Lugol's is the liquid form of Iodoral. Both contain a combination of iodiNe and iodiDe. Both attach to human cells, some cells preferring one or the other. Both belong to the class of compounds called "halogens." Other halogens are: chlorine, bromine, and fluorine. Halogens are powerful germ killers. Chlorine is put into city water and swimming pools in order to keep down the levels of critters. Iodine naturally does the same thing in the ocean. This is why sea creature can survive in what is basically a large toilet. When mankind lived near the ocean, iodine deficiency was uncommon. Today, it is very common. When we saturate our bodies with iodine/iodide, it allows us to keep critter levels down, as iodine does for the ocean and chlorine does for a public swimming pool. Lugol's makes it easier to confer the protection of these halogens to people who can't swallow pills. 2 drops of Lugol's is equivalent to 1 tablet of Iodoral. Adults should start with 6 drops, children 3.
Consult your health care professional if you use either of these for infections or overgrowths. Halogens are very powerful yeast killers. Keep Lugol's/Iodoral out of reach of children.
