I personally used chlorella and protein powder containing the amino acid cysteine (which contains sulfur). This was before I knew anything about detox 12 years ago.

The problem with a "free sulfur" detox is that some of the mercury will be released while it is being transported to the liver, and more mercury will be reabsorbed in the colon.

DMSA clears mercury via the kidneys which prevent the reabsorption issue in the colon and it holds on to mercury more tightly.

Nevertheless, the natural way to detox mercury is using sulfur compounds, like chlorella, etc.
