HI Alison, you can chelate on ALA alone. You do not need DMSA or DMPS, they are optional. They are only used in the beginning to help reduce the blood/urine levels faster and more effectively than the person would do on their own.

ALA can be used, so long as it's 3 months after any mercury exposure, and not before.

ALA is necessary for chelation, DMSA etc are optional. You can use that and get well and be on the candida diet at the sametime.

Both should help.
