Indium sulfate: industrial chemical, not dietary supplement
Indium sulfate is being marketed as the newest miracle dietary supplement. On the Web Elements Indium page, under biological information, the statement is made that "Indium has no biological role. In small doses it is said to stimulate the metabolism." but under hazards and risks, the statement "All indium compounds should be regarded as highly toxic. Indium compounds damage the heart, kidney and liver, and may be teratogenic." The second statement is consistent with the research I have done in the past few days. The first statement is consistent only with the highly suspect claims of the marketers. I strongly recommend that the statement that "it is said to stimulate the metabolism" be deleted from this page, as the only stimulation I have been able to find is that it makes membranes rigid by peroxidating them, and stimulates the cellular uptake of chromium, zinc, manganese and copper. Thank you.
