I had a meeting with a pharmasist today about bioidentical hormones and she said you can test yourself to see if you are deficient in iodine. Rub a circle of iodine tincture on your stomach and if your body absorbs it quikly you are deficient if it lasts all day and all night your good.
It was awsome to have her validate everything I have learned about thyroid issues and recommended a thyroid and armour friendly doctor :)
