What does free T4 do in your body?
Free T4 (thyroxine) is the hormone your thyroid produces the most of. It circulates in the blood and is converted to the active T3 in your body's cells. If T4 is too low or too high, it can affect everything from your energy and weight to your menstrual cycle and fertility.

“An amazing and incredibly important product! Easy to use and provided informative and clear information about my fertility. Highly recommend!”

“Good instructions on how to perform the test, nice to have both a summary and more detailed information about the different parts of the results.”
“The most wonderful treatment and I still have great contact with you. So incredibly grateful for what you do. So happy that I got to experience the wonderful thing you've created.”

Thyroid
Free T4 — Free Thyroxine
Think of free T4 as the fuel storage - it's the hormone your thyroid produces the most of, ready to be converted into energy when your body needs it.
What does it do?
T4 is produced in the thyroid gland and is the main hormone form released into the blood. Free T4 is the portion not bound to proteins and therefore available to your body's cells. In the cells, T4 is converted to T3, the active form that directly affects metabolism.
Why does it matter?
Free T4 gives a direct picture of what your thyroid is actually producing. Together with TSH, it helps distinguish between different types of thyroid problems. Abnormal T4 levels can affect your energy, weight, skin, hair, and reproductive health.
