Versatile plant-based alternative to gelatin


For more than a decade SeaGel® has been a leading plant-based softgel technology used by many brands globally for non-gelatin soft capsules containing a wide range of different nutrients such as algae oil, CoQ10, vitamins, and lutein.

Naturally derived from non-animal sources, our SeaGel® technology features superior versatility, robustness, best-in-class functionality and effectiveness second to none. It allows delivering a pure, superior quality product, time after time addressing consumer’s preferences and manufactured efficiently. SeaGel® soft capsules maintain structural integrity even under high temperatures, which allows encapsulation of challenging, higher viscosity formulations and which simplifies handling, storage and shipping to the consumers. 

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

  • Easy to adopt in existing gelatin operations
  • Allows manufacturers to utilize industry standard capsule die designs while other plant-based systems often require oversized capsule pockets to minimize internal pressures
  • Production rates and yields unmatched by alternative plant-based softgel technologies while still enabling best-in-class quality and sealing properties
  • Superior versatility in capsules size and shape due outstanding film strength and elasticity
  • Capsule fill weights above 90% of die pocket specifications even with challenging formulations
  • Superior sealing performance and reduced leakage unmatched by alternative, standard vegetarian systems
  • Addresses the needs of vegetarians and vegans who are opposed to ingesting animal-based gelatin soft capsules
  • Adapts to many capsule brand strategies, including different capsule colors, sizes, shapes and printing. 
  • Follows non-GMO, vegan, vegetarian, Halal, Kosher and ‘clean label’ designations.
  • Withstands high temperatures and humidity without risk of cross-linking or melting capsules.
