Vitamin E is a powerful antioxidant and is therefore one of the body's frontline warriors against the detrimental activity of free radicals via oxidation. So in essence Vitamin E
protects the cells within our bodies by preventing free radicals from setting off a chain reaction of lipid destruction. You see, the fat component of the cell membrane is especially vulnerable to damage from free radical oxidation (remember oxidation is destructive to our bodies and cells). That's where Vitamin E comes into play. Beyond maintaining the integrity of the cell membrane Vitamin E also protects the fats found in low density lipoproteins (LDLs). Lipoproteins are particles composed of both lipids and proteins and have the ability to transport fats through the bloodstream.
