I have Hashimoto's. Before my lyme dx, my ND diagnosed low thyroid function and had me paint iodine patches on myself as both a test and a treatment.

It was not enough, as all thyroid conditions are not caused by an iodine deficiency and therefore are not fixed by iodine supplementation. Kelp is used predominantly for the iodine, though of course it contains other nutrients.

I am but one data point, but based on the foregoing points I suspect that you'll need actual thyroid hormone supplementation.

I take Armour thyroid.

Good luck,

Some people do well with Armor Thyroid; while it blocked my autonomics and was therefore not a good idea. It works well for my husband. ART testing determines which.

I used Mountain States Health Products, Thyroid H, a homeopathic, which worked great
and kicks the immune system into gear.

The heavy metal detox is a priority. Mercury sits on the ligand sites of the hormone producing cells and nothing works well or normally until the stuff is out or the load lowered. It can take months to years if done right.

The KMT works great for all of this.

Nature's Way Kelp is collected from deep in the ocean because Kelp close to shore may absorb many heavy metals and toxins.

I developed an overactive thyroid from taking too much kelp. My ND told me not to use it, as the thyroid is very senstive. I must say I felt great on it though until this happened.
