While whole grain foods are a good natural source of Silicon (Si). The Si from these foods is insoluble and cannot be directly absorbed in the gut.
Si in these food is solubilized by stomach acid into orthosilicic acid, which absorbs directly through the stomach wall and the intestine into the blood.
Lower stomach acidity, whether due to illness or age, diminishes our ability to metabolize Si from these food sources. Aging is reported to be associated with an increasing gastric pH. In this view elderly people will have a decreased capacity to convert dietary silicates into bioavailable Silicon.
Modern day refining and processing of food has also led to much of the Si-containing fibers being removed.
The best bioavailable, bioactive Si which is readily absorbed by the body.
Spritzer natural mineral water is one of the best source of rich bioactive, bioavailable, absorbable Si for your health.
