Grizz,
Our beneficial flora is the majority of our immune system that resides in our gut. The beneficial acids that the flora produces has much more impact on candida than Iodine has. The major factor of candida is gut dysbiosis/imbalance(good flora deficiency), not a Iodine deficiency. The role of Iodine can not displace the trillions of flora that reside in our gut. The beneficial flora does not use iodine as its big gun but uses certain acids that keep candida under control. The big gun is the trillions of good flora that reside in our gut.
