Guest guest Posted June 29, 2009 Report Share Posted June 29, 2009 The commonly used amalgams these days have the following content on average (note that zinc is less than 1% of the total metal, and the average filling is 1/2 gram. Since zinc isn't toxic except at extremely high levels and you aren't likely to get high levels from amalgam, I don't see how amalgams could be much of an issue regarding zinc. Multivits have much higher daily doses than you could possible get from amalgams. ************ Around 1970, the ingredients changed to the new non-gamma-2 form, with lower manufacturing cost, greater mechanical strength, and better corrosion resistance. The reduced-gamma-2 amalgams (sometimes referred to as " high-copper " amalgams) contain approximately equal parts 50% of liquid mercury and 50% of an alloy powder containing: [ citation needed ] • > 40% silver (Ag) • < 32% tin (Sn) • < 30% copper (Cu) • < 2% zinc (Zn) • < 3% mercury (Hg) ******************** Zinc is not what to worry about re: amalgams. Worry about the highly toxic mercury which is over 50% of the amalgam and is lost daily at high levels (30 micrograms/day on average for someone with several fillings) (mercury gov't standard is 2 parts per billion) (these levels are extremely higher) (mercury losses are high because mercury is a gas at room temperature and vaporizes continuously, not so for zinc). High levels of mercury vapor in the mouth and lungs of someone with amalgams at all times, but not the other metals. The other metals are just lost primarily by galvanism, but more slowly. Copper is also something to worry about here, and tin, since organotin complexes are extremly toxic. Quote Link to comment Share on other sites More sharing options...
