NCT00114387

Brief Summary

The purpose of this study is to examine whether vitamin E (DL-alpha-tocopherol) supplementation will reduce the progression of early atherosclerosis in healthy individuals over 40 years of age with low-density lipoprotein (LDL) cholesterol levels greater than or equal to 130mg/dL.
