Practitioner-grade selenium by Ortho Molecular Products
Ortho Molecular Products' Selenium delivers this essential trace mineral in a practitioner-formulated supplement designed to support antioxidant defense, thyroid hormone metabolism, and immune function. Selenium plays a key role in glutathione peroxidase activity, making it relevant for those seeking cellular protection from oxidative stress.
Why It's Worth Considering: Ortho Molecular Products is a practitioner-grade brand known for rigorous quality standards and clinically relevant dosing, making this a reliable option for individuals working with a healthcare provider on targeted micronutrient support.
For maintenance: 100-200mcg daily (selenomethionine form preferred). For thyroid support: 200mcg. The RDA is 55mcg but most functional medicine practitioners recommend 100-200mcg. Do NOT exceed 400mcg/day — selenium has a narrow therapeutic window and excess causes selenosis (hair loss, nail brittleness, GI issues).
Yes — selenium is critical for thyroid function. It's required for the enzyme that converts inactive T4 to active T3, AND it protects thyroid cells from oxidative damage. In Hashimoto's, 200mcg selenium daily reduces TPO antibodies by 20-40% in clinical trials. It's one of the most evidence-based supplements for thyroid health.
One Brazil nut contains 70-90mcg selenium — so 2 nuts/day provides a therapeutic dose. However, selenium content varies dramatically by soil (some nuts have 10mcg, others have 300mcg). If you rely on Brazil nuts, be cautious about overconsumption — 4-5 large nuts could exceed 400mcg. A supplement provides a consistent, known dose.
