I did some searching on silicon in the body. I found a book published in '85, "Silicon Biochemistry". (The chemistry in this book is mostly beyond me.) I also found some information in a National Academies Press online book .
And I did a search on pubmed and found some papers.
Apparently it is now thought that silicon might play a role in optimal cartilage and bone development and some other areas. The mechanisms for this have not been worked out. No dietary requirement has been set. The role of silicon at this time is unclear. There is silicon in many foods and beverages. The normal daily intake from diet is 20-40 mg Si. Raisins have 8 mg Si/100g. Bananas have about 5 mg silicon/100g. Cooked green beans and whole wheat bread have 2 mg Si/100g.
A common vitamin/mineral supplement contains 2 mg of silicon dioxide per daily dose - this is a form of silicon with a low solubility at body pH.
There's an abstract on pubmed about the absorption and excretion of silicon in beer. Beer has about 18 mg/liter, in the apparently more bioavailable silicic acid form. In the interests of science, the researchers tested *76* different kinds of beer on healthy volunteers.
The tissue salt version of silicon, Silicea, has about .5 mg Si per gram of tissue salt in the 3x version, and .5 micrograms Si per gram in the 6X version. It is in the silicon dioxide form. A 100 mg tablet of 6X Silicea would contain .05 micrograms Si. So while there may be some undefined value for silicon in the diet, the amount of silicon in the tissue salts is small compared to the amount in diet or in conventional supplements.
