In this Huberman Lab Essentials episode, I explain how two key hormones control metabolism and discuss tools to enhance their levels to improve metabolic health.

I discuss the pathways through which the brain and body interact to produce thyroid hormone and growth hormone, and how these hormones influence essential processes like tissue growth and repair, body composition, and energy production. I explain how thyroid hormone levels are influenced by key nutrients, such as iodine, selenium, and L-tyrosine. I also explain how practices such as exercise, sleep, meditation and sauna can offset age-related declines in growth hormone, to optimize overall hormone health and metabolism.

Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday.
