How can I increase my thyroid levels naturally?

To increase thyroid levels naturally, Andrew Huberman suggests focusing on ensuring adequate intake of selenium and iodine, which are essential for thyroid hormone production.

1. Selenium: This mineral is crucial for the synthesis of thyroid hormones. Foods rich in selenium include Brazil nuts, fish (like yellowfin tuna), shellfish, pork, beef, turkey, chicken, cottage cheese, eggs, and brown rice. Brazil nuts are particularly potent, with six to eight nuts providing about 550 micrograms of selenium. Be cautious with the amount, as excessive selenium can be harmful 1.

2. Iodine: Adequate iodine levels are necessary for thyroid hormone production. It can be obtained through iodized salt, kelp, and seaweed. People with diets high in cruciferous vegetables, which can interfere with thyroid function, should pay extra attention to their iodine intake 2.

Additionally, maintaining a balanced diet that includes essential fatty acids, gut health (with fermented foods), and proper sleep can contribute to overall metabolism and thyroid function 3. As always, consulting with a healthcare professional before making dietary changes is advisable.
