what is T4 for?

[Guest guest]

There's some different takes on T4 and wether we need it or not, so I'd like to get some opinions here on what it's even for?I've noticed that if I take Armour it lifts my mood, but not so with just T3.  Is T4 responsible for any brain functions?

Hi Elyse

If you want to know about thyroxine - read its story here http://pubs.acs.org/cen/coverstory/83/8325/8325thyroxine.html

For the majority of sufferers of hypothyroidism, it appears that

thyroxine alone does appear to work OK for them, but we never really know

whether these patients are feeling as well as they could be. Thyroxine is

needed by the brain - one of the symptoms many of us suffer with hypothyroidism

is brain fog and short term memory, and this is because it is not getting the

thyroid hormone it needs. However, although thyroxine is the dominant hormone

secreted by the thyroid gland, because it is mainly inactive hormone, it

needs to convert through the liver, kidneys and other thyroid receptors to the

active hormone T3- and it is T3 your body needs to make it function. Armour

life your mood because it contains T4, T3, T2, T1 and calcitonin - so you are

getting the full benefit of all the thyroid hormones your body requires.
