Core values


In order to be able to deliver ‘virtuoso’ quality, we choose to work exclusively with the best producers. An important partner in this is Laboratorium Medisan, located in Heerenveen. Laboratorium Medisan is known as a developer of high-quality products based on active biological ingredients to support health. This company based in the province of Friesland is FSSC-22000 certified (international certificate for food safety) and has a modern pharmaceutical infrastructure (1,400 m2 clean room) in accordance with the internationally applicable GMP classification. Together with Laboratorium Medisan, Virtuoos develops supplements of the highest quality.


Our products are always approved by the Nederlands Zekerheidssysteem Voedingssupplementen Topsport (Anti-Doping Authority for the Netherlands, NZVT). Because we have each individual batch inspected, you can be sure that you are buying a pure product. In addition, we also test all individual raw materials and keep strict control during the production process, so that no contamination can occur.


For Virtuoos, co-creation is an essential part of product development. By involving the sports sector in this process, we are able to develop new and innovative nutritional supplements that meet the high quality requirements set for top-class sport. In doing so, we make use of the knowledge and experience of various professionals in the sports sector, including:

  • Top athletes
