Thank you for the information. I am allergic to DMSA and in the past I could not eat garlic or onions for years. I began to reintroduce cooked onions and some garlic a few years back but after just touching on capsule of DMSA when being muscle tested by my chiropractor I experienced immediate sulfur taste in my mouth, my jaws tightened, and popped, agitation, confusion, wiredness, and my muscles were sore......deeply sore for FOUR days afterwards, therefore I cannot chelate post Amalgam removal with DMSA.
