I would add in as much ascrobic acid/sodium ascorbate you can tolerate daily in multiple doses throughout the day as well. Vit C is a powerful antitoxin and can help with detox caused by iodine.
Its also essential for collagen based tissue(arteries, skin, cartilage, tendons etc). Ever wonder why life long smokers almost always look much older than they are? Smoking destroys vit C at an alarming rate depleting their skin of much needed collage building blocks. Same goes for heart disease.
