I believe it is safe to do so, based on my own experience with taking it for years while I had 8
Amalgams in my mouth. Further, if there were a detriment to doing so, one might suppose that by now all bottles of ALA would contain a warning, advising against people with
Amalgams in their mouths from taking it.
The human body makes its own lipoic acid; this is why it is not considered a vitamin. But, it makes only the R-isomer.
Importantly, most laypeople fail to realize that so-called "alpha lipoic acid" on the market is comprised of 50% by weight of the wholly-synthetic, non-naturally occurring S-isomer. Even the experts, like the chemist Cutler's book, neglect to mention that commercial ALA is 50% synthetic, less effective than the pure isomer, and possibly detrimental.
What many fail to understand also, is that nature's best chelator is IP6, or inositol hexaphospate, which is found in most, if not all grains. To say that one should not eat chelators while they have
Amalgams in their mouth is highly questionable, since it implies that no foods whihc contain IP6 should be eaten.
There is a wealth of knowledge out there on IP6, here is but one

As a chemist I recognize the value of IP6 as nature's most powerful chelating agent. I have serious doubts that people with amalgams in their mouth harm themselves by eating foods which contain IP6. By extension, same goes for other chelators as well.
Some argue that the reason against taking chelators with amalgams still in the mouth is that the chelator would pull mercury out of the fillings. I haven't seen any purporter of such opinions able to cite any references in support of their proposition, and view it accordingly as other baseless assertions.
The body is always chelating. I believe one must eat natural chelators (methionine found in many foods including sunflower seeds) in order for the body to work properly. I could make a long list of natural chelators, which would rule out y our entire diet if the premise that not eating chelators was desirable were to be believee.
