I started taking NDT (NP Thyroid) two months ago, after taking Levothyroxine (120mg) for 10 years for diagnosed Hashimoto's Thyroiditis. I've been on a two grain dose for six weeks now although I still have some of the symptoms that have been plaguing me: insomnia, anxiety, brain fog, very cold feet, dramatic hairloss (alopecia areata) etc
My NHS GP is supportive and focused on symptoms although doesn't really know much about NDT so although I had a blood test including FT3 last week he didn't really know what to say...
Serum free T4 level 14 pmol/L [9.0 - 25.0]
Serum TSH level 0.17 miu/L [0.3 - 5.0] - Outside reference range
Serum free triiodothyronine level 11.1 pmol/L [3.5 - 6.5] - Outside reference range
Note: I took my meds at about 7.30am and the test was at 9.30am. I'm also taking the full two grain in the morning as taking even a half grain in the afternoon seems to make it hard for me to fall asleep.
I guess the question is whether to increase and see whether that helps the symptoms or decrease to address the high FT3 levels?
Other things to note:
Also, although my Vit B12 and D levels were fine, I've been taking supplements for about six months: magnesium (for sleep), B-complex, Vit D, Iron. I been having palpitations so that could be the FT3 or the magnesium. I've come off all these supplements for now to see and the palpitations seem to have stopped so it might be that was the problem.
I've also been off gluten since November (after reading Izabella Wentz's book). I did a full hormone panel in March (DUTCH urine test) which indicated that my adrenal function was normal although I was very estrogen dominant - so I'm using a progesterone cream. Another test showed below range glutathione, so I'm also supplementing that.
Hopefully all of this will help but advise on NDT dosing would be very welcome!
