Sean, I was actually surprised that you are taking such a low dosage of DMSA. But your explanation about cost explains it. If anything DMSA, taken properly, is practically harmless and there is a large window of toleration so your body can handle more than you think. It is a lot easier to take than ALA. The brand that you take is expensive. That is why I use DMSA synergy which is a Canadian product. If you buy the large bottle 340 caps, it is somewhere in the range of $240. Now, this is much more affordable than the brand that you take, but DMSA, no matter what brand, is not a cheap item. So, I guess on a different level, I am in the same boat as you are. If it was not so expensive, I'd probably be taking 200mg per dose. But I remember Cutler posting somewhere that he did 100mg of DMSA and 100mg of ALA during his chelation rounds.
