Yes, I have some amalgam fillings and I don't have any symptoms or problems with mercury.

Most of the mercury ALA posts seem to revolve around the autism community. And I have seen papers going back to 40yrs from Europe that never bring this up as a risk.

The ALA doses are using the old racemic mixture, and those are quite high. Using the more efficient r-lipoic stabilized in 100mg a day is quite different IMO.

I would think that we'd see some damage if it were going to happen coming out of Japan. Japan uses lipoic acid heavily and is very touchy since the clioquinol (Vioform) B12 incident in the 70's and there are still law suits floating around from that one.

This Wiki article gives a good overview, and mentions, specific dosing for people using lipoic acid who have had amalgams removed only in reference to mercury. I would hope anyone undergoing this procedure would be seeing a holistic/integrative doctor for proper chelation. Typically succimer (chemet) is used in my area for this.
