How do you get T3 and T4?

The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4.

How is T3 and T4 produced?

Thyroid hormones (T4 and T3) are produced by the follicular cells of the thyroid gland and are regulated by thyroid-stimulating hormone secreted by the anterior pituitary gland.

What is normal range for T3 and T4?

A normal T3 level might be somewhere between 100 to 200 nanograms per deciliter (ng/dL), while a normal T4 level falls between 5.0 to 12.0 micrograms per deciliter (μg/dL). Free T4, which tests for the amount of T4 that is available in the body, should range between 0.8 to 1.8 nanograms per deciliter (ng/dL).

Is T3 or T4 more important?

Because T4 is converted into another thyroid hormone called T3 (triiodothyronine), free T4 is the more important hormone to measure. Any changes show up in T4 first. T3 and T4 help to control how your body stores and uses energy (metabolism).

Does low T3 cause weight gain?

According to Dr. Kitahara, if someone has low thyroid function, their TSH is high, and the thyroid hormones known as T3 and T4 are low—and weight gain often occurs. If someone has an overactive thyroid or hyperthyroidism, TSH is usually low, the T3 and T4 are high, and weight loss occurs.
