About Us

Quality & Innovations from IronMaxx® Nutrition

Premium sports nutrition - Designed in Germany!

Producing the best sports nutrition worldwide is the goal of IronMaxx®.

The production of highly efficient sports nutrition of the best quality and the constant further development of our products led to the award of the State Prize for Excellent Food Quality by the State of North Rhine-Westphalia. However, this is no reason for us to rest on our laurels - we are constantly working with the greatest passion to offer you supplements that inspire, work and taste great! The integration of the latest study results and the evaluation of practical field research in cooperation with professional sports clubs and our customers have led to permanent innovation in the development of new sports and fitness nutrition at IronMaxx® Nutrition since the company was founded in 2004.

In addition to the basics of sports nutrition in the areas of strength/endurance, muscle building and diet, this includes effective nutritional supplements for health and prevention, intelligent new combinations of active ingredients and improved dosage forms, such as our Tricaps®.

In the area of protein products, for example, IronMaxx® has set a milestone in the evolution of the latest sports nutrition products with the development of water‑based protein powders in over 31 flavors. The sweet spread with the world's highest protein content, IronMaxx® Protein Creme, also comes from us.

Designed in Germany - as a German sports nutrition manufacturer, IronMaxx® is also committed to outstanding quality and seamless quality control.

High performance - the goal is the goal.

Well‑known professional clubs, such as the eight‑time German ice hockey champions, the "Kölner Haie", or the traditional handball club VfL Gummersbach with its unique success story, have relied for years on the efficient sports nutrition from IronMaxx® and on our expertise in the use and mode of action of nutritional supplements.

While in many areas of life the "path is often proclaimed as the goal", our customers usually have a very clear idea of their "dream body" and its desired performance. This passion to achieve their personal goal is something we share with all our partners and customers - be it an athletic body, achieving new personal bests, reducing body weight or achieving sporting team success.

IronMaxx® products have therefore become an integral part of the product range of many European fitness studios, wholesalers, pharmacies and body stores in recent years due to their high quality.
