Blood Tocopherol Values in Normal Human Adults and Incidence of Vitamin E Deficiency

Abstract

Summary

The mean tocopherol concentration in 197 factory workers in Rochester, N. Y., was 1.05 ± 0.32 mg/100 ml. About 7% of the subjects had less than 0.50 mg tocopherol/100 ml, the level below which red blood cell hemolysis tests become positive, indicating Vit. E deficiency.
