kelp and meds

Hello! I have been taking a teaspoon of powdered kelp on and off for the past year or so. I haven't taken it in quite a while but am wondering if I start using it again now that I'm on medication (50mcg of levothyroxine) is it going to cause problems?

I originally started using it because I began using noniodized sea salt and I don't eat many processed/packaged foods. I was concerned about becoming deficient in iodine (I don't feel I was or am iodine deficient but I don't want to move in that direction either).

Anyone have any experience with this? Any help would be appreciated!


Love and Prayers, Kelly

Re: kelp and meds

Kelp is not recommended for thyroid patients unless they are deficient in Iodine. Not many people in the US have an Iodine deficiency.

Excess Iodine can cause your thyroid to shut down and if it is already not working well give you more hypoT symptoms. The Iodine in kelp can also bind with any thyroid hormones that you take.

So taking kelp or eating lots of seaweed (or anything else with Iodine) is not a good idea for hypothyroid patients.

Re: kelp and meds

Thank you diatron for the info! I kind of figured it was a no no .

If I do become iodine deficient how will I know the difference between that and a need to adjust the meds?

Love and Prayers, Kelly

Re: kelp and meds

Diatron will probably have the right answer, but can I throw in my opinion?
The only purpose for iodine is to synthesize thyroid hormone within the thyroid gland. Iodine doesn't make you "feel" any better or worse.
If your gland can't make use of it anyway because of its malfunction, what difference does it make whether you ingest enough or not?
