Supplementation and nutrition are constant problems that concern elite athletes. Supplements are usually taken in large amounts, but as much as 20% of presumably benign nutritional supplements are contaminated with doping agents. This can be the cause of various side effects and positive doping tests.

Having recognized the problem, The Anti-Doping Agency of Serbia, The Sports Medicine Association of Serbia and Institute of Bromatology, Faculty of Pharmacy, Belgrade will organize The First Congress of Food Supplements from 15 till 17 March 2007. Dr Günter Gmeiner, Director of Seibersdorf Anti-Doping Laboratory is one of lecturers of this event.
