The abbreviation GSE stands for Grapefruit Seed Extract, a product which has laid the foundation for the so-named company in 1994. Back in the 1990s the grapefruit seed extract used to be recommended for homeopathical treatment as a boost for the immune system, but was not available on the German market.. What started as an import business from the United States soon transformed into product making, with an own and improved formula. Our grapefruit seed extract (currently commercialised under the brand name CitroPlus) was the world’s first in organic quality and offers now various concentrations of bioflavonoids. Driven by our innovation spirit and resorting to tens of years of experience and competence in the fields of naturopathy and biology, as well as to a vast network of suppliers of raw materials, we have continuously developed our assortment of food supplements, which we export to more than 25 countries. Our product range comprises more than 35 items (some of them are also world's first), among others the Naturland certified algae, various antioxidants, cell protecting and energy level improving products and of course, our highly innovative phyto vitamins. These phyto vitamins are also organic, exclusively plant-based and contain no synthetic additives whatsoever. Additionally, they contain the plants' secondary substances, which facilitate an optimised absorption of the nutrients by the human body, as the whole plant is better than the sum of its parts. GSE is located in Saarbrücken (Germany) and has a headcount of 25 employees.
