Abstract
No significant change occured in urinary excretion of inorganic sulfate in children after a supplement of water-soluble vitamins, whereas addition of vitamin A, together with watersoluble vitamins, resulted in a marked decrease. In contrast to inorganic sulfate, the excretion of taurine was decreased remarkably by a supplementation of water-soluble vitamins and it came to more lower level by an administration of vitamin A. The decrease of taurine can be possibly explained by an assumption that a stress of hypovitaminosis had been imposed on the children and that the stress was lightened by dosing of the vitamins.
