Paul Jaminet's blog has plenty of info on treating hypothyroidism.
Tho its time consuming trawling through all the information, as their many posts and comments on the subject & associated topics. but its well worth the time.

Here are a couple of searches to get you started;

suggested blood tests for thyroid are; tsh, ft3, ft4, rt3
(if you have Adrenal/Stress issues as well, typical saliva tests are DHEA-S & 4 x Cortisol to start with & possibly midnight & morning Melatonin if sleep is bad).

Armour Thyroid is available again (at least in my city). I take a combo of Synthroid for the T4 and Armour for the T3. But, I have to say that the change that made the biggest impact on my Hashimoto's symptoms was going 100% Paleo.

Thyiodine is what I take. Thyroid and adrenals freeze dried in there.

After I was diagnosed with hypothyroidism, I was reluctant to take drugs, so I went the route of supplements - L-tyrosine, selenium, iodine, zinc, along with my regular multi. That wasn't enough to bring me into the right range, though, and I'm now on Synthroid.

I still supplement with those things in the hopes of minimizing my required dosage, though my doc doesn't like the selenium because it can counteract the Synthroid....or something like that.

As far as dietary changes, I also stay away from uncooked cruciferous veggies like cauliflower, broccoli, spinach, and cabbage. Apparently, if your thyroid is already weak, these things further inhibit thyroid function.

So to answer your question, I was not able to fully treat hypo without a doctor or meds, though there are steps I take thru supplements and my diet. I've not heard of Thyrogold and will check it out!

I want to share my grandmother's experience as a cautionary tale about self treatment of thyroid imbalance...not to tell anyone they should or shouldn't, only to encourage people to be extremely informed about something so serious. My grandmother was diagnosed as low thyroid years ago, and was prescribed armour thyroid. She took it for years at the same original dose, even after she relocated out of state and didn't find a new physician to test her thyroid levels...the original doctor continued to renew her prescription for years without knowing what her hormone levels were...then he suddenly didn't renew it, and she was off her medication altogether, we're not sure how long this went on for...we're in Oregon, and she had moved to Florida...for the sake of attempting to make a long and tragic story a tad more abbreviated I'll skip over some middle here...my grandmother ended up in the hospital after months of cognitive decline with the most whacked out thyroid the neurologist had EVER seen, apparently, her being alive at all was miraculous at this point...she'd been taking thyroid glandular for so long without having her levels tested that she'd slipped into hyper thyroid which had gone to the extreme...she passed on after a couple months of pain and severe confusion...

I was diagnosed hypothyroid (TSH 33) in 2005 with no known cause, doc said "it is what it is". Put me on Synthroid, adjusted dose til my TSH was around 1.5. I took it for almost 6 years. Started paleo in Jan 2011. Within months my BP, chol, trigs, weight, gout...everything...was better. I asked doc if I could quit Synthroid--he said, "no, it's for life". I quit anyway. TSH is now 2.5 with no meds.

What really pisses me off is that they never tested anything except TSH. I know now they should have checked thyroid antibodies, reverse T3/T4, and ruled out other stuff before putting me on Synthroid.

Iodine is the worst thing to take for hypothyroidism.

Stop eating grains, and the hashi's attack will go away. My Hashi's remitted to normal range when I stopped eating corn, it was not enough to not eat glutten you have to lay off rice, gluten, corn, and processed junk food. Eat paleo.

Meds are required to increase T3, but you have to have iron, D, mag, zinc levels checked otherwise the treatment won't stick...keep reading about the subject from reputable sources.

Insofar as I "treat" mine, its only by taking care of myself. I also have to eat less- maybe 1500 calories- than perhaps most Paleos can. But I take a lot of vitamin D3 and a very good chelated multimineral, and do a decent amount of cardio. This seems to keep it under control. I also follow the autoimmune protocol- no egg whites, very few nuts, and no (okay, not many) nightshades. However, that's just because I have Hashimoto's, so not applicable in your case.
