"Every enzyme molecule requires a particular metal to function correctly,"
"However, certain metals, like gold"
"...will replace those NEEDED metals."
White gold is NOT metal. That's the point made over and over with ORMUS. Gold (and other elements) in their monoatomic form (ie. not clumped with other fellow gold, silver, plat, etc. atoms) manifests in a pure elemental NON-METALLIC form. Because it's not a metal, it behaves MUCH differently in the body.
In fact, most human and animal brains are found to have approximately 5% monoatomic elements by weight. That stuff was meant to be in our brains, and the more there is, the better we seem to function.
I can't and won't force you to look at this. However, if you can bring yourself to momentarily put aside your bias and look at what people have reported and discovered about this stuff, it may bring you to a new understanding. Your choice, but the point remains that the concerns you raise - valid though they may be - only apply to the METALLIC form of gold, not the powdered, elemental form, which exhibits COMPLETELY DIFFERENT properties, in and out of the body.
