Silicon ( Si(OH)4 )
Silicon (Si) is the predominant water soluble form that is bioavailable and absorbed by body.
Silicon (Si) in nature is rarely found in its elemental form but occurs chiefly as insoluble silicates and small amount are present as water soluble.
Around neutral pH, Silicon polymerizes at concentrations much above 2mM, forming a range of silica species from soluble dimers to colloids and solid phase silica and become less bioavailable to the body. Hence it is of utmost importance to verify that the Si existing in any product is truly Silicon ( Si(OH)4 ) the soluble, bioactive and bioavailable form. Spritzer natural mineral water Si content confirmed by University of London to be virtually 100% water soluble, bioactive Silicon.

Plants take up Silicon from the soil, which is transported through the plant in this form, and is then mostly deposited in cell lumina and walls as solid amorphous silica deposits known as phytoliths.
Therefore, in plants and plant-based foods, Si is present as insoluble phytolithic silica, but intestine up take proceeds following luminal hydrolysis to Silicon.
Food processing and refining removes Si as it strips the husks/fibre in which Si is largely present.
