Thanks for everyone here for educating me, I have managed to get my iron levels to a higher levels they may have ever been! I'm so pleased and hopefully they'll continue going up. I have used the Heme iron recommended by many here.
It's been one year since I was diagnosed with hypothyroidism and I'm now on 12.5mch of Levo and 60mcg of Liothyronine a day, and feel the best I have in 4 years (since I fell pregnant with my daughter). I don't tolerate levothyroxine well and feel rubbish on anything over 25mcg, but I tried to remove it altogether and my air hunger came back almost immediately. So this balance is working really well for me. My latest test results showed a pretty non existent TSH, a very low t4 and t3 just over the range. My consultant is happy to keep me on my current medication as I feel so good as long as I don't have heart palpitations (which I don't) inw which case he said to reduce the t3 to 50mcg a day. I think I am very lucky to have found such a good endo.
I have started eating a ketogenic diet as I have been doing a lot of research and there is a firm link between thyroid issues and insulin resistance. I'm 6kg down in one month. This is a very restrictive diet and is not for everyone but is working very well for me.
I have also been able to come off my antidepressants for the first time since I had my daughter, I firmly believe my depression was thyroid linked as it went as soon as my t3 levels increased.
I am not sure why I am sharing but hopefully it might help someone else!
