I don't think ALA feeds yeast. When hg is being moved yeast problems increase. It is not the chelating agent that causes candida it is the heavy metals.

Cutler says this:

Yeast is actually a brain related problem (it is controlled by
inadequate hormone levels, especially hydrocortisone) and while it
improves with body detox, it doesn't go away until the brain is
cleared if it is a real bad case.

If you are really toxic DMSA is will not cure you and if you don't use ALA lifelong problems are to be expected. Cutler writes about this in AI.

Not only yeast but also endocrine problems and psychiatric stuff/neuro stuff.

What are your problems?
