OSA and its salt, sodium silicate, are not silica (SiO2 silicon dioxide). Dissolved in water, OSA and sodium silicate can’t be converted to silica and silica is not converted to OSA in the human body. Therefore, the toxicology of silica does not apply to OSA or its salt, sodium silicate.
It is safe to drink bottled OSA rich water and beer. For a list of waters and beers see appendices I and II. It is also safe to drink handcrafted Silicade made by neutralizing a sodium silicate produced by PQ Corporation and sold online that is 99.5% water soluble (see appendix III). This product is sold by PQ Corporation directly and distributed through Brenntag to many U.S. community water departments that add it to public drinking water. In addition to being a brain saver, OSA provides corrosion protection. This PQ Corporation product meets the ANSI standard specification set by the American Water Works Association (AWWA) for silicates added to drinking water, as it contains only a 0.5% water insoluble impurity222.
OSA is commonly found in rivers, lakes, aquifers, and drinking waters around the world140. Dissolved OSA from soluble silicates added to drinking water in the U.S. is identical to dissolved OSA in beer and mineral waters140,232. The amount of OSA in drinking water varies widely depending upon the source140. In the U.S. 160ppm of dissolved silicates as OSA are generally recognized as safe (i.e., GRAS) in drinking water by the FDA221. The adequate intake of water per day is 3 liters for men and 2.3 liters for women. This level of water intake corresponds to a maximum safe level of OSA intake per day of 480mg for men and 368mg for women. Therefore, drinking 4 cups (approximately 1 liter) of OSA rich water each day containing 50 to 150mg per liter of OSA is well below the GRAS level for dissolved silicates.
It is safe to ingest dissolved silicates, such as OSA, at concentrations well below the saturation level (i.e., less than 200ppm of OSA) in order to ensure that they will not become supersaturated and crystallize in the kidney lumen. Ingesting OSA above the saturation level (i.e., 200ppm) can result in kidney stones (a.k.a. nephrolithiasis) in dogs but almost never in humans. There is one report of kidney stones resulting from too much silicate salt, erroneously labeled as silica (SiO2), used as an inactive ingredient (a.k.a. excipient) in several over-the-counter drugs such as Uncaria Tomentosa, Digestive Advantage, and FlexProtein supplements507.
