Armour versus Levothyroxine

I have been to see my Endo today and told him that I have been very tired lately and my ankles were swelling and I wasn't sleeping. He informed me that I was running out of options as the T3 he gave me contained wheat and I couldn't tolerate it and was not prepared to pay £375.00 for the alternative. The only other alternative was to take more Levothyroxine and then if that didn't work try Armour.

Now I am confused, first he wants me to take T3 which I couldn't tolerate and now he wants me to increase my Levothyroxine. The T4 apparently is below mid range and he wants it to be much higher and the Vitamin D is very low.

As I have put on a significant amount of weight since my thyroid problems began and then more when I went on Levothyroxine, I do not really want to increase the dosage.

Any advice would be much appreciated - he wouldn't let me have my blood results.

If you are sensitive there are two NDTs (Nature-throid and WP thyroid) that are hypo-allergenic and made by the same company. Someone will correct me if wrong but I think Armour is the more expensive.

If you didn't feel well on levothyroxine I doubt whether a higher dose will suit, but it could do. If he will prescribe Armour he might prescribe either of the two above and there have been no inconsistencies


Saffiepurple, the Data Protection Act entitles patients to their test results. Contact your GP receptionist or practice manager and ask for your results. If they refuse make a written subject access request. There should be no charge for results requested with 40 days of testing but practices may make a nominal £1/£2 charge for printer ink and paper.

There is no wheat in UK Mercury Pharma T3.

Some people don't tolerate MP T3 well so you might have better results by trying other brands bought affordably without prescription on the internet. If your intolerance is to synthetic T3 you may do better on Armour or other NDT but it is not usually prescribed on NHS and most people using it buy it on the internet.

Increasing Levothyroxine dose to raise FT4 level should improve T4 to T3 conversion and raise FT3.

Low vitD needs supplementing. If you say how low your vitD is I can suggest how much to supplement.
