Your still a bit under medicated

You may find your need for vitamin D supplements decreases once optimally medicated.


Should I increase Nature Throid or Cytomel



If you feel great you are optimally dosed even if thyroid levels appear to say otherwise.

TSH is very suppressed. FT4 is low in range but that is quite normal for people taking NDT and T3. FT3 2.7 is low in range but as long as you are feeling great I wouldn't increase dose.

Is the thyrogobulin result thyroglobulin or thyroglobulin antibodies?

TPO antibodies are negative for autoimmune thyroiditis (Hashimoto's).

What is the vitD lab ref range?

B12 is usually high when you are supplementing. If you are not supplementing it can be indicative of underlying disease and you should discuss with your GP.

Iron looks fine.
