GDI is a family owned company specialized in the development, production and selling of high quality natural food supplements and care products.

We have more than 20 years experience in the food supplement industry and we bring our range of food supplements under the brand name Martera on the market.

The Martera products are free of preservers, colourings and chemical additives and should be of organic certified origin whenever possible.

Our bestseller is the liquid multi-vitamin concentrate Vibracell^®, launched in 1998 and since then steadily growing and successfully sold.

We export our Martera products to nearly all the European countries where we work with a national distributor. Some of our distributors are specialized in visiting doctors, therapists and pharmacies, others are more focussed on the health shops.

We would like to expand our sales outside Europe and are looking for new distributors/importers.

GDI is also active in the commercialising of health improving devices.

We have for instance the Aqua-cel devices that transform tap water into vitalized, energized and living drinking-water with the quality of natural spring water. There are also applications for fruit juices, non-carbonated soft drinks and wine.

We are furthermore the exclusive European distributor of the energizing devices Xierom^TM and Xiermat^TM. You can visit the website www.xierom.com for more information.
