Candida is an opportunistic disease that takes over when the immune system is in shambles. Iodine (Also D3) substantially boosts our immune system so that it can kill fungus on its own without help from drugs.
As I have been saying all along, we should focus on curing our immune system instead of treating symptoms with drugs. Just imagine futility of attempting to treat each of those D3 symptoms individually.
Bottom line: Cure the immune system cures a Pandora's box of disease, including Candida.
