Support thyroid function and antioxidant defence with organic selenium
Each capsule provides 200mcg of selenium bound to the amino acid methionine (selenomethionine). This is the organic form of selenium that is incorporated directly into body proteins in place of methionine, creating a selenium reserve that the body can draw on when needed. Selenomethionine has the highest overall bioavailability of the selenium forms and is the form most commonly used in clinical research on selenium and thyroid function, immune health and antioxidant support.
Selenium is an essential trace mineral required for the production of selenoproteins, which include the glutathione peroxidase family (critical antioxidant enzymes), the thioredoxin reductases (cellular redox regulation) and the deiodinase enzymes (thyroid hormone conversion from T4 to active T3). At 200mcg (364% NRV), this provides a beneficial dose appropriate for those with confirmed low selenium status, thyroid support or immune system requirements. The vegetarian capsule shell makes this suitable for most dietary requirements.
Key benefits:
- Thyroid support and hormone conversion
- Cell support for DNA integrity
- Organic form for better retention
| Each capsule contains: | Amount | %NRV* |
|---|---|---|
| Selenium | 200 mcg | 364% |
† Nutrient Reference Value (NRV*) not established
Cellulose, Hydroxypropyl Methylcellulose (capsule), Di Calcium Phosphate, Selenium Methionine.
Directions for use:
Take 1 capsule per day with food.
Taking with a meal supports absorption and is the standard recommendation for selenomethionine. This form builds tissue selenium stores over time, making it ideal for general selenium maintenance and long term support.
If choosing between this product and Selenium SeMSC, the key difference is form and application. Selenomethionine is the better general purpose choice for building selenium stores and supporting thyroid and immune function. Selenium SeMSC (methylselenocysteine) is a more targeted form that does not incorporate into body proteins and is instead metabolised directly to methylselenol, which has specific research relevance for cellular support.
