SENDS™ - Self Emulsifying Nutraceutical Delivery System

Are you nutrients getting to their destination? Many supplements contain multiple ingredients that are aimed to target certain health benefits like bone health, daily vitamin intake, mental focus, increased energy. Supplement manufacturers choose the right ingredients based on the benefit but sometimes delivering those ingredients to the right place in the body and ensuring they are absorbed can be challenging. That's where ABITEC comes in!  ABITEC's products enhance solubility & promote emulsification of active nutraceutical ingredients (ANIs), leading to greater bioavailability. We even have a system for ensuring we SEND nutrients for absorption.

The SENDS Solution

ABITEC's Self-Emulsifying Nutraceutical Delivery System (SENDS) is a formulation method by which poorly water soluble compounds are able to be solubilized and subsequently absorbed. It provides extensive benefits for your formulations including:

  • Enhanced bioavailability
  • Increased formulation efficiency to reduce dose
  • Protection of ANI during processing or manufacturing and in the gastro-intestinal environment
  • Reduced food effect
  • Usable in liquid or solid dosage forms
  • Each SENDS is custom designed to meet your formulation needs

A typical SENDS system will consist of a solubilizer, an emulsifier, and a surfactant and/or co-surfactant. For the nutritional space, ABITEC supplies a portfolio to support SENDS formulations:

  • CAPTEX® - Solubilizers
  • CAPMUL® - Emulsifiers
  • ACCONON® Surfactants

These product families can be used alone as a neat solvent or together in the formulation of self-emulsifying systems to ensure your nutrients reach their destination and are properly absorbed by the body. In addition, a SENDS formulation can reduce the amount of ANI necessary, and thereby reduces the dosing cost of the ANI in the supplement.

CAPROL®

These polyglycerol esters (PGEs) are used as emulsifiers and solubilizers in an array of nutritional supplements because they offer a wide range of HLBs meeting the needs of many formulation requirements.

In addition, other benefits include:

  • Improves texture and consistency
  • Works well with proteins to improve flow properties
  • Addition of smooth mouth feel
  • Stabilizes aerated systems by controlling the agglomeration of fat globules
  • Reduces interfacial tension at oil-water boundaries
