Interrelationship between vitamins E and A: a clinical study.
Plasma vitamin A and vitamin E levels were determined in 45 children. Seven normal children and 7 children with vitamin A deficiency were given daily supplements of 100 mg vitamin E for two weeks. Seven others received a placebo and served as controls. The mean levels of plasma vitamin E and A were 694 microgram/dl and 21 microgram/dl respectively. There was no correlation between plasma levels of the two vitamins. Administration of vitamin E resulted in a significant increase in plasma vitamin A concentration both in normal children and in those with vitamin A deficiency, while there was no change in the control group.
