Could anyone cast their eye on my latest and odd thyroid results please?

I am on nature throid and have been so a while. Last results whilst I was on one grain showed that I was probably under medicated. These are the results here

TSh 4.33 range .02 -4.2

T3 3.9 range 3.95-6.8

T4 10.4 range 12-22

I upped my dose to 1 1/2 grains and have these latest results,

TSh 0.13 range 0.25-5

T3 4 range 3.5-6.5

T4 9.1 range 9 -23

I'm a bit bemused. I've never had a tsh so low, I certainly don't feel in any way over medicated. Yet my T3 and T4 are still on the low side.

Thoughts anyone? Thank you!

Your TSH is irrelevant on any meds containing T3. Your FT4 & FT3 are still too low, indicating under medication, in my view.

I am optimal at FT4 17 & FT3 above 6.

TSH is nearly always suppressed if you take any amount of T3. Though many doctors try to use the TSH as a guide to dosage it's no use at all for adjusting T3 and NDT doses.

You need a raise in dose - you should feel a lot better once the FT3 is in the top part of the range.

The blood tests were introduced along with levothyroxine, so they don't quite fit with NDT as it contains a combination of thyroid hormones.

I shall give you a couple of links which might be helpful. The best way, I believe, if taking other than levo is 'how we feel'. If we take too much we'd go by our symptoms and reduce (I also take pulse/temp several times a day when on NDT or T3 only). A very fast heart rate or sweats are also indicative of too much.

exerpts from last link:

Our treatment team uses the TSH level only initially to help clarify a patient’s thyroid status. But during treatment, we completely ignore the level. The reason is that the TSH level is totally irrelevant to normalizing the patient’s whole body metabolism and relieving his or her suffering. The only clinical value of the TSH level is to see the effect of a particular dose of thyroid hormone on the pituitary gland’s "thyrotroph" (TSH-secreting) cells.
