Dietary supplement coatings to protect your health ingredients and release them at the right time, place and duration

There are many health ingredients that require formulations with well-defined release profiles to ensure they are best absorbed at specific sites within the GI tract such as the stomach, colon or small or large intestine. EUDRAGUARD® functional supplement coatings can not only be used to create precise immediate, delayed or sustained release profiles, but help to enhance solubility to improve ingredient absorption and increase bioavailability. Other health ingredients require EUDRAGUARD® coatings to overcome stability challenges caused by gastric juices, bile acid or enzymes in the small intestine. Some health ingredients can require a specific coating layer to protect the supplement from moisture or other ingredients or reduce the risk of reflux. The protective properties of EUDRAGUARD® products can not only address these formulation needs but as a further advantage also improve the consumer experience by masking unpleasant tastes or odors or enhancing swallowability.

A broad portfolio of dietary supplement coatings providing the flexibility to deliver specific formulation or application outcomes

Our portfolio of EUDRAGUARD® supplement coatings for targeted functionality for nutraceutical effectiveness and the reliable release of health ingredients at the right time and place includes:

  • EUDRAGUARD® protect is designed for taste and odor masking, the protection of ingredients from moisture or other ingredients, to enhance solubility, and ensure immediate release in the stomach.
  • EUDRAGUARD® control can be used, in combination with alginate, to achieve a range of controlled delivery outcomes, such as the protection of sensitive ingredients from acidic conditions in the stomach, avoidance of mucosal irritation, targeted release at a specific pH or sustained release over during passage through the GI tract.
  • EUDRAGUARD® biotic is ideal for use with prebiotics, probiotics and other health ingredients that are targeted for precise colonic delivery.
