Sure, everyone has to decide on their own.

Of those links you just listed, the first post was mentioning that DMSA was causing low neutrophils which is a serious condition if left to continue.

Additionally, someone mentioned DMPS causing kidney pain which is sort of funny because that's one of the prime complaints of DMSA and I've experienced it myself.

As far as DMPS not being FDA approved- the FDA approved amalgams...need we say more?

From what I've read, DMPS is out of patent so there is no money for someone to put a generic drug through approval for millions of dollars. DMSA is ONLY approved for pediatric lead poisoning, not adults or mercury use- but of course people still use it. I've read plenty of clinical studies where it was used without any issues.

That's again why I say it's important to find a doc to monitor the process- it's important to know for example if your neutrophils drop or liver enzymes elevate.

I think there's a misconception that chelation should be painless and easy- but when you're drawing out huge amounts of a neurotoxin I think we should be thankful it can be done at all.

Many people on the frequent dose boards are looking for adrenal and thyroid meds but aren't even following the basics and taking antioxidants while they chelate! No wonder they feel terrible.

Cutler says of DMPS: "More often than not people find the subjective experience of using
DMPS more comfortable and pleasant. Also DMPS seems to stir up yeast problems less." http://onibasu.com/archives/am/92858.html

I think DMPS and DMSA both have considerable downsides but right now they're the best options we have and they have considerable studies on their use so we have a better idea of the their risks.
