Driven by Science and Experience






Martial arts

“You are what you eat” and “Abs are made in the kitchen”. Everyone knows these statements, but many do not act accordingly. We have over 25 years of experience, scientific and sporting background and just want to give you the best products you can get. For this we like to go our own way and do not compromise in terms of quality and meaningfulness of products. You will receive products from us with:

  • The best raw materials, preferably from the region
  • Own recipes
  • We sweeten naturally with stevia
  • No fillers (your body really doesn’t need that)
  • Produced with state-of-the-art production facilities in Germany

And in all this, the taste is always in the foreground. Even if everyone says that their product is “delicious”. We see this as a promise. Take us at your word here!

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.

Quality is important to me, because if I do my best during training, I want to support success with good products.

If you have your diet in mind every day, you will know how pleasant it is when taste and effect really fit.

I pay attention to high quality in the daily diet and therefore it is equally important to me that my supplements are of a very high quality.

Especially in the preparation of the competition, it helps enormously when you feel physically how the supplements help you to achieve your goal.

Especially with so many games we do in a season, it is important to regenerate optimally. The right supplements really help to give your best.
