New 5 US Gallons (640 Fl Oz) of MediDINE true nascent Iodine in unopened factory sealed BPA-free plastic carboy. MediDINE 60 ppm (0.006%) of true nascent iodine is 100% bio-available, 99.9+% pure monatomic Nascent Iodine (non-ionic) colloidally suspended in pure pharmaceutical grade water manufactured and bottled in Nutraneering’s FDA registered facility in Irvine, CA; no color is added. MediDINE is unparalleled in its ability to potentially help, support, and saturate the thyroid with Iodine for optimal functioning. MediDINE is not typical toxic Iodine found in its denser state as an antiseptic, added to Potassium Iodide (a salt of Potassium and ionic Iodide, not elemental Iodine), or found in Iodine trichloride (chlorine suppresses the thyroid and is found in our tap water). MediDINE is also unlike prescriptions containing hormones that are meant to do some of the job of the thyroid instead of giving the thyroid the nutrition it needs to build itself up and function properly. Dietary sources of Iodine may not have the levels of Iodine needed by a malfunctioning thyroid, but a single dose of MediDINE has 501% of the FDA established RDA for Iodine.
