Abstract

These experiments show that the pigmentation-suppressing factor in fish-liver oils is vitamin A. Carotene fed at comparable levels does not exert a suppressing effect on pigmentation. Inhibition of pigmentation takes place when there is a sufficiently large bodily store of vitamin A; it is not exclusively an intestinal phenomenon.
