A Possible Role of Iodinated Casein in Intestinal Assimilation of Vitamin B 12. ∗

Abstract

Summary

Dietary iodinated casein led in chicks given dietary vit. B₁₂ to higher cecal contents of vit. B₁₂ and in chicks not given dietary vit. B₁₂ to lower liver contents of vit. B₁₂ than those found in respective controls. It is suggested that the ability of iodinated casein to increase the sensitivity of chicks to dietary vit. B₁₂ is due in part to an interference with intestinal absorption of the vitamin.
