The Minimum Riboflavin Requirement of the Infant

Abstract

An intake of 0.4 mg of riboflavin per day by the infant served to maintain adequate blood levels, to maintain the urinary excretion at the upper limit of the zone of minimum excretion, and was not associated with clinical evidences of deficiency. The limitations of these studies and the relation of the above figure to the minimum riboflavin requirements of the infant are discussed.
