There seems to be a wide range of interpretation and use of the words like "chelate" and "detox", so I'll throw in my two cents - they are not one and the same.
Detoxing as I understand it, means taking measures to flush out whatever toxins are already loosely floating around in the body IE> already mobilized; "whatever" may be any from the range of toxins we all are commonly exposed to by polluted water, polluted food, polluted air and polluted medical treatment like dental fillings, vaccinations
and prescription drugs, to include mercury, cadmium, arsenic, and alluminium just to list some of the common pollutants. Flushing the liver, flushing the bowells, and flushing the kidney/bladder will help to expel IE> detox, these freely-floating toxins from the body.
Chelation, on the other hand, is taking the situation to the next level, so to speak, with measures to draw toxins out of their hiding places within the body, such as within tissues, within cell-structure, within bone, teeth, and organs like brain, lungs, heart, kidney, liver, etc. In other words, aside from those toxins freely floating around in the body, there are also toxins that may have once been freely floating around but eventually found places to hide - becmong tightly embedded into the fabric - literally, of our body. This is the opposite situation from those toxins loosly floating around in the body. The process of chelation is two-fold: mobilization; binding. The former stirs things up so to speak, in an effort to shake loose these tightly bound toxins from their hiding places, the latter provides an ingredient to latch onto them before they can find another hiding place to settle. Once the binding agent binds to a loosley floating molecule of toxin, then it is a matter of the body properly disposing of it, via the various disposal system like intestines, lymph, urnine, sweating and breathing (exhaling).
The best I can tell, while one still has Amalgams
in their mouth, it is not time to chelate because these remaining amalgams, even one, represent such a massive amount of mercury that the attempt to chelate will stir up more free mercury than what can practically be bound and excreted, so this will leave a lot of mercury freely floating around to become redistributed to some other hidign place. The idea on waiting to chelate is another way of sayign "don't shake things up yet and move the mercury to some other places, leave it where it is, wherever that may be, for now. Meantime, it's okay to detox, such as with flushing, and with increasing one's daily intake of those vitamins/supplements/nutrients that are good scavengers of free radicals. The general idea is that detoxing is to revitalize the natural detoxing ability of the various internal systems of the body that go on (or try to) 24/7. This is also the time to begin improving one's daily water intake; this aspect can't be over stressed since intake of water is simple and easy way to help the body flush itself. The kinds of Flushing often referred to in these forum posts is intended a sa method for mass-dumping (detoxing) toxins from the body on a much larger scale than the natural flushign from good water intake. There are also steps one can take to provide beneficial mini-dumping effects; taking specific vitamins and supplements, or taking hot soaking baths. Vitamin C has numerous benefits, to include a detoxing aspect. I believe the fact that I've been followign Pauling's daily mega-dose regimen for nearly twenty years is a big reason why I otherwise have not already experienced more significant effects from having carried around 14 amalams in my head for 30-plus years. My dentist advised me to also add Selenium supplementation, especially for those days after having a quadrant of Amalgams
removed; it's what he takes each day that he's spent bending over a person taking out their fillings (and having their vapors drift into the air he breathes).
Once all the amalgams have been removed, then it's time to kick it up a notch with one's detoxing efforts. If you've done your homework and prepared the body well for this step - like by having done various flushes while the amalgams were still beign taken out, improved your diet, generally taking better care of yourself, then you've definitely improved your general condition of health, which means you've given yourself a better chance to suceed with the chelation stage. I'm still learning but from what I can tell, chelation is not a quick process, it may/could take years to gradually shake loose all the very deeply embedded of toxins on one's body, especially mercury.
Good subject, but not necessarily a simple one and therefore not one to be taken casually.
Good luck and best wishes!
