RELiZORB Hydrolyzes Fats Prior to Ingestion

RELiZORB is a digestive enzyme cartridge that contains iLipase® and connects in-line with enteral feeding systems. Lipase is covalently bound to small white beads inside the RELiZORB cartridge and is retained in the cartridge during use by two filters. Enteral formula flows through, allowing for fats to be hydrolyzed and the immediate delivery of absorbable fatty acids and monoglycerides to the gastrointestinal (GI) tract.

iLipase is made up of the digestive enzyme lipase attached to small polymeric microbead carriers and is stored within the RELiZORB cartridge

RELiZORB is proven to hydrolyze available fats,* including medium-chain triglycerides (MCTs) and long-chain triglycerides (LCTs).1

  • LCTs are complex and contain essential fatty acids
  • Compared to MCTs, LCTs are harder to hydrolyze but provide ~10% more calories
  • RELiZORB is intended to provide continuous fat hydrolysis during enteral feeding
>90% fat hydrolysis* with RELiZORB - Freedman




*Greater than 90% of available fats hydrolyzed in most enteral formulas tested, including Nutren 1.5, Impact Peptide 1.5,
Peptamen 1.5, Peptamen AF, and Nutren 1.0. Percentage of fat hydrolysis is estimated based on label claim for content, calculated using 500 mL of formula with a pump rate of 120 mL/hr.
