Tocopherol (Vitamin E)

This is the natural form of vitamin E, an antioxidant that serves as a scavenger for free radicals that are destructive to the cell membrane. Vitamin E is considered the primary, lipid-soluble antioxidant utilized by skin that is present in the lipophilic portion of the cell membrane. Although alpha-D-tocopherol is the most widespread vitamin E, other tocols are also vitamin E, in the sense that they have vitamin E activity. The only difference between tocotrienols and tocopherol is that tocotrienols have three double bonds in their side chain and have a higher antioxidant activity.
