Does iodine help convert T4 to T3?
The majority of our T3 however comes from a process called deiodination, which takes place in our peripheral tissues (such as the liver and kidney) via the activity of two enzymes called deiodinase 1 and 2. During this process, an iodine molecule is removed from the hormone T4, converting it into its active form, T3.
Why is iodine needed for thyroid function?
