Everytime you exercise, you cause a redistribution of some of the mercury (or other toxins). They go into your circulation for a while, make you feel like garbage and then resettle again in other areas.

I am assuming you no longer have amalgams? if not, DMSA can help clear some of this mercury out and some find they are more tolerant of exercise whilse they're taking DMSA because it's there in the blood already grabbing some of the freed up mercury.

I'd advise taking it the way Andrew Cutler suggests, which is one pill, (e.g. 25 mg - 100 mg) every 4 hours around the clock (yep even at night, so you need to set an alarm). You do this non stop for about 3 days (or up to a week if you wish) and then break for the same amount of time you spent on it. And then do it again and repeat the same cycle till you start improving. This ensures that the DMSA remains at the same level in the blood stream and then can grab and remove mercury more consistantly and safely. If the DMSA is taken sporadically, it can actually CAUSE redistribution, because of the infrequent dosing. It must be taken every 4 hours, or the levels of DMSA drop too low after that point.

This can help. Algin is another product that can be of great benefit apparently. It is natural and the owner of this forum recommends this is one of the primary things to take for mercury poisoning. It can act as a sponge and can be taken whether you have amalgams or not.

Some find it helps them tremendously. Depends on how it works for you. Algin is not a chelator however, it will simply sponge up mercury in comes in contact with. i do not know how effective that would be with mercury in the blood, but DMSA is VERY effective with that side of it.

You may also find that if you ever have a hot bath, that you may feel horrible after that as well. When your blood stream is still high in mercury, bathing in hot water can sometimes encourage some of it to come out via the pores (as with exercise). So you can sometimes get a redistribution off that as well. But it can be a good thing to do to help eliminate some more mercury. It's just the side effects of anything that stirs mercury up that's unpleasant.

But DMSA will clear your blood of mercury. If you have amalgams, then I'd not advise chelation and algin might be the safer choice in that respect.

Though "Some" seem to do ok chelating with amalgams, generally it is not always recommended.
