Silicon Dioxide
		Silicon Dioxide function as an excipient keeps ingredients from getting too sticky, adds moisture and aids in the formation of tablets.  It is found in nature as quartz, and is a major ingredient in the   production of semiconductor chips, glass, ceramics & Portland Cement. Although this chemical is known to have extensive acute, subchronic and chronic toxicities in animal studies, silicon dioxide is considered an acceptable food additive by the FDA.   This is primarily because of a lack of understanding the difference between silica found in food, or mammalian tissues, and inorganic forms.  The qualitative difference is profound, and though the elemental silica content may be the same in a chard of glass and a piece of celery, the biological difference is as profound as the difference between life and death.
