Nutritional supplements are concentrated sources of nutrients with a physiological or nutritional effect. Before selling in Spain, the product must be declared to the Spanish Agency for Food Safety and Nutrition (AESAN — Agencia Española de Seguridad Alimentaria y Nutrición) and have a corresponding label in Spanish.
On Amazon.es, sellers must create an optimised listing with title, images, authorised claims and an effective sales strategy.
