Unless you have been eating a LOT of fish, & seaweed then you are quite simply deficient. Women especially suffer from deficiency, and the first symptoms to be noticed are cold hands, cold feet & menstrual/hormonal problems.
We live in a sea of toxins where bromide, fluoride & chlorine displace Iodine from our cells. Especially from our thyroid which causes low thyroid problems ( cold hands cold feet low metabolism) When you test your Iodine levels, also test for toxins.
I suggest starting with iodine capsules that are absorbed in the intestines, such as iodoral 12mg available at Amazon.Com.
You also need the co-supplements which are required to get iodine into your cells and the toxins out of your cells. '
Don't believe what you read or hear about iodine unless it is from a qualified iodine doctor. There is a LOT of mis-information out there. Expert iodine doctors include:
Abraham, Brownstein, Cousens, Flechas, Derry, Davis, & Tenpenny for honest & accurate information about iodine:

Surprisingly, the very best expectorant for the lungs is SSKI iodine. This runs circles around Mucinex, and was used by doctors extensively prior to WWII. 20 drops in a glass of water clears the lungs better than anything I have tried.

PS) When I first started this project, I was so deficient in iodine that the Lugols Spot Test disappeared in just 3 minutes. The iodine spot test is not accurate, but is worthwhile to see if you are severely deficient.
