Tell me more about the role of selenium in thyroid health.

Selenium is crucial for thyroid hormone production. It allows for effective interaction between iodine and the amino acid L-tyrosine, which are essential for the synthesis of thyroid hormones 1. Additionally, selenium has several health benefits beyond its role in thyroid function, including reducing risks of prostate cancer and preeclampsia, and even improving skin conditions like acne 2.

Here are some points discussed by Andrew Huberman regarding the role of selenium in thyroid health:

• Daily Requirements: The recommended daily intake of selenium varies by region, generally between 55 and 200 micrograms. For children, it's lower, around 30-40 micrograms. Overconsumption should be avoided, although the exact consequences of excessive intake are not well-documented 3.

• Sources of Selenium: Brazil nuts are one of the richest sources of selenium. Just six to eight nuts can provide about 550 micrograms. Other sources include fish, meats like pork and beef, and other foods like eggs and brown rice. However, the selenium content can greatly vary depending on the soil where the food is produced 1.

• Impact on Metabolism: Selenium contributes to metabolic regulation by enabling the production of thyroid hormones, which are crucial for energy regulation and tissue repair throughout the body 4.

It's essential to consult with a healthcare provider before altering selenium intake, given its powerful effects on thyroid function and overall metabolism.
