Thyroid UK

1st post, advice please

Hi Ive been on this a while now, never needed to post before.

I have just recently decided to purchase thyroid s.

I have had in the past lots tests all coming back ok, never had T3 tests though

still have aches pains stomach acid, (getting better with that with acupuncture)

really getting to the stage where I need to try something else.

Ive been on levothyroxine for 6 years now, 125mg per day.

is there any particular other tests I should get done before starting.

I have done my homework, not a sudden decision this.

any info would be most helpful.

thanks Pammie.xx

I think you should get a TSH, T4, T3, Free T4 and Free T3. (I know GP won't do them all) so you have a starting post in swapping from levo to NDT. You will have a comparison to work with. If you haven't had a recent B12, Vit D, iron, ferritin and folate ask GP for these too if you haven't had them for a while. I think the NHS does these yearly if necessary.

I am sure your switchover will be successful.


Happydaze, You can switch to Thyroid-S without further tests but it will be useful to have FT3 tested after 6/8 weeks to check T3 isn't going over range. Igrain NDT is roughly equivalent to 75mcg-100mcg Levothyroxine. Reduce Levothyroxine to 50mcg and start with 1 grain initially to accustom yourself to the T3 in Thyroid-S. After 2 weeks you can stop Levothyroxine and increase Thyroid-S by half a grain, hold for two weeks and increase by half a grain a fortnight later. Hold at 2 grains for 6 weeks and have TSH, FT4 and FT3 tested before increasing further.

Hypothyroid people often have low stomach acid. Betaine Pepsin or a couple of tsp of raw apple cider vinegar in fruit juice or honey sweeetened water before meals can raise stomach acid and aid digestion.


Thanks for info on how much to take been searching everywhere for a conversion chart and couldnt find one, I was sure the sttm website had one but been a while since I saw it.


You really need to be sure that



B12 are all at least halfway in their ranges before you take NDT or any t4 meds like levothyroxine

if they are Ok you should be able to swap your 125mcg of levo for 2 tablets of thyroid-s

best though to take one in the morning and one late afternoon


Thank you all for replys, going to make app with docs before starting as not had bloods done in a while, , not sure what they will think and I know ill not get the t3 ones thou.
