Abstract

Varying amounts (equivalent to 19.4-308mg vitamin A-alcohol) of synthetic vitamin A-acetate and-palmitate dissolved in vegetable oils were ingested and the amounts of the vitamin excreted in feces were estimated. The amounts ingested minus those excreted in feces were assumed to be the amounts absorbed from the intestine. It was found that about 90 per cent of the vitamin ingested was always absorbed from human intestine regardless of the amounts ingested. The reason for the difference of the results from those obtained in the previous experiment was discussed.
