Hello, I have MCS and I had an overgrowth of yeast. The last test showed the overgrowth of yeast is gone. I natural doctor told me that yeast leave behind mycotoxins that the body has a hard time getting rid of and that many people who take the following supplements for 4 months get rid of or greatly reduce their chemical sensitivities. The supplements are: Molybdenum, Pantethine, Lactobacillus Sporogenes, Fish Oil, and Black Currant Oil (for the high GLA). Have you tried these supplements by any chance?
