Simple answer: d-alpha or the full spectrum of tocopherols and tocotrienols.
I recommend the Metagenics E Complex-1:1™. It is a pure, unesterified vitamin E formula that features d-alpha tocopherol combined with a mixed tocopherol blend, achieving a one-to-one ratio of alpha to gamma tocopherols. This unique formula is designed to provide the antioxidant benefits that come from consuming a comprehensive family of tocopherols.
- Vitamin E inhibits protein kinase C activity, which supports cellular health in several types, including smooth, muscle, platelets, and monocytes.*
- Delivers an especially powerful blend of different tocopherols for a broader range of antioxidant protection against the ravages of free radicals.*
- Provides balanced levels of gamma- and alpha-tocopherols that are more closely associated with consumption of vitamin E-rich foods.*
- Provides gamma-tocopherol for unique antioxidant protection.*
