Founded in 1975, ESI was one of the first Italian companies to believe in and invest in the natural sector, proposing innovative, high-quality formulations. By applying analytical methods recognised by the official pharmacopoeia, studying the chemical and herbal properties of raw materials, their use and optimisation, ESI is able to produce formulations that combine innovation, safety and quality. The research, conducted in collaboration with major Italian universities and research centres, allows the company to stay at the forefront of product development. The strict selection and accurate inspection of raw materials have enabled ESI to establish itself as one of the main manufacturers in the natural products sector and one of the most widely distributed Italian supplement companies in the world.
