- Beta-Tocopherol: Another form of vitamin E that has antioxidant properties but is less prevalent than alpha-tocopherol.
- Gamma-Tocopherol: This form is also present in certain foods and contributes to the overall antioxidant activity of vitamin E.
- Delta-Tocopherol: Although less studied than the other forms, delta-tocopherol also plays a role in antioxidant defense.
