Abstract

The purpose of this study was to evaluate 2% agar gel diets as a delivery system for light-sensitive vitamin A for growing rats. In one experiment the absorption of 3H-retinyl acetate from agar gel was determined to be at least as efficient as from corn oil. In a second experiment, partially vitamin A-depleted rats showed improved growth rate and increased serum and liver vitamin A concentrations when fed the RDA for vitamin A in gel diet for two weeks. It is concluded that the agar gel diet provides an excellent non-stressful vehicle for administration of small doses of vitamin A in rats.
