I am convinced that many of the symptoms are due to mineral deficiencies. Many who are mercury toxic don't produce enough stomach acid, and have impaired mineral absorption. Chelation also causes loss of minerals, particularly zinc and copper, but also iron and manganese. Most people in general are magnesium deficient, but those who are mercury toxic are often even more deficient. Are you taking mineral supplements? Molybdenum supplements help greatly to reduce chemical sensitivity.
