How the profession is regulated

Spain recognises the Dietista-Nutricionista as a health profession under the Law on the Organisation of Health Professions (Ley 44/2003). Practitioners hold a four-year university degree in Human Nutrition and Dietetics (Grado en Nutrición Humana y Dietética), which includes clinical and community placements. Professional colleges (colegios oficiales) exist in most autonomous communities and are coordinated nationally by the Consejo General de Colegios Oficiales de Dietistas-Nutricionistas. Membership of the relevant college is required to practise in regions where a college exists.

Spain's single-profession model avoids the dietitian-versus-nutritionist split seen in many countries. Older "técnico superior en dietética" vocational qualifications also exist, with a narrower scope. Read dietitian vs nutritionist for how Spain compares.

The workforce

The General Council of colleges coordinates the profession nationally; we will add a verified count of registered professionals here when we have read one on an official page. A recurring issue in Spain is the limited number of dietitian-nutritionist posts in the public health system: many hospitals and primary care centres employ few or none, so the profession is concentrated in private practice, sport, industry, catering and education. Professional bodies continue to campaign for their inclusion in public primary care.

Strengths of the Spanish market

• One clear regulated profession with university training.
• A Mediterranean food culture that supports healthy eating messages and a strong food industry.
• Barcelona's trade show. Vitafoods Europe, Europe's leading nutraceutical event, takes place at Fira Barcelona Gran Via from 18 to 20 May 2027^[1].
• Domestic brands. Ana María Lajusticia, known for magnesium and collagen, Soria Natural in herbal products and Laboratorios Ordesa in infant and clinical nutrition are long-established Spanish companies.
• Large food retail. Supermarket groups such as Mercadona shape consumer food choices and own-brand supplements.

Opportunities

For practitioners

Private practice, sports nutrition, eating disorders, weight management and digital consultations are strong fields. Collective catering, schools and nursing homes employ dietitian-nutritionists, and the food and supplement industry recruits for product development and regulatory roles. Inclusion of dietitian-nutritionists in public primary care, if it advances, would open many posts.

For companies

Spain's supplement market is growing, with pharmacies, herbalists (herbolarios), supermarkets and online platforms as channels. Magnesium, collagen, vitamins, probiotics and sports nutrition are popular. Hosting Vitafoods Europe makes Barcelona a meeting point for the whole European industry.

How food supplements are regulated

Spain implements the EU Food Supplements Directive through Royal Decree 1487/2009. Before first marketing, companies notify the product to the competent authority: AESAN, the Spanish Agency for Food Safety and Nutrition, or the health authority of the autonomous community where the company is based, depending on circumstances. Products must use permitted vitamins and minerals and authorised health claims. Plants follow national lists and guidance, and some herbal products sold in herbalists fall under medicine rules. AESAN publishes reports and recommendations on the safety of supplement ingredients.

Public health priorities

Spain's NAOS strategy (nutrition, physical activity and prevention of obesity), coordinated by AESAN, has run since 2005, with programmes on childhood obesity, food reformulation and school food. Spain adopted Nutri-Score as a voluntary label, and regional governments, such as Catalonia, have introduced taxes on sugary drinks. The Mediterranean diet is promoted as a national health and cultural asset.

Practical notes

For internationally trained dietitians

EU qualifications are recognised under the EU Professional Qualifications Directive; non-EU degrees require homologation by the Ministry of Universities, which can involve additional training or exams. Spanish language proficiency and college membership are needed to practise.

For companies entering Spain

Notify each product to AESAN or the regional authority, check vitamin, mineral and plant ingredients against Spanish lists, use authorised health claims, label in Spanish, and plan pharmacy, herbalist and online distribution. Exhibiting or visiting Vitafoods Europe in Barcelona is the most efficient way to meet European partners^[1]; see the events calendar.

How Spain fits the global picture

Worldwide, 2.6 billion adults were living with overweight in 2024, and 940 million of them with obesity^[2]. Diabetes affects 589 million adults aged 20 to 79^[3]. The global dietary supplements market was valued at US$209.5 billion in 2025 and is forecast to reach US$431.7 billion by 2033^[4]. Those three numbers frame demand for dietitians and nutrition products in every country on the Global Hub.
