First test results since starting NDT

My test results have come back since starting Thiroyd 8 weeks ago. I take half first thing in morning and now recognise when I need the other half early afternoon. I sometimes feel low at teatime. My results are free T4 11.2 (12-22), TSH 0.04 (0.3-4.2), free T3 5.4 (3.1-6.8) and ferritin 63 (12-230). I was on 50mcg levothyroxine. Are these where they should be for optimal, I am not sleeping well and sometimes get stiff and painful joints although I went to a party on Saturday and danced all evening, it seems to vary from day to day. Sometimes I get muscle pains at night which keep me awake. I also need to eat bananas, I find three a day make me feel better.

Dramlouie, you might try another 1/2 grain to see whether muscle and joint pain improves. FT4 is below range which isn't unusual when on NDT, and FT3 5.4 is good, but there is room for an increase. Taking the additional 1/2 grain at bedtime may improve sleep. If it doesn't add it to your morning dose.

Ferritin is optimal >100 through to half way in range. Supplement iron with 500mg-1,000mg vitamin C to aid absorption and minimise constipation.

I wonder if you can tell me what dose of Thiroyd you have been taking and how you decided to divide your dose. I have been taking 50 mg of levothyroxine until about three months ago when I started taking 30 mg of armour thyroid. I was happy with my initial response - much better than levothyroxine - but the last month has not been as good. I'd like to give Thiroyd a try. Can you suggest anything?


Stiff and painful joints can be down to being low or deficient in vitamin D.

Vitamin D the sunshine vitamin. Many complain of joints aching more in winter.

85% of us in Uk are either low or deficient and do not know it.
