Nascent Iodine sometimes known by the generic term atomic iodine or generic trademark name Atomidine or by the misname detoxified iodine, is a liquid orally administered supplemental form of iodine, claimed to be in the monatomic state, originating from a 1931 Edgar Cayce formula. There is no evidence that "Nascent Iodine" is in any way distinct or superior to tincture of iodine. The promotion of "Nascent Iodine" is a form of quackery.
In 1929 the FDA Bureau of Chemistry stated on Atomidine advertised health claims "As far as our records go, all of these claims are without a scintilla of printed scientific evidence to substantiate the claim that Atomidine is superior or even the equal to tincture of iodine...".
