There's not much science about Indium. Most of the evidence is anecdotal, and there's not very much of that. If you got to have proof, don't take it.
Indium was first tested in 200 mice compared to 200 controls by Dartmouth Medical School's Dr. Henry A. Schroeder, J.J. Balassa, Marian Mitchner, M. Kanisawa, A.P. Nason, and W.H. Vinton in 1964-68; who reported that INDIUM improved average Mineral absorption in the glands 142%; raised Chromium in all organs average 333%, enhancing Insulin that regulates muscle-building Protein and Carbohydrate energy in mammals.
http://www.indiumease.net/info.htmThe term indium, as used hereafter, means elemental indium and its FDA GRAS (Generally Accepted As Safe) compounds. The inventor is not aware of any scientific studies of the effect of indium, used as a nutritional supplement, on people. Indium always occurs in nature as a compound. The only indium compound presently on the FDA "GRAS" (Generally Accepted As Safe) list is indium sulfate.
A scientific study of the effect of indium on animals is an early work by Dr. Henry Schroeder, who is famous for his work on removing lead from gasoline. He studied seven trace elements and their toxic effect on mice (not humans); Schroeder et al, J.Nutrition, Vol. 101: 1431-1438 (1971); and Schroeder and Nason, J.Nutrition, "Interactions of Trace Metals in Mouse and Rat Tissues; Zinc, Chromium, Copper and Manganese With 13 Other Elements." He concluded that "Indium is not carcinogenic" and it is "relatively not toxic orally". (Schroeder and Mitchener at pages 1435,1436). There is no indication that Dr. Schroeder recognized any health benefits for mice, or for humans, from using indium as a nutritional supplement or that he used indium sulfate in his experiments on mice.
Indium sulfate is the only indium compound presently listed as Generally Recognized As Safe (GRAS list) by the FDA. The Index Medicus, MEDLINE (National Cancer Institute) indicates that the toxicity for rabbits (Lethal Dose Lowest--LDC, oral) was 1,300 mg/kg a day and rats 1,200 mg/kg. That dosage is about 20,000 times the usage (on a weight basis) of the nutritional supplement of the present invention. Indium appears in food substantially only as a complex trace contaminant which is not usable nutritionally.

In 2000 a double-blind study using indium was undertaken at the TCM Academy in Bad Ischl, Austria in collaboration with the Austrian Morbus Alzheimer Society. It involved 24 Alzheimer's patients, half were given indium plus a mixture of Chinese herbs while the other half were given the Chinese herbs alone.
After 30 days those taking indium showed an overall improvement in stamina and short-term memory by an average of 37 per cent compared to an 8 per cent improvement in the non-indium group.2
A larger follow-up study is now under way and HSI promises to keep you updated on the findings as soon as they become available.
http://www.thehealth...982/indium.htmlIndium appears to have no essential role in animal or human nutrition, although it is being touted as a dietary supplement. Those suggesting its value as a vitamin consider that indium, as a rare trace mineral, supports several hormonal systems in the body (Harvest Moon Health Foods, undated). They further suggest that anhydrous indium sulphate may “strongly elevate immune activity and reduce the severity and duration of a myriad of human ailments” (Vital Nutrients, 2002).
