I have now started NDT (Naturethroid) half a tablet (equivalent to 50mcg Thyroxine) together with 100mcg of Thyroxine. I feel less of an urge to go running (was that my way of elevatiing my T3 on T4 only?) and calmer. However, after 2 and 1/2 weeks I'm now waking with a pounding heart and last two days have had what I think is angina (tight chest, tight throat, like really bad indigestion). I have been taking iron supplements but I imagine not rising quickly. Before starting NDT my levels were as follows:
Ferritin 23.30 (range 10-300)
B12 440 (range 200-950)
Iron 86 (range 50-170)
Vit D 34.90 (range 30-100
Folate 15.27 (range 3-20)
My question is: is it the T3 that needs higher iron because only T3 acts on the heart muscle, and the heart only has T3 receptors? Could it be that the angina is caused by my still low ferritin levels?
Has any one else experienced angina or palpitations in the early morning as a result of NDT?
And does any one have a suggestion of what I should do next? The angina is pretty scary!
