Vitamin E is a fat-soluble vitamin and antioxidant. A popular component of several moisturizers and lotions, this vitamin fights against destructive molecules in the body known as Free Radicals.
The Recommended Daily Allowance (RDA) for normal healthy women is about 15 mg, and about 19 mg for lactating women. Although some patients with heart disease have been known to take quantities of up to 4,000 International Units (I.U.) of Vitamin E, there is no real set dosage beyond the (RDA). A popular dosage is 400 I.U.
There have been recent studies that indicate that taking too much Vitamin E may be harmful, so as with any supplement, it is encouraged to speak to a physician before taking or deciding on a proper dosage.
