Abstract
The rate of absorption of vitamin A in rats was found to be proportional to the concentration of the administered material. The average absorption per 100 sq. cm. per hour was as follows: 4.2 to 6.5 I.U. for 100 unit material, 28.5 for 1,000 unit, 369 for 10,000, 2108 for 100,000, and 10140 for 1,000,000 unit. There is no relationship between the rate of absorption of neutral fat and vitamin A. Evidence is given which indicates that vitamin A is not destroyed by intestinal bacteria over a 3-hour period.Keywords
