Ginagirl, can you plz give me a link to what you call "RRR" threads. I want to know if I need iodine, I am 31years old but started to notice like swollen area on my right side of the neck :/ and I am always exhausted. I work out three times a week and weight 115lb. Eat healthy and still super fatigue so I want to do a little research before jumping into anything. I am taking chelated minerals which have helped me a lot. But i think I might be needing more then that.Thanks for the help.
