Nutraceutical coatings

Nutritional coatings

Functional coatings for nutraceuticals.

Across the globe, there is a growing market for nutraceutical products. In the USA, for example, 72 percent of people currently take at least one nutraceutical supplement.

However, there is a need to demonstrate that nutraceuticals can deliver on their health promises. Currently, four in ten consumers are worried that they do not absorb enough of the nutrients in their supplements – and 58 percent of supplement users want scientific proof of ingredient effectiveness. In a nutshell, consumers want nutraceuticals that actually work.

Experts at Evonik have taken up the challenge and have developed the EUDRAGUARD® toolbox for targeted delivery, improved uptake into the body and better bioavailability. EUDRAGUARD® functional, water-based coatings enable targeted delivery of ingredients to all parts of the gastrointestinal (GI) tract and include unique gastro-retentive formulations: EUDRATEC® GRS.

EUDRAGUARD® coatings provide an exceptional visual and tactile experience. They can be tailored to your specific requirements including color matching to maximize the attractiveness of your product to consumers. They are also highly versatile, can be used in diverse applications and are ideal for soft gel capsules, hardshell capsules, tablets and other solid oral dosage forms.

Moreover, EUDRAGUARD® coatings can be applied quickly and easily using standard coating equipment at low spraying temperatures to safeguard the effectiveness of the health ingredients. They meet regulatory requirements in the world’s major nutraceutical markets. They are generally recognized as safe (GRAS) in the USA and have been granted E-numbers in the European Union.
