I don't have intense Body Odor but I did have an interesting experience with Iodine- after taking it for a few days i DEVELOPED a strong Body Odor which I took to mean as my body fighting off old infections, perhaps in the lymph system. It may also have been bromine detox which Iodine alone can remove from the body (bromine comes from bromos or stench in greek) It was bizarre. What finally ended it was, ironically, rubbing Iodine under my armpits killing whatever bacteria was there.
Just food for thought if you think it may be some infection living in you.
