Enters the bloodstream and is transported to the organs of the reticuloendothelial system (liver, spleen, bone marrow) where it becomes part of iron stores.
Therapeutic Effect(s):
Resolution of iron deficiency anemia.

Distribution: Unknown.
Metabolism and Excretion: Maltol is metabolized in liver via glucuronidation by UGT1A6 and via sulfation. Maltol is primarily excreted in urine as glucuronide metabolite.
