DR Healthcare España, S.L.U.

DR Healthcare España, S.L.U. is a Spanish biomedical company founded in 2007 in Barcelona. It specialises in the research, development and production of diamine oxidase (DAO) enzyme supplements, offered as food supplements designed to accompany dietary routines for people who experience discomfort linked to histamine-rich foods. The company describes DAO as an enzyme naturally present in the body that is involved in the metabolism of histamine from food in the small intestine, and positions its products as a way to support informed dietary choices rather than as medicines. The company states that it is the only company in Europe with a facility specialised in the production of DAO enzyme, and that it works with DAO from both animal and plant sources. Its research is organised around three areas: molecular biology research focused on histamine at a physiological level; biomedical research on nutrition and metabolic disorders involving limited, impaired or disturbed capacity to take, digest, absorb, metabolise or excrete ordinary food or certain nutrients; and applied clinical research on DAO deficiency, its causes, dietary management and evolution. DR Healthcare markets its DAO enzyme food supplements under a range of products aimed at consumers who want to enjoy food with confidence. The brand's communication emphasises everyday wellbeing, the role of dietary histamine, and practical support for food choices when eating out, travelling or sharing meals. The company operates from Spain and presents itself as serving the European market, with an English-language website alongside its Spanish presence. As a private company, DR Healthcare does not disclose a stock listing. Its identity is closely tied to the DAO enzyme category, where it combines supplement manufacturing with clinical and nutritional research. The company's stated mission is to help people manage dietary histamine through enzyme supplementation based on selected ingredients naturally containing DAO.

DR Healthcare was founded in 2007 in Barcelona, Spain, as a biomedical company focused on DAO enzyme supplements. From its base in Barcelona, the company built its activity around the research, development and innovation in the production of diamine oxidase (DAO) enzyme, working with both animal and plant sources. This focus placed it in a specialised niche at the intersection of nutrition, enzyme science and clinical research. A central element of the company's history is its claim to be the only company in Europe with a facility specialised in the production of DAO enzyme. This production capability, together with its research programmes, has shaped its identity as a manufacturer-researcher rather than a purely commercial supplement brand. The company organises its research into three areas: molecular biology research particularly on histamine at a physiological level; biomedical research on nutrition and metabolic disorders involving limited, impaired or disturbed capacity to take, digest, absorb, metabolise or excrete ordinary food or certain nutrients; and applied clinical research on DAO deficiency, its causes, dietary management and evolution. Over time, DR Healthcare has developed a consumer-facing range of DAO enzyme food supplements marketed under the idea of enjoying food with confidence. The brand's messaging addresses people who suspect that histamine-rich foods are not well tolerated or that histamine is not naturally broken down, and who seek practical support for dietary decisions in daily life, when eating out, travelling or sharing meals. The company maintains an English-language website and presents itself as serving the European market from Spain. As of the available evidence, DR Healthcare remains an active private company headquartered in Barcelona. Its history is one of sustained specialisation in the DAO enzyme category, combining production facilities, research areas and a supplement range aimed at dietary histamine management.
