Abstract

In order to know the limit of the amount of riboflavin absorption when intestinally administered, 5,10,20,40 and 80 mg of riboflavin respectively were given to healthy persons. The total amount of riboflavin excreted per day in their urine and feces was examined. Riboflavin absorption rate of up to 40 mg was more than 95 per cent, but that of 80 mg was 83 per cent. This indicates that the limit of absorption in the intestine might be between 40 and 80 mg.
