On the Absorption of Vitamin D from the Skin

Abstract

When vitamin D, in the form of cholesterol, which had been irradiated with ultra-violet light, was rubbed into the skin of rabbits, fed on a rickets-producing diet, rickets was prevented. Support was thus given to the suggestion of Hess that activation of lanolin by sunlight, and its subsequent absorption through the skin, is a possible source of vitamin D for the body.
