the problem is i dont know for sure what they have so how can i know its safe?
dr Lugols learned how to dissolve elemental Iodine in water by adding potassium Iodide to the water first. any aqueous solution of Iodine is technically Lugols because it must employ KI to do so.
lugols can be seen as the ratio of salt to I2. the standard Lugols 5% strong Iodine solution is 10/5. SSKI 2% with magnets is 100/2. the newly coined 2% lugols is 4/2 and is simply lugols 5% watered down - 3 parts water to 2 parts lugols.
heaven only knows what the 7%, 10%, 15% and so on lugols are. you need the ratio of them as demonstrated above.
