    You don't need to avoid iodine completely, but it is best to avoid large amounts where possible.  There are plenty of multi-vitamins available on the market which don't contain iodine, and it's also easy to get non iodised salt, so these will be better options for you.

    Hope this helps!

    You can have Hashimoto's disease and Graves' disease or hyperthyroidism at the same time. One can swing back and forth between hypo and hyperthyroid conditions. It is often one of the most difficult conditions to diagnose because if a doctor sees you during a hyperthyroid phase, you may be given antithyroid drugs or rushed into radiation treatment, which then deactivates the thyroid and worsens the existing Hashimoto's disease, whereas if you're seen during a hypothyroid phase, you may be given thyroid replacement drugs, which then make you more hyperthyroid.
    Iodine is a very controversial subject for thyroid patients because both too much and too little can be a host for a variety of thyroid problems. If you have autoimmune thyroid tendencies, taking iodine or an iodine-containing supplement, may in fact aggravate your autoimmune condition and worsen both Hashimoto's and/or Graves' disease and can make you either more hypo or hyperthyroid. If you are iodine deficient, however, then you can develop what's known as a goitre or an enlarged thyroid, and the use of iodine or iodine supplements can actually help restore your thyroid to normal functions. Deficiency in iodine is a major problem in the developing world, and areas where salt in foods are not routinely iodized. However, the lack of iodine has not been a common problem in countries where there is iodized salt. However, in people on low-salt diets and avoiding salty foods, we're seeing an increasing insurgence of iodine deficiency – but again, it's the minority of the population.Be careful of the yse of almost knee-jerk reaction and suggest kelp or iodine as a treatment. Unfortunately the reality is that whether or not you need iodine is a question unique to your own nutritional status, be careful to discuss it with your practioner before changing iodine intake..

    Hi Arlene thank you for your reply, I ended up having to have my thyroid removed and had a total thyroidectomy last week, I apparently had inconslusive nodules and an enlarge thyroid and goite, I had been taking the multivitamin for over a year now it was because a friend mentioned to me about taking it that I wondered if it caused any issues. so interesting the idone must not of helped ? but I am one of those people that don't use salt much but I also was very sick last year with IBD to the point of no return, and and I lost a lot of weioght nutrients and proteins in my body and hospitalised so now am courious if this also contributed to my thyroid problems.   I notice you are a registered dietition as I am looking for a dietition to help with a few medical problems that I have.  where abouts in the eastern suburbs are you? I work in sydney CBD?
