About us


Behind all COLPROPUR products is PROTEIN, S.A., a company that has spent the last 40 years developing and manufacturing ingredients for high quality natural food products. We specialize in producing hydrolyzed collagen protein, in which we are one of the main companies in Europe.

We are also a dynamic and well-prepared team with immense confidence in our products. This makes us unstoppable.

Thanks to our innovative spirit, we have overcome major challenges and have created a manufacturing plant designed by our own technicians and engineers with unique technology that only uses processes in which chemical products are not used at all. This allows us to guarantee the maximum quality of our products and absolute respect for our environment.

In 2008, after years of research with the collaboration of the Institut Municipal d’Investigacions Mèdiques (IMIM; Municipal Institute of Medical Research), the Rheumatology and Dermatology Departments of Barcelona’s Hospital del Mar and the Dutch TNO Institute, we were able to assess the efficacy of our natural, pure and highly digestible hydrolysed collagen protein. These results made us decide to put it onto the market under the name COLNATUR®, so that it would be available for those sectors of the population who need to supplement their diet with this protein.

Over the course of time we have developed a range of natural and very effective collagen-based products with health functionality. It is a product that enjoys scientific and medical recognition.

Over the years, we have developed the COLPROPUR range, nutritional supplements based on our COLPROPUR® natural and very effective collagen, with beneficial effects on joints, bones, muscles, teeth and skin.
