The purpose of the present investigation was to determine the nutritional status with respect to vitamin B1 of persons suffering from toxic and nontoxic thyroid disease. The consistent rise in the pyruvic acid of the blood in vitamin B1 deficiency provides a quantitative method of estimating the extent of this deficiency.
