When I first started taking kelp I had weird symptoms, a funny taste in my mouth and some other symptoms. I discovered on Dr Wilson's site that kelp helps detox chlorine and bromine. I was a swimmer and had these in my body. The symptoms didn't last long, maybe a month at most. The kelp absolutely has helped me tremendously! Stay with it. The Iodine is good for your thyroid and the micronutrients are good for you too. I use Nature's Way brand as suggested by Dr. Wilson.
