As a supplier and producer of herbs, we place great emphasis on the responsible handling of all our products. Each step in the production process is closely monitored to ensure that high quality products are produced. The high quality of the herbs is guaranteed by our own selected seeds, contract cultivation, specific drying methods and the quality analyses we perform. 

By selecting and breeding active ingredients such as valeric acid from Valerian, VNK has given us the experience our customers value. In our contracts we lay down the specifications for contents. Product specifications are available and a detailed certificate of analysis will be enclosed for each batch we offer. We guarantee the high quality of our products at all times through our consistent batch control programme.
