Frequently Asked Questions
Is it possible to get too much selenium?+
Yes, selenium has a narrower margin between optimal and toxic intake than most minerals. The upper tolerable limit is 400 mcg per day, and the optimal supplemental dose for most adults is 100-200 mcg. Read all label information before beginning use.
How does selenium support the thyroid specifically?+
The thyroid is the most selenium-rich organ in the body per gram of tissue. Selenium is an essential cofactor for iodothyronine deiodinase, the enzyme that converts the prohormone T4 into active T3. Read all label information before beginning use.
Can selenium help reduce thyroid antibodies in Hashimoto's?+
Yes, selenium supplementation (200 mcg daily as selenomethionine) has demonstrated significant reduction in TPO antibodies and anti-thyroglobulin antibodies in multiple clinical trials of Hashimoto's patients.
Is selenomethionine better than sodium selenite?+
L-selenomethionine is the organic, food-form selenium, found naturally in Brazil nuts and selenium-rich vegetables. It is the most bioavailable form and has the best retention in the body. Start with the lowest recommended dose and adjust as needed.
How many Brazil nuts do I need to eat to get 200 mcg of selenium?+
Brazil nuts are the richest food source of selenium. One average-sized nut provides about 68 to 90 mcg. So 2 to 3 Brazil nuts per day can cover a full daily need. Pair with a balanced diet for the best results.
