Rainer is our "brain", CEO, founder and by the way also food chemist and managing director of several major German brands. Above all, he has been an athlete since he was a boy. So he knows what it takes to get through his diet and achieve his goals. For his own brand (which is therefore also called Z KONZEPT), only the best is good enough for him. He stands for the quality of the products with his name. And we think you'll feel that.
