I went to my ND this week and I am not testing for mercury anymore, but for aluminum now. It must be because of Gerson and the Lugol's protocol, (iodine).

Here is more research on iodine.
Iodine sufficiency was associated with a sense of overall wellbeing, lifting of a brain fog, feeling warmer in cold environments, increased energy, needing less sleep, achieving more in less time, experiencing regular bowel movements and improved skin complexion. In some subjects with overweight or obesity, orthoiodosupplementation resulted in weight loss, decreased percent body fat and increased muscle mass. Following orthoiodosupplementation, increased urinary excretion of the goitrogens fluoride and bromide and the toxic metals mercury, lead, cadium and aluminum was observed; marked improvement of fibrocystic disease of the breast occurred following 3 months of iodine supplementation at 50 mg/day. In 3 patients with Polycystic Ovary Syndrome with olygomeuorrhea, orthoiodosupplementation resulted in regularization of the menstrual cycle. In patients on thyroid hormones, orthoiodosupplementation resulted in a decreased requirement to much lower levels of thyroxine and in some cases, resulted in the complete discontinuation of this hormone. This decreased requirement for thyroid hormones following orthoiodosupplementation was observed in a female patient with total thyroidectomy, suggesting that iodine not only improves thyroid function but also has an effect at the target organ level. In diabetic patients on insulin, orthoiodosupplementation resulted in better control of this condition, and in some cases alleviated this condition without the need for insulin. In hypertensive patients, whole body iodine sufficiency resulted in normalization of blood pressure without medications.
