All our raw materials are accompanied by guarantees and certificates from the companies that supply YIOTIS S.A. These guarantees state that the raw materials comply with the European Legislation. Therefore, YIOTIS S.A. does not use any Genetically Modified Raw Materials (certificate of non-mutated feedstock) and the Company makes absolutely sure of this by carrying out thorough analysis of raw materials on receipt. This analysis is done in the Company's laboratories, using specialised high-resolution equipment.
