Ok after still feeling depressed and unwell, just received blood results from blue horizon.

GP wants to reduce Levi, I'm on 100mcg aday. I am very reluctant as I am worried that I will feel worse.

TSH 0.09 Range 0.27 - 4.20

T4 total 120 Range 64.5 - 142.0

Free T4 17.94 12 - 22

Free T3 4.40 3.1 - 6.8

Anti- thyroidperoxidase abs 12.1 <34

Anti- thyroid globulin abs 20.4 <115

Ferritin 65.4 20 - 150

Vit D 61insufficient 25-50

Bit B12 532

Folate 16.81

Anybody got any thoughts or advice.

You will feel worse, I'm afraid, because your FT3 - the most important number - will drop even further - and it's already too low.

You need an increase, not a reduction, but your doctor is only looking at the TSH. He doesn't know much about thyroid. Once you are on thyroid hormone replacement, the TSH is irrelevant. It's the FT3 he should be looking at, and most people need that to be up near the top of the range to feel well.

I'm afraid I don't know what you can do about doctors who don't understand the basics, except explain that you don't want your dose reduced because you are still hypo, your FT3 is still too low, 100 mcg is little more than a starter dose, and it really doesn't matter how low the TSH goes, it won't do you any harm.

And, if he starts going on about osteoporosis and heart attacks - all of which is false - then tell him you're willing to take the risk in order to feel well now. He is there to advise you, not dictate to you. And, if he still won't raise your dose, buy your own! This man is just going to make you sick.


bazs I agree with Greygoose, you need an increase, possibly a little T3. But you should also look at your vitamins and minerals as they're not optimal and need to be for thyroid hormone to work properly.

Vit D needs to be 100-150 so needs supplementing.

B12 should be at the top of the range, even 900-100 so you need to take sublingual methylcobalamin lozenges along with a B Complex to balance the B vits.

Folate needs increasing to at least half way through the range but the B Complex will take care of that as long as it contains methylfolate.

Ferritin needs to be half way through range and an absolute minimum of 70.

Also, supplementing with selenium will help conversion of T4 to T3 and that may be enough to increase your FT3 in relation to your FT4.

Thank you for that off to the chemist x


To be honest bazs you'll get better supplements on the internet.

For Vit D you need D3 - 5000iu daily for maybe 2-3 months then reduce to 5000iu alternate days. Keep an eye on your level, get a fingerprick blood spot test from City Assays unless you're repeating the BH test. City Assays recommend testing once or two year to avoid reaching toxicity level. I like this one , no unnecessary ingredients.

When taking D3 we also need K2-MK7 and magnesium as they are both co-factors. Vit D aids absorption of calcium from food and K2 directs the calcium to bones and teeth rather than arteries and soft tissues. Both K2 and D3 are fat soluble and need to be taken with dietary fat such as the fattiest meal of the day. Magnesium is calming and best taken in the evening.

B12 should be Solgar or Jarrows sublingual methylcobalamin lozenges 500mcg daily for a couple of months then reduce to 1000mcg daily. Let it dissolve under the tongue and it gets directly into the bloodstream, don't chew or swallow as stomach acid destroys it.

For the B Complex go for Thorne Basic B or Jarrows B Right.

For ferritin you might be OK with just eating iron rich food regularly, such as liver once a week. Try that and see if your level improves, if not you could consider Solgar Gentle Iron.
