Nutritional Availability of Iodine from Several Insoluble Iodine Compounds

Abstract
Iodine was found to be nutritionally available from insoluble cuprous iodide, diiododithymol, and 3-5-diiodosalicylic acid. Acute and chronic toxicity tests indicated that Cu2I2 and 3-5-diiodosalicylic acid were non-toxic in amounts required to protect the thyroid gland.
