Serum studies in man after administration of vitamin A acetate and vitamin A alcohol: I In normal subjects

Abstract
Absorption of vitamin A alcohol and acetate in normal subjects is discussed. There is no significant difference between serum level after administration of vitamin A alcohol and vitamin A acetate. The use of a fatty meal during the test is recommended. Exercise appears to affect the curve; it is important to keep subjects resting during the test. The use of 2 samples (at 3 and 5 hours) is more accurate in detecting peak serum absorption figures than 1 sample at 4 hours.
