"I would add a few drops of LugolsIodine to the water instead as you mention thyroid problems."
Everything in 'main stream', mordern medicine will tell you to stay as far away as possible from Iodine when you're dealing with hyperthyroidism.
Hypo is different.
But I'd sure never ever take the chance doing Iodine when being hyperthyroid.
Not so fast.
When iodine no longer binds to thyroid cell membranes enzymes called peroxidases are able to damage these membranes and produce autoimmune diseases such as Hashimoto’s thyroiditis and Hyperthroidism (Graves Disease). Researcher Dr. Guy Abraham has observed several cases of thyroiditis and hyperthyroidism that have been corrected by the simple replacement of iodine. For more than 100 years high doses of iodine have been known to benefit both underactivity (hypothyroidism) of the thyroid gland and overactivity of the thyroid gland (hyperthyroidism). Iodine therapy allows the sluggish thyroid gland to resume normal production of thyroid hormone leading to resolution of hypothyroidism. Provision of iodine stops the peroxidase injury to the thyroid membranes in hyperthyroidism which permits hyperthyroidism to resolve. Thus thyroid surgery for hyperthyroidism is no longer necessary
