He's also written to my GP for a Vit D prescription ( 35 ) >70 and is going to take a load of bloods next week, as he said Im low in so many things....B12, Folate, Calcium, Cortisol. Sodium etc. He also wants to add a little T3 to the Nature Throid I'm taking to get my TSH levels back down to a normal level,which is (25) at the mo and also my Free T3 and Free T4 up that are below range. T3 gave me headaches daily last time I tried it with Levo, hoping it won't happen with NDT. Any thoughts Guys?
