What is Pure Encapsulations Selenium, and what is it used for?
A 60-vegetarian-capsule supplement providing 200 mcg of selenium as organic selenomethionine per capsule, taken 1–2 times daily with food. Selenium is an essential trace mineral required for synthesizing selenoproteins including glutathione peroxidase and thyroid deiodinase enzymes — critical for antioxidant defence, thyroid hormone conversion (T4 to T3), and immune regulation. Selenium intake is often insufficient in North America due to depleted soil concentrations in many growing regions.
What is in Pure Encapsulations Selenium, and why is the form important?
Each vegetarian capsule contains 200 mcg of selenium as selenomethionine — the organic, amino acid-bound form. The body recognizes selenomethionine as the amino acid methionine, incorporates it directly into protein stores, and uses it as needed — providing superior bioavailability (approximately 90%) and retention compared to inorganic selenite (approximately 60% absorption), which is more rapidly excreted. Excipients: hypoallergenic plant fiber cellulose, HPMC capsule, purified water, and ascorbyl palmitate only. No magnesium stearate, no fillers, no common allergens.
Who should take Pure Encapsulations Selenium, and how is it used?
For adults seeking immune support, thyroid health (particularly those with autoimmune thyroid conditions such as Hashimoto's or Graves' disease), or antioxidant defence — especially those in selenium-deficient regions. Take 1–2 vegetarian capsules daily with food. Do not exceed the recommended dose as excess selenium causes toxicity. Consult a physician if pregnant or breastfeeding. Those with a history of non-melanoma skin cancer should consult a physician before use, as higher selenium intakes have been associated with increased recurrence risk in this specific group.
How does Pure Encapsulations Selenium differ from other selenium supplements?
The selenium form — organic selenomethionine — provides approximately 90% bioavailability versus roughly 60% for inorganic selenite, the cheaper form in most mass-market selenium products. Organic selenium is stored in body proteins and released as needed, whereas inorganic selenium is more rapidly excreted. Pure Encapsulations' excipient list contains only plant fiber, HPMC, water, and ascorbyl palmitate — no magnesium stearate (a common lubricant that can impair nutrient absorption), no fillers, no binders. This minimal excipient profile is specifically designed for individuals with complex food sensitivities or those following clinical elimination protocols.
