Iodine is a key nutrient for thyroid function, and is recommended for radiation toxicity.
Note: I have recently started using Thyrodine, and have been blown away by its effectiveness for me. It has really kicked my thyroid into gear. Feel free to contact me for details.
The instructions on the bottle of Energique‘s Thyrodine say to add one drop to four ounces of water, and take internally, once daily. However, I’ve found that massaging it topically into the throat, over the whole thyroid gland area, one drop at a time, works much better. Making sure to cover the whole throat, I apply up to six drops per day. I normally do this in the morning. Note: I am a fairly large person, so my tolerance for Thyrodine is likely greater than that of the average person. If you choose to try the topical application, start with one or two drops, and increase over time to your optimal dosage.
