T3 Uptake

T3 uptake is a metric for how much active thyroid hormone T3 is biologically available to the body. This can provide important information on thyroid health.

Thyroid stimulating hormone (TSH) is a measure of thyroid health. The thyroid hormones govern metabolism, or the body’s energy production. Poor thyroid function be caused by and can contribute to stress. Stress inhibits thyroid hormone production and utilization, and the stress systems tend to take over to compensate for low thyroid function. Thyroid function is vital for maintaining gut health, too. Thyroid hormones govern the growth and proliferation of the cells in the gut, and promote gut motility, support the immune system, and enhance digestive enzyme and stomach acid secretion. Low thyroid function is common in aging and several chronic and age related diseases, as energy metabolism is what fundamentally maintains the structure and function of every cell, tissue and organ system in the body.
