Absorption & Bioavailability Enhancer

Antares Vitamin E TPGS demonstrates utility as an absorption & bioavailability enhancer of lipid and poorly soluble compounds especially in conditions of malabsorption by three major mechanisms:

  1. Emulsification of lipid compounds and solubilization of poorly soluble compounds
  2. Formation of micelles and micelle-like particles in oil in water emulsions that create a large total surface area of dispersed oil which facilitates absorption
  3. Modulation of efflux pump activity by inhibition of the P-glycoprotein (P-gp) which is It is responsible for decreased drug accumulation in multidrug-resistant cells and often mediates the development of resistance to anticancer drugs

The efficacy of vitamin E TPGS as an absorption & bioavailability enhancer has been demonstrated in cell culture, animal and major human clinical studies.
