Thorne Selenium 200mcg Capsules - L-Selenomethionine

Thyroid Function Optimization: Selenium is essential for converting inactive thyroid hormone T4 (thyroxine) into its active T3 (triiodothyronine) form, which regulates metabolism, energy production, and body temperature. As a cofactor for deiodinase enzymes, selenium ensures optimal thyroid hormone activity, supporting healthy metabolic function and helping maintain balanced thyroid status in healthy individuals.

Powerful Antioxidant Defence: As a critical component of glutathione peroxidase and superoxide dismutase (SOD) enzyme systems, selenium acts as both a direct antioxidant and an antioxidant cofactor. This dual action neutralizes hydrogen peroxide and lipid peroxides throughout the body, protecting cell membranes, DNA, and proteins from oxidative damage caused by environmental toxins, stress, and normal metabolic processes.

Cellular Health & Development: Selenium supports normal cell differentiation and function across multiple organ systems, including the heart, liver, eyes, and connective tissues. By maintaining optimal selenium status, you support healthy gene expression and cellular signalling pathways that influence tissue repair, immune cell function, and overall cellular integrity throughout the body.

Heavy Metal Detoxification Support: Research indicates that selenium may provide protective effects against mercury, cadmium, and other heavy metal toxicities by binding to these harmful metals and facilitating their elimination. The L-selenomethionine form in this formula offers superior bioavailability, ensuring efficient uptake and utilization for detoxification support and protection against environmental heavy metal exposure.
