Vitamin a Stores of Sucklings Following Administration to the Dams of Vitamin a in Oily and Aqueous Media

Abstract
The vitamin A stores of suckling rats whose dams were given vitamin A in an aqueous dispersion were about 4 times as great as the stores of suckling rats whose dams received the same amount of vitamin A dissolved in oil. In view of previous studies on milk transfer, the conclusion may be drawn that orally ingested vitamin A in an aqueous dispersion is more effectively transferred to milk and stored in the suckling than vitamin A in an oily solution.
