional supplement. Moreover, testing pool athletes should only use batch-tested supplements. This is where the new Cologne List® product availability service comes in.

Important: the listing of a product on Cologne List® does not mean that the product is strictly free from banned substances. It simply means that the risk of contamination is significantly reduced. It is the athlete's sole responsibility to evaluate any potential risk of an anti-doping rule violation as well as any possible health risk.

Please note: we cannot provide any information on products that are not listed on Cologne List®.

Cologne List® is a service platform initiated by the Olympic Training Center Rhineland (Olympiastützpunkt Rheinland) in cooperation with the National Anti-Doping Agency Germany (NADA) and the Athletes' Commission of the German Olympic Sports Confederation (DOSB). It should be stressed that Cologne List® is not a recommendation for athletes to take nutritional supplements. Our goal is merely to educate and create awareness.
