Switching to Armour - Please advise

Hi I'm finally switching to armour after consulting with my gp and although he can't subscribe them on the NHS he is happy to monitor and work with me on how I'm feeling along with regular blood tests which is reassurance to me.

I am after some help on the level I should start on as I'm finding the mg and grain all very confusing - any advice would be gratefully received

Many thanks

1 grain Armour is 60mg and contains 38mcg T4 and 9mcg T3 which is equivalent to 65mcg Levothyroxine.

Many thanks - would you recommend starting on a smaller dose and build up ?

hopefully get started asap and see some improvements 👍


What is your current Levothyroxine dose? If you have recent TSH, FT4 and FT4 results and ranges please post them too.
