If your blood levels of mercury are high, which I do believe high doses of iodine would cause, ALA could redistribute mercury to the brain and other sensitive areas. ALA is only safe to use when blood levels are low. This is risky, and caution should be taken. Iodine is important, don't get me wrong, but redistribution is not something to take lightly.

If someone wanted to take higher doses of iodine while mercury poisoned I would reccomend they only take it while doing rounds with DMSA only. This would help excrete the mercury that iodine releases without risking redistribution .
