As far as Lugol's it gets reduced pretty readily in the body so it isn't as good at killing systemic fungus as it is for killing fungus on contact. So we need to get it to contact as much as possible. Dilute some in water, add a bit of Sea Salt , and snort it if you want to clear the sinus and nasopharanx. Add some to your scalp. Vitamin c liquid will reverse skin staining so you look normal again lol.
But 15 drops of 5% isn't that much. Thats around 100mg, I have taken at least 5x that much. But high dose Iodine you need to be taking a good amount of selenium to prevent thyroid issues from oxidation. This takes time to happen so 1 day of 100mg it doesn't suprise me you don't notice much.
But really you want to boosting all detox pathways to turn the tide on candida. My restitution product is a good example of a product that does that and its open source.
ps I agree with the above poster. If you want todo dmsa it needs to be with diatomaceous earth to prevent crazy gut microbe issues. A product like the above restitution product will do what you are looking for all naturally as opposed to the unnatural dmsa
