About us

At home in equestrian sports for decades

Michael and Petra Stroetmann have dedicated their lives to horses. During his youth, Michael Stroetmann was successful as a show jumper and bred racehorses. As the founder of EQUISTRO® Pharma GmbH, he developed many supplements/feeds for horses that are still successful today.

The two initially developed strotonin for their own use in close cooperation with veterinarians. Due to the excellent effect and the great demand among experts, they have decided to bring another innovative supplementary feed onto the market. Since then, her son Max and his partner Lea have been responsible for setting up the “family start-up”.

... take over the development of the "family start-up" and the distribution of Strotonin. At the beginning of 2023, we initially introduce Strotonin to veterinarians and veterinary clinics. In December, we are represented with Strotonin for the first time at the international Festhalle horse show in Frankfurt - a complete success!
