Animal Nutrition Applications

Antares Vitamin E TPGS provides highly-absorbable, bioavailable, water-soluble, natural vitamin E that can easily replace other forms of vitamin E (that are not efficiently absorbed by animals) in animal feeds and supplements.   

Typical Uses in Animal Nutrition:

Fortification of animal feeds 

  • Premixes
  • Concentrates
  • High potency vitamin E
  • Nutrients and nutrient blends with enhanced absorption and bioavailability

Dosing formats 

  • Liquids
  • Powders
  • Gels
  • Tablets
  • Blocks


Formulating Advantages of Antares Vitamin E TPGS:

  • Melts at body temperature
  • Available in NF grade, Food Grade (FG) and non-GMO grade (SF)
  • Long history (over 50 years) of safe use
  • Versatile, functional ingredient with proven usefulness in formulating solid and liquid nutrient mixtures
  • Readily mixes with water
  • Readily forms emulsions of oil in water
  • Readily disperses onto powders
  • Can solubilize a wide range of oils and poorly-soluble nutrients
  • Supplies natural d-α-tocopherol in water-soluble form. (It is universally accepted that the natural form of vitamin E, d-α-tocopherol, is more potent than the synthetic form of vitamin E, dl-α-tocopherol. This body of acceptance extends throughout industry and includes the Food and Drug Administration (FDA) and the National Academy of Sciences (NAS)). 
  • Enhances the absorption and bioavailability of oil-soluble nutrients and natural compounds

Superior Source for Vitamin E Needs in Animals:

  • Zoo Animals, especially elephants and black rhinoceros in captivity have circulating levels of vitamin E indicating deficiency. Supplementation with synthetic dl-α-tocopheryl acetate, the traditional forms of vitamin E used in animal feeds and supplements, does not correct the deficiency. TPGS was shown to correct this serious deficiency by supplying highly absorbable natural d-α-tocopherol (see references 1, 2 and 3 below).
  • Horses, especially racing horses, have increased needs for vitamin E. TPGS was shown to rapidly increase the vitamin E blood levels of horses especially in comparison to the synthetic dl-α-tocopheryl acetate commonly used in feeds and supplements.
  • Pets and Other Animals that, due to genetic, age, and other conditions affecting their nutrient requirements, require highly absorbable and bioavailable vitamin E.
