From August 31 to September 3, Krakow (Poland) was a host town for the 41st ESPEN Congress on Clinical Nutrition and Metabolism. Over 3000 attendees from all around the world created a fast-paced atmosphere, and we were there to witness it and contribute it a bit. Our presentation on novel ionic liquid creatine formulation for better tissue energy metabolism have attracted an interest from both delegates from academia and industry, perhaps opening a route for future collaboration. Besides several excellent symposia, ESPEN 2019 and Krakow will be also remembered by great Polish food and hospitality. The abstract of our presentation is published in Clinical Nutrition supplement and could be found here.
