What does a dietitian-nutritionist's website in Spain have to comply with?
The same as any health professional's website: a legal notice with your professional association and registration number, forms that do not pile up health data, and advertising without promised cures. Plus two things of your own: never promise anyone they will lose weight and, if you recommend or sell products, do not claim effects that are not authorised.
Your title, said right
The health profession in Spain is Dietista-Nutricionista (Ley 44/2003 and Orden CIN/730/2009), with the degree in Human Nutrition and Dietetics. Many people advertise as a "nutritionist" without that training, so put your exact title, your professional association and your registration number on your site: it is what sets you apart, and the LSSI asks for it in the legal notice.
What you cannot promise
- The rule on advertising with a health purpose (Real Decreto 1907/1996) forbids suggesting slimming properties and guaranteeing a cure. "Lose 10 kilos in a month" is exactly that.
- It also forbids presenting something as a substitute for ordinary food in pregnancy, breastfeeding, childhood or old age.
- And using patient testimonials as a lure.
Before-and-after photos
A patient's before-and-after photo is health data and, at the same time, a promised result. If you still want to use one, you need their explicit written consent (the GDPR asks for it for health data) and they must not be recognisable. Your professional association may have stricter rules.
If you recommend or sell products
- A health claim about a food or a supplement ("boosts your immune system") can only be made if it is on the European Union's list of authorised claims (Regulation 1924/2006).
- Affiliate links are advertising, and the LSSI requires that to be visible: say so next to the link, not on a separate page.
Online consultations
If you do video consultations or send questionnaires before the first visit, the tool should sign a data processing agreement with you. And questionnaires with health data are better inside that tool than in a form on your website.
What I do
The websites I build for practices come with the legal notice and privacy policy, a contact form that does not store messages and no tracking cookies. From €890 + VAT, at a fixed price agreed before starting.

This is a practical explanation, not legal advice. When in doubt, your professional association has the final word.
