About the YPSI

The YPSI was originally founded by Wolfgang Unsöld in September 2010 as a personal training studio. Today, the gym and institute is one of the world's leading providers of products and training relating to training and nutrition.

The YPSI has worked with top athletes from over 25 sports since 2010. Including many German champions, European champions, world champions, Olympic medalists and world record holders, as well as 13 athletes competing at the 2014 Winter Olympics in Sochi, three athletes competing at the 2016 Summer Olympics in Rio de Janeiro and one athlete competing at the Summer Olympics 2020 in Tokyo .

There are now YPSI-certified trainers and coaches in over 35 countries on all five continents.

The seminars of the YPSI trainer certification are thus one of the leading trainer certifications worldwide, which are known far beyond the borders of Germany for practical, success-oriented content at the cutting edge of science and practice.

The YPSI Supplements build on this philosophy.

From the innovative formulations of our complexes at the cutting edge of science and practice to the unique quality of the raw materials - our products become what they are through careful, well thought-out selection and processing.

"More competence and innovation for more success in training"

raw materials

In order to guarantee the best quality, we only use high-quality and very strictly tested substances as raw materials for the manufacture of our products.


In order to guarantee the highest level of purity, we work with accredited German laboratories and have our products tested for purity and quality on a regular basis. 

Whenever possible, we do without unnecessary additives such as emulsifiers, preservatives, release agents, flow aids, flavorings, fillers and colorings. However, if these are essential to make a product consumable, we use purely natural, functional substances in the lowest possible doses in order to optimize the product.


Innovation is the top priority for YPSI products. Well thought-out formulations with the highest quality ingredients make the YPSI supplements known worldwide with customers from all over Germany, Europe and as far away as Canada, Brazil, Australia and Japan.

Bioavailability & Bioactivity

Bioavailability indicates how quickly and to what extent a substance can be absorbed by the body. The higher the bioavailability, the more of a substance is absorbed.

And the bioactivity determines what effect substances have in the body after absorption. The higher the bioactivity, the greater the effect of the absorbed substance.

Through optimal recipes and the selection of specific forms of vitamins and minerals, and above all the highest quality raw materials, we ensure that the products can best develop their effect in the body.

Sustainability & Ecology

Sustainable, ecological action is an important part of our work and our responsibility. This is how we pack our products in recyclable cans and recyclable amber glass. And send them in sustainable shipping packaging and adhesive tape made of 100% paper and natural rubber adhesive climate- neutrally by DHL GoGreen .

Made in Germany

All of our dietary supplements are encapsulated and bottled in Germany in IFS and HACCP certified production facilities. In this way, we retain optimal control over the purity and raw material quality of our products.
