Versatile plant-based alternative to gelatin


SeaGel® technology offers a plant-based alternative to gelatin to produce soft capsules. Naturally derived from non-animal sources, our SeaGel® technology is easy to use, versatile and proven effective. It maintains structural integrity under high temperatures and can deliver a pure, superior quality product, time after time. 

Without compromising the efficiency and potency of the natural ingredients within the supplement, SeaGel® delivers an exceptional range of benefits for dietary supplements manufacturers.

  • Addresses the needs of vegetarians and vegans who are opposed to ingesting animal-based gelatin soft capsules by providing a seaweed extract source.
  • Follows non-GMO, vegan, vegetarian, Halal, Kosher and ‘clean label’ designations.
  • Adapts to many capsule brand strategies, including different capsule colors, sizes, shapes and printing. 
  • Easily adjusts to existing gelatin operations, requiring minimum capital investment to implement.
  • Withstands high temperatures and humidity without risk of cross-linking or melting capsules.
  • Enables efficient processing, outstanding quality, superior sealing performance and reduced leakage compared to other vegetarian systems.
