Wow..I don't know, but I might start asking a few people that would actually tell me. Most of them want the info. on the Iodine for themselves, and all are sent here! My cousin said she was very excited to come visit here and look into Iodine.
I don't think the Iodine smells, just if you have B.O. from detoxing from taking Iodine, and that could come from various places of your body, including mouth, teeth, etc. Not just sweat and or underarms.
I noticed I smelled B.O. on me from my underarms for a couple days since I upped my Iodine intake to 120 mgs..but not now. I checked after a whole day of strenuous gardening yesterday, and I didn't smell anything except me..and I smell nice..naturally scented.
