Natural vitamin E compositions with superior antioxidant potency
Compositions for increased antioxidant potency of natural vitamin E (d-alpha-tocopherol), comprising alpha-, beta-, delta-, and gamma-forms of tocopherols and tocotrienols are disclosed. All of these compositions provide 400 International Units (IU), based on one mg of d-alpha-tocopherol provides 1.49 IU. These compositions showed antioxidant activities superior to natural d-alpha-tocopherol. These compositions are designed to provide protection of the cell membrane lipid layer, and protection against heart disease, cancer, and eye disease.
1. A composition of natural vitamin E with enhanced antioxidant activity, comprising:
(a) 55 to 85% by weight of d-alpha-tocopherol;
(b) 10 to 40% by weight of mixed tocopherols; and
(c) 2 to 3% by weight of tocotrienols.
2. The composition of claim 1 , wherein said mixed tocopherols comprise 70% tocopherols in the amounts of 5 to 15% aipha-tocopherol, 1 to 3% beta-tocopherols, 30 to 50% gamma-tocopherol, and 10 to 20% delta-tocopherol.
3. The composition of claim 1 , wherein said mixed tocopherols comprise 90% tocopherols in the amounts of 10 to 20% alpha-tocopherol, 2 to 4% beta-tocopherol, 50 to 80% gamma-tocopherol, and 10 to 20% delta-tocopherol.
4. The composition of claim 1 , wherein said tocotrienols are obtained from rice oil and said tocotrienols contain 10 to 15% aipha-tocopherol, 10 to 12% alpha-tocotrienol, 10 to 12% gamma-tocotrienol, and 2 to 10% other tocopherols and tocotrienols.
5. The composition of claim 1 , wherein said tocotrienols are obtained from palm oil and said tocotrienols contain 8 to 14% aipha-tocopherol, 8 to 14% alpha-tocotrienol, 15 to 30% gamma-tocotrienol, and 5 to 10% delta-tocotrienol.
