About Pure Encapsulations - Selenium
Pure Encapsulations Selenium delivers 200 mcg of selenomethionine, an organically bound form of selenium with well-studied absorption characteristics, in a single daily capsule. This trace mineral supports thyroid hormone metabolism, antioxidant enzyme activity via glutathione peroxidase, and immune system function. It's formulated for adults seeking foundational micronutrient support in a clean, hypoallergenic base.
Why It's Worth Considering: Pure Encapsulations uses selenomethionine, a bioavailable, amino acid-bound form, rather than less-absorbed inorganic selenite or selenate, consistent with the brand's practitioner-grade manufacturing standards.

Frequently Taken Together
Frequently Asked Questions
-
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.
