Technical notes
Research Profile
Supplement Facts per one capsule: Selenium (as L-Selenomethionine) 200 mcg, 364% DV.
L-selenomethionine is the organic, amino-acid-bound form of selenium found in food, and is well absorbed and readily incorporated into selenoproteins. Selenium is an essential cofactor for the glutathione peroxidase and thioredoxin reductase antioxidant enzyme families, and for the deiodinases that convert thyroid hormone T4 to active T3.
Label claims: supports immune system health, antioxidant support, and thyroid function. High potency, essential mineral.
Other ingredients: microcrystalline cellulose, hypromellose (derived from cellulose) capsule.
Suggested use: as a dietary supplement, take one capsule daily or as recommended by a healthcare professional. Caution: do not exceed the recommended dose — selenium has a narrow intake range and chronic excess intake is not advised. Pregnant or nursing mothers, children under 18, and individuals with a known medical condition should consult a physician before use. Keep out of reach of children.

AI Dosing & Reconstitution Assistant
Enter your vial, diluent, and target aliquot in any unit — mcg, mg, g, mL, µL, or U-100 syringe units. Every value is range-checked before generation, and the assistant returns concentration, draw volume, and a reconstitution workflow tailored to Selenium 200 mcg.
Inputs are inside normal laboratory ranges: 5 mg/mL, draw 0.05 mL (5 U), ~40 aliquots per vial · aliquot = 250 mcg.
Draw volume in every unit: 0.05 mL · 50 µL · 5 U.
Target aliquot: 250 mcg · 0.25 mg · 0.0003 g.
