over medicated

I was taking 60mg of Armour but stopped a few months ago as the new batch seemed to make me feel worse. I started taking thyrogold - 3 capsules but heart has been racing ( 105 resting) and not feeling well. i had blood tests done and the doctor said I am over medicated as results were

tsh 0.01

t4 56

t3 26

massively over

last time i was tested i was under even on medication.

could just 3 tabs of thyrogold casue me to spike this much ?

any advice on what to do

Doctor is saying to drop dose and he will prescribe what i want but not sure what to do ?

Juniperwood, no wonder you feel unwell, you are massively overmedicated. FT4 top of range is usually between 22-24 and FT3 top of range 6.8-7.2.

I was told that 1 x 300mg capsule ThyroGold is equivalent to 3 grains NDT.

What were your results on 1 grain NDT?


I am not a medical professional and this information is not intended to be a substitute for medical guidance from your own doctor. Please check with your personal physician before applying any of these suggestions.


When I was on Armour my results were all in range with t4 being just below range ( sorry I forget the actual numbers and sadly didnt get a print out as GP just told me over phone. I only stopped the Armour as the new batch didnt seem the same and I start4d getting a lot of joint pains and headaches.

My God is 300mg capsule is equivalent

to 3 grains no wonder I am feeling terrible !


It is very important that your pulse and temp are regulated when first taking thyroid hormones (NDT or T3). It seems you are on too much Thyro Gold, so you definitely need a reduction.

You just cannot take willy-nilly thyroid hormones and hope for the best. As far as I know Armour 60mg is 1 grain. Equal to around 150mcg of Thyrogold.

Before you begin your pulse/temp should be noted and used as a guide when you gradually build up a dose. If your dose is 300 and clutter has stated what it is equal to you can take quarter or half a capsule. If you are taking 3 x 300 it is a massive dose. I do know there are 150mcg of capsules

You should miss a few days' doses so your system calms down.


This is an excerpt from STTM\;

THYROGOLD, called a “dietary supplement”, though patients report it working very well. Was created by the now-deceased John C. Lowe, and his wife currently sells it. Comes in 150 mg and 300 mg tablets. The mgs is NOT equivalent to the same mgs in prescription NDT tablets. i.e. 150 mg may be “similar in effect” to 1 1/4 grains, but that’s a subjective opinion by some. The thyroid powder in the tablets are from New Zealand pasture-fed cows, plus there is 25 mg of Coleus forskohlii, which is said to promote thyroid function. It is a popular OTC product!


Thanks guys

I will miss a few days and start back with half a capsule.

I didn't realise it was so strong. On reading the info on the site is says most people start with on or two caps - i obviously went in too high :(
