Yes, thank you. Don't worry, you are not offending me. I am speaking from years of health experience obtained through both myself and others.
Iodine can indeed be harmful if you have an existing thyroid problem. However, it can also help. It will only help if you have a pure form of iodine. The toxins have to be removed. This is why "detoxified iodine" should be used. In addition, when you only place one drop in a glass of water that is a pretty safe dosage.
Still, you should always consult a medical professional (preferably your doctor) before doing any kind of treatment. Your doctor knows you and what you are on. If you add anything they will know how it will effect everything else you are doing.
Therefore, before doing anything you read online, check with someone who knows and understands your specific condition.
When it comes down to it- a lot is unknown about thyroid function and dysfunction for that matter. It’s hard to determine what is truly helpful and what’s is harmful ... research in general is often limited to big pharmaceutical companies and supportive drugs rather than curative. It’s a shame.
