Iodine definciency is a major problem for these kids. Understanding halogens and how cholrine, fluoride and bromide replace iodine in halogen receptors in the glands of the body is important, cutting the 3 bad boys our of life and replacing them with iodine is proving to be beneficial in autism. I have to keep my conscience clear and state that I would NEVER give my child Lugol's iodine. MH has started a strong plant based iodine suppliment that I will be taking then if I find it perfectly safe, giving to my adhd grandson.
