CERTIQUALITY is a not-for-profit organisation serving companies, accredited to certify management systems relating to Quality, Environment, Safety and Product Certification.  Certiquality certifies and guarantees that ESI Aloe Vera juices:
– are free from pesticide residues and chemical fertilizers
– contain no less than 7.000 mg/liter polysaccharides



ESI cooperates with universities, research institutes and Hospitals, both in Italy and abroad, to test the effectiveness and safety of the products. This rigorous, pharmaceutical approach applied to natural products provides the consumers with the best possible quality.



NATURCAPS are plant based capsules which are, in fact, made with cellulose, a natural constituent of plant cell walls. It’s only logical to wrap the beneficial properties of plants and their extracts in a plant-based (and not animal-based) coating. The capsules have been approved by the Vegetarian Society.


Naturcaps retard

NATURCAPS® RETARD BIPHASIC: this ESI patented technology allows the body to absorb nutrients gradually and completely. Each capsule contains 4 microtablets, which can also be gastroresistant; they disintegrate at different times, allowing a gradual, constant release of the ingredients and guaranteeing the body sufficient time to absorb and transport the active principles throughout the body, thus providing a prolonged action (called RETARD action).


Gluten free

Following the spread of celiac disease and gluten intolerance, all ESI® products are made “gluten-free”. According to the regulation CE / 41/2009 and subsequent CE / 828/2014 ESI® products contain less than 20 ppm gluten (0.002%) and are therefore suitable for celiacs. The absence of gluten is clearly indicated on the packaging with an easily recognizable symbol.



To complete the information on ESI® products, the consumer will find a small symbol on the packaging showing whether the product is suitable for vegetarians and/or vegans according to the origin of the raw materials.
